GENERAL SAFETY INSTRUCTIONSThe operation of a Bituminous Distributor normally requires handling of liquid products at elevated tempera-

ture. Also, these liquids may be of a volatile nature. A heating system is supplied to raise or maintain the producttemperature, and these systems use highly combustible fuels. As with any type of construction equipment, there arecertain hazards associated with careless or improper operation.

Safety warnings have been provided to call attention to any potentially hazardous situation that may causeproperty damage, personal injury or death to the operator or bystanders. These safety warnings will be shown atvarious times throughout this manual, as they are applicable to the subject being presented. These safety warnings areidentified by the following warning symbols:

Safety Precautions, Hazard Seriousness LevelYou will find safety information boxes throughout this manual. These boxes contain information alerting you to

situations or actions to avoid.

Signal words (DANGER, WARNING and CAUTION) are used to identify levels of hazard seriousness. Theirselection is based on the likely consequence of human interaction with a hazard. Definitions of hazard levels are asfollows.

DANGER - Immediate hazards which will result in severe personal injury or death.

WARNING - Hazards or unsafe practices which could result in severe personal injury ordeath.

CAUTION - Hazards or unsafe practices which could result in minor personal injury or prod-uct or property damage.

All of these warnings are listed below and they also appear throughout the manual. In addition to these, you willfind notes throughout the manual.

NOTE - A note provides general information that the operator should be aware of when performingan operation.

DANGER

To avoid an extreme fire hazard or explosion,NEVER use gasoline as fuel in low pressure orgenerating burners.

WARNING

A fully charged dry chemical type fireextinguisher must be within easy reachwhenever the burners are operating or there isan open flame near the distributor. Theminimum capacity of the fire extinguishershould be 10 pounds.

6

WARNING

To prevent an explosion or fire hazard: Positionthe unit broadside to the wind to preventvolatile fumes from drifting toward the burners.

To prevent an explosion or fire hazard: Do notoperate the burners if the tank is damaged orleaking

To prevent an explosion or fire hazard: Ensurethat the burners are extinguished beforeremoving any material from the tank in anymanner. Liquid petroleum (LP) burners cansupport a flame for several minutes after thefuel supply is turned off.

To prevent an explosion: Do not operate theburners when the vehicle is unattended, whenthe vehicle is in motion, or with the vehicle in aconfined area.

To prevent an explosion or fire hazard: Whenthe burners go out, shut off the fuel supply toboth burners and allow the flues to ventilate forat least 3 minutes before re-lighting theburners.

To prevent an explosion or fire hazard: Do notheat the material beyond the manufacturer’srecommended temperature.

To prevent an explosion or fire hazard: Keepburning cigarettes or other sources ofcombustion away from manholes and overflowvents.

To prevent possible hand or facial burns:Always light the inside burner first. Do notreach across a lit burner to light or re-light theinside burner. Shut off the outside burnerbefore lighting the inside burner.

To prevent possible burns: Always use a torchto light the burners. Never attempt to light theburners using a match or pocket lighter.

WARNING

To prevent an explosion or fire hazard: Checkthe tank vent to insure that it is free fromobstruction before lighting the burners.

To prevent an explosion or fire hazard: Do notoperate the burners with the manhole open oropen the manhole while the burners are inoperation.

To prevent possible burns to operators orbystanders, or possible equipment damage, donot start any operation if any control settingsare unknown.

To prevent possible burns from leakingmaterial: Be sure all pipe, cap and hoseconnections are secure before opening valves,or beginning any operation.

To prevent possible burns from hot asphaltspray: Do not stand, or allow anyone to stand,where accidental opening of a valve maycause contact with hot asphalt.

To prevent an explosion or fire hazard: Keeparea free of all sources of combustion whenspraying.

To prevent possible burns from foaming orviolent eruption, do not load tank with materialtemperature over 200ºF if water orcondensation is present in tank, or if emulsionwas used in the previous load. Do not heatmaterial over 200ºF if moisture or emulsifiedmaterial is present in tank.

To prevent an explosion or fire hazard:Eliminate sparks from engine exhaust.

To prevent burns from hot asphalt whenhandspraying: Hold the handspray gun inproper position and watch for other people.

To prevent burns: Always wear insulatedgloves when handling spray bar sections orhoses.

7

WARNING

To prevent severe injury from becomingentangled in machinery: Stand clear of rotatingdrives.

To prevent possible injury: Always open themanhole cover slowly. Pressure build up in thetank may cause the cover to burst open.

To prevent possible fire hazards, burns or falls:Keep the unit clean for safe operation.

To prevent possible burns from materialoverflow: Allow sufficient space in the tank forexpansion of the material when heating

Before removing the fill line cap, make certainthat the asphalt pump is turning and thesuction valve is closed.

To prevent possible personal injury: Do notload the vehicle beyond the GAWR or GVWR.The maximum load volume must be calculatedbased on material density

To prevent possible burns: Use extremecaution when using a torch to heat the pump.Asphalt accumulated around the pump mayignite when heating the pump with a torch

Allowing the burners to operate for a longperiod of time without circulating can damagethe product and create explosive fumes. Ifproduct cannot be circulated after fifteenminutes of heating without circulation, theburners should be extinguished for 20 - 30minutes before re-lighting the burners.

To prevent burns: Always wear eye protection,long sleeve shirt, insulated gloves, boots, andlong pants outside the boots when workingaround the distributor.

To prevent an explosion or fire hazard: Flues,must be covered by a minimum 6 inches ofmaterial (bitumen) when burners are inoperation

Use the measuring stick as shown in figure 2 on page21 to determine the amount of product in the tank be-fore lighting burners. The minimum amounts shownon the warning placard only apply if the tank is level.Remember that the measuring stick is accurate onlywhen the tank is level. If the tank is not level, reposi-tion the distributor to place the tank in a level positionbefore taking final measurement. You must have at leastthe amounts shown, with the tank level, in order to safelylight the lower burner and upper burner respectively.Failure to have the appropriate amount, accuratelymeasured can result in an explosion causing deathor serious injury.

9. Digital Display Screen

The digital display shows the application rate in gal-lons/sq yd on the upper line of the display. The lowerline shows the speed in fpm on the left side and thepump rate in gpm on the right side. Pushing the changedisplay button once will move you to the next screenwhich shows the feet of bar selected, feet traveled andthe gallons sprayed since the last time the reset gallonsbutton or reset feet button was pushed. Pushing thechange display button again will move you to the next

screen which displays the sq. yd. shot since the last timethe reset buttons were pushed simultaneously. Pushingthe change display button again will move you to thenext screen which displays the material temperature(optional). Pushing the change display button again willmove you to the next screen which displays the startup factor. The start up factor sets how the spray barwill act when it is first turned on. It is adjusted usingthe Application Rate switch. The start up factor is nor-mally set at 100% from the factory. If the start is thin orweak, you can increase the start up factor to compen-sate for this. A higher number will make the beginningof the shot more aggressive or fatter. You may have tochange the start up factor by as much as 25 to 30% tosee the appropriate change. Conversely if the start ofthe shot is too fat and heavy you would have to de-crease the start up factor by as much as 25 to 30% toget it where you want it. You can then make some fineradjustments once you get it close to what you desire.Pushing the change display button again will move youto the next screen which displays the minimum pumpspeed. The minimum pump speed should be set to 0using the application rate switch. When the minimumpump speed has been set, depress the reset gallons but-ton to move to the next screen.

Always refer to the truck chassis owner’s manualfor chassis and engine maintenance information.

The following procedures apply to new or rebuiltunits.

1. Inspect the unit for damage that may have occurredduring transporting.

2. Check and tighten all fasteners, body tie-downbolts, pipe and circulating line connections, etc. thatmay have loosened in transit.

3. Check the fluid level in the hydraulic reservoir.The fluid must always be visible in the sight glass.

WARNING

To prevent becoming entangled in machineryremain clear of rotating drives.

Using the Etnyre Computator (See Fig. 1)1. To determine the proper speed and pump dis-

charge, use the Etnyre Computator. On the top scale,find the spray bar length to be used.

2. At the right end of the Computator, grasp the slidein the thumb recess and move the slide until the desiredapplication rate is directly below the spray bar length.

3. Below the desired speed, you will find the neces-sary pump discharge rate.

Let’s do a sample calculation for 12 feet of spraybar at an application rate of 0.3 gallons per sq yd. and atruck speed of 250 fpm. Move the slide to set the .3directly under the 12 ft. Now you can see that directlybelow the 250 fpm distributer speed is the required as-phalt pump rate of 100 gpm. The reverse side of thecomputator presents the information in metric units.

Preparing for Operation

Engaging Pump on PTO EquippedDistributors

Before getting into the cab, check to make sure thatthe front/rear pump control switch on the rear controlpanel is in the forward position.

Start the truck engine with the transmission in neu-tral and engage the PTO. On trucks with a manual trans-mission, depress the clutch and pull outward or upwardon the PTO control knob. Slowly let the clutch up, ifthe PTO fails to engage, depress the clutch pedal andpull up on the PTO handle until engagement occurs.Or, depress the electric air shift PTO switch if yourvehicle is so equipped. Increase the engine rpm to afast idle.

On trucks with an automatic transmission, push downon the foot brake pedal, move the gear selector to anyforward gear and pull upward or outward on the PTOcontrol knob. Or depress the electric air shift PTO switchif your vehicle is so equipped. When the PTO engages,move the gear selector to neutral.

If the PTO fails to engage, continue pulling on theknob while releasing the brake pedal slightly, allowingthe truck to inch forward until the PTO engages andthen move the gear selector back to neutral.

Ensure that the truck parking brake is engaged be-fore leaving the cab.

WARNING

To prevent an explosion or fire hazard: Donot heat the material beyond themanufacturer’s recommended temperature.

CAUTION

To prevent possible damage to equipmentfrom material setting up in hose or distributor,ensure that bitumen in supply tank is heatedsufficiently.

WARNING

To prevent possible burns: Use extremecaution when using a torch to heat the pump.Asphalt accumulated around the pump mayignite when heating the pump with a torch.

FoamingIf the distributor is to be filled with hot bitumen,

proceed very cautiously. If there is any moisture in thetank, or if an emulsion product was the last load, foam-ing or eruption may occur.

Dow-Corning DC-200 may be used to prevent foam-ing in Distributors, Transports, and Maintenance Units.

Mix the contents of one can (16 oz.) with one (1)gallon of diesel fuel or kerosene. Add one (1) oz. ofthis diluted mixture to each 1000 gallons of asphalt.The correct amount may be poured through the man-hole. This will assist in reducing foaming, particularlyif moisture is present or if an emulsified asphalt wasused in a previous load.

If foaming does not occur at the start of the fillingoperation, but you suspect that there may be moisturein the spray bar or circulating system, the filling opera-tion should be stopped when the tank is no more than25% full. The product should then be circulated throughthe spray bar at a rate of 80 to 100 GPM before con-tinuing the filling operation.

If foaming does occur, continue circulating until thefoaming stops, and then suck back the product in thespray bar back into the tank before filling the tank therest of the way.

Asphalt InstituteTo further increase awareness of the hazards associ-

ated with the operation of a bituminous distributor, andbefore beginning initial operation, the operator shouldalso receive instruction by an authorized Etnyre dealer,or Etnyre representative.

The Centennial Distributor is designed to handle anumber of different products, such as AC’s, cutbacks& emulsions.

Knowledge of these liquid asphalts is required forsafe operation of the distributor. It is critical to knowwhich product can be loaded after the previous prod-uct, and which products react with each other.

The Asphalt Institute is a source of asphalt handlingsafety information.

Tank CapacityThe Centennial Distributor is designed to pump and

spray a variety of asphalt products in an efficient anduser friendly manner with great accuracy. The Centen-nial Distributor utilizes a computer to sense the vehicle’sground speed and control the hydrostatically drivenasphalt pump to maintain the set application rate, re-gardless of variations in vehicle speed or spray bar widthin use.

For a complete description of each of the controlsand how to set up the machine, refer to the set sectionof this manual.

WARNING

To prevent possible personal injury: Do notload the vehicle beyond the GAWR orGVWR. The maximum load volume must becalculated based on material density

The Centennial Distributor tank has a built-in airspace, or expansion space, above the “Tank Full” level.This air space is designed to minimize the chance thatthe tank will overflow if the material in the tank ex-pands due to heating or foaming. This air space shouldnot be used to carry product. The “Tank Full” level isbased on the vehicle’s axle ratings, and, GVWR at amaterial density of 7.7 lbs/gallon. A lower “tank full”must be calculated if a product with a density greaterthan 7.7 lbs/gallon is to be loaded. The lower “tank full”is calculated by multiplying the original “tank full” by7.7 and dividing the result by the new heavier productdensity.

If you suspect there may be moisture or emulsion inthe tank, Dow-Corning DC-200 additive can be usedto reduce foaming if a product being pumped is at atemperature in excess of 200ºF. Additional DC-200 ad-ditive may be obtained from E. D. Etnyre & Co. oryour Etnyre dealer.

Mixing Dow-Corning DC-200 Anti FoamAgent

Mix the contents of one can (16 oz.) with one (1)gallon of diesel fuel or kerosene. Add one (1) ounce ofthis diluted mixture to each 1000 gallons of asphalt.The correct amount may be poured through the man-hole. This will assist in reducing foaming, particularly

if moisture is present or if an emulsified asphalt wasused in a previous load.

If you suspect that there may be moisture in the spraybar or circulating system, the filling operation shouldbe stopped when the tank is no more than 25% full.The product should then be circulated from the tankthrough the spray bar for a minimum of 2 minutes at arate of 80 to 110 GPM before continuing the fillingoperation. After circulating product in the spray bar,suck back the material from the bar and then return tothe loading configuration and continue loading.

If foaming does occur, continue circulating until thefoaming stops, and then suck back the product fromthe spray bar into the tank before continuing the load-ing operation.

Filling Through the Fill Line

WARNING

To prevent possible burns from foaming orviolent eruption, do not load tank withmaterial temperature over 200ºF if water orcondensation is present in tank, or ifemulsion was used in the previous load. Donot heat material over 200ºF if moisture oremulsion is present in tank.

See the section on foaming on the previous page.

Circulating Product in the Bar

WARNING

To prevent an explosion or fire hazard:Ensure that the burners are extinguishedbefore removing any material from the tankin any manner. Liquid petroleum (LP)burners can support a flame for severalminutes after the fuel supply is turned off.

1. Set all of the valve positions first.

Perform the procedure for circulating in the tank first.Then move the rotary actuator knob to the “Circulatein Bar” position. If your distributor is not equipped witha rotary actuator, at the rear of the distributor, place the4-way valve lever in the “Circulate in Bar” position.The circulate in tank procedure can be performed fromeither the cab or the rear control panel.

CAUTION

To prevent excessive pressure in the spraybar, the asphalt pump speed should notexceed 160 GPM while circulating in thespray bar.

Circulate product long enough to ensure removal ofall air from the bar and to heat the spray bar valvessufficiently. Material will circulate in the bar endswhether the wings are folded or extended.

Spraying OperationsA correct spray pattern cannot be obtained unless

the product is heated to its proper spraying tempera-ture. Cold product will not provide sharp spray edges,and will cause streaking. If heating of the product isrequired, refer to the section of this manual on “Heat-ing Product in Distributors” or your Operator’s Manualfor instruction on operation of your particular type ofburners.

The DC-2 computer automatically adjusts the asphaltpump speed to deliver the correct amount of asphaltfor the application rate, spray width and vehicle speed.The circulation rate in the bar when not spraying shouldbe set to 50% of the pump speed while spraying. Thiscirculation rate will allow the asphalt pump to reachthe desired speed quickly when spraying is started. Cir-culation rates higher than 50% will result in a heavierstart while rates below 50% will produce a lighter start.

WARNING

To prevent an explosion or fire hazard: Ensurethat the burners are extinguished beforeremoving any material from the tank in anymanner. Liquid petroleum (LP) burners cansupport a flame for several minutes after thefuel supply is turned off.

To prevent an explosion: Do not operate theburners when the vehicle is unattended,when the vehicle is in motion, or with thevehicle in a confined area.

To prevent an explosion or fire hazard: Whenthe burners go out, shut off the fuel supply toboth burners and allow the flues to ventilate forat least 3 minutes before re-lighting theburners.

To prevent an explosion or fire hazard: Do notheat the material beyond the manufacturer’srecommended temperature.

To prevent an explosion or fire hazard: Keepburning cigarettes or other sources ofcombustion away from manholes and overflowvents.

To prevent possible hand or facial burns:Always light the inside burner first. Do notreach across a lit burner to light or re-light theinside burner. Shut off the outside burnerbefore lighting the inside burner.

To prevent possible burns from materialoverflow: Allow sufficient space in the tank forexpansion of the material when heating

To prevent possible burns to operators orbystanders, or possible equipment damage, donot start any operation if any control settingsare unknown.

To prevent possible burns from leakingmaterial: Be sure all pipe, cap and hoseconnections are secure before opening valves.

WARNING

To prevent possible burns from hot asphaltspray: Do not stand, or allow anyone to stand,where accidental opening of a valve maycause contact with hot asphalt.

Spray bar nozzles have a limited flow range at whichoptimal performance will be achieved. Flow ratesgreater than this optimal range will cause excessivefogging. Rates that are too low will cause the fan tosag and cause heavy edges. Refer to the nozzle selec-tion chart in the operator’s manual to select the nozzlesappropriate for your conditions.

Adjusting the Spray Bar Nozzle AngleAdjust the nozzles to obtain an angle of approxi-

mately 30 degrees with the spraybar centerline. Everynozzle should be at the same angle. A nozzle adjust-ment wrench is supplied with each new unit.

Figure 7. Adjusting the Spray Bar Nozzles

Figure 8. Adjusting the Spray Bar Height.

Adjusting the Spray Bar HeightLower the spraybar and adjust the down stops so that

the nozzles are approximately 12” above the road, onthe main bar with both wings folded, when the tank isempty. At this height, the spray fans from the nozzleswill overlap to provide triple lap coverage of materialon the ground. This is the normal spraying height. Lowerthe wings and adjust them with the cylinder nuts to fol-low the crown of the road. The spray bar should be at anangle of 100 to 105 degrees with the surface of the roadwhen viewed across the road. This slight rearward tra-jectory compensates for the forward movement of thedistributor to evenly coat the front and back sides ofprojections on the road surface.

Spraying through the BarBefore spraying, place the valves in position for spray-

ing.

spraying, the truck speed does not have to remain con-stant to maintain the application rate accuracy. At higherspeeds, flow rates can increase beyond the nozzle flowrating. When this occurs, fogging will result and youshould slow down. At lower speeds, the flow rate maydecrease below the recommended nozzle flow rating.When this occurs, the fan droops causing incompleteoverlapping, heavy edges and streaking.

When the end of the shot is reached, turn the “SprayBar” switch “off” or down. The 4-way valve is auto-matically returned to the “Circulate in Bar” positionwhen the spray bar is turned off.

During the periods between shots, material shouldbe circulated in the spray bar to keep the bar warm andprevent material set up in the bar. However, materialshould not be circulated in the bar when travelling fromlocation to location. If you want to shut the distributordown at the end of the day or between shots, you mustsuck back the system. Refer to the suck back portion ofthis manual for instructions.

CAUTION

Do not run the pump above rated capacity of400 GPM. Damage to equipment may occur.

Setting the Digital Memory PresetsSetting the digital memory presets is not required to

spray. The memory buttons offer the operator a conve-

application rate on the digital display. The ApplicationRate may be changed while spraying simply by usingthe “Application Rate” toggle switch. You may returnto the original application rate at any time by eitherusing the toggle switch or depressing the proper presetmemory button. Engage the PTO if the distributor hasa PTO driven hydrostatic pump. Before moving the bar,circulate some hot material through the bar. This al-lows the bar to warm up and also extends the life of thebar seals and o-rings.

Prior to setting the “Rotary Actuator” to the “Circu-late in Bar” position, decrease the asphalt pump flowrate to a maximum of 160 GPM, to avoid excessivepressure in the spray bar when you are not spraying. Ifyour distributor is not equipped with a rotary actuator,at the rear of the distributor, place the 4-way valve le-ver in the “Circulate in Bar” position. The circulationrate in the bar when not spraying, should be set to 50%of the spray rate, but not greater than 160 gpm. Whenthe desired application rate is set in the computer, placethe “Rotary Actuator” in the “Circulate in Bar” posi-tion and allow the material to circulate in the bar for afew minutes to warm up the bar, valves and nozzles.Lower the spray bar and continue to heat to bring thespray bar up to operating temperature.

Put the truck transmission and rear axle in the propersettings for the shot.

Start the distributor moving in the pre selected gear.

At the start line of the shot, move the “Spray Bar”switch to the “On” position. While the distributor is

Turn the “Rotary Actuator” to the “Load/Suckback”position. If your distributor is not equipped with a ro-tary actuator, at the rear of the distributor, place the 4-way valve lever in the “Circulate in Tank” position.

Ensure that the suction valve is closed.

Open the self-flushing valve and run the pump atapproximately 100 GPM.

After 2 minutes, close the self flush valve.

Normally the suckback procedure will remove suf-ficient material from the circulating system to negatethe need for draining the circulating system and spraybar before proceeding with the wash out operation. Theflushing operation requires only 3 quarts of flushingsolvent. This small amount is not sufficient to fill thelines to the tank, thus preventing solvent from beingforced into the tank.

A common practice following completion of theflushing procedure and subsequent shutdown is to pour1 to 2 quarts of solvent into the fill line. This softens ordissolves the residual asphalt in the pump. Allow thesesolvents to remain in the system until the next use.

If unit has electric washdown option, open flushvalve and turn on electric pump for 2 minutes. Thiswill pump 2 quarts of diesel fuel on top of the asphaltpump.

LPG Supply Tank RequirementsUse only liquid withdrawal type supply tanks for your

LPG burners.

Two types of LPG supply tanks are available: tanksfor liquid type burners and tanks for vapor type burn-ers. The LPG burners on your Etnyre distributor re-quire a supply tank for liquid type burners. Liquid typeburners will operate from a vapor withdrawal tank,however the amount of heat delivered will be dramati-cally reduced, and the life of the burner will be short-ened.

There are three different types of LPG burners:manual control burners, burners with outfire control,and burners with automatic ignition and temperaturelimiting control.

Manual Control BurnersThere are four valves associated with operation of

the manual control burners: one at the supply tank, andthree in the burner piping.

The two smaller valves (one at each burner) arebleeder type valves with a small hole drilled throughthe valve case. Propane liquid is supplied to the bleedervalve directly from the supply tank shutoff valve. Be-cause of the bleeder hole in this valve, it is NOT pos-sible to shut off all of the fuel to the lower burner byshutting the main valve at the burners. The main burnervalve will only shut off the upper burner. The lowerburner must be shut off using the supply tank valve.

WARNING

Always shut off burners using the mainshutoff valve on the supply tank

The large valve located in the fuel line to the outsideor upper burner is a positive cut off valve that allowsall fuel to be cut off to the bleeder valve on the outsideburner only.

Burner OperationBe sure that the main supply valve and the main

burner valves are fully closed and the bleeder valvesare turned fully clockwise before starting.

Open the dampers in the flue exhaust stacks.

Open the valve at the supply tank and immediatelylight the inside burner. As soon as the burner lights,open the bleeder valve. No preheating is necessary.

Heating Asphalt with Liquid PropaneGas (LPG) Burners

IMPORTANT

Circulating the asphalt in the tank while heatingis recommended for faster heating andreduced carbon formation on the flues. Onlywhen the asphalt pump is “Frozen” is itacceptable to operate the burners withoutcirculating asphalt in the tank. However, if theasphalt pump is frozen, carefully apply heat tothe pump and start circulating the material assoon as possible.

WARNING

Residual fuel in LPG burners will support a flamefor several minutes after the fuel flow has beenshut off. After using LPG burners, confirm that allflame has been extinguished before attemptingany operation that could release flammablevapors.

Failure to ensure that the flame is completelyextinguished could result in an explosion or firethat can cause injury or death.

To prevent an explosion or fire hazard: Positionunit broadside to wind whenever possible toprevent volatile fumes from drifting towardburners

To prevent an explosion or fire hazard: FluesMUST be covered by a minimum of 6 inches ofmaterial when the burners are in operation.

To prevent an explosion or fire hazard: Do notremove material from tank in any manner whenthe burners are in operation.

To prevent an explosion or fire hazard: Do notdrive unit when burners are operating.

To prevent an explosion or fire hazard: Do notoperate burners if tank is damaged or leaking.

To prevent an explosion or fire hazard: Whenburners go out, allow flues to ventilate for severalminutes before relighting burners.

To prevent an explosion or fire hazard: Do notheat material beyond the manufacturersrecommended temperature.

To prevent foaming or violent eruption, do notheat material over 200ºF if moisture is present intank.

To prevent possible burns from material overflow,allow sufficient space in tank for expansion ofmaterial when heating.

35

IMPORTANT

When the main fuel valve is opened at thebottle or tank, there is an immediate trickle ofgas passing through the inside burnerbleeder valve. Light the burner immediately

Check the fuel pressure at the pressure regulator. Toomuch pressure for a small asphalt tank will waste fuel.Too little pressure will increase heating time. Some ex-perimentation with the pressure will allow you to de-termine the most efficient fuel pressure to use. The fol-lowing is a good rule of thumb.

1000-1250 gallon tank- 15 psi

1500-1750 gallon tank- 20 psi

2000-2250 gallon tank- 25 psi

2250-2500 gallon tank- 30 psi

2750 gallon and larger- 40 psi

If necessary, adjust the flame with the bleeder valveat the burner.

When the LPG burners are operating, the outside ofthe fuel line up to the first coil of the burner shouldfrost over. If no frost forms it is an indication that theburners are operating on vapor instead of liquid. Thiscondition must be corrected immediately to preventdamage to the burners.

If after the lines frost over, the flame starts to diedown and the frost melts off the fuel line, it is likelythat there is moisture in the fuel supply tank. Moisturein the fuel can form ice crystals that stop the fuel flow.Your local LPG supplier can add an anti-icing agent toprevent burner icing.

IMPORTANT

It is recommended that two persons beinvolved in lighting the first burner. When themain fuel valve is opened at the tank, thereis an immediate trickle of gas passingthrough the inside burner valve. The longerthe gas is allowed to collect in the flue, themore likely there will be a flashback whenthe burner is ignited. Having one person lightthe burner while the other opens the mainsupply valve will reduce the likelihood of aflashback.

WARNING

To prevent possible burns, always use atorch to light the burners. Never attempt tolight the burners with a match or pocketlighter.

WARNING

A fully charged dry chemical type fireextinguisher must be within easy reachwhenever the burners are operating or thereis an open flame near the distributor.Minimum dry chemical capacity of the fireextinguisher should be 10 pounds.

Figure 16. Manual Control Burner System

36

Burners With Outfire ControlsEquipment Design

The burner and the burner control valves are identi-cal to the manual operated burner system. However,burners with outfire controls are equipped with an out-fire control box. The outfire controls consist of two ther-mocouples, a push button start switch, an electric fuelsolenoid valve, a pressure regulator and a pressure gage.

The heat sensing thermocouples are positioned ineach burner. If either burner loses its flame, the ther-mocouple senses the drop in temperature, and deacti-vates the fuel solenoid, and the fuel to both burners isshut off.

The only operational differences between the manualburners and burners with the optional outfire controlsis the start up and shut down procedures. Unlike themanual burners, when the burners are equipped withoutfire controls, no fuel flows to the burners when themain solenoid shutoff valve is closed.

Burner Operation with Outfire ControlsTurn on the Master Power switches.

Open the dampers in the exhaust stacks.

Ensure that the main burner control valve is closedand that the bleeder valves for both burners are turnedfully clockwise.

IMPORTANT

It is recommended that two persons beinvolved in lighting the burners. One personshould hold the torch while the other personopens the valves and holds the pushbuttonin.

Open the main fuel supply valve at the tank.

No fuel will be flowing at this point.

As soon as the low fire is established at the innerburner, open the positive shutoff valve to the outsideburner and light the outside burner on low fire.

After 30 to 40 seconds, release the pushbutton andobserve the pressure gage. If the pressure starts to droprapidly, depress the pushbutton and hold it in for an-other 30 seconds. It may require a slight increase infuel to the outside burner to adequately heat the ther-mocouple. Once both of the thermocouples are heatedthe pushbutton can be released.

IMPORTANT

If there is at least 6” of material covering theentire length of the upper flue, the secondburner can be lit.

WARNING

To prevent possible burns, always use atorch to light the burners. Never attempt tolight the burners with a match or pocketlighter.

To ignite the second burner ensure that the bleedervalve on the burner is turned fully clockwise. Positiona lit torch at the burner nozzle and open up the positiveshutoff valve in the line to the burner. As soon as thelow fire is established, the bleeder valve can be opened.

Never leave operating burners unattended.

WARNING

When heating, temperatures within the tankcan vary. Shut the burners off when thethermometer reaches a reading 10ºF. lowerthan the desired temperature. Continue tocirculate & monitor temperature untiltemperature stabilizes. Add remaining heatby operating burners for short periods,monitoring stabilized temperature after eachperiod.

WARNING

Calibration of thermometers should beverified to be within + 2% of full scalereading annually.

Certification can be accomplished by aqualified laboratory or by comparingstabilized dial readings to the pencilthermometer reading. Replace anythermometer that does not meet the +2%accuracy requirement.

When the desired temperature is reached, close themain fuel supply valve, at the lpg tank, first. Allowthe burners to operate at full capacity until the fuel inthe line from the tank burns out, then close both bleedervalves and the positive shutoff valve for the outsideburner.

Close the exhaust stack dampers to prevent heat loss.

37

IMPORTANT

In order to activate the thermocouples, bothburners must be lit on low flame even if onlyone burner will be used for heating. Placethe ignition torch at the inside burner nozzleand depress the pushbutton in the outfirecontrol box. Continue to hold the pushbuttonin until both burners are lit.

If both burners are to be used for heating, you cannow open both bleeder valves. If only the inside burneris to be used for heating, open the bleeder valve on theinside burner and allow the outside burner to remainburning on low flame so the thermocouple will beheated. Remember, if either burner flame goes out, theoutfire control will shut the solenoid valve cutting thefuel off to both burners.

WARNING

A fully charged dry chemical type fireextinguisher must be within easy reachwhenever the burners are operating or thereis an open flame near the distributor.Minimum dry chemical capacity of the fireextinguisher should be 10 pounds.

When the desired product temperature is reached:

Close the main fuel supply valve at the tank.

After all the fuel is burned and there is no flame ateither burner, turn both bleeder valves fully clockwiseand close the positive cut off valve at the burners.

Close the exhaust stack dampers to prevent heat loss.

Figure 18 Burner System with Auto Ignition & Temperature Control

Burners with Automatic Ignition andTemperature Limiting Control

Equipment Description

The temperature limiting control box contains thetemperature limiting control components as well as theautomatic ignition circuitry.

The automatic ignition circuit consists of two 12Vcoils, two spark plugs, a pair of thermocouples, (one ateach burner), and a momentary pushbutton switch. The12V coils send high voltage to the spark plugs thatcauses sparks to arc intermittently at each pilot burnerwhenever there is fuel pressure in the line from the mainsupply tank. The thermocouples provide a signal thatindicates when there is a flame at the pilot burners. Themomentary pushbutton switch on the control box is usedto fire the main burners once the pilot burners have ig-nited and the thermocouples have been heated suffi-ciently.

The temperature limiting control circuit consists ofa temperature probe in the distributor tank that sensesthe asphalt temperature, a thermostatic switch in thecontrol box and a temperature adjustment dial on theface of the control box. When the temperature of theasphalt in the distributor is heated to the temperatureselected with the temperature adjustment dial, the ther-mostatic switch shuts down the burners.

Burner Operation with Auto Ignition &Temp Control

Open the dampers on the exhaust stacks

Ensure that all burner valves are closed.

With this type of control, the inside or lower burnermay be operated without opening the positive shut offvalve to the outside burner. If both burners are to beused, the positive shutoff valve should be opened.

Open the main fuel valve at the supply tank. Thespark plugs will begin to arc and will ignite the pilotburners.

Set the thermostat to the desired temperature.

Allow the pilot burners to heat the thermocoupleprobes for at least 2 minutes. When the pilot burnershave heated the thermocouples sufficiently the sparkerwill stop. Press the cycle button to fire the main burn-ers. The bleeder valves may then be opened.

On new or rebuilt units, monitor the product ther-mometer to make certain that the burners shut downwhen the desired temperature is reached. (as set on thetemperature adjustment dial. If the burners do not shutdown at the correct temperature, refer to “Calibratingthe Thermostat”.

Once the burner shuts off automatically, it will notrestart until the cycle button is again depressed.

39

Figure 19. Electric Burner System

To shut the system down: Close the main fuel sup-ply valve at the tank.

Increase the thermostat setting 50 to 75ºF higherand push the start button. This will bring on the mainburners and quickly burn off all of the fuel in the linebetween the tank and the control box. The pilot burn-ers may continue to burn for a short time after themain burners cut off. Do not draw material from thetank as long as there is a flame present.

Close the exhaust stack dampers.

Electric Driven Burner OperationOpen the dampers in the exhaust stacks.

To light the burner, turn on the “Lower BurnerPower” switch.

If upper burner operation is desired, turn on the “Up-per Burner Power” switch.

SERVICING THE ETNYRE P-15 PUMP

6. Next, measure the case bore vertically at a point2.8 inches from each side. The vertical measurementmust not exceed 5.660 inches. If any bore measure-ments exceed these limits, the entire pump must be re-placed.

7. If inspection indicates the pump case is accept-able, measure the outside diameter of the impeller gears.Measure the impeller gears from tooth point to toothpoint on teeth directly opposite each other. The mini-mum outside diameter of the gears should be 5.635inches. The minimum length of the gears should be3.628 inches.

8. If any impeller gear is undersize, the entire four-gear set must be replaced.

9. End plate gasket thickness should be 0.014 - 0.016inches.

10. Divider plate thickness should be 0.127 - 0.128inches.

Impeller Installation And PumpAssembly

Each impeller gear set uses a series of dots on thegear faces to indicate position of the gears within thepump. Refer to Figure 24 for proper positioning of thegears. The dots must face away from the divider plate(towards the ends of the pump). Install the impellers innumerical order.

Vacuum Check1. Flush pump with 3 quarts of diesel fuel through

fill line.

2. Set controls for filling operation.

3. Install vacuum gauge in fill line cap.

4. Operate pump at 140 GPM on pump tachometer.A vacuum reading of less than 5Hg. (inches of mer-cury) after 2 minutes of operation indicates a vacuumleak or a worn pump.

Pump Disassembly And Inspection1. Remove 20 capscrews from perimeter of pump

end plate (see Figure 24).

2. Install two capscrews in the threaded holed nearthe outer edge of the end plate at approximately the 5o’clock and 11 o’clock positions. Tighten thecapscrews evenly to force the endplate away from thepump body.

3. Remove the endplate, impeller shafts and impel-lers (gears) as an assembly.

4. Clean the interior of the pump case. Slide yourfingers across the interior surfaces of the case. If anarrow raised area can be felt midway between the frontand the rear of the case, the entire pump should bereplaced.

5. If there is no raised area, measure the bore of thecase at its widest point horizontally (side-to-side). Thismeasurement must not exceed 9.910 inches.

Heating TerminologyFlash Point (Open Cup)

The temperature at which a flammable liquid in anopen container emits vapor that will flash when ex-posed to a direct flame. This temperature is lower thanrequired for the liquid mass to ignite.

Closed Flash PointThe temperature at which a flammable liquid in a

closed container emits a vapor that will flash when ex-posed to a direct flame. This temperature is lower than

required for the liquid mass to ignite. The closed flashpoint is generally 30° (F) lower than the open cup flashpoint.

Fire PointThe temperature at which a flammable liquid emits

a vapor at a rate that will continue to burn after it hasflashed.

Ignition Temperature(Kindling Temperature)

The lowest temperature at which a combustiblematerial will continue to burn once ignited.

ConvectionHeat transfer by a flow of a liquid or gas over a solid

material. Example: Flues in asphalt tank are heatedfrom hot gases passing through them, or, heat transfercoils in tank are heated from steam or hot oil passingthrough them.

ConductionHeat transfer through a solid mass by direct molecu-

HYDRAULIC FLUID REQUIREMENTS

General InformationThe ability of a hydrostatic transmission to maintain

desired performance for the expected life depends onthe quality of fluid being circulated in the units. Fluidquality can be measured in three general categories:lubricity, contaminants, and temperature. Obtainingsatisfactory values in these three areas depends on thefluid and the circuit in which it is used.

Etnyre field service experience indicates that mosttransmission failures result from a breakdown of fluidquality. Primary causes are solid particle contamina-tion and overheating. Water or oil in the fluids are alsosignificant contributors. These problems are usually theresult of poor maintenance. Sometimes fluid selectioncan lessen the impact of unusual environmental fac-tors.

Hydraulic fluid requirementsThe catalog ratings and performance data are based

on operating with good quality petroleum based fluids.Premium hydraulic fluids containing high quality rust,oxidation and foam inhibitors are required. These in-clude premium turbine oils, API CD engine oils perSAE J183, M2C33F or G automatic transmission fluid(Type F), power shift transmission fluids meeting Alli-son C-3 or Caterpillar TO-2, and certain specialty agri-cultural tractor fluids.

Although fluids containing anti-wear additives arenot necessary for satisfactory performance, when used,the fluids must possess good thermal and hydrolyticstability to prevent wear, erosion and corrosion of theinternal components.

Where water contamination is likely due to conden-sation, operation in a damp environment or frequentsplashing, a fluid with outstanding hydrolytic stabilityis recommended. Consult the Etnyre Service Depart-ment for recommendations for these fluids. Avoidingthe use of Dexron II transmission fluids which do notmeet Allison C-3 specification is recommended.

Viscosity & Temperature RequirementsThe fluid must have sufficient viscosity to maintain

an oil film at the bearing surfaces. This depends on fluidselection and on operating temperature. Recommendedviscosity for best life and efficiency, and minimum forintermittent and continuous operation is listed below.

Fluid Viscosity Limits

For Petroleum Based Fluids

Maximum Continuous SUS (cSt) 500 (110)

Optimum Viscosity SUS (cSt) 70 (13)

Minimum Continuous SUS (cSt) 55 (9.0)

Minimum Intermittent SUS (cSt) 47 (6.4)

Viscosity index improved (multi-viscosity) fluidsmay noticeably shear down in service when used inhydrostatic transmissions. This will lower the operat-ing viscosity below the originally specified value. Thelowest expected viscosity must be used when selectingfluids. Consult your fluid supplier for details on vis-cosity sheardown.

Fluid temperature affects the viscosity of the fluidand resulting lubricity and film thickness. High tem-peratures can also limit seal life, as most nonmetallicseals are adversely affected by use at elevated tempera-tures. Also, fluids may break down or oxidize at hightemperatures, reducing their lubricity and the resultinglife of the unit. Cavitation is more likely at high tem-perature. Recommended limits for operating tempera-tures are tabulated below.

Fluid Temperature Limits

For Petroleum Based Fluids

Continuous Limit 180ºF.

Intermittent Limit 220ºF.

These temperature limits apply at the hottest pointin the transmission, which is normally the motor casedrain.

Heat problems sometimes occur because of prob-lems with one of the circuit components. A partiallystuck relief valve will heat up the oil rapidly. Circuitcomponents that have developed high internal leakagerates will contribute to heat generation.

Contamination LevelsClean fluid implies the absence of impurities such

as solid particles, water and air. Contamination controlincludes proper design, installation, and maintenanceof hydraulic components.

The reservoir is designed to limit entry of contami-nation during servicing and operation. A sealed reser-voir with a low pressure relief valve reduces the intro-

duction of contaminants while maintaining inlet andcase drain pressures below the maximum recom-mended.

The purpose of the filter in a system is to clean theoil at initial start up and to maintain acceptable levelsof particle contaminants as they are ingested or gener-ated during operation of the system. Filtration is a mat-ter of controlling the particle sizes and their respectivequantities to appropriate levels so as to avoid degrada-tion of the system components and thereby assure thedesired life.

Fluid contaminant profile requirements for Etnyrehydraulic units have been determined empirically basedon measuring fluid quality in successful application,and in laboratory tests designed to evaluate hydraulicunit contaminant sensitivity. General contaminant lev-els have been developed based on this experience andare shown in Figure 25.

Acceptable contamination levels at machine start upfor the system loop should be equal to or better thanCurve D. The machine may be exercised to 500 psi butshould not be worked (pressure over 500 psi) until theoil cleanliness meets or exceeds Curve C.

The machine should clean up during a relatively shortperiod of normal operation to meet the oil cleanlinesslevel of Curve A or Curve B. A system that meets CurveA will provide the user with a longer trouble-free oper-ating life than one that meets Curve B. The Curve Acleanliness level should be met in systems exceedingthe continuous pressure limit for 1000 hours/years ma-chine use.

Some control valves may require better contamina-tion limits than specified in Figure 25. Controls withsmall area screens or low force level values may besusceptible to malfunction from contamination.

The contamination sensitivity of components gen-erally increases with higher pressure, temperature orspeed. A better fluid contaminant profile may be re-quired for systems which operate near the extremes oftheir ratings. Short life or infrequent operation require-ments may increase allowable contaminants.

The selection of a filter depends on a number of fac-tors including the contaminant ingression rate, the gen-eration of contaminants in the system, the required fluidcleanliness, and the desired maintenance interval. Fil-ters are selected to meet the above requirements usingrating parameters of efficiency and capacity.

Filter efficiency may be measured with a Beta ratio.for simple closed circuit transmissions with controlledreservoir ingression, a filter with a Beta ratio of 1.5 to2 has been found to be satisfactory. For some open cir-

cuit systems, and closed systems with cylinders beingsupplied from the same reservoir, a considerably higherfilter efficiency is recommended. This applies to sys-tems with gears or clutches using a common reservoir.For these systems, Beta ratios of 10 or 20 are typicallyrequired.

The filter capacity required depends on the amountof contaminants ingressed and retained in the filter and

the desired maintenance interval. As a rough guide, acapacity in grams equal to twice the charge flow in GPMhas been found to be satisfactory for our systems.

Since each system is unique, the filtration require-ments for that system will be unique and must be deter-mined by test in each case. It is essential that monitor-ing be the final criteria for judging the adequacy of thefiltration system.
