Ventilation and Combustion AirRequirements - Direct Vent

A Direct Vent appliance utilizes uncontaminat-ed outdoor air (piped directly to the appliance)for combustion)

For Direct Vent installations, involving only thePRESTIGE Excellence, in which the minimumservice clearances are maintained as listed onpage 4, no ventilation openings are required.

For Direct Vent, zero clearance installationsinvolving only the PRESTIGE Excellence, thespace / enclosure must provide two openingsfor ventilation. The openings must be sized toprovide 1 square inch of free area per 1,000BTUH of boiler input. The openings shall beplaced 12 inches from the top of the space and12 inches from the floor of the space.

For installations in which the PRESTIGEExcellence shares the space with air movers(exhaust fan, clothes dryers, fireplaces, etc.)and other combustion equipment (gas or oil)the space must be provided with adequate airopenings to provide ventilation and combus-tion air to the equipment. To properly size theventilation / combustion air openings, theinstaller must comply with the National FuelGas Code NFPA 54, ANSI Z223.1 for installa-tions in the U.S or CSA B149.1 and B149.2 forinstallations in Canada.

The space must be provided with venti-lation / combustion air openings proper-ly sized for all make-up air requirements(exhaust fans, clothes dryers, fireplaces,etc.) and the total input of all applianceslocated in the same space as the PRES-TIGE Excellence, excluding the input ofa Direct Vent PRESTIGE Excellencewhich uses combustion air directly fromthe outside, thus additional free area forthe openings is not required. Failure toprovide or properly size the openingscould result in severe personal injury,death or substantial property damage.

Ventilation and Combustion AirRequirements - Category IV

A Category IV appliance utilizes uncontami-nated indoor or outdoor air (surrounding theappliance) for combustion.

In order to reduce the potential risksassociated with indoor contaminates(listed on page 5), flammable vapors andtight housing construction (little or noinfiltration air), it is recommended topipe uncontaminated combustion airdirectly from the outdoors to the appli-ance. This practice also promotes highersystem efficiency by reducing heatedindoor air from being exhausted fromthe house and replaced by cold infiltra-tion air into the house.

For installations in which the PRESTIGEExcellence shares the space with air movers(exhaust fan, clothes dryers, fireplaces, etc.) andother combustion equipment (gas or oil) thespace must be provided with adequate air open-ings to provide ventilation and combustion air tothe equipment. To properly size the ventilation/ combustion air openings, the installer mustcomply with the National Fuel Gas Code NFPA54, ANSI Z223.1 for installations in the U.S orCSA B149.1 and B149.2 for installations inCanada, as referenced in this section of the man-ual and titled Methods of AccessingCombustion Air into a Space.

The space must be provided with venti-lation / combustion air openings proper-ly sized for all make-up air requirements(exhaust fans, clothes dryers, fireplaces,etc.) and the total input of all appliances,including the PRESTIGE Excellencewhen located in the same space as thePRESTIGE Excellence.

SECTION IV - Boiler Piping

General Piping Requirements

- All plumbing must meet or exceed all local,state and national plumbing codes.

- Support all piping using hangers. DO NOTsupport piping by the unit or its components.

- Use isolation valves to isolate system com-ponents.

- Install unions for easy removal of thePRESTIGE Excellence from the systempiping.

• If plastic pipe is used for boiler water pip-ing, it must have a maximum oxygen diffu-sion rate of 0.1 mg/liter-day for boiler andwater heater protection.

Use a two wrench method when tighten-ing piping onto the boiler connections.Use one wrench to prevent the boilerpiping from turning / twisting. Failureto support the boiler piping and connec-tions in this manner could cause damageto the boiler and its components.

Pressure Relief Valve

1. The PRESTIGE Excellence is suppliedwith a 30 psi pressure relief valve and mustbe piped using the PRV connection asshown in Fig. 5 page 15.

2. To avoid potential water damage to the sur-rounding area or potential scalding hazarddue to the operation of the relief valve, thedischarge piping:

- Must be connected to the discharge out-let of the relief valve and directed to asafe place of disposal.

- Length should be as short and direct aspossible. The size of the discharge lineshould not be reduced, maintain thesame size as the outlet of the relief valve.

- Should be directed downward towardsthe floor at all times. The piping shouldterminate at least 6 inches above anydrain connection to allow clear visibili-ty of the discharge.

- Should terminate with a plain end, notwith a threaded end. The material ofthe piping should have a serviceabletemperature rating of 250ºF or greater.

- Should not be subject to conditionswhere freezing could occur.

- Should not contain any shut-off valvesor obstructions. No shut-off valveshould be piped between the boiler andrelief valve.

Failure to comply with the guidelines oninstalling the pressure relief valve and dis-charge piping can result in personal injury,death or substantial property damage.

Low Water Cutoff Device

- The PRESTIGE Excellence is equipped witha factory installed pressure switch type LowWater Cut Off device.

- The minimum operating system pressureallowable with this device is 10 psig.

- Check local codes if a Low Water CutoffDevice is required. If so, determine if thisdevice meets the requirements of the localcodes.

The PRESTIGE Excellence control sys-tem also uses the sensing of the systemwater temperatures entering and exitingthe heat exchanger to provide protectionagainst low water conditions Wherelocal codes and jurisdiction do notaccept a pressure device for low waterprotection, the jurisdictions may acceptthese PRESTIGE Excellence integralcontrol functions as a means of provid-ing low water protection.

Additional Limit Control

If a separate LWCO device is required by cer-tain local jurisdictions or when the boiler isinstalled above the system piping, the follow-ing guidelines must be followed:

- The LWCO device must be designedfor water installations, electrode probe-type is recommended.

- The LWCO device must be installed ina tee connection on the boiler supplypiping above the boiler.

- Wiring of the LWCO device to the PRES-TIGE Excellence is done directly onto the24V terminal strip, reference Fig. 20 page29 for available terminals for an externallimit (manual or auto reset).

If the installation is to comply with ASME orCanadian requirements, an additional hightemperature limit may be needed. Consultlocal code requirements to determine compli-ance. The limit should be installed as follows:

- Install the limit in the boiler supply pip-ing between the boiler and any isolationvalve.

- Maximum set point for the limit is194ºF.

- For wiring of the limit reference Fig. 20,page 29, using the external limit/manualreset terminals on the 24V terminal strip.This will provide a "hard" lockoutrequiring a manual reset of the control.

Backflow Preventer

- Use a backflow preventer valve in themake-up water supply to the unit asrequired by local codes.

Boiler System Piping Applications

It is recommended on all piping applica-tions to utilize a primary/secondary pip-ing arrangement as a means to providefreeze protection of the boiler, which is anintegral function of the boiler control.Maintain the minimum boiler flow rate,see Graph 2 on page 70. For other pipingarrangements, consult the EngineeringDepartment at Triangle Tube or consultother approved/recognized designarrangement.

On piping applications utilizing a singlezone or other recognized piping designarrangements, it is recommended that theinstaller uses flow/check valves withweighted seats at or near the appliance toprevent gravity circulation.

Expansion Tank and Makeup Water

Ensure the expansion tank is properly sized forthe boiler volume (5 gallons [19 L]) and thesystem volume and temperature.

Undersized expansion tanks will causesystem water to be lost through the pres-sure relief valve and cause additionalmakeup water to be added to the system.Eventual boiler heat exchanger failurecan result due to this excessive makeupwater addition.

CAUTION

BEST PRACTICE

BEST PRACTICE

16

The expansion tank must be located as shownin the piping diagrams on pages 19 through 21or as per recognized design methods. Refer tothe expansion tank manufacturer instructionsfor additional installation details.

Connect the expansion tank to an air separatoronly if the air separator is located on the suc-tion side (inlet) of the system circulator.Always locate and install the system fill con-nection at the same location as the expansiontank connection to the system.

Diaphragm Expansion Tank

Always install an automatic air vent on the topof the air separator to remove residual air fromthe system.

Closed-Type Expansion Tank

It is recommended to pitch any horizontal pip-ing upwards toward the expansion tank 1 inchper 5 feet of piping. Use 3/4” piping for theexpansion tank to allow air within the systemto rise.

DO NOT install automatic air vents on aclosed-type expansion tank system. Airmust remain in the system and bereturned to the expansion tank to pro-vide an air cushion. An automatic airvent would cause air to be vented fromthe system resulting in a water-loggedexpansion tank.

Circulator

The PRESTIGE Excellence is supplied with aboiler circulator that provides circulation forspace (CH) heating and domestic (DHW) hotwater production. See Graph 2 on page 70 forpressure drop and minimum flow rate throughthe boiler.

Sizing Primary Piping

See Fig. 9 through 13, pages 19 - 21, for rec-ommended piping arrangements based on vari-ous applications.

Size the piping and system componentsrequired in the space heating system, using rec-ognized design methods.

System Piping - Zone Circulators

Connect the PRESTIGE Excellence to the sys-tem piping as shown in Fig. 9 page 19 whenzoning with zone circulators.

The installer must provide a separate circulatorfor each zone of space heating.

To ensure adequate flow rate throughthe PRESTIGE Excellence, maintain aminimum 1 inch diameter on the systempiping connecting to the boiler.

System Piping - Zone Valves

Connect the PRESTIGE Excellence to the sys-tem piping as shown in Fig. 10 page 19 whenzoning with zone valves. The primary / sec-ondary piping ensures that the boiler loop hassufficient flow.


NOTICE

NOTICE

CAUTION

Boiler Piping

17

System Piping - Through Boiler

In applications in which primary/secondarypiping is not utilized and the system is zonedwith zone valves a circulator could pumpthrough the boiler and system directly. Whenpumping through with more than one zone, apressure differential bypass valve is required toavoid dead heading the pump through the postpump feature of the control. Consult Fig. 11and 12 page 20 for piping diagrams and Graph2 on page 70 for proper circulator sizing.

System Piping - Radiant Heating

The heat exchanger design of the PRESTIGEExcellence allows operation in a condensingmode. This feature requires no regulation ofthe return water temperature back to the boilerin radiant heating applications.

The boiler water supply temperature can bemaintained by the PRESTIGE Excellence,eliminating the need for a mix system toachieve the desired temperature.

The installer may consider adding a high tem-perature limit on the system piping to ensurethat the primary supply temperature does notexceed the maximum allowable temperaturefor the radiant tubing.

The addition of the high temperaturelimit is important when the PRESTIGEExcellence has completed a DHW mode,which requires a high primary supplywater temperature.

Due to the construction of the waterheater, do not install the PRESTIGEExcellence if the boiler piping containsnon-oxygen barrier tubing if the boilerpiping is considered an “open system”.Exposing the outer tank of the PRES-TIGE Excellence water heater to oxygencontamination will lead to prematuretank failure and denial of the warranty.

Size the system piping and circulator to providethe flow needed for the radiant system.


System Piping - Special Application

If the boiler is used in conjunction with achilled water/medium system, the boiler andchiller must be piped in parallel. Installflow/check valves to prevent the chilled medi-um from entering into the boiler.

If the boiler is used to supply hot water to theheating coils of an air handler where they maybe exposed to chilled air circulation, installflow/check valves or other automatic meansto prevent gravity circulation of the boilerwater during cooling cycles.

System Piping - Multiple Units Installation

It is recommended to use a balanced manifoldsystem as the primary / secondary connectionto the space heating piping.

Maintain a minimum of 6 inches of clearancebetween units to allow for servicing.

For the space heating piping refer to the appli-cations mentioned in this manual or use recog-nized design methods.

SECTION IX - Start-Up Preparation

Check Boiler System Water Chemistry

Do not use petroleum-base cleaning orsealing compounds in the boiler system.Damage to seals and gaskets in the sys-tem components could occur, resulting insubstantial property damage.

System water including additives must bepractically non-toxic, having a toxicityrating or Class of 1, as listed in ClinicalToxicology of Commercial Products.

Water pH Level 6.0 to 8.0

Maintain the boiler water pH between 6.0 and8.0. Check using litmus paper or contact a watertreatment company for a chemical analysis.

If the pH does not meet this requirement, donot operate the PRESTIGE Excellence or leavethe unit filled until the condition is corrected.

Water Hardness Less Than 7 Grains

For areas with unusually hard water (hardnessabove 7 grains) consult a water treatmentcompany.

Chlorinated Water

Do not use the PRESTIGE Excellence to heata swimming pool or spa directly.

Maintain the chlorine level of the water at lev-els considered safe for drinking.

Flush System to Remove Sediment

The installer must flush the boiler system toremove any sediment to allow proper operationof the PRESTIGE Excellence .

Flush the systems until the water runs cleanand is free of sediment.

For boiler zoned systems, each zone should beflushed through a purge valve. Purge valvesand isolation valves should be installed on eachzone to allow proper flushing of the system.

Check and Test Antifreeze

For boiler systems containing antifreeze solu-tions, follow the antifreeze manufacturer’sinstructions in verifying the inhibitor level andto ensure the fluid characteristics are withinspecification requirements.

Due to the degradation of inhibitors over time,antifreeze fluids must be periodically replaced.Refer to the manufacturer of the antifreeze foradditional instructions.

System water including additives must bepractically non-toxic, having a toxicityrating or Class of 1, as listed in ClinicalToxicology of Commercial Products.

Use of Antifreeze in the Boiler System

NEVER use automotive or ethylene gly-col antifreeze or undiluted antifreeze inthe primary system as freeze protection.This can cause severe personal injury,death or substantial property damage ifignored.

Determine the antifreeze fluid quantity usingthe system water content volume and followingthe antifreeze manufacturer instructions.

The water volume of the PRESTIGE Excellenceis approximately 5 gallons (includes Boiler andDHW outer tank). Remember to include the vol-ume of the expansion tank.

Check with local codes requirements for theinstallation of backflow preventers or actualdisconnect from the boiler’s cold water fill ormake up water supply line.

Massachusetts Code requires a pressurereducer/backflow preventer if antifreezeis used.

Ensure the concentration of antifreeze to waterdoes not exceed a 50/50 ratio.

System water, including additives, mustbe practically non-toxic, having a toxicityrating or Class of 1, as listed in ClinicalToxicology of Commercial Products.

Ensure the domestic inner tank of thePRESTIGE Excellence water heater isproperly filled and pressurized prior tofilling the boiler system. Reference thePRESTIGE Excellence water heater forproper guidelines on filling the innertank. Failure to comply could result indamage of the inner tank.

Filling the Boiler System

1. Close the boiler drain valve located on thebottom of the unit and any manual or auto-matic air vent in the system.

2. Open all system isolation valves.

3. Fill the boiler system to correct systempressure. Correct pressure will vary witheach application.

Typical residential system fill pressure is12 psi. System pressure will increasewhen system temperature increases.Operating pressure of the system shouldnever exceed 25 psi.

4. Purge air and sediment in each zone of theboiler system through the purge valve.Open air vents to allow air to be purged inthe zones.

5. Once the system is completely filled andpurged of all air and sediment, check thesystem pressure and check/repair anyleaks.

Unrepaired system leaks will cause con-tinual makeup water to be added to theboiler. Continual makeup water couldcause mineral buildup within the heatexchanger, reducing the heat transfer,causing possible heat buildup and even-tual heat exchanger failure.

Check Low Water Cut-Off Device

- The PRESTIGE Excellence is providedwith a factory installed LWCO device thatmeasures system pressure of more than 10psi.

- Remove the front jacket panel and check forcontinuity across the low water cut-offdevice wire terminals. The contacts shouldbe closed when system pressure is greaterthan 10 psi. See item 5, on Fig. 27 page 63.

Check For Gas Leaks

Prior to start-up and during initial opera-tion, smell near the floor and around theunit for gas odorant or any unusual odor.Do not proceed with the start-up if thereis any indication of a gas leak. Any leaksfound must be repaired immediately.

Propane installations only - The propanesupplier mixes an odorant with thepropane to make its presence detectable.In some cases the odorant can fade andthe gas may no longer have an odor.

Prior to start-up of the unit and periodi-cally after start-up have the propanesupplier check and verify the odorantlevel.

Check Thermostat Circuit

- Disconnect the external thermostat wiresfrom the 24V terminal strip on the wiringpanel.

- Connect a voltmeter across the wire ends ofthe external thermostat wiring.

- Close each thermostat, zone valve andrelay in the external circuit one zone at atime and check the voltage reading acrossthe wire ends.

- There should NEVER be voltage measuredat the wire ends.

- If voltage is measured at the panel under anycondition, check and correct the externalwiring.

In systems using 3-wire zone valves,backfeed of voltage to the unit is a com-mon problem. Use an isolation relay toprevent voltage from the external circuitentering the PRESTIGE Excellence con-trol panel.

- Reconnect the external thermostatwires to the 24V terminal strip on thewiring panel.

Inspection of Condensate Drain Assembly

1. Inspect and ensure the condensate drainassembly is properly installed as describedon page 22 and shown in Fig. 15 on page 23.

2. Remove the plug from the condensate drainassembly and fill the trap with fresh water.

The condensate drain assembly must befilled with water when the PRESTIGEExcellence is in operation. The conden-sate drain assembly prevents flue gasemissions from entering the condensateline. Failure to ensure trap is filled withwater could result in severe personalinjury or death.

3. Re-Install plug in condensate drain assem-bly.

SECTION XI - Outdoor Reset Control

The boiler setpoint for a heating call can befixed or vary with the outdoor temperature. Ifthe application requires a constant supply tem-perature from the boiler, the outdoor tempera-ture sensor should not be connected to the boil-er. If an outdoor temperature sensor is con-nected to the boiler, the outdoor reset functionis automatically enabled and will vary the CHsetpoint with the change in outdoor tempera-ture. The outdoor reset function has no affecton the DHW setpoint during a domestic call.

Mounting the Outdoor Sensor

1. Remove the front cover and mountingscrews / anchors from the sensor enclosure.

2. When mounting the enclosure the exteriorwall selected should represent the heat loadof the building. Typically a northern ornortheastern wall will suit most buildings.A southern facing wall may suit buildingsthat have large glass walls or windows onthe southern face.

3. Ensure the sensor enclosure is shieldedfrom direct sunlight or the effects of heat orcold from other sources (exhaust fans,appliance vents...) to prevent false temper-ature sensing.

4. Mount the sensor enclosure at an elevationon the exterior wall to prevent accidentaldamage or tampering.

5. Avoid mounting the enclosure in areas sub-jected to excessive moisture.

6. Once an area on the exterior wall has beendetermined, to affix the enclosure use theenclosure as a template to mark the locationof the mounting screws.

7. Using a 3/16” drill bit, drill 2 pilot holes onthe marked locations.

8. Tap the enclosed plastic anchors into thepilot holes. Use care not to damage theanchors.

9. Mount the sensor enclosure using thescrews provided.

Wiring the Sensor

1. Remove the sealing nut and sealing gasketfrom the sensor enclosure.

2. Route two 18 gauge wires through the seal-ing nut and gasket. Connect the wires tothe sensor terminals 1 and 2.

3. Re-insert the sealing gasket and tighten thesealing nut to the sensor enclosure.

4. Route the sensor wire back to the PRES-TIGE Solo boiler, ensuring the wires arenot run parallel to telephone or powercables.

If the sensor wires are located in an areawith sources of potential electromagneticinterference (EMI) the sensor wiresshould be shielded or the wires should berouted in a grounded metal conduit. Ifusing shielded cable, the shielding shouldbe connected to the common ground ofthe unit.

5. Connect the sensor wires to the outdoor sen-sor terminals on the 24V terminal strip locat-ed inside the boiler enclosure (see boilerwiring diagram, Fig. 20 page 29).

SECTION XII - External ModulatingControl

The boiler can directly accept an analog 0-10VDC signal to control the firing rate from anexternal modulating boiler controller.

Wiring the Modulating Controller

Run two 18 gauge wires from the externalmodulating boiler controllers 0-10 VDC boileroutput to the external input terminals on thelow voltage terminal strip inside the boiler. (seeboiler wiring diagram, Fig. 20 page 29). Thissignal will both enable and modulate the boil-er. No wiring is required at the thermostat (T-T) terminals 7 and 8 of the boiler.

Ensure that the polarity of the connec-tions from the external modulating boil-er controller to the boiler is correct.Reversed polarity could lead to erraticand/or no response from the boiler con-troller.

Parameter Adjustment

The Prestige MCBA control module must beprogrammed to accept the 0-10 VDC signalfrom the external modulating boiler control.

CH Operating Signal Section(Parameter 45)

Follow the procedure for entering the MCBAAccess Code on page 49, and then change thesetting of Parameter 45 from the factory settingof 00 to 02.

Ensure that Parameter 4 is set above thehighest setpoint of the external modulat-ing control. Parameter 4 is a boiler hightemperature limit when using an exter-nal modulating controller.

Programming of External ModulatingControl

The external modulating control must be pro-grammed to send 1.8 VIC to enable the boilerand run it at low fire, and 10 VIC to run theboiler at high fire. Once the control enables theboiler, it must wait 2 minutes to allow the burn-er to stabilize before modulating the boiler.

Check the cold fill pressure for the system, typ-ical cold water fill pressure is 12 psig.

Verify the system pressure, as the unit operates athigh temperature, to ensure the pressure does notexceed 25 psig. Excessive pressure reading indi-cates expansion tank sizing is incorrect or systemperformance problems.

Inspect air vent and air separators in the sys-tem. Remove the caps on automatic air ventsand briefly depress the valve stem to flushvent. Replace the cap when completed. Ensurevents do not leak, replace any leaking vents.

WARNING

Check Expansion Tank

Refer to Section IV - Boiler Piping for rec-ommended location of the expansion tankand air eliminators.

Closed -Type Tank:

- Ensure tank is partially filled withwater leaving an air gap as a cushion.Refer to the manufacturer’s instructionfor proper fill level.

- Ensure the tank is fitted with a devicethat reduces gravity circulation of air-saturated tank water back into the sys-tem. This device prevents air frombubbling up through the water as itreturns from the system.

- Ensure no automatic air vents are usedin the system. This will allow air toescape from the system instead ofreturning to the tank.

Diaphragm Tank:

- Ensure the system contains a minimum ofone automatic air vent. Recommendedlocation of the air vent should be atop anair eliminator.

- Remove the tank from the system andcheck the charge pressure. For residen-tial applications the charge pressure istypically 12 psig. If tank does not holda charge pressure, then the membrane isdamaged and the tank should bereplaced.

Check Boiler Relief Valve

Inspect the relief valve and lift the lever to ver-ify flow at least annually or as recommendedon the warning tag of the valve.

Before manually operating the pressurerelief valve, ensure the discharge piping isdirected to a suitable place of disposal toavoid a potential scald hazard. The dis-charge piping must be full size withoutrestriction and installed to permit com-plete drainage of both the valve and line.

If after closing the valve, the valve fails to seatproperly or continually weeps, replace therelief valve. Ensure the cause of the reliefvalve to weep is the valve itself, not due to sys-tem over-pressurization caused by an expan-sion tank that is waterlogged or undersized.

Inspection of Ignition Electrode

Remove the ignition electrode from the burnermounting plate.

Remove any white oxides accumulated on theelectrode using fine grit sandpaper or steel wool.If the electrode does not clean to a satisfactorycondition, replace the ignitor .

When replacing the ignition electrode, ensurethe gasket is in good condition and correctlypositioned. Replace gasket if necessary.

Check Ignition Wiring and Ground Wiring

Inspect the burner wiring from the burner con-trol module to the ground terminal behind thecontrol panel.

Ensure wiring is in good condition and secure-ly connected.

Check ground continuity of the wiring to theboiler jacket or piping using a continuity meter.

Replace and correct ground wire if ground con-tinuity is not completed and satisfactory.

WARNING


58

Carefully remove the burner mounting plateassembly from the heat exchanger. Ensurecombustion chamber insulation is not damagedduring removal of burner mounting plateassembly. See WARNING on page 61.

Remove the burner head mounting screws andremove the burner head. Inspect the burnerhead for deterioration. Use compressed air ora vacuum to clean the burner head.

Remove the venturi and gas valve assemblyfrom the blower.

Use a vacuum cleaner or compressed air toclean the interior of the blower assembly.Inspect the blower blades to ensure they areclean and not damaged.

Re-assemble the venturi and gas valve onto theblower. Ensure the venturi gasket is in goodcondition, positioned correctly and replace gas-ket if necessary.

Re-assemble the burner head onto the burnermounting plate. Ensure the burner head gasketis in good condition, positioned correctly andreplace gasket if necessary.

Re-assemble the burner mounting plate assem-bly onto the heat exchanger. Ensure the burnerplate gasket and combustion chamber insula-tion is in place and not damaged, replace gas-ket and insulation if necessary. See WARNINGon page 61.

Re-assemble the blower onto the burnermounting plate and reconnect the wiring har-ness connectors.

Re-assemble the gas supply connection andrectifier to gas valve. Open the external manu-al gas valve. Check gas piping for any leaks asoutlined on page 38 and repair if necessary.Place the unit back into service.


59

Check Flame Signal

The flame signal should be a min. 3μ Α −DC.

Check the ignitor for fouling or damagedinsulation if a low flame signal is read.

Check ground wiring and continuity as a causefor low flame signal. Replace ignitor if condi-tions are satisfactory.

Check Combustion Levels

Refer to page 38 of this manual for measuringcombustion levels and burner adjustments.

Check Flue Gas Temperature

1. Adjust the boiler to fire at HIGH fire, seepage 42. Place the control display to INFOR-MATION mode, see page 44 for procedures.

2. The flue gas temperature is indicated onthe display when the first digit is 5. Themeasured temperature (shown as the last 3digits) should not be more than 54ºF high-er than the measured supply water temper-ature.
