Originally founded as Bullocks Manufacturing during the post-war residential

housing boom, I.C.E. Manufacturing was recognized for innovation and

excellence early in our history. After the company established a reputation for

designing, manufacturing and installing natural gas conversion burners for oil

and coal-fired furnaces, founder Don Bullocks returned from an ASHRAE trade

show with a natural gas line burner. Inspired, he set out to manufacture the first

direct-fired makeup air unit in his home country of Canada.

Today, the natural gas revolution continues with I.C.E. Manufacturing at the

forefront of the commercial direct-fired industry. Don had the vision long before

many others by designing a product that has outlived his legend. Our BMA

Series is named for him (Bullocks Makeup Air). This forward thinking has carried

on through such advanced products as the HTDM, the gas valve technology

available on the BMA, and the industrial-quality GIDM product line.

All of our products have withstood the test of time. Many new products are on

the horizon to meet the ever-increasing concern over energy costs, consumption

and impact on our environment. We are building on our heritage to bring

exceptional gas-fired products to market.

I.C.E. is committed to success – the success of our customers and our

employees. To us, success is driven by loyalty that comes from service, quality

and innovation. With our vast experience in the HVAC industry, we continue to

listen to and understand the needs of our customers. And we trust we will be

able to serve you well into the future.

Application Guide For Indirect Fired GIDM/GIDMH Series

• GIDM unit models are designated by their MBH output. Thus a GIDM 75 has 750 MBH output, or 750,000 BTUH.

• All GIDM units are 80% efficient at high fire, thus, output is BTUH input * 0.80

• Once you have chosen your required BTUH output, you can use BTUH output/0.80 to find your required input, or actual gas consumption. Using the desired output you can select your model.

• Choose your airflow (this may be your first step if the unit is applied in a make-up air situation)

• Calculate your TSP (add your ESP with your accessories – accessory pressure drops can be found on page 6). With your airflow and TSP selectedyou can find your BHP from the charts on pages 10-12

• Unit weights can be found on page 8 & 9

• Given the entering and leaving air dry bulb temperatures or temperature rise, the equation below can be used to calculate the required MBH capacity

MBH Capacity = (CFM x C x (LAT-EAT))/0.80/1000

MBH capacity: BTUH/1000 (British Thermal units per hour)

CFM: Cubic Feet per minute of air

C: Gas constant of 1.08 based on air density at 75 deg. F

EAT: Entering air dry bulb temperature (deg. F)

LAT: Leaving air dry bulb temperature (deg. F)

0.8: GIDM Series Efficiency

Example For Make-Up Air

A manufacturing facility needs pressurization via make-up air. 10% pressurization is deemed to be appropriate and it is determined that 25,720 CFMexhaust is required. -20 deg. F is the design ambient, and desired discharge temp is 70 deg. F. Units will be roof mounted, down discharge, and willhave an ESP of 0.60" W.C. Select the appropriate GIDM model, and find the BHP for the unit.

Selection:

• Since we are exhausting 25,720 CFM, and desire 10% pressurization, we can calculate that we need 28,300 CFM of supply air (25,720 + 10% = 28300)

• We know our EAT = -20 deg. F, and LAT = 70 deg. F, thus we can calculate:

• MBH Output Capacity = (CFM x C x (LAT-EAT))/1000

• MBH Output Capacity = (28,300 x 1.08 x (70 - (-20)))/1000

• MBH Output Capacity = 2,750.00

• The closest model available is the GIDM 275 which has 2,750 MBH output, and 3,437.5 MBH input

We can now calculate our TSP:

• We are selecting the basic options – inlet filters and damper

• Inlet damper = 0.1" W.C (Page 6)

• Inlet Filters = 0.3" W.C (Page 6)

• TSP = ESP + Accessories

• TSP = 0.60 + 0.1 + 0.3

• TSP = 1.0" W.C.

• Consulting the chart for the GIDM 275 (page 12) at 28,300 CFM and 1.0" W.C we find our BHP = 16.28 BHP – Thus we need a 20.0 HP motor minimum.

Example for Heat-Vent Unit

A small warehouse needs a minimum of 20% fresh air in unoccupied (night time) mode and 100% fresh air in occupied mode (during the day with forkliftin the building). It has been calculated that at -30 deg. F the room loses 1,000,000 BTUH. It has been determined that 11,000 CFM is required for theapplication. The outdoor air is -30 deg. F, and desired leaving air is 75 deg. F. Return air will be 70 deg. F. ESP is calculated to be 0.5" W.C. Select theappropriate model and find the BHP for the unit.

Selection:

Part 1 (Unoccupied mode)

• We only bring in 20% outside air in this mode, thus 2200 CFM is outside air and 8800 CFM is return air

• We know our EAT for outside air = -30 deg. F, and LAT = 75 deg. F, thus we can calculate:

• MBH Capacity = (CFM x C x (LAT-EAT))/1000

• MBH Capacity = (2,200 x 1.08 x (75 - (-30)))/1000

• MBH Capacity = 249.48

• We also know that the room is losing 1,000 MBH, thus we need to add that to the calculation. Thus the total Heat input capacity required = 1,250 MBH

• Before we select our model we must check the occupied mode to ensure we have sufficient heat capacity.

2

Part 2 (Occupied mode)

• We will be delivering 11,000 CFM of outside in this mode

• We know our EAT for outside air = -30 deg. F, and LAT = 75 deg. F, thus we can calculate:

• MBH Capacity = (CFM x C x (LAT-EAT))/0.80/1000

• MBH Capacity = (11,000 x 1.08 x (75 - (-30)))/0.80/1000

• MBH Capacity = 1,247.40

• Thus to satisfy both options we need to use a GIDM 125.

Note: In this example we are assuming there is an alternate source of heat that will be used during occupied mode to make-up for the heat loss of thewarehouse, which will not be used in un-occupied mode.




• Inlet Filters = 0.3" W.C (Page 6)


• TSP = 0.50 + 0.1 + 0.3

• TSP = 0.9" W.C. (Round up to 1.0" W.C)

• Consulting the chart for the GIDM 125 (page 10) at 11,000 CFM (Use 11,574 CFM) and 1.0" W.C we find our BHP = 5.75 BHP – We can use a 7.5 hp motor.

Example for a Heating Only Unit

A door heater for a large overhead door can potentially see 100% fresh air during times when the overhead doors open frequently. Thus a durable GIDMunit should be selected for this application. 18,000 CFM at 0.5" W.C is determined to be the appropriate amount of air for the vestibule, and 1250 MBHis calculated to be the appropriate amount of heat capacity required. Select the appropriate model and find the BHP for the unit.

Selection:

• Since the heating load calculation has already been completed we simply need to use the heating capacity and match it up with the appropriateGIDM model

• A GIDM 125 is the appropriate model for 1250 MBH




• Inlet Filters 0.3" W.C (Page 6)


• TSP = 0.50 + 0.1 + 0.3

• TSP = 0.9" W.C. (Round up to 1.0" W.C)

• Consulting the chart for the GIDM 125 (page 10) at 18,000 CFM (this value falls between 16,534 CFM and 19,290 CFM) and 1.0" W.C we find ourBHP is between 9.59 BHP and 13.12 BHP. A 15 HP motor should be used.

GIDM Series Temperature Control PackagesBuilding makeup air systems maintain a constant supply air temperature to the space using a discharge temperature controller. The burner output ismodulated over a wide range to compensate for fluctuations in the incoming ambient air temperature. A gas valve regulates output according to thedemand sensed by a discharge air sensor. The fan and heat system functions are typically controlled by a remote panel with a system andsummer/winter switch or a building management system.

Types of Gas Valve Control Available

A) Modulating Discharge Air Temperature ControlThis type consists of a discharge air sensor in the discharge of the unit. The temperature set point is set at the unit and the burner will then modulate tomaintain this discharge temperature.

B) Modulating Discharge Air Temperature Control with Remote Manual Adjustment (RTS)This type consists of a modulating discharge air sensor and a remote temperature selector. The operation of this type is the same as the above (A).However the discharge temperature may be remotely adjusted by the remote temperature selector.

C) Modulating Discharge Air Temperature Control with Remote Temperature Adjustment and Space Override (Brings Unit to Full Fire)This type consists of a modulating discharge air sensor, remote temperature selector, and a space override temperature stat. This is commonly usedwhere there is wide, fast indoor temperature fluctuations (eg. garage) and/or where fine temperature control is not essential, and/or when thetemperature rise is low (eg. 40 deg. F or less). The operation is the same as above (B) however when the space stat requires heat the furnace goes to fullfire regardless of the discharge temperature, until the space thermostat is satisfied.

D) Modulating Discharge Air Temperature Control with Remote Manual Adjustment (RTS'S) and Space Thermostat for Resetting Discharge Air Temperature SettingsThis type consists of a modulating discharge air sensor, a remote temperature selector for first temperature setting (eg. 75 deg. F), a second remotetemperature selector for Override setting (eg. 90 deg. F) and a space thermostat for switching. This type is used where there is moderate indoortemperature fluctuations and/or where fine temperature control is essential and/or when the unit temperature rise is high. The operation is the same as inC however the second remote temperature selector limits the discharge air temperature when the space thermostat calls for full fire. The burner willmodulate to maintain the second set point until the space thermostat is satisfied.

Note: The space stat may be replaced with dry contacts to allow a building management system to do the switching.

E) Building Management Control InterfaceThis type consists of a DDC Gas modulating interface (0-10Vdc or 4-20mA). This allows a building management system to tie into the unit controls. Thebuilding management system now controls the discharge temperature of the unit and the burner will modulate to maintain that temperature.

F) Modulating Space Thermostat with Auto Discharge Temperature ResetThis type consists of a modulating duct stat and a modulating space stat. This type is used where space loads continuously change. This system willautomatically adjust the discharge temperature to accommodate for the load changes providing precise space temperature control.

Miscellaneous Control Options

Freeze ProtectionSpecified to protect against untempered air entering the space. The freeze thermostat, also known as an auto low limit, is located in the discharge airand is wired in parallel with a time delay relay. In the event that the discharge air temperature is not above the freeze thermostat setting, within a presettime during start-up and under normal operation the unit will shut down.

Inlet Air ControllerFeatures an adjustable thermostat which monitors outdoor air temperatures. When the temperature exceeds the setting of the thermostat, the burner willnot operate even when the unit is in the winter mode.

Night SetbackThis feature is available as an option on all temperature control systems. By lowering the discharge air temperature requirements during unoccupiedperiods the owner can realize operating economies and still provide heat to the space as required. During the occupied cycle the unit will be brought onthough an interlock, timeclock or switch. During the unoccupied period the timeclock provided, switches the system control to a single stage thermostatset at the desired unoccupied temperature. The unit will then be started intermittently to provide heat to maintain the space at the unoccupiedtemperature setpoint.
