sound and vibration levels

All mechanical equipment generates some sound and vibration that may require attenuation. Libraries, private offices, and hospital patient rooms will require more attenuation and in such cases an acoustical consultant may be retained to assist in the application. Locating the equipment away from the critical area is desirable within ducting limitations. Frequently, units can be located above utility areas, corridors, restrooms, and other non-critical areas. Generally, a unit should be located within 15 feet of a primary support beam. Smaller defections mean lesser vibration and noise transmission.

Roof curb must be installed level. If roof is pitched it will be necessary to construct a sub-base on which to install the curb.

Install the unit over roof decking with 2" acoustic fiberglass lining within curb area for sound attenuation. The return air duct should be acoustically lined and should be installed with a flexible connection. If the ceiling space is used as a plenum, the acoustically lined return intake duct should form an inverted tee with five foot minimum legs in each direction.

The discharge duct should be acoustically insulated and should have a flexible connection as illustrated.

3. Outside dimensions must be held when installing curb.

Top surface must be level and straight to insure weathertightness. All corners must be square.

4. All dimensions are +1/8 inch.

5. Final electric and gas connections must be made after unit is installed to allow for tolerance in setting of unit on curb.

For electrical power supply allow approximately eight feet of wire, plus provisions for weathertight flexible conduit for connection to unit, as required by local codes.

6. Maintain an 12-inch minimum height from top of roof deck to top of curb.

7. Caulk butt joints after curb is assembled and installed on roof structural members and roof flashing is added.

curb or sub-Base mounted sites

An optional 16-inch high roof curb is available to simplify site preparation and raise the unit above roof water and snow level for drainage. It can be installed with the roof, and in advance of the unit. The curb is shipped knocked down with separate instructions (Literature 5-590) for its assembly, flashing, and sealing with the roof. A sub-base must be furnished by the installer if no curb is supplied for the roof. The sub-base, either steel or concrete, must provide required support with the unit bolted to sub-base. The following are some general guidelines for roof curb installed units:

1. The roof structure must be adequately designed to support the live weight load of the unit and any other required support structure. For the bearing loads normally encountered, the roof curb should be supported at points no greater than five feet apart. Additional truss reinforcement should be provided, if necessary.

2. Roof curbs supplied by Modine are fabricated from 16 gauge galvanized steel and supplied knocked down for assembly on the job site. The curb consists of two side pieces, two end pieces, gasketing, four joiner angles, four 2x4 inch wood nailing strips, nuts, bolts, and washers. Roof curbs over 120 inches long include two additional side pieces and two splice plates.

slab mounted sites — models HBG/HBP &

HcG/HcP

For ground level installation of a front-discharge unit prepare a level concrete slab at least four inches thick on adequate footings and a generous bed of gravel for drainage. (See

Figure 5.1). The slab should include threaded 5/8-inch anchor bolts spaced according to Figure 5.2. Anchor bolts should extend at least 1-1/2" above the surface of the floor to allow clearance for mounting washers, nuts and bolts (mounting washers, nuts and bolts by others). The slab should extend out at least six inches around the perimeter of the unit.

Utility and control connections can be made to the unit from the bottom for roof curb-mounted units or through the fixed side panels for horizontal supply and return units. Holes can be made in fixed side panels to accommodate utility connections as specified according to the unit dimensional drawings.

Sealing of holes cut in the unit casing for utility connections should be done with care to prevent air and water leaks.

rigging instructions

Four 3/4-inch holes at the extended ends of the mounting channels are supplied to facilitate lifting the unit with eyebolts to be furnished by the installer. For either crane or helicopter lift of the equipment to the rooftop, connect sturdy steel cables with eye loops as illustrated in Figure 6.2. To prevent cable from marring the cabinet end tops, use spreader bars or an angle iron frame at least 6" longer and wider than the unit to spread the lifting cables above the unit. For stability in lifting and lowering, include a spreader piece between the two cable spreaders as illustrated in Figure 6.2.

unit installation

Follow site preparation instructions for applicable curb, sub-base, or slab sites before installation. Check Model

Identification Plate of unit with plans to be sure unit is properly located. (See pages 56 and 57). Also inspect damper motors and dampers for proper type (e.g., two-position, modulating, fresh air only, fresh and return air, etc.). Although units may look outwardly similar, their function, capacities, options, and accessories will often vary. Check dimensions.

If unit is to be installed on a factory-supplied curb:

1. Install roof curb using previous roof curb instructions (pages

4 and 5).

2. Thoroughly clean and dry the top of the curb surface.

3. Lay a bead of weather resistant caulking on top perimeter of roof curb as illustrated in Figure 4.3.

4. Orient hoisted unit to its ductwork and set it down evenly on curb.

5. Make final unit connections to the electric power supply and remote control circuits. Connect the gas lines to the unit heating compartment in accordance with the submittal drawings and architect plans. Caulk all utility line clearance holes on the unit after connections are completed.

If unit is to be installed on a separate sub-base or slab, use steps 4 and 5.

venting

1. Installation of venting must conform with local building codes, or in the absence of local codes, with the National

Fuel Gas Code, ANSI Z223.1 (NFPA 54) - Latest Edition.

In Canada, installation must be in accordance with CAN/

CGA-B149.1 for natural gas units and CAN/CGA-B149.2 for propane units.

2. For HBG/HCG/HDG/HPG units, do not operate duct furnaces without the factory supplied vent cap (shipped loose) fastened securely in place. HBP/HCP/HDP/HPP units are shipped with the power exhauster discharge cover factory installed.

3. For HBG/HCG/HDG/HPG units, do not modify or obstruct the vent cap in any manner. For HBP/HCP/HDP/HPP units, do not modify or obstruct the combustion air inlet louvers or the power exhauster discharge cover.

4. Do not add any vents other than those supplied by the manufacturer.

To prevent premature heat exchanger failure, the input to the appliance, as indicated on the serial plate, must not exceed the rated input by more than 5%.

1. Installation of piping must conform with local building codes, or in the absence of local codes, with the National Fuel Gas

Code, ANSI Z223.1 (NFPA 54) - Latest Edition. In Canada, installation must be in accordance with CAN/CGA-B149.1 for natural gas units and CAN/CGA-B149.2 for propane units.

2. Piping to units should conform with local and national requirements for type and volume of gas handled, and pressure drop allowed in the line. Refer to Table 13.2 to determine the cubic feet per hour (cfh) for the type of gas and size of unit to be installed. Using this cfh value and the length of pipe necessary, determine the pipe diameter from Table 7.1. Where several units are served by the same main, the total capacity, cfh and length of main must be considered. Avoid pipe sizes smaller than 1/2". Table 7.1 allows for a 0.3" W.C. pressure drop in the supply pressure from the building main to the unit. The inlet pressure to the unit must be 6-7" W.C. for natural gas and 11-14" W.C. for propane gas. When sizing the inlet gas pipe diameter, make sure that the unit supply pressure can be met after the 0.3"

W.C. has been subtracted. If the 0.3" W.C. pressure drop is too high, refer to the Gas Engineer’s Handbook for other gas pipe capacities.

3. The gas piping to the unit can enter the unit from the side of the unit or from below (curb mounted units). Drill locator dimples are located in the side and bottom of the unit for field drilling the hole for the gas pipe entry. Install a ground joint union with brass seat and a manual shut-off valve external of the unit casing, and adjacent to the unit for emergency shut-off and easy servicing of controls, including a 1/8" NPT plugged tapping accessible for test gauge connection (See Figure 7.1). Verify the manual shut-off valve is gas tight on an annual basis.

note: Some local codes may require a manual shutoff valve external to the unit casing. In this case, the gas piping must exit the unit through the side piping hole, followed by the manual shut-off valve, piped back into the unit corner post, through the unit bottom, and lead to an additional union and manual shut-off valve.

4. Provide a sediment trap before each unit in the line where low spots cannot be avoided (See Figure 7.1).

5. When Pressure/Leak testing, pressures above 14" W.C.

(1/2 psi), close the field installed shut-off valve, disconnect the appliance and its combination gas control from the gas supply line, and plug the supply line before testing. When testing pressures 14" W.C. (1/2 psi) or below, close the manual shut-off valve on the appliance before testing.

cooling coil installation

Models with a cooling section can be provided with either a factory installed direct expansion (DX) evaporator, a chilled fluid

(for use with water, ethylene glycol, or propylene glycol fluids) coil, or the coil can be field supplied and installed by others.

For units equipped with a factory installed cooling coil (Digit

23 = 1), refer to the packing slip to determine the coil type provided. The cooling section is located downstream of the duct furnace heat exchanger in a blow-through configuration, preventing condensation on the heat exchanger in the cooling mode. Thus, a stainless steel heat exchanger is not required when a cooling section is used. (However, a stainless steel heat exchanger is still recommended when the combined entering/return air to the unit is below 40°F.)

The cooling section includes a full coverage, 3-way sloping

409 stainless steel drain pan to remove condensate from coil headers, thermal expansion valves, and refrigerant piping.

Insulation is standard on outdoor units and optional on indoor units and double wall construction is optional on all units. The cabinet includes two doors, a removable upper door for service access to the coil once the plumbing has been installed and a lower door which includes a factory supplied 1" stubbed drain connection to the exterior of the cabinet. Field connections for coil inlet and outlet piping can be made through the cabinet corner post or back of the unit. The cooling section duct transition includes 1-1/2" flanges for fastening the sides of the coil. The bottom duct transition is angled to remove any condensation that may be entrained in the supply air stream.

For field supplied coils, do not exceed the maximum coil dimensions listed in Literature 82-135. If the coil supplied is smaller than the listed dimensions, field supplied blank off plates are required to prevent air bypass around the coil.

The coil is supported by two 14 gauge support rails which contain mounting provisions for fastening 4", 5", 6", 7.5", 8.5", and 10" deep coils. When obtaining the specifications from a coil manufacturer, it is important to obtain the pressure drop through the coil so that the proper motor horsepower can be selected.

The condensate drain line needs to include a P-trap immediately downstream of the connection to the unit. This trap should extend at least two inches below the connection to prevent air pressure from forcing air into the unit. The trap should be primed with a water/glycol solution to prevent freezing. All points where refrigerant, water or condensate lines enter the structure should be sealed and vibration dampened.

Include shut-off valves to isolate the cooling coil from the system in order to remove the coil for service or replacement without draining the entire system. For additional guidelines, refer to the ASHRAE Fundamentals Handbook section of piping recommendations.

General refrigerant Piping

1. All field piping must be self-supporting. Long runs of piping need to be periodically supported to prevent excess vibration that can damage the piping and joints. It is recommended to provide dampening supports at intervals of length equivalent to 15 tube diameters.

2. All field brazing and welding should be performed using

high quality materials and an inert gas purge (such as

nitrogen) to reduce oxidation of the internal surface of the coil.

3. System piping should be flexible enough to allow for thermal

expansion and contraction of the coil.

direct expansion (dX) Piping

The refrigerant lines should be insulated to prevent warming or cooling of the refrigerant. If the suction line is allowed to be cooled, liquid will condense in the line and can severely damage the compressor. If the liquid line is warmed, the refrigerant can

"flash" into a gas. This will cause erratic operation of the expansion device and impair the heat transfer ability of the cooling coil.

8. Failure to obtain a high vacuum is indicative of a great deal of moisture or a small leak. Break the vacuum with a charge of dry nitrogen or other suitable gas and recheck for leaks (soapy water works well). If no leaks are found, continue vacuuming the coil until the desired vacuum is reached.

chilled fluid Piping

To prevent noise within a system, an air vent is necessary to bleed off the accumulated air in the system. The vent should be located on the top of the inlet manifold where the air collects. Air in the system will generate noise and may cause water hammer that can damage the joints of the piping and the cooling coil.

The outlet manifold should have a drain installed on the bottom of the manifold to allow for periodic flushing of the system to remove sediments and corrosion products from the cooling coil. The lines between the unit and the structure should be insulated to prevent freezing of the water. Leak test the coil and connections as outlined in the section on this page.

Suction Connection

1. Inspect the refrigerant distributor and verify that the nozzle

is in place.

2. Connect the suction line and suction connection.

3. Install the expansion valve (By Others). Follow the

expansion valve manufacturer's recommendations for

installation to avoid damaging the valve.

4. The expansion valve remote sensing bulb should be

securely strapped to the horizontal run of the suction line

at the 3 or 9 o'clock position and insulated.

5. Connect the liquid line to the expansion valve.

6. Leak test the coil and connections as outlined in the section on this page.

7. Use a vacuum pump to evacuate the coil and any

interconnecting piping that has been open to atmosphere.

Measure the vacuum in the piping using a micron gauge

located as far from the pump as possible (the vacuum at

the pump will be greater than the rest of the system).

Evacuate the coil to 500 microns or less then close the

valve between the pump and the system. If the vacuum

holds to 500 microns or less for one minute, the system

is ready to be charged or refrigerant pumped down in

another portion of the system can be opened to the coil.

A steady rise in microns would indicate that moisture is still

present and that the coil should be further vacuumed until

the moisture has been removed.

leak testing the coil and connections

1. Pressurize the coil, expansion valve assembly and suction connection to 100 psig with dry nitrogen or other suitable gas.

2. The coil should be left pressurized for a minimum of

10 minutes. a. If the coil holds the pressure, the hook-up can be considered leak free.

b. If the pressure drops by 5 psig or less re-pressurize the coil and wait another 10 minutes. If the pressure drops again, there is more than likely one or more small leaks which should be located and repaired.

c. Pressure losses greater than 5 psig would indicate a larger leak that should be isolated and repaired.

3. Be sure to check valves and fittings as potential sites for leakage or bleed. If the coil itself is found to be leaking, contact your local factory representative.

start-uP Procedure

IMPORTANT

1. To prevent premature heat exchanger failure, observe

heat exchanger tubes by looking at the heat exchanger

through the field installed access openings in connecting

ductwork in model HBG/HBP or the unit access doors in

models HDG/HDP, HCG/HCP, or HPG/HPP. If the bottom of

the tubes become red while blower and duct furnace are in

operation, check to be sure the blower has been set to the

proper rpm for the application. Refer to page 15 for Blower

Adjustments.

2. Start-up and adjustment procedures should be performed

by a qualified service agency.

1. Turn off power to the unit at the disconnect switch. Check that fuses or circuit breakers are in place and sized correctly. Turn all hand gas valves to the “OFF” position.

2. Remove the duct furnace and blower exterior panels and open the electrical compartment door.

3. Check that the supply voltage matches the unit supply voltage listed on the Model Identification plate. Verify that all wiring is secure and properly protected. Trace circuits to insure that the unit has been wired according to the wiring diagram.

4. Check that all electrical and gas connections are weatherized.

5. For HBG/HCG/HDG/HPG units, check to insure that the vent cap is installed and free from instruction. For HBP/HCP/

HDP/HPP units, check to insure that the combustion air inlet louvers and the power exhauster discharge cover is free from obstructions.

6. Check to see that there are no obstructions to the intake and discharge of the unit.

7. Check the belt tension and sheave alignment. Refer to Blower

Adjustments for proper belt tension.

8. Check bearings for proper lubrication. For units provided with pillow block bearings (See Model Nomenclature), refer to

Lubrication Recommendations for lubrication requirements.

9. Check to make sure that all filters are in place and that they are installed properly according to direction of air flow.

10. Perform a visual inspection of the unit to make sure no damage has occurred during installation.

11. Turn on power to the unit at the disconnect switch. Check to insure that the voltage between duct furnace electrical box terminals 1 and 2 is 24V.

12. Check the thermostat, ignition control, gas valve, and supply fan blower motor for electrical operation. If these do not function, recheck the wiring diagram. Check to insure that none of the Control Options have tripped.

13. For units with a return air damper, the return air damper linkage needs to be adjusted. Refer to Damper Linkage Adjustment.

14. Check to make sure that the damper opens properly without binding.

15. Check the blower wheel for proper direction of rotation when compared to the air flow direction arrow on the blower housing.

Blower wheel rotation, not air movement, must be checked as some air will be delivered through the duct furnace with the blower wheel running backwards.

16. Check the blower speed (rpm). Refer to Blower Adjustments for modification.

17. Check the motor speed (rpm).

18. Check the motor voltage. On three phase systems, check to make sure all legs are in balance.

5-572.7

19. Check the motor amp draw to make sure it does not exceed the motor nameplate rating. On three phase systems, check all legs to insure system is balanced.

20. Recheck the gas supply pressure at the field installed manualshut-off valve. The inlet pressure should be 6"-7" W.C. on natural gas or 11"-14" W.C. on propane. If inlet pressure is too high, install an additional pressure regulator upstream of the combination gas control.

21. Open the field installed manual gas shut-off valve.

22. Open the manual main gas valve on the combination gas valve. Call for heat with the thermostat and allow the pilot to light. (For HBP/HCP/HDP/HPP units, on a call for heat the power exhauster relay will energize the power exhauster motor. Once the power exhauster motor reaches full speed, a centrifugal switch in the motor will close before the pilot can light.) If the pilot does not light, purge the pilot line. If air purging is required, disconnect the pilot line at outlet of pilot valve. In no case should line be purged into heat exchanger. Check the pilot flame length (See Pilot Flame Adjustment).

23. Once the pilot has been established, check to make sure that the main gas valve opens. Check the manifold gas pressure

(See Main Gas Adjustment) and flame length (See Air Shutter

Adjustment) while the supply fan blower is operating.

24. Check to insure that gas controls sequence properly (See

Control Operating Sequence). Verify if the unit has any additional control devices and set according to the instructions in the Control Options.

25. Once proper operation of the unit has been verified, remove any jumper wires that were required for testing.

26. Close the electrical compartment door.

27. Replace all exterior panels.

Refer to page 58 for the Start-up Checklist.

If the unit has a cooling coil installed, verify the following upon start-up:

General - all coils

1. Proper air distribution is vital to coil performance. Air flow anywhere on the coil face should not vary by more than

20%.

2. Air velocities should be maintained between 200 and 550 feet per minute.

3. For chilled fluid coils, fluid velocities should be maintained within the recommended values of 1 to 8 fps for Water and

1 to 6 fps for Glycol solutions.

chilled fluid coils - initial start-up

1. Open all air vents so that air is eliminated from within the coil circuitry and headers. Verify that all vents and drains are not obstructed and do discharge a stream of water.

2. Fill the coil with water then close all vents.

3. Perform an initial hydrostatic leak test of all brazed, threaded or flanged joints, valves and interconnecting piping. Recheck the coil level and correct if necessary.

When the setup is found to be leak free, discharge and discard initial water charge. It is important that all grease, oil, flux and sealing compounds present from the installation be removed.

11

start-uP Procedure

Pilot Burner adjustment

The pilot burner is orificed to burn properly with an inlet pressure of 6-7" W.C. on natural gas and 11-14" W.C. on propane gas, but final adjustment must be made after installation. If the pilot flame is too long or large, it is possible that it may cause soot and/or impinge on the heat exchanger causing a fracture. If the pilot flame is shorter than shown, it may cause poor ignition and result in the controls not opening the combination gas control. A short flame can be caused by a dirty pilot orifice. Pilot flame condition should be observed periodically to assure trouble-free operation.

to adjust the Pilot flame

1. Create a call for heat from the thermostat.

2. Remove the cap from the pilot adjustment screw. For location, see the combination gas control literature supplied with unit.

3. Adjust the pilot length by turning the screw in or out to achieve a soft steady flame 3/4" to 1" long and encompassing 3/8"-1/2" of the tip of the thermocouple or flame sensing rod (See Figure 12.1).

4. Replace the cap from the pilot adjustment screw.

figure 12.1 - correct Pilot flame

3/4" to 1"

to adjust the manifold Pressure

1. Move the field installed manual shut-off valve to the “OFF” position.

2. Remove the 1/8" pipe plug in the pipe tee and attach a water manometer of “U” tube type which is at least 12" high.

3. Move the field installed manual gas shut-off valve to the

“ON” position.

4. Create a high fire call for heat from the thermostat.

5. Determine the correct high fire manifold pressure. For natural gas 3.5” W.C., for propane gas 10” W.C. Adjust the main gas pressure regulator spring to achieve the proper manifold pressure (for location, see the combination gas control literature supplied with unit).

6. If the unit has Electronic Modulation gas controls

(determine from the Model Identification Digit 12), the low fire gas pressure needs to be adjusted. Using Figure 13.1 for item number locations, this is accomplished as follows:

a.Disconnect power.

b.Remove all wires from duct furnace terminal “43” and remove cover plate (2).

c.Turn on power at the disconnect switch.

d.Remove the maximum adjustment screw (4), spring

(5), and plunger (8). A small magnet is useful for this purpose. CAUTION - The plunger is a precision part.

Handle carefully to avoid marring or picking up grease and dirt. Do not lubricate.

e.Using minimum adjusting screw (9), adjust low fire manifold pressure to 0.56" W.C. for natural gas and 1.6"

W.C. for propane gas.

f.Replace plunger and spring retainer, spring, and maximum adjusting screw in proper order.

g.Using maximum adjustment screw (4), adjust high fire manifold pressure to 3.5" W.C. for natural gas and 10"

W.C. for propane gas.

h.Disconnect power.

i. Replace cover plate (2) and re-install all wires from duct furnace terminal “43”.

7. After adjustment, move the field installed manual shut-off valve to the “OFF” position and replace the 1/8" pipe plug.

8. After the plug is in place, move the field installed manual shut-off valve to the “ON” position and recheck pipe plugs for gas leaks with soap solution.

figure 12.2 - checking manifold Pressure with “u” tube manometer main Burner adjustment

The gas pressure regulator (integral to the combination gas control) is adjusted at the factory for average gas conditions.

It is important that gas be supplied to the duct furnace in accordance with the input rating on the serial plate. Actual input should be checked and necessary adjustments made after the duct furnace is installed. Over-firing, a result of too high an input, reduces the life of the appliance and increases maintenance. Under no circumstances should the input exceed that shown on the serial plate.

Measuring the manifold pressure is done at the tee in the manifold (See Figure 12.2).

manifold tee

start-uP Procedure

figure 13.1 - maxitrol modulating valve adjustments air shutter adjustment

Proper operation provides a soft blue flame with a well-defined inner core. A lack of primary air will reveal soft yellow-tipped flames. Excess primary air produces short, well-defined flames with a tendency to lift off the burner ports. For both natural and propane gas, the air shutters can be adjusted to control the burner flame height. The air shutters can be accessed by reaching behind the manifold tee shown in Figure 12.2. The larger models may require the removal of the manifold (see

Manifold Assembly Removal).

natural Gas flame control

Control of burner flames on duct furnaces utilizing natural gas is achieved by resetting the primary air shutters (See Figure

53.2) to either increase or decrease primary combustion air.

Prior to flame adjustment, operate duct furnace for about fifteen minutes. The main burner flame can be viewed after loosening and pushing aside the gas designation disc on the side of the burner box.

To increase primary air, loosen the air shutter set screws and move the air shutters closer to the manifold until the yellowtipped flames disappear. (See Figure 53.2 for air shutter and heat exchanger support locations.) To decrease primary air, move the air shutters away from the manifold until flames no longer lift from burner ports, but being careful not to cause yellow tipping. Retighten set screws after adjustment.

Propane Gas flame control

An optimum flame will show a slight yellow tip. Prior to flame adjustment, operate furnace for at least fifteen minutes. Loosen air shutter set screws and move the air shutters away from the manifold to reduce the primary air until the yellow flame tips appear. Then increase the primary air until yellow tips diminish and a clean blue flame with a well defined inner cone appears.

Blower adjustments

If blower fan speed changes are required, adjust motor sheave as follows:

1. Refer to page 34 to determine correct blower speed according to job requirements, then proceed with steps 2 through 8.

2. Loosen motor base and take belt off of motor sheave.

3. Loosen set screw on outer side of adjustable motor sheave.

figure 14.1 - motor sheave adjustment

Set Screw

Adjustable Half of Sheave

4. Turn outer side of motor sheave clockwise until motor sheave is fully closed.

5. From fully closed position, turn outer side of motor sheave counterclockwise until the proper number of turns open are achieved.

6. Retighten motor sheave set screw, replace belt and retighten motor base. Motor base should be shifted for proper belt tension which is 3/4" deflection with about 5 lbs. of force.

figure 14.2 - Belt tension adjustment lubrication recommendations

The blower can be provided with either spider or pillow block bearings. Spider bearings are permanently lubricated and do not require lubrication. Pillow block bearings are shipped greased from the factory but will require lubrication. The bearings should be checked and lubricated before each heating season but a more frequent lubrication schedule may be required based on the environment in which the unit is installed, and the frequency of the equipment operation. Shell Alvania #2 lubricant is recommended.

damper linkage adjustment

If the unit is provided with a return air damper, to prevent shipping damage, the return air damper linkage is disconnected and the damper closed. Before operating the unit, the fresh and return air dampers must be connected. This is accomplished by the following:

1. The damper actuator should be de-energized and the fresh air damper in a fully closed position.

2. Open the return air damper in a fully open position.

3. Slide the connecting rod into the ball joint on the blade arm with the return air damper fully open. See Figure 14.3.

4. Tighten the 5/16" hex head screw on the ball joint.

start-uP Procedure

control operating sequence

All weatherproof units are supplied with intermittent pilot ignition systems. These systems are offered with 100% shut-off with continuous retry for operation on natural gas and 100% shut-off with lockout for units operating on propane gas. On all systems, both the main burner and pilot burner are turned off

100% when the thermostat is satisfied.

For natural gas units, the ignition controller is 100% shut-off with continuous retry. On a call for heat, the system will attempt to light the pilot for 70 seconds. If the pilot is not sensed for any reason, the ignition control will wait for approximately six minutes with the combination gas control closed and no spark.

After six minutes, the cycle will begin again. After three cycles, some ignition controllers lockout for approximately one hour before the cycle begins again. This will continue indefinitely until the pilot flame is sensed or power is interrupted to the system.

For propane gas units, the ignition controller is 100% shutoff with lockout. On a call for heat, the system will attempt to light the pilot for 70 seconds. If the pilot is not sensed for any reason, the ignition control will lockout, the pilot gas valve shut off and the sparking discontinued. The system will not attempt to relight until power has been interrupted to the controls and the controls are reset via the thermostat.

note: Factory Installed Options (see page 18) could change the listed sequence of operation based on their function. The descriptions given are for the basic unit.

single-stage Gas controls

Utilizes a single-stage combination gas control, an ignition control, and a single-stage low voltage thermostat.

1. The thermostat calls for heat.➀

2. The pilot valve opens and the spark ignitor sparks in an attempt to light the pilot.

3. Once the pilot is lit, the flame sensor proves the pilot and stops the spark ignitor from sparking.

4. The main gas valve is opened and the main burner is lit to

100% full fire.

5. The time delay relay starts the blower after 30 to 45 seconds.

6. The unit continues to operate until the thermostat is satisfied, at which time both the main and pilot valves close 100%.

7. The time delay relay stops the blower after 30 to 45 seconds.

two-stage Gas controls

9. The unit continues to operate until the low stage thermostat is satisfied, at which time both the main and pilot valves close 100%.

10. The time delay relay stops the blower after 30 to 45 seconds.

electronic modulating Gas controls single furnace - model sizes 75-400

Utilizes an electronic modulating/regulating gas control, combination gas valve, an ignition control, modulating amplifier, and either a modulating room thermostat or modulating duct thermostat with remote temperature set point adjuster. The thermostat controls can modulate the gas flow between 40% through 100% full fire.

When the thermostat is satisfied, the amplifier cuts power to the combination gas valve which prevents gas flow to both the main and pilot burners.

When duct sensing is utilized, a room override thermostat can be added. When calling for heat, the room override thermostat provides full fire operation until the space temperature is satisfied.

Control is then returned to the duct sensing control. In this situation, either the duct sensor or the room override thermostat can call for heat.

1. The thermostat calls for heat. ➀

2. The pilot valve opens and the spark ignitor sparks in an attempt to light the pilot.

3. Once the pilot is lit, the flame sensor proves the pilot and stops the spark ignitor from sparking.

4. The main gas valve is opened and the main burner is lit to

100% full fire.

5. The time delay relay starts the blower after 30 to 45 seconds.

6. The modulating gas valve can be controlled by either an electronic modulating room or duct thermostat. The thermostat can modulate the firing rate between 40% through 100% full fire. The call for heat is created by a resistance signal (8000 to 12000 ohms) in the thermostat.

The amplifier converts this resistance into a DC voltage

(0 to 12 volts DC with 0 volts high fire and 12 volts low fire). The output voltage is applied to the modulating gas valve to control the gas flow to the main burner. As the temperature drops, the voltage drops causing the modulating valve to open further. If the discharge air temperature increases, the voltage increases causing the modulating valve to close allowing less gas flow to the main burner. For further information regarding the operation of the electronic modulating system, consult the literature provided with the unit.

7. The unit continues to operate in this manner until the thermostat is satisfied, at which time both the main and pilot valves close 100%.

8. The time delay relay stops the blower after 30 to 45 seconds.

Utilizes a two-stage combination gas control, an ignition control, and a two-stage low voltage thermostat. The unit fires at 50% fire on low stage and 100% fire on high stage.

1. The thermostat calls for low stage heat.➀

2. The pilot valve opens and the spark ignitor sparks in an attempt to light the pilot.

3. Once the pilot is lit, the flame sensor proves the pilot and stops the spark ignitor from sparking.

4. The main gas valve is opened and the main burner is lit to

50% fire.

5. The time delay relay starts the blower after 30 to 45 seconds.

6. If the temperature at the thermostat continues to fall, the thermostat will call for high stage heat.

7. The main gas valve is opened completely and the main burner is lit to 100% full fire.

8. The unit continues to operate until the high stage of the thermostat is satisfied, at which time the main valve closes to 50% fire.

electronic modulating Gas controls two & three furnaces - model sizes 500-960

One Master furnace is provided with up to two Slave furnaces that utilize electronic modulating/regulating gas controls, combination gas valves, ignition controls, one multiple furnace modulating amplifier, and either a modulating room thermostat or modulating duct thermostat with remote temperature adjustment. The thermostat controls can modulate the gas flow of all the furnaces between 40% through 100% full fire. The amplifier sends a signal to all of the gas valves so that they modulate at the same percentage. When the thermostat is satisfied, the amplifier cuts power to the combination gas valves which prevents gas flow to both the main and pilot burners.

➀

For Models HBP/HCP/HDP/HPP after the thermostat calls for heat, the power exhauster relay is energized starting the power exhauster motor. Once the motor has reached full speed, the power exhauster centrifugal switch closes energizing the gas control circuit.

start-uP Procedure

When duct sensing is utilized, a room override thermostat can be added. When calling for heat, the room override thermostat provides full fire operation until the space temperature is satisfied. Control is then returned to the duct sensing control.

In this situation, either the duct sensor or the room override thermostat can call for heat.

The sequence of operation for Electronic Modulating Gas

Controls - Two & Three Furnaces is the same as Electronic

Modulating Gas Controls - Single Furnace.

electronic modulating Gas controls -

Building management control

(0-10vdc or 4-20 ma signal)

Utilizes an electronic modulating/regulating gas control, combination gas valve, an ignition control, modulating signal conditioner, and an inverted (0 Vdc or 4mA being high fire and

10 Vdc or 20 mA being low fire) 0-10Vdc or 4-20 mA input signal provided by a Building Management System (BMS).

The signal conditioner can modulate the gas flow between

40% through 100% full fire. When the BMS thermostat (field supplied) is satisfied, the BMS heat contact (field supplied) opens to cut power to the combination gas valve which prevents gas flow to both the main and pilot burners.

1. The BMS thermostat (field supplied) calls for heat and closes the BMS heat contact (field supplied). ➀

2. The pilot valve opens and the spark ignitor sparks in an attempt to light the pilot.

3. Once the pilot is lit, the flame sensor proves the pilot and stops the spark ignitor from sparking.

4. The main gas valve is opened and the main burner is lit to

100% full fire.

5. The time delay relay starts the blower after 30 to 45 seconds.

6. The modulating gas valve is controlled the BMS thermostat. The thermostat can modulate the firing rate between 40% through 100% full fire by modulating the input signal between either 0-10Vdc or 4-20 mA (The signal conditioner can accept a 0-10 Vdc signal when all the dip switches are in the “OFF” position and 4-20 mA signal when all the dip switches are in the “ON” position).

The signal conditioner converts the input signal into a DC voltage (0 to 12 volts DC with 0 volts high fire and 12 volts low fire). The output voltage is applied to the modulating gas valve to control the gas flow to the main burner. As the temperature drops, the voltage drops causing the modulating valve to open further.

If the discharge air temperature increases, the voltage increases causing the modulating valve to close allowing less gas flow to the main burner. For further information regarding the operation of the electronic modulating system, consult the literature provided with the unit.

7. The unit continues to operate in this manner until the thermostat is satisfied, at which time the BMS heat contact opens resulting in both the main and pilot valves closing

100%. (If the unit was not provided with a time delay relay, the blower stops at this time.)

8. The time delay relay stops the blower after 30 to 45 seconds.

variable air movement applications

Units may be supplied with variable frequency drives for applications where variable air volume is required. The minimum air flow may be varied between 30 and 100% of the full speed air flow depending on the controls selection of the unit. Due to the extra restrictions of the controller all selections must be performed with the AccuSpec configuration software.

Within AccuSpec, three variable frequency drive speed control changeover options are variable:

1. Two speed which may be controlled by a manual high/low switch which may be factory mounted on the control panel or shipped loose for field installation or by exhaust fan interlocks.

2. Floating building pressure sensing which utilizes a photohelic pressure controller to adjust the building pressure by varying the amount of makeup air supplied to the space.

3. Building management control which allows for an external signal of 0-10VDC of 4-20mA to adjust the unit airflow.

Additionally, when the unit is equipped with a two-speed motor, the allowable minimum CFM of the HFG/HFP duct furnace can be 66% of the minimum listed CFM in Table 26.1 if the unit is applied as follows:

1. The unit is provided with 2-stage, mechanical modulation, or electronic modulating gas controls. (see Model

Identification).

2. The unit is provided with a factory installed discharge air controller.

3. The system does not include a room thermostat.

The factory installed discharge air thermostat will prevent the unit from firing above the allowable 100°F rise when the unit is at or above the minimum CFM by monitoring the discharge air and going to low fire. A room thermostat, because it is located remote from the unit, could cause the unit to over-fire.

➀

For Models HBP/HCP/HDP/HPP after the thermostat calls for heat, the power exhauster relay is energized starting the power exhauster motor. Once the motor has reached full speed, the power exhauster centrifugal switch closes energizing the gas control circuit.

(DWDI) blower wheel so both sides of the blower must be free from obstructions for proper operation. For Right Hand units

(Digit 9 = R), during operation the blower wheel should rotate in the clockwise direction when viewed from the service side of the unit. For Left Hand units (Digit 9 = L), during operation the blower wheel should rotate in the counterclockwise direction when viewed from the service side of the unit. If necessary, interchange supply power wiring to reverse blower rotation.

Two-position Damper Actuator: A two-position damper actuator is provided with Air Control options DA, EA, EQ, and FA (Digits

20 & 21). The two-position damper actuator provides open/ closed operation of the fresh air damper. When the damper is energized, the fresh air damper is opened to 100% outside air in 75 seconds (For units with a two-position damper limiter, the outside air percentage would be the set by the damper limiter.

See Two-Position Damper Limiter below). All two-position damper actuators are spring return, so when the damper is de-energized, the fresh air damper will spring closed. All twoposition dampers include auxiliary switches (one normally open and one normally closed) that reverse when the damper actuator is at 85° rotation (adjustable).

Two-Position Damper Limiter: The two-position damper limiter is factory set to prevent the outside air damper from opening

100%. The outside air percentage and the actuator end switch is set based on the unit order.

(24) Pillow Block Bearings – (oPt)

The blower bearings are factory installed in the blower section.

The blower can be provided with either spider or pillow block bearings. Spider bearings are permanently lubricated and do not require lubrication. Pillow block bearings are shipped non-greased from the factory and require lubrication before start-up. For lubrication recommendations, see Lubrication

Recommendations.

(25) Blower motor – (std)

The blower motor is factory installed in the blower section. The blower motor can be provided in a variety of supply voltages, frame types, and motor horsepowers. Refer to the model nomenclature to determine the type of motor provided. The blower motor is supplied with an adjustable sheave that can be used to increase/decrease the blower RPM. For instructions on changing the blower RPM, refer to Blower Adjustments.

(26) filters – (oPt)

When filters are supplied with the unit, a rack and the filters are factory installed in the blower section. The unit can be supplied with 1" or 2" permanent filters, 2" FARR® Aeropleat or 2" FARR® 30/30 filters. For filter replacement, refer to

Maintainance.

(27) fresh air damper – (oPt)

When a fresh air damper is supplied with the unit, the damper

5-572.7

Field adjustment of the two-position damper limiter is accomplished by the following:

1. Determine the amount of damper rotation required

(Percentage of outside air).

2. Locate the angle of rotation limiter on the actuator so that its edge lines up with the degree graduation on the actuator face which corresponds with the required rotation. (See Figure

22.1 which is shown at 50% rotation limit.)

3. Find the appropriate cross-hair location through the slot of the limiter. This is the screw mounting location.

4. Pierce through the label material to allow easy fastening of the retaining screw.

5. Position the limiter back to the desired position, making sure the locating “teeth” on the limiter are engaged into the locating holes on the actuator.

6. Fasten the limiter to the actuator using the self tapping screw provided.

7. Test the damper rotation either manually with the manual crank or apply power and if required, a control signal.

Re-adjust if necessary.

Modulating Damper Actuator: A modulating damper actuator is provided with Air Control options GA, GB, GC, GD, GE,

GF, GG, GH, GJ, Gk, GM, and GN (Digits 20 & 21). The modulating damper actuator provides incremental operation of the fresh air damper (The return air damper is controlled by the fresh air damper position). Full 90° rotation of the modulating actuator requires 150 seconds. All modulating damper actuators operate using a 0-10 Vdc input signal (Air Control GB utilizes a resistor to convert from a 4-20 mA to 0-10 Vdc) from a damper controller. All modulating damper actuators are spring return, so when the damper is de-energized, the fresh air damper will spring closed.

Floating Damper Actuator: A floating damper actuator is provided with Air Control option HP (Digits 20 & 21). The floating damper actuator provides forward and reversing damper operation in response to contact closures from the space pressure controller. When the space pressure is above the desired set point, a high pressure contact on the space pressure controller energizes the damper to drive the fresh air damper closed. When the space pressure is below the desired set point, a low pressure contact on the space pressure controller energizes the damper to drive the fresh air damper open. When the space pressure is between the high and low set points, the damper “floats” at the fresh air percentage that satisfied the space pressure controller. Full 90° rotation of the floating actuator requires 150 seconds. For additional information on the space pressure controller, refer to Literature

5-585.

COOLING MODE

When the space thermostat calls for cooling, the system operates as follows:

Outdoor Air Enthalpy is Below Changeover Set Point

1. The outdoor air damper is proportioned open (and the return

air damper is proportioned closed) to maintain between 50°F

and 56°F at the mixed temperature air sensor.

2. During economizer operation, mechanical cooling is operated

by the second stage of the cooling on the space thermostat.

Outdoor Air Enthalpy is Above Changeover Set Point

1. The outdoor air damper is closed to its minimum position.

2. A call for cooling from the space thermostat brings on

mechanical cooling.

The enthalpy controller is used in conjunction with the Enthalpy

Sensor (Item 28) and a mixed air temperature sensor (not shown). The mixed air temperature sensor is factory installed in the blower section to sense the combined temperature of the fresh and return air streams. The sensor is non-adjustable and when in the free cooling mode, modulates the dampers to maintain between 50°F and 56°F at the sensor.

The enthalpy controller contains a minimum position adjustment and an enthalpy changeover set point that must be field set.

figure 22.2 - enthalpy controller

The damper actuator is designed to “float” and therefore it is not spring return. When the unit is de-energized under normal operation, the fresh air damper is closed by a relay contact closure which electrically drives the damper closed. If the supply power to the unit is interrupted before the damper actuator can drive closed, the fresh air damper will remain open. The damper can be manually closed through the use of the manual override switch on the floating damper actuator.

Minimum Position Adjustment:

The minimum position adjustment keeps the outdoor air damper from closing completely during system operation to provide ventilation in both the heating and cooling modes.

To set the minimum position adjustment:

1. Disconnect mixed air sensor from terminals T and T1 on the

enthalpy controller.

2. Make sure the factory installed jumper is in place across terminals P and P1.

3. Connect 24 Vac across terminals TR and TR1.

4. Adjust the minimum position adjustor with a screwdriver for

the desired minimum position.

(

31) enthalpy controller – (oPt)

An enthalpy controller is provided with Air Control option GJ

(Digits 20 & 21) and factory installed in the blower section.

The purpose of the enthalpy controller is to use outside air for cooling, whenever possible, to reduce compressor operation of the mechanical cooling system. The economizer functions as a true first stage of cooling and provides maximum fuel economy during the cooling cycle.

Outdoor Enthalpy Changeover Set Point

The outdoor enthalpy changeover set point returns the outdoor air damper to the minimum position when the enthalpy rises above its set point. Enthalpy set point scale markings, located on the enthalpy controller, are A, B, C, and D. See Figure 23.1 for the corresponding control point. The factory installed 620ohm jumper placed across terminals S

R

and + is required for proper operation and should not be removed. Refer to suppliers literature supplied with the unit for additional information.

HEATING and VENTILATING MODE

When the space thermostat calls for heat or it is in the fan

ON position without a call for cooling (ventilation mode), the economizer is automatically locked out. It holds the outdoor air damper at the minimum position setting.

22

(32) damper to damper linkage – (oPt)

Units with fresh and return air dampers include a damper actuator that controls the fresh air damper. The return air damper position is controlled by the fresh air damper through the connecting rod. For adjustment, refer to Damper Linkage

Adjustment.

The convenience outlet is factory installed in the blower section for providing power for 115V service equipment (trouble light, power tools, etc.). The 115V ground fault circuit interrupter

(GFCI) is rated for 15 amps and includes test and reset switches. A separate field supplied 115V/1Ph power supply must be routed through the electrical section wall into the back of the convenience outlet junction box.

(38) Blower door switch – (oPt)

The blower door switch is factory installed inside the blower section door on the access side of the unit. When the blower section door is removed, the momentary switch is released and interrupts power to the low voltage circuit. For single phase units 1-1/2 Hp and less, the door switch de-energizes a relay that controls blower motor operation. For three phase units and single phase units 2 Hp and greater, the door switch deenergizes the motor starter that controls blower motor operation.

For servicing, the switch is equipped with an override position that can be manually pulled out to override the switch. See

Figure 23.2

figure 23.2 - Blower door switch with manual override

(

33) return air damper – (oPt)

When a return air damper is supplied with the unit, the damper is factory installed in the blower section. The return air damper is used as a air balancing damper so low leak, Class III leakage resistance (less than 40 CFM/ft2 at 1" W.C.) dampers with selfcompensating stainless steel side seals and santoprene blade seals are used.

(34) Proportional temperature controller sensor – (oPt)

A proportional temperature controller sensor is provided with Air

Control options GF, GG, GH, Gk, GM, or GN (Digits 20 & 21) and factory installed in the blower section. The sensor provides the mixed air temperature signal to the A350P Proportional

Temperature Controller which is mounted in the electrical section.

(

35) motor and Blower vibration isolation – (oPt)

The motor vibration isolation is factory installed in the blower section below the blower support bracket. The four (4)

13/32" neoprene vibration mount grommet provides isolation of the blower housing and motor from the blower support channels. The blower vibration isolation is factory installed in the blower section between blower discharge and the blower duct connection. The blower duct connection is not rigidly mechanically fastened and the 1/4'' thick gasketing around the duct transition provides vibration isolation.

(36) Blower support – (std)

The blower supports are factory installed in the blower section.

The blower supports are used to rigidly support the weight of the blower and motor during operation and shipping.

(37) convenience outlet – (oPt)

WARNING

Do not perform service on the convenience outlet without

disconnecting its power supply. The convenience outlet power

supply is separate from main power supply to the unit. When

the main disconnect switch is de-energized, the convenience

outlet power supply remains energized.

(

39) dirty filter switch – (oPt)

The dirty filter pressure switch is factory installed in the electrical section. The dirty filter pressure switch monitors the pressure differential between the two sides of the filters. When the filters become dirty, the differential pressure increases and trips the pressure switch which energizes a light on the remote monitoring panel. The pressure differential switch must be field set because setting the switch requires the blower to be in operation and the ductwork to be installed.

setting the dirty filter switch

The range of the dirty filter pressure switch is adjustable between 0.17" to 5.0" W.C.

1. Ensure that the unit filters are clean. Clean or replace if necessary.

2. Connect the leads of a continuity tester to the NO and C terminals of the dirty filter pressure switch. See Figure 24.1

3. Set the thermostat so that there is a call for heat. This should fire the burner and the blower should start.

4. Turn the set screw of the pressure switch clockwise until it stops. This will set the pressure at 5.0" W.C. and the continuity tester should be sensing an open circuit.

5. Begin turning the screw counterclockwise until the continuity tester senses a closed circuit. This determines the base pressure of the system.

6. Turn the screw clockwise until the continuity tester senses an open circuit and then one additional full turn (This is approximately 0.25" W.C.) This will allow for the increase in static pressure due to dirty filters.

(42) Proportional temperature controller – (oPt)

A proportional temperature controller is provided with Air

Control options GF, GG, GH, Gk, GM, or GN (Digits 20 & 21) and factory installed in the electrical section. The controller compares the mixed air temperature set point and the mixed air temperature from the Proportional Temperature Controller

Sensor. The controller sends a 2-10 Vdc signal to the modulating damper actuator in order to maintain the set point.

The controller includes a set point dial that must be field set to the desired mixed air temperature (typically 55°F).

figure 24.3 - Proportional temperature controller

(40) motor starter – (oPt)

The motor starter is factory installed in the electrical section. A motor starter is required for all three phase motors and single phase motors 2 Hp and greater. The motor starter current set point dial is factory set to the motor full load amp draw listed on the motor nameplate.

The overload module of the motor starter is designed to trip to protect the motor from exceeding the nameplate amps. If the motor exceeds the amp draw on the current set point dial, the trip condition is indicated by a red color in the trip indicator window. The motor starter can be placed in the automatic or manual reset positions. Automatic reset is accomplished by depressing the “RESET” button and turning the button 1/4 turn.

When in the automatic reset position, if the overload module trips, the module will reset itself once the overload relay has cooled. In the manual reset position, if the overload module trips, the “RESET” button must be depressed before the blower can operate.

The contractor module includes one (1) normally open auxiliary contact. The contact rating is 10 amps.

If the factory installed motor starter option was not ordered with a unit that has a three phase motor or single phase motor 2 Hp or greater, a motor starter must be field supplied and installed.

(40) variable frequency drive – (oPt)

The VFD controller adjusts the motor RPM to vary the unit airflow. The minimum air flow may be varied between 30 and 100% of the full speed airflow depending on the controls selection of the unit. The control changeover options are two speed, floating building pressure sensing, and building management control.

(45) service switches – (oPt)

The service switches are factory installed in the electrical section. The service switches allow for service personnel to independently test operation of the damper, blower, and furnace without using jumper wires. The switches override the remote monitoring panel and/or thermostats to energize each component directly. All switches need to be reset to the “OFF” position after testing otherwise the components will remain energized (See Figure 25.1).

(41) mild temperature thermostat – (oPt)

The mild temperature thermostat is factory installed in the electrical section. The mild temperature thermostat is designed to lockout the burner during mild weather conditions which prevents the burner from cycling. The thermostat must be field

5-572.7

(46) electronic modulation amplifier – (oPt)

An electronic modulation amplifier is provided factory installed in the duct furnace electrical junction box when the unit is equipped with Electronic Modulating Gas Controls (Digit 12 =

4 or 5). The amplifier processes the thermostat temperature and set point signals to modulate the firing rate between 40% to 100% full fire. For additional information, refer to Control

Operating Sequence.

oPtions - factory installed figure 25.1 - service switches

(52) Burner Box – (std)

The burner box is located in the duct furnace section and contains the burner and pilot assembly. The burner box includes an access panel for removal of the burner for inspection and servicing.

(47) electronic modulating Gas valve – (oPt)

An electronic modulating gas valve is provided factory installed in the duct furnace gas train when the unit is equipped with

Electronic Modulating Gas Controls (Digit 12 = 4, 5, 6, 7, or 8).

The gas valve modulates the firing rate between 40% to 100% full fire based on the input signal from the Electronic Modulation

Amplifier or Signal Conditioner. For additional information, refer to Control Operating Sequence.

(48) air flow Proving switch – (oPt)

The air flow proving switch is factory installed in the duct furnace electrical junction box. The air flow proving switch monitors the pressure differential between the duct furnace and the atmosphere. The purpose of the air flow proving switch is to cut power to the gas controls if a positive pressure is not measured by the switch. This could be caused by a lack of air movement through the heat exchanger (Refer to Figure 24.1).

(53) direct drive damper actuator – (oPt)

The direct drive damper actuator is factory installed in the downturn plenum section. The actuator controls the position of the supply air damper and can only be used on 100% make-up air units. All damper actuators are low voltage (24V). For Right

Hand units (Digit 9 = R), during operation the actuator should rotate in the counterclockwise direction when viewed from the service side of the unit. For Left Hand units (Digit 9 = L), during operation the actuator should rotate in the clockwise direction when viewed from the service side of the unit. When the damper is energized, the fresh air damper is opened to 100% outside air in 75 seconds. All two-position damper actuators are spring return, so when the damper is de-energized, the fresh air damper will spring closed. All two-position dampers include auxiliary switches (one normally open and one normally closed) that reverse when the damper actuator is at 85° rotation (adjustable).

NOTE: The air flow proving switch will prevent any heat exchanger warm-up because the gas controls can not be energized until air flow is proven.

(54) discharge damper – (oPt)

When a discharge air damper is supplied with the unit, the damper is factory installed in the downturn plenum section. The discharge air damper is used an outside air shut-off damper so ultra low leak, Class II leakage resistance (less than 10 CFM/ft2 at 1" W.C.) dampers with self-compensating stainless steel side seals and santoprene and galvanized steel blade seals are used.

setting the air flow Proving switch

The range of the air flow proving switch is adjustable between

0.17" to 5.0" W.C.

1. Set the thermostat so that there is a call for heat. This should start the blower and then the burner ignition sequence.

2. Turn the set screw of the pressure switch clockwise until it stops. This will set the pressure at 5.0" W.C.

3. Turn the screw counter-clockwise until the gas controls light and then one additional full turn. (This is approximately

0.25" W.C.) This will allow for dirty filters or any other slight static pressure increases in the system.

(not shown) circuit analyzer – (oPt)

The circuit analyzer is factory installed on the door of the electrical section. The circuit analyzer is used to quickly assist service personnel in troubleshooting by monitoring the unit firing sequence and vital operating steps. Lights will come on as a point of electrical operation is passed and proven. If any light is not lit, that is the point where failure occurred.

(49) High limit switch

Automatic – (STD)

The automatic reset high limit switch is factory installed in the duct furnace electrical junction box. If the limit temperature is exceeded, the gas controls are de-energized until the switch is cooled.

figure 25.2 - circuit analyzer

Circuit analyzer tagging will vary based on the unit ordered.

Circuit analyzer shown is for reference only.

Manual – (OPT)

The manual reset high limit switch is factory installed in place of the standard automatic reset high limit switch located in the duct furnace electrical junction box. In case of a failure of the blower motor, blockage of the inlet air, etc., the manual reset switch prevents the unit from cycling on the high limit. If the limit temperature is exceeded, a service person must inspect the unit for the cause of the high discharge temperature, take corrective action, and then reset the switch.

(50) supply air fire stat – (oPt)

The supply air fire stat is factory installed in the duct furnace electrical junction box with the sensor in the discharge air stream.

In case of elevated temperatures in the supply air stream, the manual reset switch shuts down the entire unit. If the limit temperature is exceeded, a service person must inspect the unit for the cause of the high discharge temperature, take corrective action, and then reset the switch.

(51) main Gas valve – (std)

The main gas valve is factory installed in the duct furnace gas train. The main gas valve provides the pilot, regulator, main gas, and manual shutoff functions. For additional information, see the supplier literature included with the unit.

unit selection

selection Procedure

In order to properly select an indirect-fired heating, ventilating, cooling or make-up air unit, it is necessary to have the following basic information.

1. required air handling capacity (cfm).

The air capacity of the unit is usually determined by the ventilation air requirements, exhaust load of the building, infiltration losses, or the air turns/changes of the space.

2. outdoor and indoor design temperature.

The outdoor design temperature is determined by using the ASHRAE Guide design temperatures for the city where the equipment is to be installed. For heating and ventilating units, the desired room temperature would be used as the indoor design temperature. In the case of 100% make-up air units, the discharge air temperature should be at least equal to the temperature of the air being exhausted.

3. required heating output capacity (Btu/Hr).

The heating output capacity of the unit is determined by using the formula:

BTU/HR = CFM x Temp. Rise (°F) x 1.08

4. external static pressure to unit.

The external static pressure (E.S.P.) is determined using the ASHRAE Guide for duct losses, or may be provided by the design engineer.

5. unit configuration with options and accessories

(rainhood, filters, dampers, or evaporative cooler).

The unit configuration is determined by the location where the unit is to be installed. The critical options and accessories are those that add internal static pressure

(I.S.P.) to the unit. Once these items are determined, the pressure drop curves would be used to calculate the total pressure drop (T.S.P.)

Total Static Pressure = Internal + External Static Pressure

6. Heat exchanger material.

The heat exchanger type is determined by the application.

The standard heat exchanger material is aluminized steel. A 409 stainless steel heat exchanger and burner is recommended when the unit is installed downstream of a cooling coil or evaporative cooler, and when the combined entering/return air to the unit is below 40°F.

7. type of fuel.

Either natural or propane gas determined by the design engineer.

8. Gas control staging method.

Either single stage, two stage, mechanical modulation, or electronic modulation determined by the design engineer.

9. main power supply voltage to unit.

10. altitude at which unit is to be installed.

With this information a basic unit can be selected as shown in the following example.

selection example conditions

Select an indirect-fired, 100% make-up air unit to meet the following conditions:

1. CFM at sea level = 5,000 cfm

2. Outdoor design temp. = 10°F

Indoor design temp. = 70°F

3. Heating output capacity =

5000 cfm x (70°F -10°F) x 1.08 = 324,000 Btu/Hr

4. External Static Pressure = 0.65

5. The Gravity Vented unit with the controls on the Right

Hand Side is to be provided with the following:

2" Permanent Filters, a Rainhood with Fresh Air Damper,

and a Downturn.

6. Heat exchanger and burner = 409 Stainless Steel.

7. Gas Type = Natural

8. Gas Controls = Electronic Modulating with Duct Sensing.

9. Supply Voltage: 460V/60Hz/3Ph

10. Altitude: 1000 feet

With the information listed above, the basic model, using the

Model Nomenclature shown on page 59, can be selected as shown in the following example:

1. determine the model configuration and venting:

The Model Configuration is determined by the required sections of the unit (Blower and Downturn) and the venting style (Gravity) that are obtained from item #5. Using the

Model Nomenclature on page 59, the Model Configuration and Venting = HDG.

2. determine the furnace input rating (mBH):

Using the Heating output capacity, the Furnace Input

Rating is determined from Table 27.1. The closest model to 324,000 Btu/Hr output has an Btu/Hr Input rating of

400,000 Btu/Hr so the Furnace Input Rating = 400.

3. determine the Heat exchanger/Burner/drip Pan material:

From item #2 listed above, the Heat Exchanger and Burner required are 409 Stainless Steel. Because the Drip Pan material is not specified, the standard Aluminized Steel drip pan will be used. Thus, the Heat Exchanger/Burner/Drip

Pan Material = S.

4. determine the development sequence:

From item #8 listed above, the modulating gas controls result in the Development Sequence = M.

5. determine the access side:

From item #5 listed above, the Right Hand Gas controls result in the Access Side = R.

6. determine the air temperature rise:

From item #2 listed above, the Air Temperature Rise is

60°F (70°F - 10°F). However, using the output capacity of the HDG400 @ 5000 cfm, the resulting temperature rise is

59.3°F (320,000/(5000 x 1.08). Since the rise is less than

60°F, the Air Temperature Rise = L.

7. determine the Gas type:

From item #7 listed above, the Natural Gas results in the

Gas Type = N.

8. determine the Gas valve:

From item #8 listed above, the Electronic Modulating with

Duct Sensing results in the Gas Valve = 4.

9. determine the additional safety switches:

Since no additional safety switches were specified, the

Additional Safety Switches = 0.

unit selection

10. determine the supply voltage:

From item #9 listed above, the 460V/60Hz/3Ph results in the Supply Voltage = F.

11. determine the transformer:

With the selected Unit Type = HDG, the Transformer = 2.

12. determine the Blower size and Bearing type:

Using Table 27.1, the Model Size 400 has three available blowers for which the performance tables are shown on page 32. Since all of the blower performance tables can provide the required 5000 cfm, the total static pressure for each blower performance curve must be determined.

A) The Pressure Drop of an option or accessory is determined by entering the right of the table at the desired cfm and reading across the table until the cfm intersects the desired item. For this example, in table

30.1 the 2” Permanent Filter is used. At the point of intersection, read across the table to the right and read the pressure drop, in inches of water column for the filters. For this example, the pressure drop is 0.06” W.C.

This method is used to determine the pressure drop for the other options and accessories. As a result:

For the Model Size 400 with Digit 16 = E,F,G, or H:

2” Permanent Filters:

Rainhood:

Downturn:

0.06” W.C.

0.11” W.C.

0.07” W.C.

Internal Static Pressure Drops 0.24” W.C.

The Total Static Pressure for the system is determined by Internal Static + External Static = Total Static Pressure

For this example 0.24” + 0.65” = 0.89” W.C. T.S.P.

From page 30, for the Model Size 400 with Digit 16 = I, J, or k:

2” Permanent Filters:

Rainhood:

0.04” W.C.

0.11” W.C.

Downturn: 0.07” W.C.

Internal Static Pressure Drops 0.22” W.C.

The Total Static Pressure for the system is determined by Internal Static + External Static = Total Static Pressure

For this example 0.22” + 0.65” = 0.87” W.C. T.S.P.

B) Using the total static pressure (T.S.P.) calculated in step

12a, use blower performance tables for the Model Size

400 (Tables 32.1).

Using Table 32.1, enter the table at the required 5000 cfm for E.F. blowers, and follow the cfm line to the right until it intersects with the T.S.P. line of 0.75” W.C. which is shown at the top of the table. At the point of intersection of these two columns, read the required horsepower and blower rpm. Repeat this process for

1.00” T.S.P and iterate to determine the BHP and rpm for 0.89” W.C. For this example the horsepower is 5 and the blower rpm is 1280.

IMPORTANT

When selecting the required motor horsepower, the horsepower must always be read off the curve to the right of the data point determined from the intersection point of the cfm and T.S.P. lines.

Following this procedure for G,H blowers (Using 5000 cfm and 0.89” W.C. T.S.P), the horsepower is 5 hp and

920 rpm. Following this procedure for I,J,k blowers

(Using 5000 cfm and 0.87” W.C. T.S.P), the horsepower is 3 hp and 700 rpm. Although I,J,H blowers results in a

3 hp motor, this blower requires the use of the extended cabinet length. As a result, for purposes of this selection example G,H blowers will be used.

Since the Bearing Type was not specified, the standard spider bearings will be used. Thus, using Table 32.1 with spider bearings, the Blower Size and Bearing Type = G.

13. determine the motor Horsepower:

The motor horsepower determined in step 12 was a 3 Hp.

Since the supply voltage is 460V/60Hz/3Ph, a motor starter will need to be provided either with the unit or by others.

For purposes of this selection, a motor starter by others will be used so the Motor Horsepower = G.

14. determine the motor type:

The motor type was not specified so for purposes of this selection the standard open drip proof motor will be used so the Motor Type = 1.

15. determine the sheave arrangement:

To establish the Sheave Arrangement, the motor frame size must be determined. The Motor Data tables on pages 38 to

42 contain the motor frame size.

A) Using the Supply Voltage (460V/60Hz/3Ph), enter the correct Motor Data table (Table 41.1). Using Model

Nomenclature Digits 17 and 18 (G1) determined in steps

13 and 14, find the motor frame size (182T).

B) Using the Motor Frame Size enter the Sheave Selection table for the selected blower determined by step 13

(Table 35.2). Using the rpm calculated in step 12 (920 rpm), select the sheave range that contains the required rpm. Find the intersection with the Motor Frame Size to determine the Sheave Selection. For this example with a

182T frame with 920 rpm, from Table 35.2, the Sheave

Arrangement = I.

16. determine the air control:

The Air Control option is selected based on the required damper configuration. The available damper selections are detailed on page 21. For this selection, a 100% fresh air unit without return air was required so the Air Control = DA.

17. determine the evaporative cooler:

An evaporative cooler was not specified so for purposes of this selection the Evaporative Cooler = 0.

18. determine the cooling coil:

A cooling coil cabinet was not specified so for purposes of this selection the Cooling Coil = 0.

Based on the previous steps, the model number for the base unit is the following:

HDG400SMRLN40F2GG1IDA00

Once the basic model has been determined, the additional options and accessories outlined on page 18 to 25 can be added to the unit.

BloWer sHeave assemBly data

adjusting the Blower drive setting

Based on the Sheave Arrangement, Tables 34.1 through 35.5 give the Sheave Assembly numbers used on units that include a blower. The Sheave Arrangement is Digit 19 and is found on the unit Model Identification Plate. The Sheave Assembly describes the motor and blower sheave size and bore as well as the belt provided.

To determine how many turns open the motor sheave should be set for:

1. Follow the Selection Procedure found on pages 28 and 29 to determine what blower rpm is required to meet the job specifications.

2. Locate the unit Model Identification Plate and note Digit 16 and Digit 19 of the model number. Digit 16 is the Blower

Size and Type and Digit 19 is the Sheave Arrangement.

3. Once the Blower Size and Type (Digit 16) is known, enter the proper Sheave Arrangement table.

4. Use the Sheave Arrangement (Digit 19) to determine the

Sheave Assembly provided.

5. Use Table 36.1 and the Sheave Assembly number to determine the required turns open to achieve the desired blower rpm.

6. Set the motor sheave as described in Blower Adjustments.

maintenance

All heating equipment should be serviced before each heating season to assure proper operations. The following items may be required to have more frequent service schedule based on the environment in which the unit is installed, and the frequency of the equipment operation.

Blower assembly

The blower assembly includes the bearings, drive sheaves and belts.

Blower bearings should be checked and lubricated based on the blower manufacturer’s recommendations. Bearings should also be checked for any unusual wear and replaced if needed.

Drive sheaves should be checked at the same time the bearings are inspected. Check to make sure the sheaves are in alignment and are securely fastened to the blower and motor shafts.

Belt tension should be rechecked shortly after the unit has been installed to check for belt stretching. After the initial startup, monthly checks are recommended.

filters

If the unit is supplied with a dirty filter switch and light, clean or replace the filters any time the dirty filter light comes on.

Units which do not have a dirty filter warning light should have the filters checked monthly. Clean or replace if necessary. In dirty atmospheres, filter maintenance may be required more often.

duct furnace

When providing annual maintenance for the duct furnace, keep the unit free from dust, dirt, grease and foreign matter. Pay particular attention to:

1. For HBG/HCG/HDG/HPG units, the combustion air intake and exhaust vent cap louvered openings. For HBP/HCP/

HDP/HPP units, the power exhauster discharge opening and the combustion air inlet louvers.

2. The burner ports and pilot burner orifices (avoid the use of hard, sharp instruments capable of damaging surfaces for cleaning these ports). To check the burner port and pilot burner orifice, see Burner and Pilot Assembly Removal.

3. The air shutters and main burner orifices (avoid the use of hard, sharp instruments capable of damaging surfaces for cleaning these orifices). To check the air shutters and main burner orifices, see for Manifold Assembly Removal.

The heat exchanger should be checked annually for cracks and discoloration of the tubes. If a crack is detected, the heat exchanger should be replaced before the unit is put back into service. If the tubes are dark gray, airflow across the heat exchanger should be checked to insure that a blockage has not occurred or the blower is operating properly.

electrical Wiring

The electrical wiring should be checked annually for loose connections or deteriorated insulation.

Gas Piping & controls

The gas valves and piping should be checked annually for general cleanliness and tightness.

The gas controls should be checked to insure that the unit is operating properly.

manifold assembly removal

1. Shut off gas and electric supply.

2. Remove the side access panel.

3. Disconnect gas manifold at ground union joint.

4. Remove the two screws holding the manifold to the heat exchanger support.

5. Slide the manifold through the manifold bracket.

6. Clean the orifices and adjust the air shutters as necessary.

7. Follow steps 3-6 in reverse to install the manifold assembly.

Burner and Pilot assembly removal to remove the burner

1. Shut off gas and electric supply.

2. Remove the side access panel.

3. Disconnect the pilot supply line from the gas valve.

4. Disconnect the ignition cable from the ignition controller

(located in the electrical junction box). Feed the cable through the bushing in the bottom of the electrical junction box.

5. Remove the screws holding the burner side access panel.

Attached to the panel are the burner retaining pins that align the burner.

6. Slide the burner assembly out. The pilot is attached to the burner assembly.

7. Examine the burner and pilot assembly for cleanliness and/or obstructions as necessary (see Duct Furnace for cleaning instructions).

8. Replace the burner assembly in reverse order. In replacing the burner, be certain that the rear burner slots are located properly on the burner retaining pins. Do not force the burner side access panel, it will not fit if the burner is not properly aligned.

9. Reconnect the ignition cable and pilot gas supply line.

10. Install the side access panel.

11. Turn on the electric and gas supply.

figure 53.1 - Burner and Pilot assembly removal coil maintenance

(for units supplied with a dX or chilled Water coil)

1. Filters should be inspected on a regular basis and changed as needed. Maintaining clean filters is a cost- effective way to help maintain maximum coil performance and service life.

2. Periodic inspection of the coil for signs of corrosion and for leaks is recommended. For DX coils, Small leaks can be detected using a Halide torch. Repair and replacement of the coil and the connecting piping, valves, etc., should be performed as needed by a qualified individual(s).

3. Should the coil surface need cleaning, caution should be exercised in selecting the cleaning solution as well as the cleaning equipment. Improper selection can result in damage to the coil and/or health hazards. Clean the coil from the leaving air-side so that foreign material will be washed out of the coil rather than pushed further in. Be sure to carefully read and follow the cleaning fluid manufacturer's recommendations before using any cleaning fluid.

4. For DX coils, the use of filter-dryers in the system piping is recommended along with a sight glass that has a moisture indicator. Replace the filter dryer(s) as needed.

5. For chilled fluid coils,

A) Maintain the circulated fluid free of sediment, corrosive

products and biological contaminants. Periodic testing

of the fluid followed by any necessary corrective

measures along with maintaining adequate fluid

velocities and proper filtering of the fluid will help to

satisfy this goal.

B) Automatic air vents must be utilized to remove

accumulated air.

C) Freeze Protection - During the winter, chilled water coils

need to be protected against freezing. The two

predominant protective measures are 1) Blowing-out

the coils with air or 2) Flushing coils with inhibited

glycol. It is recommended to use inhibited glycol

designed for HVAC applications for corrosion

protection. Select an inhibited glycol solution that will

protect the coil from the lowest possible temperatures

that can occur at the particular coil's locality.
