All units require certain clearances for proper operation and  
service. Refer to Table 10 for the clearances required for  
combustion, construction, servicing and proper unit opera-  
A filter rack and a high velocity filters are standard.  
tion.  
Filters must always be used and must be kept clean. When  
filters become dirt laden, insufficient air will be delivered by  
the blower, decreasing your units efficiency and increasing  
operating costs and wear-and-tear on the unit and controls.  
Do not permit overhanging structures or shrubs to  
obstruct the condenser air discharge, combustion  
air inlet or vent outlet.  
Filters should be checked monthly especially since this unit is  
used for both heating and cooling.  
CONDENSATE DRAIN  
DUCT WORK  
A condensate trap is recommended to be installed in the con-  
densate drain. The plumbing must conform to local codes.  
Use a sealing compound on male pipe threads. Install the  
condensate drain line (NPTF) to spill into an open drain.  
These units are adaptable to downflow use as well as rear  
supply and return air duct openings. To convert to downflow,  
use the following steps:  
SERVICE ACCESS  
1. Remove the duct covers found in the bottom return and  
supply air duct openings. There are four (4) screws  
securing each duct cover (save these screws to use  
later).  
Access to all serviceable components is provided by the fol-  
lowing removable panels:  
Blower compartment  
Gas control/electrical service access  
2. Install the duct covers, removed in step one, to the rear  
supply and return air duct openings. Secure with the four  
(4) screws used in step one.

approximately 56" above the floor where it will not be subject  
to drafts, sun exposure or heat from electrical fixtures or  
appliances. Follow manufacturer's instructions enclosed with  
the thermostat for general installation procedure. Four color  
coded insulated wires (minimum #18 AWG) should be used  
to connect thermostat to unit. See Figure 3.  
A fused disconnect switch should be field provided for the  
unit. If any of the wire supplied with the unit must be replaced,  
replacement wire must be of the type shown on the wiring  
diagram.  
Electrical line must be sized properly to carry the load. Each  
unit must be wired with a separate branch circuit fed directly  
from the meter panel and properly fused.  
POWER AND CONTROL WIRING  
Field wiring to the unit must conform to provisions of the cur-  
rent N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordi-  
nances. The unit must be electrically grounded in accordance  
with local codes or, in their absence, with the N.E.C./C.E.C.  
Voltage tolerances which must be maintained at the com-  
pressor terminals during starting and running conditions are  
indicated on the unit Rating Plate and Table 8.

FLUE VENT HOOD  
The flue vent hood with screen is not shipped attached. This  
hood must be installed to assure proper unit operation. The  
hood must be fastened to the outside of the side gas control/  
electrical compartment with the screws provided in the bag  
attached to the inside of the gas control/electrical compart-  
ment, see Figure 6.  
If flexible stainless steel tubing is allowed by the  
authority having jurisdiction, wrought iron or steel  
pipe must be installed at the gas valve and extend  
a minimum of two (2) inches outside of the unit  
casing.  
i
Flue hood surfaces may be hot.  
Natural gas may contain some propane. Propane  
being a excellent solvent, will quickly dissolve  
white lead or most standard commercial com-  
pounds. Therefore, a special pipe dope must be  
applied when wrought iron or steel pipe is used.  
Shellac base compounds such as gaskoloc or sta-  
lastic, and compounds such as rectorseal # 5,  
Clyde’s or John Crane may be used.

4. All piping should be cleaned of dirt and scale by ham-  
mering on the outside of the pipe and blowing out the  
loose dirt and scale. Before initial start-up, be sure that  
all of the gas lines external to the unit have been purged  
of air.  
FIGURE 6 - FLUE VENT OUTLET AIR HOOD  
5. The gas supply should be a separate line and installed in  
accordance with all safety codes as prescribed under  
Limitations. After the gas connections have been com-  
pleted, open the main shut-off valve admitting normal  
gas pressure to the mains. Check all joints for leaks with  
soap solution or other material suitable for the purpose.  
NEVER USE A FLAME.  
The flue exhaust hood must be properly installed  
and within the recommended clearances. Further  
communications and action must be given to the  
home or building owner(s) to eliminate any unau-  
thorized human contact around this area during  
the heating cycle. Flue hood surface and immedi-

341426-BIM-A-0108  
begins pressure switch proving before an inter-purge and re-  
ignition attempt.  
SEQUENCE OF OPERATION  
The unit is controlled by a conventional heating/cooling ther-  
mostat common to this class of equipment.  
PILOT FLAME STABILIZATION PERIOD  
The control board de-energizes the spark output, and waits  
for a 2 second flame stabilization period before energizing the  
main gas valve.  
HEATING  
The control board begins a call for heat when W1 is ener-  
gized (connected to R). The control ignores W2 until pilot  
ignition has been established.  
If flame is lost during the flame stabilization period, the con-  
trol board counts it as a flame loss and retries ignition or locks  
out flashing a "5" on the LED.  
The control checks to see if the pressure switch is open. If the  
pressure switch is closed, the control board flashes "3" on the  
LED and waits indefinitely for it to open. When the pressure  
switch is sensed as open, the control begins pressure switch  
proving period. If the call for heat is lost, the control goes  
back to Standby.  
HEAT BLOWER ON DELAY  
The control board waits for 30 seconds and then energizes  
the indoor blower heat speed. Blower on delay time begins at  
the start of flame proving period in the trial for ignition.  
PRESSURE SWITCH PROVING  
If the thermostat demand for heat is removed, the control de-  
energizes the gas valve, energizes the blower on heat speed  
and initiates a post-purge and heat blower off delay.  
The control board energizes the induced draft motor (High  
speed for 2 stage model) and waits for the low pressure  
switch to close. When the low pressure switch closes, the  
control begins Pre-purge period. If the call for heat is lost, the  
control de-energizes the inducer without post-purge and  
returns to standby.  
MAIN BURNER OPERATION  
High heat warm-up  
Two stage models run high heat for the first 60 seconds fol-  
lowing Pilot Flame Stabilization period regardless of W2  
demand. If W2 is not energized at the end of this 60 second  
period the control de energizes the high gas output and steps  
the inducer to low speed. If W2 is energized the control  
remains on high heat.  
If the low pressure switch does not close within 10 seconds of  
inducer energizing, the control board flashes "2" on the LED.  
If the pressure switch does not close within 5 minutes of  
inducer energizing, the control shuts off the inducer for 30  
seconds, then energizes the inducer for another 5 minute try  
to close the pressure switch. This cycle continues indefinitely  
until either the pressure switch is proved closed, or the call  
for heat ends.  
There is no high heat warm-up on single stage models  
Low heat  
PRE-PURGE  
The control board keeps the pilot gas valve, main gas valve  
and induced draft motor energized while continuously moni-  
toring the call for heat, low pressure switch, and flame status.  
The control board monitors the low pressure switch and  
ensures it remains closed during pre-purge. If the pressure  
switch opens, the control goes back to pressure switch prov-  
ing mode. The control waits for a 15 second pre-purge  
period, then begins the ignition trial  
If the call for heat (W1) is lost, the control de-energizes the  
gas valve and begins post purge.  
If low pressure switch opens, the control de-energizes the  
gas valve and begins pressure switch proving mode.  
IGNITION TRIAL PERIOD  
The control board energizes the pilot gas valve and spark  
outputs for an 85 second Ignition trial. The control de-ener-  
gizes the spark when flame is sensed and enters a flame sta-  
bilization period.  
If flame is lost, the control de-energizes the gas valve within  
2.0 second and counts the flame loss. If flame has been lost  
more than 16 times within the same call for heat, the control  
board locks out flashing "5" on the LED. If flame has been  
lost less than 16 times, the control attempts re-ignition after a  
300 second inter-purge period.  
If flame is not established within the ignition trial period, the  
control de-energizes the spark and gas valve and begins an  
inter-purge period before attempting another ignition trial.  
High heat  
If the call for heat is lost during an ignition trial period, the  
control immediately de-energizes spark and gas. The control  
runs the inducer motor through a post purge period before  
de-energizing.  
If the W2 terminal was energized more than 1 second before  
W1 at the start of the call for heat, and remains continuously  
energized through the call for heat, the control considers it to  
be connected to a single stage thermostat and implements a  
10 minute Auto staging feature. The 2nd stage thermostat  
call is ignored until 10 minutes into steady heat (9 minutes  
after high heat warm-up ended).  
If the pressure switch is lost during an ignition trial period, the  
control immediately de-energizes spark and gas. The control

341426-BIM-A-0108  
The control recognizes a call for 2nd stage heat when W2 is  
energized (connected to "R"). The control energizes the high  
gas output and induced draft motor on high speed.  
Rollout switch lockout shall not reset automatically.  
POWER INTERRUPTIONS  
Power interruptions of any duration shall not cause lockout or  
any operation requiring manual intervention.  
If the call for 2nd stage heat goes away and the 1st stage call  
remains, the control de energizes the high gas valve, drops  
inducer speed to low, and returns to low heat operation.  
FLAME PRESENT WITH GAS OFF  
Response to loss of W1, low pressure switch, and flame are  
identical to low heat operation.  
If flame is sensed for longer than 4.0 seconds during a period  
when the gas valve should be closed, the control will enter  
lockout flashing "8" on the LED. The control will turn on the  
inducer blower while the flame is present.  
POST PURGE  
The control board runs the induced draft motor for a 30 sec-  
ond post-purge period, and then de-energizes the inducer. If  
a call for heat occurs during post-purge, the control finishes  
the post-purge, drops inducer out to re-prove open pressure  
switch before continuing with the heat cycle.  
GAS VALVE STUCK OPEN OR CLOSED  
If either or both Pilot and Main Gas valve outputs are sensed  
to be off for more than 1 second when commanded to be on,  
the control board shuts off all outputs and enters a hard  
lockout flashing "9" on the LED.  
HEAT BLOWER OFF DELAY  
If the Pilot valve or Main valve output is sensed to be  
energized for more than 1 second when commanded to be  
off, the control de-energizes the induced draft motor (if flame  
is not present) to attempt to open the pressure switch to de-  
energize the gas valve. If the pilot or main gas valve is still  
sensed as energized after the inducer has been off for 5  
seconds, the control re-energizes the inducer to attempt to  
vent the unburned gas. In either case, the control enters a  
hard lockout flashing "9" on the LED. If the pilot or main valve  
becomes Un-Welded the inducer will de-energize, but the  
control will remain in a hard lockout and not respond to any  
thermostat demands.  
The control board de-energizes the indoor blower motor after  
a delay time as selected by movable shunt (60, 90, 120 or  
180 seconds). Blower timing begins when the thermostat is  
satisfied or heat cycle was interrupted. The control returns to  
standby when the blower off delay is complete.  
If the thermostat call for heat returns before the blower off  
delay is complete, the control begins an ignition sequence  
with pre-purge while the blower off delay continues.  
LOCKOUT  
While in lockout, the control board keeps the pilot gas valve,  
main gas valve and induced draft motor de-energized.  
The only way to recover from a hard lockout is to remove and  
then reapply 24VAC power to the control board.  
Lockouts due to failed ignition or flame losses may be reset  
by removing the call for heat (W1) for more than 1 second,  
but less than 20 seconds, or by removing power from the  
control for over 0.25 seconds. The control will automatically  
reset lockout after 60 minutes.  
FLAME SENSE CIRCUIT FAILURE  
If the control detects an internal hardware failure in the flame  
sense circuit, it shuts off all outputs and enters a hard lockout  
flashing "10" on the LED. The control will not respond to  
thermostat demands during a hard lockout.  
Lockouts due to detected internal control faults will reset after  
60 minutes or power interruption.  
The only way to recover from a hard lockout is to remove and  
then reapply 24VAC power to the control. If problem persist  
after removal and reapplication of 24VAC power, the board  
may need to be replaced.  
HIGH TEMPERATURE LIMIT SWITCH  
Any time the high temperature limit switch is open the control  
board will run the indoor blower motor on heat speed, the  
inducer (on high speed for 2 stage models), de-energize the  
gas valve, and flash "6" on the LED. When the high tempera-  
ture switch closes, the control will restart the ignition  
sequence beginning with pre-purge.  
SAFETY CONTROLS  
The control circuit includes the following safety controls:  
1. Limit Switch (LS) - This control is located inside the  
heat exchanger compartment and is set to open at the  
temperature indicated in the Temperature Controls Table  
of the unit wiring diagram. It resets automatically. The  
limit switch operates when a high temperature condition  
caused by inadequate supply air flow occurs, thus shut-  
ting down the ignition control and closing the main gas  
valve and energizing the blower.  
ROLLOUT SWITCH  
If the rollout switch opens for more than 0.25 seconds, the  
control board will run the inducer (on high speed for 2 stage  
models) for a post-purge period, immediately de-energize the  
gas valve, and flash "7" on the LED. The blower output will be  
energized during an open rollout condition.  
If the rollout switch closes, the control shall remain locked out  
until power removed or "W" is removed.

341426-BIM-A-0108  
2. Pressure Switch (PS) - If the draft motor should fail, the  
pressure switch prevents the ignition controls and gas  
valves from being energized.  
CIRCULATING FAN  
When the thermostat calls for FAN, the thermostat terminal G  
is energized signaling the circulating fan to run at the cool  
speed.  
3. Flame Sensor - The flame sensor and controls are  
located per Proper Flame Adjustment, Figure 12. If an  
ignition control fails to detect a signal from the flame sen-  
sor indicating the pilot flame is properly ignited, then the  
main gas valve will not open.  
If a call for COOL occurs, the circulating fan continues to run  
at the cool speed.  
If a call for HEAT occurs, the circulating fan switches to heat  
speed after a 30 second delay.  
4. Rollout Switch (RS) - This switch is located in the  
burner vestibule. In the event of a sustained main burner  
flame rollout, it shuts off the ignition control and closes  
the main gas valve.  
When the thermostat ends the call for FAN, the thermostat  
terminal G is de-energized, de-energizing the circulating fan.  
NOTE: The manual reset Rollout Switch (RS) must be reset  
before allowing furnace operation.  
START-UP  
5. Auxiliary Limit Switch (ALS) - This control is located  
inside the heat exchanger compartment and is set to  
open at 160°F. It is a manual reset switch. If ALS trips,  
then the primary limit (LS) has not functioned correctly.  
Replace the primary limit LS.  
PRE-START CHECK LIST

After the temperature rise has been determined, the CFM can  
be calculated as follows:  
After about 20 minutes of operation, determine the furnace  
temperature rise. Take readings of both the return air and the  
heated air in the ducts about six feet from the furnace where  
they will not be affected by radiant heat. Increase the blower  
CFM to decrease the temperature rise; decrease the blower  
CFM to increase the rise.

All units have direct drive multi-speed blower motors. Refer to  
the unit wiring diagram and connect the blower motor for the  
desired motor speed.  
FIGURE 12 - PROPER FLAME ADJUSTMENT  
To adjust the pilot flame:  
CHECKING GAS INPUT  
NATURAL GAS  
1. Remove the pilot adjustment cover screw.  
2. Adjust the pilot adjustment screw to achieve the proper  
pilot flame.  
1. Turn off all other gas appliances connected to the gas  
meter.  
3. Replace the pilot adjustment cover screw after the pilot  
flame is set.  
2. With the furnace turned on, measure the time needed for  
one revolution of the hand on the smallest dial on the  
meter. A typical gas meter usually has a 1/2 or a 1 cubic  
foot test dial.  
To remove the pilot assembly:  
1. Disconnect the wiring from the control board to the pilot  
assembly.  
3. Using the number of seconds for each revolution and the  
size of the test dial increment, find the cubic feet of gas  
consumed per hour from Table 12.  
2. Remove the two (2) #8 screws holding the pilot assem-  
bly in place.  
3. Remove the pilot assembly.  
If the actual input is not within 5% of the furnace rating with  
allowance being made for the permissible range of the regu-  
lator setting, replace the orifice spuds with spuds of the  
proper size.  
ADJUSTMENT OF TEMPERATURE RISE  
NOTE: To find the BTU input, multiply the number of cubic  
feet of gas consumed per hour by the BTU content  
of the gas in your particular locality. (Contact your  
gas company for this information since it varies  
widely from city to city.)

1. Remove the two ¼ inch dot plugs in the duct panel.  
2. Insert at least 8 inches of ¼ inch tubing into each of  
these holes for sufficient penetration into the airflow on  
both sides of the indoor coil.  
3. Using an inclined manometer, determine the pressure  
drop across the dry evaporator coil. Since the moisture  
on an evaporator coil may vary greatly, measuring the  
pressure drop across a wet coil under field conditions  
would be inaccurate. To ensure a dry coil, the compres-  
sors should be deactivated while the test is being run.  
4. Knowing the pressure drop across a dry coil, the actual  
CFM through the unit can be determined from the curve  
in Coil Delta P vs. Supply Air CFM figure.

Failure to properly adjust the total system air quan-

After readings have been obtained, remove the tubes and  
reinstall the two ¼ inch plugs removed in Step 1.

De-energize the compressors before taking any test mea-  
surements to ensure a dry indoor coil.

1.  
EXAMPLE: By actual measurement, it takes 38 seconds for the  
hand on the 1-cubic foot dial to make a revolution with just a  
100,000 BTUH furnace running. Using this information, locate  
38 seconds in the first column of Table 12. Read across to the  
column headed “1 Cubic Foot,” where you will see that 95 cubic  
feet of gas per hour are consumed by the furnace at that rate.  
Multiply 95 x 1050 (the BTU rating of the gas obtained from the  
local gas company). The result is 99,750 BTUH, which is close  
to the 100,000 BTUH rating of the furnace.

TYPICAL WIRING DIAGRAM NOTES  
(SEE FIGURES 14 AND 15)  
1. All field wiring to be accomplished following city, local  
and/or national codes in effect at time of installation of  
this unit.  
7. Shunt contact also used with crankcase heater.  
(optional)  
2. Caution: Label all wires prior to disconnection when ser-  
vicing controls. Wiring errors can cause improper and  
dangerous operation. If any of the wire as supplied with  
this unit must be removed it must be replaced with type  
105°C, 600V wire or equivalent clearly renumbered for  
identification. Verify proper operation after servicing.  
8. Unit factory wired for low or medium speed indoor blower  
operation. To change motor speed, connect speed tap  
wires from indoor blower motor, per Detail A (Figure 16).  
Tape unused speed tap wires to prevent shorting and  
secure.  
9. Select indoor blower speed to remain within the temper-  
ature rise range on the nameplate in heating.  
3. Motors inherently protected.  
4. Factory wired for 460V operation.  
5. See unit nameplate for maximum fuse size and/or circuit  
breaker size and minimum circuit ampacity.  
6. If both LR and ASCT are present, wire 801/BL and 805/  
BL are connected to ASCT-3. If only LR is present wire  
Open all disconnects before servicing this unit.
