STD = Standard equipment.
1 CCM Compressor control module has adjustable 30 second to 5 minute delay-on-break
timer. On initial power up, or any time the power is interrupted, the delay-on-make
will be 2 minutes plus 10% of the delay-on-break setting. There is no delay-onmake during routine operation of the unit. The module also provides the lockout
feature (with 1 retry) for high and/or low pressure controls, and a 2 minute timed
bypass for low pressure control.
2 HPC High pressure control is auto reset. Always used with compressor control module
(CCM) which is included. See note 1.
3 LPC Low pressure control is auto reset. Always used with compressor control module
(CCM) which is included. See note 1.
4 LAC Low ambient control permits cooling operation down to 0°F.
CAUTION
During the initial firing of the burners there will probably be some amount of smoke issued to the
circulating air stream as the result of residual oil burning off of the heat exchanger tubes. This oil
is required during the forming process of the stainless steel heat exchanger tubes to facilitate the
bending. OSHA or the National Toxicology Program does not list the oil as a carcinogen. In
vapor form this may be irritating to the eyes or could cause headaches. This is a one-time
occurrence, and ventilation of the space may be required depending upon the space being
conditioned.
1. IMPORTANT
3. DUCT WORK
The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians. All duct work or portions thereof not in
the conditioned space should be properly insulated in
order to both conserve energy and prevent condensation
or moisture damage.
The unit is designed for use with or without duct work.
See Warning on Page 7. Flanges are provided for
attaching the supply and return ducts. These
instructions explain the recommended method to install
the air cooled self-contained electric air conditioning
and gas heating unit and the electrical wiring
connections and gas piping to the unit. The refrigerant
system is completely assembled and charged. All
internal wiring is complete.
2. APPLICATION
This is a fan-assisted forced air gas furnace with
electric air conditioning for outdoor installation. A fanassisted furnace is equipped with an integral
mechanical means to draw products of combustion
through the combustion chamber and heat exchanger.
The furnace installation must conform with local
building codes and ordinances or, in their absence, with
the National Fuel Gas Code ANSI Z223.1 or CAN/
CGA-B149.1, latest edition, and the National Electrical
Code ANSI/NFPA-7 or CSA C22.1, latest edition. It is
the personal responsibility and obligation of the
purchaser to contact a qualified installer to assure that
installation is adequate and is in conformance with
governing codes and ordinances.
These instructions and any instructions packaged with
any separate equipment required to make up the entire
heating/cooling system should be carefully read before
beginning the installation. Note particularly “Starting
Procedure” and any tags and/or labels attached to the
equipment.
All duct work, supply and return, must be properly sized
for the design air flow requirement of the equipment.
Air Conditioning Contractors of America (ACCA) is an
excellent guide to proper sizing.
Refer to Tables 10, 11, 12, 13, 14 and 15 in this Manual
for maximum static pressure available for duct design.

In all cases, there must be a metal duct
connection made to the supply air flange, and
a one inch clearance to combustibles must be
maintained to this duct connection.
For free blow applications, a metal sleeve
must be used in the wall opening itself, again
maintaining a one inch clearance to
combustibles.
Failure to use the sheet metal can cause
fire resulting in property damage, injury, or
death.
4. HIGH ALTITUDE APPLICATIONS
Ratings of gas utilization equipment are based on sea
level operation and need not be changed for operation
at elevations up to 6,000 feet. For operation at
elevations above 6,000 feet and in the absence of
specific recommendations from the local authority
having jurisdiction, equipment ratings shall be reduced
as specified in Section 21.
5. TRANSPORTATION DAMAGE
All units are packed securely in shipping container.
All units should be carefully inspected upon arrival for
damage. In the event of damage, the consignee should:
1. Note on delivery receipt of any damage to container.
See Figure 3 and clearance information in Section 9
and Table 2 for additional information.
Design the duct work according to methods given by
the Air Conditioning Contractors of America (ACCA).
When duct runs through unheated spaces, it should be
insulated with a minimum of one inch of insulation.
Use insulation with a vapor barrier on the outside of
the insulation. Flexible joints should be used to
connect the duct work to the equipment in order to
keep the noise transmission to a minimum.
A one inch clearance to combustible material for the
first three feet of duct attached to the outlet air frame is
required. See Wall Mounting Instructions and Figures
2, 2A and 3 for further details.
Ducts through the walls must be insulated and all joints
taped or sealed to prevent air or moisture entering the
wall cavity.
Some installations may not require any return air duct.
A metallic return air grille is required with installations
not requiring a return air duct. The spacing between
louvers on the grille shall not be larger than 5/8 inch.
Any grille that meets with the 5/8 inch louver criteria
may be used. It is recommended that Bard Return Air
Grille or Return Filter Grille be installed when no
return duct is used. Contact distributor or factory for
ordering information. If using a return air filter grille,
filters must be of sufficient size to allow a maximum
velocity of 400 fpm.
NOTE: If no return air duct is used, applicable
installation codes may limit this cabinet to
installation only in a single story structure.
2. Notify carrier promptly, and request an inspection.
3. In case of concealed damage, the carrier must be
notified as soon as possible within 15 days after
delivery.
4. Claims for any damage, apparent or concealed,
should be filed with the carrier, using the following
supporting documents:
A. Original Bill of Lading, certified copy, or
indemnity bond.

12. VENT RESIZING INSTRUCTIONS
13. FRESH AIR INTAKE
When an existing furnace is removed from a venting
system servicing other appliances, the venting system is
likely to be too large to properly vent the remaining
attached appliances.
All units are built with fresh air inlet slots punched in
the service panel.
The following steps shall be followed with each of the
appliances remaining connected to the common venting
system, placed in operation one at a time while the
other appliances remaining connected to the common
venting system are not in operation.
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and
horizontal pitch, as required in the National Fuel Gas
code, ANSI Z223.1 or the CAN/CGA B149
Installation Codes and these instructions. Determine
that there is no blockage or restriction, leakage,
corrosion and other deficiencies which could cause
an unsafe condition.
3. In so far as is practical, close all building doors and
windows and all doors between the space in which
the appliance(s) connected to the venting system are
located and other spaces of the building. Turn on
clothes dryers and any appliances not connected to
the venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they will
operate at maximum speed. Do not operate a
summer exhaust fan. Close fireplace dampers.
4. Follow the lighting instructions. Place the appliance
being inspected in operation. Adjust thermostat so
appliance shall operate continuously.
5. Test for draft hood equipped appliance spillage at the
draft hood relief opening after 5 minutes of main
burner operation. Use the flame of a match or
candle.
6. After it has been determined that each appliance
connected to the venting system properly vents when
tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other gasburning appliances to their previous conditions of
use.
If the unit is equipped with a fresh air damper
assembly, the assembly is shipped already attached to
the unit. The damper blade is locked in the closed
position. To allow the damper to operate, the
maximum and minimum blade position stops must be
installed. See Figure 9.
All capacity, efficiency and cost of operation
information as required for Department of Energy
“Energyguide” Fact Sheets is based upon the fresh air
blank-off plate in place and is recommended for
maximum energy efficiency.
The blank-off plate is available upon request from the
factory and is installed in place of the fresh air damper
shipped with each unit.
One of several other ventilation options may be
installed. Refer to model number and/or supplemental
installation instructions.
14. CONDENSATE DRAIN
A plastic drain hose extends from the drain pan at the
top of the unit down to the unit base. There are
openings in the unit base for the drain hose to pass
through. In the event the drain hose is connected to a
drain system of some type, it must be an open or vented
type system to assure proper drainage.

PROPER PIPING PRACTICE
CHECKING THE GAS PIPING
Before turning gas under pressure into piping, all
openings from which gas can escape should be closed.
Immediately after turning on gas, the system should be
checked for leaks. This can be done by watching the 1/2
cubic foot test dial and allowing 4 minutes to show any
movement, and by soaping each pipe connection and
watching for bubbles. If a leak is found, make the
necessary repairs immediately and repeat the above test.
The furnace must be isolated from the gas supply piping
system by closing the manual shut off valve on the
combination gas control valve during pressure testing of
the gas supply piping system at pressures up to 1/2
PSIG. The furnace and its individual shut off valve must
be disconnected from supply piping and supply piping
capped during any pressure testing of supply piping
system at test pressures in excess of 1/2 PSIG.
Defective pipes or fittings should be replaced and not
repaired. Never use a flame or fire in any form to locate
gas leaks; use a soap solution.
After the piping and meter have been checked
completely, purge the system of air. DO NOT bleed air
inside the furnace. Be sure to check and relight all the
gas pilots on other appliances that may have been
extinguished because of interrupted gas supply.

use with Propane (LP) gas. Propane gas
conversion kit number WGCK-1 is designed
for conversions of units installed from
0 – 6,000 feet elevations. Propane gas
conversion kit number WGCK-2 is designed
for conversions of units installed from 6,001
– 10,000 feet elevations. These kits may
be purchased from your local distributor.
WARNING
When converting from propane (LP) gas to
natural gas, the gas orifice spuds and gas
valve spring must be replaced and the gas
valve regulator pressure must be adjusted
correctly. Failure to do so can result in fire,
injury or death. Refer to Tables 8 and 8A for
proper orifice sizing.
Natural gas spring kit, Part number 5603-007,
can be purchased through your local
distributor.
19. MANIFOLD PRESSURE
ADJUSTMENT
You will need a 0 to 15 inch water manometer with 0.1
inch resolution and a 1/8" NPT manual shut off valve to
measure actual manifold pressure.
WARNING
Correct manifold pressure is necessary for
proper ignition and burner operation. Failure
to accurately adjust pressure could cause
heat exchanger failure.
1. Turn off gas at equipment shut off valve in gas
supply line just ahead of furnace.
2. Remove plug from outlet pressure tap in gas control
or gas manifold.
3. Install 1/8" NPT manual shut off valve in hole
vacated by plug. Make sure shut off valve is in off
position.
4. Attach manometer to 1/8" NPT manual shut off
valve just installed.
Manual 2100-365K
Page
22
5. Slowly open equipment shut off valve in gas supply
line just ahead of furnace. Start furnace following
"Operating Instructions" on front door.
6. Slowly open 1/8" NPT manual shut off valve leading
to manometer.
7. Read manifold pressure on manometer.
8. Adjust manifold pressure by turning gas control
regulator adjusting screw clockwise to increase
pressure or turning counterclockwise to decrease
pressure. Manifold pressure must be within
allowable range as follows:
• Natural gas manifold pressure must be between
3.2 and 3.8 inches W.C. Rated pressure is 3.5
inches.
• Propane gas (LP) manifold pressure must be
between 9.7 and 10.3 inches W.C. Rated
pressure is 10 inches.
NOTE: For natural gas, if gas flow rate can't be
properly set within these pressure ranges
then you must change main burner orifices to
obtain proper gas flow rate.
9. Shut off furnace. Turn off gas at equipment shut off
valve in gas supply line just ahead of furnace. Install
outlet pressure tap plug in gas control. Turn on gas.
10. Check regulator adjustment cover screw and gas
control plug for gas leaks. Use a commercial soap
solution made for leak detection.
20. CHECKING GAS INPUT RATE
It is the installer's responsibility to see that the BTU
input rate of the furnace is properly adjusted. Underfiring could cause inadequate heat, excessive
condensation or ignition problems. Overfiring could
cause sooting, flame impingement or overheating of
heat exchanger.
WARNING
Failure to adjust furnace to the proper firing
rate could cause heat exchanger failure.
Depending on your local gas heating value and
elevation, you may need to adjust manifold pressure or
change orifices to get proper gas input rate. Check
with your local gas supplier to determine heating value
(BTU/cu. ft.) of natural gas in your area.
NOTE: If furnace is being installed at an altitude of
more than 6,000 feet above sea level, you
must derate the furnace. See Section 21
"Standard Orifice Sizing and High Altitude
Derate".
NATURAL GAS INPUT RATE
Natural gas heating value (BTU/cu. ft.) can vary
significantly. Before starting natural gas input check,
obtain gas heating value at your location from local
supplier. You will need a stopwatch to measure actual
gas input.
9. If you left water heater, dryer or range pilots on,
allow for them in calculating correct furnace gas
input. A quick way is to allow 1,000 BTU per hour
for a water heater, 500 BTU per hour for dryer and
500 BTU per hour for each range burner pilot.
Example:
1. Gas supply pressure must be between 5 and 7 inches
W.C. for natural gas.
If you left gas water heater, dryer, two range burner
pilots and one oven pilot on, allow:
2. Turn off all other gas appliances. You may leave
pilots on.
Water heater pilot
Dryer pilot
2 range burner pilots
1 range oven pilot
3. Start furnace following “Operating Instructions” on
front door.
4. Let furnace warm up for 6 minutes.
5. Locate gas meter. Determine which dial has the
least cubic feet of gas and how many cubic feet per
revolution it represents. This is usually one-half, one
or two cubic feet per revolution.
6. With stopwatch, measure time it takes to consume
two cubic feet of gas.
•
If dial is one-half cubic foot per revolution,
measure time for four revolutions.
•
If dial is one cubic foot per revolution, measure
time for two revolutions.
•
If dial is two cubic feet per revolution, measure
time for one revolution.
7. Divide this time by two. This gives average time for
one cubic foot of gas to flow through meter.
Example: If it took 58 seconds for two cubic feet to
flow, it would take 29 seconds for one cubic foot to
flow.
8. Calculate gas input using this formula:
Gas Heating Value (BTU/cu. ft.)
x 3,600 sec/hr
Gas input =
= BTU/hour
Time (Seconds for one
cubic foot of gas)
Example:
Assume it took 29 seconds for one cubic foot of gas
to flow and heating value of 1,000 BTU/cu. ft.
Gas input =
1,000 x 3,600
29
= 124,138 BTU
If you left no other pilots on, this is the furnace gas
input.
1,000 BTU per hour
500 BTU per hour
1,000 BTU per hour
500 BTU per hour
3,000 BTU per hour
Subtracting 3,000 BTU per hour from 124,138 BTU
per hour measured above equals 121,138 BTU per
hour. This would be the correct furnace gas input
after allowing for pilots left on.
10. Manifold pressure may be adjusted within the range
of 3.2 inches W.C. to 3.8 inches W.C. to get rated
input ± 2 percent. See Section 17, “Manifold
Pressure Adjustment”. If you cannot get rated input
with manifold pressure within the allowable range,
you must change orifices.
PROPANE (LP) GAS INPUT RATE
WARNING
Propane (LP) gas installations do not have
gas meters to double check input rate.
Measure manifold pressure adjustment with
an accurate manometer. Failure to accurately
adjust pressure could cause heat exchanger
failure, asphyxiation, fire or explosion,
resulting in damage, injury or death.
1. Make sure you have proper main burner orifices.
2. Gas supply pressure must be between 11 and 13
inches W.C. for propane (LP) gas.
3. Start furnace following “Operating Instructions” on
front door.
4. Let furnace warm up for 6 minutes.
5. Adjust manifold pressure to 10.0 W.C. ± 0.3 inches
W.C. See Section 19, “Manifold Pressure
Adjustment”.
WARNING
Do not set Propane (LP) manifold pressure at
11.0 inches W.C. It could cause heat
exchanger failure.

21. STANDARD ORIFICE SIZING AND
HIGH ALTITUDE DERATE
This furnace is shipped with fixed gas orifices for use
with Natural Gas and sized for 1000 BTU/cubic foot
gas. Make sure actual gas input does not exceed rating
plate input. You may need to change orifices to get
correct gas input. Whether you do or not depends on
input, and your gas heat value at standard conditions
and elevation. Consult your local gas supplier for gas
heat value and any special derating requirements. See
Section 20 for more information.
At higher altitudes, the density of the air is reduced.
Therefore, for proper combustion, the quantity of gas
burned in the furnace must also be reduced. This is
called derating. This unit must be derated when
installed at altitudes greater than 6,000 feet above sea
level. A high altitude pressure switch must also be
installed for operation above 6,000 feet. High altitude
pressure switch kit number 8620-189 is designed for
this application.
It is the installer’s responsibility to see that the furnace
input rate is adjusted properly. Derating must be
achieved by reducing the size of the main burner
orifices. Derating the furnace by adjusting the manifold
pressure lower than the range specified in the Section
19, “Manifold Pressure Adjustment” is considered to be
an improper procedure.
Above 6,000 feet elevation orifice changes are required,
and capacity reductions are a function of altitude
impact and orifice change. Pressure switch change is
required above 6,000 feet elevation. For Natural Gas
see the Altitude Table 7 below and the Orifice Tables 8
and 8A on following pages.

22. CONVERSION OF GAS INPUT BTUH
FROM HIGH TO LOW RATING
All the derated WG series units are produced with
maximum BTUH input orifices installed. To field
convert input, a change to main burner orifices is
required.
NOTE: No change to air orifices is necessary. A set
of low input orifices is shipped with every
unit. They will be found packaged in a bag
behind the burner door. Refer to the unit
rating plate to confirm the proper orifice size.
Proper installation of the orifices is detailed
as follows:
A. Shut off electrical supply to the unit.
B. Shut off gas supply to the unit.
C. Remove burner access panel.
D. Disconnect gas valve from gas supply piping.
E. Disconnect the two wires from the gas valve.
F. Remove the manifold assembly so that orifices are
now accessible and remove orifices.
G. Apply a modest amount of pipe compound to the
new orifices and screw them into the manifold.
H. To assemble burner reverse steps A through G.
WARNING
Failure to follow these instructions could
create a hazard resulting in property damage,
bodily injury, or death.
23. MEASURING AIR TEMPERATURE
RISE
Air temperature rise (supply air temperature minus
return air temperature) must be within allowable air
temperature rise range specified on furnace rating plate
and in Table 1.
You will need 2 thermometers with 1 degree resolution
capable of reading up to 200 degrees F. Check
thermometers to make sure they agree, or compensate
accordingly.
Follow this procedure:
2. Set balancing dampers in supply duct system.
3. Check duct work for obstructions or leaks.
4. Make sure filters are clean and in place.
5. Place one thermometer in supply air plenum
approximately 2 feet from furnace. Locate
thermometer tip in center of plenum to ensure proper
temperature measurement.
6. Place second thermometer in return air duct
approximately 2 feet from furnace. Locate
thermometer tip in center of duct to ensure proper
temperature measurement.
7. Set room thermostat on highest temperature setting.
Operate furnace 10 minutes. Record supply air and
return air temperatures.
8. Calculate air temperature rise by subtracting return
air temperature from supply air temperature.
• If air temperature rise is above the temperature
rise range on rating plate, furnace is overfired
or has insufficient airflow. Check gas input
following the instructions in Section, “Checking
Gas Input Rate”. If air temperature rise is still
above temperature rise range specified, more
heating air flow is needed. Check duct work and
grilles to make sure all are properly sized.
• If air temperature rise is below the temperature
rise range on rating plate, furnace is underfired
or has too much airflow. Check gas input
following the instructions in Section, “Checking
Gas Input Rate”. If air temperature rise is still
below temperature rise range specified, less
heating air flow is needed. Adjust dampers or
grilles as needed.
• After making adjustments, you must check air
temperature rise to verify that resulting air
temperature rise is within allowable range. If
air temperature rise is still outside the
temperature rise range specified on rating
plate, check duct system design with a
qualified heating engineer. It may be
necessary to re-size the duct work. Recheck
air temperature rise after revising duct systems.
9. Set room thermostat to desired setting.
10. Remove thermometers and seal duct work holes.
NOTE: Failure to seal holes could result in reduced
system performance.
1. Open supply air registers and return air grilles.
Make sure the registers and grilles are free of
obstruction from rugs, carpets, drapes or furniture.

25. COMPRESSOR CONTROL MODULE
The compressor control is an anti-short cycle/lockout
timer with high and low pressure switch monitoring and
alarm output.
ADJUSTABLE DELAY-ON-MAKE AND BREAK
TIMER
On a call for compressor operation the delay-on-make
period begins which will be 10% of the delay-on-break
setting. When the delay-on-make is complete and the
high pressure switch (and low pressure switch if
employed) is closed, the compressor contactor is
energized. Upon shutdown the delay-on-break timer
starts and prevents restart until the delay-on-break and
delay-on-make periods have expired.
Manual 2100-365K
Page
28
HIGH PRESSURE SWITCH AND LOCKOUT
SEQUENCE (Standard Feature)
If the high pressure switch opens, the compressor
contactor will de-energize immediately. The lockout
timer will go into a soft lockout and stay in soft lockout
until the high pressure switch closes and the delay-onmake time has expired. If the high pressure switch
opens again in this same operating cycle the unit will
go into manual lockout condition and the alarm circuit
will energize. Recycling the wall thermostat resets the
manual lockout.
LOW PRESSURE SWITCH, BYPASS, AND
LOCKOUT SEQUENCE
NOTE: The low pressure switch is an optional
control and the bypass and lockout sequence
are part of the standard compressor control
module.
If the low pressure switch opens for more that 120
seconds, the compressor contactor will de-energize and
go into a soft lockout. Regardless the state of the low
pressure switch, the contactor will reenergize after the
delay-on-make time delay has expired. If the low
pressure switch remains open or opens again for longer
than 120 seconds the unit will go into manual lockout
condition and the alarm circuit will energize.
Recycling the wall thermostat resets the manual
lockout.
ALARM OUTPUT
PHASE MONITOR
Alarm terminal is output connection for applications
where alarm signal is desired. This terminal is powered
whenever compressor is locked out due to HPC or LPC
sequences as described.
All units with three phase scroll compressors are
equipped with a three phase line monitor to prevent
compressor damage due to phase reversal.
NOTE: Both high and low pressure switch controls
are inherently automatic reset devices. The
high pressure switch and low pressure switch
cut out and cut in settings are fixed by
specific air conditioner or heat pump unit
model. The lockout features, both soft and
manual, are a function of the Compressor
Control Module.
If phases are reversed, the red fault LED will be lit and
compressor operation is inhibited.
The phase monitor in this unit is equipped with two
LEDs. If the “Y” signal is present at the phase monitor
and phases are correct, the green LED will light.
If a fault condition occurs, reverse two of the supply
leads to the unit. Do not reverse any of the unit factory
wires as damage may occur.
ADJUSTMENTS
ADJUSTABLE DELAY-ON-MAKE AND
DELAY-ON-BREAK TIMER
The potentiometer is used to select Delay-on-Break

TOP VIEW OF GAS CONTROL
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation. Verify
proper operation after servicing.
WARNING
Follow these procedures before inspecting
furnace.
• Turn room thermostat to its lowest or off
setting.
• Turn off manual gas shut off valve.
• Wait at least 5 minutes for furnace to cool
if it was recently operating.
• Turn off furnace electrical power; failure
to do so could result in injury or death.
MAIN BURNER
Observe the main burners in operation. The flame
should be mostly “blue” with possibly a little orange
(not yellow) at the tips of the flame. The flames should
be in the center of the heat exchanger tubes and not
impinging on the heat exchanger surfaces themselves.
Observe the fire until the blower starts (there is a
normal delay period until the heat exchanger warms
up). There should be no change in the size or shape of
the flame. If there is any wavering or blowing of the
flame on blower start-up, it is an indication of a
possible leak in the heat exchanger.
MIS-165
BURNERS / HEAT EXCHANGER / FLUE GAS
PASSAGE WAYS
The burners, heat exchanger and interior flue gas
passages may be inspected using a light on small mirror
or an extension handle. Remove the screws securing
the inducer and collector box. Now inspect the upper
tubes of the heat exchanger.
Check the exterior of the heat exchanger and the
interior flue gas passages for any evidence of
deterioration due to corrosion, cracking or other causes.
If signs of sooting exist, remove the burners and clean
the heat exchanger, as required.
28. MAINTAINING UNIT IN GOOD
WORKING ORDER
The unit should be inspected annually by a qualified
service agency.

shock or death.
ANNUAL MAINTENANCE
Routine inspection and maintenance procedures are the
responsibility of the user and are outlined below.
1. Before inspecting unit:
a. Turn room thermostat to lowest or off setting.
ROUTINE MAINTENANCE
1. Air Filters – Check the condition at least monthly
when the unit is in use, and replace as necessary.
2. Lubrication Requirements – The indoor circulating
air blower motor and outdoor circulating air fan
motor are permanently lubricated and require no reoiling. The combustion air blower motor requires no
re-oiling.
WARNING
Turn off electrical power supply to prevent
injury from moving parts or electric shock.
b. Turn off equipment gas shut off valve.
c. Wait for unit to cool if it was recently
operating.
d. Turn off electrical power to unit.
2. Inspect the following:
a. Vent terminal and combustion air intake
terminal. Make sure both are free from
obstructions.
b. Vertical Vent Applications – Inspect venting
system. Make sure system has no holes, is
physically sound and free from obstructions.
c. Make sure the supply and return air flange
sleeves or duct work are securely fastened to
unit and physically sound.
d. Supply and return grilles must be open and
free from obstructions.
e. Inspect to make sure the unit is securely
fastened to the wall. Seal any possible leaks
between unit and wall with appropriate
exterior sealing material.
f. Inspect burners, heat exchanger, induced
draft blower, and induced draft blower
collector box. There must be no obvious
signs of deterioration.
g. Inspect all electrical connections and wiring.
h. Check all gas piping for leaks with soap
solution used to detect leaks.
i. Inspect, clean, and repair as needed the entire
blower assembly, air filters, draft inducer,
cooling coils, and vent options (if installed).

ROUTINE INSPECTION
1. Inspect the physical support of the unit annually to
make sure it is securely fastened to the building.
Also look for any obvious signs of deterioration.
2. Inspect the main burners at the beginning of each
heating season and clean as necessary.
3. Inspect the vent terminal and combustion air intake
hood for any obvious deterioration, to make sure it is
free and clear of any obstructions.
29. REPLACEMENT PARTS
WARNING
Use replacement parts listed in Replacement
Parts list. Failure to do so could cause
improper furnace operation, resulting in
property damage, personal injury, or death.
Replacement parts for the gas/electric units are
available through local distributors.
A replacement parts list manual is supplied with each
unit. When ordering parts or making inquires
pertaining to any of the units covered by these
instructions, it is very important to always supply the
complete model number and serial number of the unit.
This is necessary to assure that the correct parts (or an
approved alternate part) are issued to the service
agency.
30. SEQUENCE OF OPERATION –
HEATING
On a call for heat from the thermostat, the induced draft
blower is energized. Once sufficient draft is
established, the pressure switch contacts close and the
ignition system is energized. The direct spark ignitor
will be energized allowing gas to flow. At the same
time the main valve is energized, a 30-second blower
delay timer is activated.
After this delay, the heating speed blower relay
energizes. The blower will begin operating and remain
in operation until the set delay time after the call for
heat has been satisfied. (See Table 15 for selectable
blower off time delays.) This timing sequence
guarantees blower on, blower off operation.
This unit is equipped with a flame rollout switch which
is wired in series with the control circuit. This is a
manual reset switch and is used for the purpose of
preventing possible fire hazard in the event of a system
malfunction. If this switch has opened the control
circuit, there could be a possible system malfunction.
Some of the conditions that might cause a rollout to
occur are blockage or sooting of primary heat
exchanger, overfiring of furnace due to improper main
burner orifices or incorrect manifold pressure,
insufficient combustion air, or installation deficiencies
with respect to return air duct design or sizing.
Once the problem has been resolved, reset the switch by
pressing down on the reset button on top of the switch.
See Figure 17 for additional information.
31. SEQUENCE OF OPERATION –
COOLING
On a call for cooling from the room thermostat, the high
speed blower relay will be energized as well as the
compressor contactor. Following termination of the
cooling cycle, the blower motor will continue to run for
one minute.
See Figure 17 for additional information.
The unit may be equipped with a low ambient control
for lower outdoor temperature operation in the cooling
mode. If equipped with this optional control the
condenser fan will not operate immediately upon
compressor start-up, and will cycle on and off until the
condensing pressure remains above PSIG.

32. INDOOR BLOWER OPERATION
460 VOLT BLOWER MOTOR SPEED CHANGE
All models have multiple speed direct drive blower
motors. If supply and return ducts are connected to the
unit, the ducts must be of adequate size. Refer to the
appropriate blower tables. See Tables 10, 11, 12, 13,
14 and 15 for maximum static pressures acceptable.
Note the minimum CFM for cooling operation.
Field changeover from the factory blower motor speed
settings can require change several different motor
leads, the addition or deletion of a wire.
Refer to blower motor wiring options as shown below
for the correct wiring of the blower motor for the
application involved.
If voltage and duct design permit, (see blower tables)
single speed operation can be achieved as follows:
230 VOLT BLOWER MOTOR SPEED CHANGE
1. Disconnect main power supply to unit.
2. Remove and tape off the unwanted indoor motor
speed tap from the heat or cool terminal on the
furnace control board.
3. Next install a jumper wire with multiplier between
heat and cool terminal and attach desired blower
motor speed to other side of multiplier.
4. Energize the system in cooling and heating modes
and check for proper blower operation.

34. REFRIGERANT CHARGE
The correct system R-22 charge is shown on the unit
rating plate. Optimum unit performance will occur
with a refrigerant charge resulting in a suction line
temperature (6" from compressor) as shown in
Table 18.
The suction line temperatures in Table 18 are based
upon 80 degrees F dry bulb / 67 degree wet bulb (50%
R.H.) temperature and rated airflow across the
evaporator during cooling cycle.
Total system charge for these models can be found in
Table 1.

NATURAL GAS MODELS ONLY
Model numbers designated with an “N” are designed
for low NOx emissions which comply with all
California Air Quality Management District regulations
for nitrogen oxide emission levels. Refer to Figure 22
for NOx insert information.
* * IMPORTANT * *
For propane (LP) conversions the NOx
reduction screen inserts shown below must
be removed. This is accomplished by
removing the burner box assembly and
removing the NOx screens. Reassemble unit
properly before firing. Failure to remove the
NOx screens can result in improper operation
and malfunction of the burner system.
