General Layout at the Unit
Natural Gas Connection
Refer to the above figure for the general layout at the unit. The
following rules apply:
1. Use black iron or steel pipe and fittings for the supply piping.
2. Use pipe joint compound on male threads only. Pipe joint
compound must be resistant to the action of the fuel used.
3. Use ground joint unions.
4. Install a drip leg to trap dirt and moisture before it can enter
the gas valve. The drip leg must be a minimum of three
inches long.
5. Use two pipe wrenches when making connection to the gas
valve to keep it from turning.
6. Install a manual shut-off valve in a convenient location (within
six feet of unit) between the meter and the unit.
7. Tighten all joints securely.
8. The unit must be connected to the building piping by one of
the following methods:
• Rigid metallic pipe and fittings
• Semirigid metallic tubing and metallic fittings (Aluminum
alloy tubing must not be used in exterior locations)
• Listed gas appliance connectors used in accordance with
the terms of their listing that are completely in the same
room as the equipment
• In the prior two methods above the connector or tubing
must be protected from physical and thermal damage.
Aluminum alloy tubing and connectors must be coated to
protect against external corrosion when in contact with
masonry, plaster or insulation or are subject to repeated
wettings by liquids (water - not rain water, detergents or
sewage).
PROPANE GAS INSTALLATIONS
WARNING
TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO FIRE
OR EXPLOSION CAUSED BY A PROPANE GAS LEAK, INSTALL A GAS
DETECTING WARNING DEVICE. SINCE RUST CAN REDUCE THE LEVEL
OF ODORANT IN PROPANE GAS, A GAS DETECTING WARNING DEVICE
IS THE ONLY RELIABLE WAY TO DETECT A PROPANE GAS LEAK.
CONTACT A LOCAL PROPANE GAS SUPPLIER ABOUT INSTALLING A
GAS DETECTING WARNING DEVICE.
IMPORTANT NOTE: Propane gas conversion kits must be
installed to convert units to propane gas. See High Altitude Gas
Orifice chart for kit part number for this model.
All propane gas equipment must conform to the safety standards
of the National Board of Fire Underwriters (See NBFU Manual
58).
For satisfactory operation, propane gas supply pressure must
be 10 inch w.c. at the unit manifold with all gas appliances in
operation. Maintaining proper gas pressure depends on three
main factors:
1. Vaporization rate, which depends on (a) temperature of the
liquid, and (b) wetted surface area of the container or
containers.
2. Proper pressure regulation.
3. Pressure drop in lines between regulators, and between
second stage regulator and the appliance. Pipe size required
6
will depend on length of pipe run and total load of all
appliances.
standard commercial compounds, special pipe dope must be
used. Shellac based compounds resistant to the actions of
liquefied petroleum gases such as Gasolac®, Stalactic®, Clyde’s®
or John Crane® are satisfactory. The figure below shows a typical

CONDENSATE DRAIN
HIGH STATIC OR DOWN-DISCHARGE INSTALLATION
IMPORTANT: Elevated internal static pressure can cause
condensate to be drawn out of the drain pan and into the return air
plenum. For gas package units and down discharge installations
experiencing total external pressure of 0.30” w.c. or greater, add a
splash baffle. It will prevent condensate from seeping over into the
return air plenum in high static applications. The baffles are factory
installed in all large chassis gas/electric package units. Contact your
distributor for the correct splash baffle for your model.
CONDENSATE DRAIN CONNECTION
These units are equipped with a built-in trap and do not require
an external trap.
To avoid double trapping and an overflowing drain pan, soft
plastic drain lines are not recommended.

NORMAL SEQUENCES OF OPERATION
HEATING
This unit is equipped with an ignition control that automatically
lights the main burner. DO NOT attempt to light the main burners
by any other method.
1. Thermostat calls for heat. The induced draft blower energizes
for a 15-second pre-purge.
2. The spark igniter and gas valve energizes for seven seconds.
NOTE: The igniter produces a very intense electrical spark
that ignites the gas.
3. The 30-second HEAT FAN ON delay time begins.
4. The unit delivers heat to the conditioned space until the
thermostat is satisfied.
5. The gas valve deenergizes. The induced draft blower
continues operation for a 29-second post-purge.
6. Ignition control begins timing the HEAT FAN OFF delay. This
allows any additional heat in the heat exchanger to be
transferred to the conditioned space. After the HEAT FAN
OFF delay time has elapsed, the blower will deenergize.
Models with a PSC (Permanent Split Capacitor) circulator blower
motor have an adjustable HEAT FAN OFF delay of 90/120/ 150/
seconds OR 60/90/120/180 seconds. Models with variable
speed motor (ECM) have a fixed HEAT FAN OFF delay of 120
seconds.
HEATING STARTUP
Heat Anticipator Setting
Set the heat anticipator on the room thermostat to 0.4 amps to
obtain the proper number of heating cycles per hour and to
prevent the room temperature from overshooting the room
thermostat setting.
Rollout Protection Control
The rollout protection device opens, cutting power to the gas
valve, if the flames from the burners are not properly drawn into
the heat exchanger. The rollout protection device is located on
the burner bracket (see figure below). The reason for elevated
temperatures at the control should be determined and repaired
prior to resetting this manual reset control.
Rollout Protection
Rollout Protection Device
COOLING
1. Thermostat calls for cooling. The compressor and outdoor
fan are energized.
2. Approximately seven seconds later, the indoor fan starts.
NOTE: Models with a variable speed motor (ECM) do not
have a seven-second COOL FAN ON delay. The motor
“ramps” up to full speed over a 30-second period.
3. The unit will deliver cooling to the conditioned space until
the thermostat is satisfied.
4. The compressor and outdoor fan will be deenergized when
the thermostat opens.
5. The indoor fan continues to run for approximately 30 seconds
after the thermostat is satisfied. This allows additional cooling
from the indoor coil to be transferred to the conditioned
space. Then, the indoor fan stops.
WARNING
TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO FIRE
OR EXPLOSION, A QUALIFIED SERVICER MUST INVESTIGATE THE REASON FOR
THE ROLLOUT PROTECTION DEVICE TO OPEN BEFORE MANUALLY RESETTING
THE ROLLOUT PROTECTION DEVICE.
Secondary Limit Control
A second limit control is placed on the blower scroll. This control
will open due to elevated temperature caused by the blower
failing. The reason for elevated temperatures at the control
should be determined and repaired prior to resetting. The
secondary limit control is located on the top of the blower scroll
assembly (see figure below).
If the power to the unit is interrupted during the heating cycle, it
may cause the secondary limit to trip. Once the blower
compartment temperature drops below the limit reset
temperature, the limit will automatically reset.
FAN ONLY
1. Thermostat calls for FAN ONLY by energizing “G”.
2. Approximately seven seconds later, the indoor fan starts.
NOTE: Not all models will have a “7-Second ON” indoor
fan start delay or an “OFF” delay in continuous fan mode.
3. The indoor fan continues to run for approximately 30 seconds
after “G” is deenergized.

Min. 5.0" W.C., Max. 10.0" W.C.
Min. 11.0" W.C., Max. 13.0" W.C.
NOTE: Inlet Gas Pressure Must Not Exceed the Maximum Value
Shown.
Temperature Rise Check
Check the temperature rise through the unit by placing
thermometers in supply and return air registers as close to the
unit as possible. Thermometers must not be able to sample
temperature directly from the unit heat exchangers, or false
readings could be obtained.
1. All registers must be open; all duct dampers must be in their
final (fully or partially open) position and the unit operated
for 15 minutes before taking readings.
2. The temperature rise must be within the range specified on
the rating plate.
NOTE: Air temperature rise is the temperature difference
between supply and return air.
With a properly designed system, the proper amount of
temperature rise will normally be obtained when the unit is
operated at rated input with the recommended blower speed.
If the correct amount of temperature rise is not obtained, it may
be necessary to change the blower speed. A higher blower
speed will lower the temperature rise. A slower blower speed
will increase the temperature rise.
NOTE: Blower speed MUST be set to give the correct air
temperature rise through the unit as marked on the rating plate.
If operating pressures differ from above, make necessary
pressure regulator adjustments, check piping size, etc., and/or
consult with local utility.
Manifold Pressure Check
A ”U” Tube manometer having a scale range from 0 to 12 inches
of water should be used for this measurement. The manifold
pressure must be measured with the burners operating.
Honeywell Model VR8205, White-Rodgers Models 36E22/
36F22:
A tapped opening is provided in the gas valve to facilitate
measurement of the manifold pressure.
White Rodgers Model 36G22:
Using a 3/32 inch hex wrench, loosen the outlet pressure tap
screw 1 turn only (DO NOT REMOVE). Attach a length of 5/16
inch hose to the outlet pressure tap boss. Connect the 5/16
inch hose to a water manometer or other adequate gauge.
To adjust the pressure regulator, remove the adjustment screw
or cover on the gas valve. Turn out (counterclockwise) to
decrease pressure, turn in (clockwise) to increase pressure.
Only small variations in gas flow should be made by means of
the pressure regulator adjustment. In no case should the final
manifold pressure vary more than plus or minus 0.3 inches water
column from the specified nominal pressure. Any major changes
in flow should be made by changing the size of the burner
orifices. The measured input rate to the furnace must not exceed
the rating specified on the unit rating plate.
For natural gas, the manifold pressure must be between 3.2
and 3.8 inches water column (3.5 nominal).
For propane gas, the manifold pressure must be between 9.7
and 10.3 inches water column (10.0 nominal).
External Static Pressure Check
The total external static pressure must be checked on this unit
to determine if the airflow is proper.
Limit Check
Check limit control operation after 15 minutes of operation by
blocking the return air grille(s).
1. After several minutes the main burners must go OFF. Blower
will continue to run.
2. Remove air restrictions and main burners will relight after a
cool down period of a few minutes.
Adjust the thermostat setting below room temperature.
1. Main burners must go OFF.
2. Circulating Air Blower will continue to run for selected HEAT
FAN OFF delay.
Gas Input (Natural Gas Only) Check
NOTE: On outdoor equipment, the gas input will vary with the
temperature of the gas. Rated input will be obtained at
approximately 10° F. With warmer ambient and gas
temperatures, the input will decrease. Example: At 70° F the
input will decrease 12%.
To measure the gas input using the gas meter proceed as
follows:
1. Turn off gas supply to all other appliances except the unit.
2. With the unit operating, time the smallest dial on the meter
for one complete revolution. If this is a 2 cubic foot dial,
divide the seconds by 2; if it is a 1 cubic foot dial, use the
seconds as is. This gives the seconds per cubic foot of gas
being delivered to the unit.
3. INPUT=GAS HTG VALUE x 3600 / SEC. PER CUBIC FOOT
Example: Natural gas with a heating value of 1000 BTU per
cubic foot and 34 seconds per cubic foot as determined by
Step 2, then:
Input = 1000 x 3600 / 34 = 106,000 BTU per Hour. NOTE:
BTU content of the gas should be obtained from the gas
supplier. This measured input must not be greater than
shown on the unit rating plate.

External Lockout
D5
R25
An external lockout occurs if the integrated ignition control
determines that a measurable combustion cannot be established
within three (3) consecutive ignition attempts. If flame is not
established within the seven (7) second trial for ignition, the
gas valve is deenergized, 15 second inter-purge cycle is
completed, and ignition is re-attempted. The control will repeat
this routine three times if a measurable combustion is not
established. The control will then shut off the induced draft
blower and go into a lockout state.
If flame is established but lost, the control will energize the
circulator blower at the heat speed and then begin a new ignition
sequence. If flame is established then lost on subsequent
attempts, the control will recycle for four (4) consecutive ignition
attempts (five attempts total) before locking out.
The diagnostic fault code is 1 flash for a lockout due to failed
ignition attempts or flame dropouts. The integrated control will
automatically reset after one hour, or it can be reset by removing
the thermostat signal or disconnecting the electrical power
supply for five seconds.
Important: If you have to frequently reset your gas/electric
package unit, it means that a problem exists that should be
corrected. Contact a qualified servicer for further information.

Pressure Switch Stuck Open
Compressor Protection Devices
A pressure switch stuck open can be caused by a faulty pressure
switch, faulty wiring, a disconnected or damaged hose, a blocked
or restricted flue, or a faulty induced draft blower.
If the control senses an open pressure switch during the prepurge cycle, the induced draft blower only will be energized. If
the pressure switch opens after ignition has begun the gas valve
is deenergized, the circulator blower heat off cycle begins, and
the induced draft blower remains on. The diagnostic fault code
is two flashes.
The compressor includes components which are designed to
protect the compressor against abnormal operating conditions.

If a primary, auxiliary, or rollout limit switch opens, the gas valve
is immediately deenergized, the induced draft and air circulating
blowers are energized. The induced draft and air circulator
blowers remain energized until the limit switch recloses. The
diagnostic fault code for an open limit is four (4) flashes.
A primary limit will open due to excessive supply air
temperatures. This can be caused by a dirty filter, excessive
duct static, insufficient air flow, or a faulty limit. Check filters,
total external duct static, blower motor, blower motor speed tap
(see wiring diagram), and limit. This limit will automatically reset
once the temperature falls below a preset level.
An automatic reset auxiliary limit is located on the circulator
blower scroll. A dirty filter, excessive duct static, insufficient air
flow, a faulty limit, or a failed circulator blower can cause this
limit to open. Check filters, total external duct static, circulator
blower motor, blower motor speed tap (see wiring diagram),
and limit. An interruption in electrical power during a heating
cycle may also cause the auxiliary limit to open. The secondary
limit is located on top of the circulator blower assembly (see
TROUBLESHOOTING
ABNORMAL OPERATION - HEATING
The following presents probable causes of questionable unit
operation. Remove the control box access panel and note the
number of diagnostic LED flashes. Refer to Diagnostic Indicator
Chart for an interpretation of the signal and to this section for
an explanation.
Internal Lockout
If the integrated ignition control in this unit encounters an internal
fault, it will go into a “hard” lockout and turn off the diagnostic
14
Secondary Limit Control figure).
If the burner flames are not properly drawn into the heat
exchanger, the flame rollout protection device will open. The
rollout limit is a manual reset limit located on the burner bracket.
The cause of the flame rollout must be determined and corrected
before resetting the limit. Possible causes are restricted or
blocked flue passages, blocked or cracked heat exchanger, a
failed induced draft blower, or insufficient combustion air.
Important: If a limit opens five (5) times within a single
call for heat, the ignition control will go into a 30-minute lockout.
Only the air circulator blower remains on during this lockout.
The diagnostic fault code for this condition is “8” flashes and
the control automatically resets after 30 minutes. A dirty filter is
the most likely cause for the fault.
operation, the ignition control will delay output to the compressor
contactor for three minutes from the time power is restored.
(Compressor is off a total of three minutes). The diagnostic
LED will flash six (6) times to indicate the compressor contactor
output is being delayed.
NOTE: Some electronic thermostats also have a built-in compressor
short cycle timer that may be longer than the three minute delay
given above. If you are using an electronic thermostat and the
compressor has not started after three minutes, wait an additional
five minutes to allow the thermostat to complete its short cycle delay
time.
MAINTENANCE
Flame Detected with Gas Valve Closed
Have the gas heating section of the unit checked at least once
a year before the heating season begins, to be sure that the
combustion air inlet and flue outlet hoods are not blocked by
debris, which would prevent adequate combustion air and a
properly operating vent system.
If flame is sensed with the gas valve deenergized, the
combustion and air circulator blowers are energized. The
diagnostic fault code is five (5) flashes for this condition. The
control can be reset by removing the power supply to the unit or
it will automatically reset after one hour. Miswiring is the probable
cause for this fault.
WARNING
Low Flame Sensor Current
If the flame sense current drops below approximately one
microamp DC, the diagnostic LED will flash seven (7) times.
The control will function normally until it can no longer sense
flame. If this fault code is encountered, have a qualified service
technician remove the sensor and clean it with steel wool.
TO AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK,
DISCONNECT ELECTRICAL POWER BEFORE PERFORMING ANY MAINTENANCE.
REPLACING OR CLEANING FILTER
A return air filter is not supplied with this unit; however, there
must be a means of filtering all of the return air. The filter(s)
may be located in the return air duct(s), or return air filter grille(s).
Consult with your installing dealer for the actual location of the
return air filter(s) for your unit.
Dirty filters are the most common cause of inadequate heating
or cooling performance. Filter inspection should be made at
least every two months; more often if necessary because of
local conditions and usage.
Dirty throwaway filters should be discarded and replaced with a
new, clean filter. Dirty permanent filters should be washed with
water, thoroughly dried and sprayed with a filter adhesive before
being reinstalled. (Filter adhesives may be found at many
hardware stores.) Permanent filters should last several years.
However, should one become torn or uncleanable, it should be
replaced.
Gas Valve Energized When It Should Be OFF
Some models utilize an ignition control that recognizes voltage
present at the gas valve when the gas valve should be off. If
the ignition control senses this fault, it will lockout all functions
except continuous fan. This fault is indicated by (9) flashes.
Possible causes are miswiring, shorts in the wire harness, or
corrosion at the burners. Check and correct wiring if required.
Inspect and clean burners if required. Power to the unit must
be removed in order to reset the control from lockout.
ABNORMAL OPERATION - COOLING
Short Cycle Compressor Delay
The automatic ignition control has a built-in feature that prevents
damage to the compressor in short cycling situations. In the
event of intermittent power losses or intermittent thermostat

MAINTAINING CABINET FINISH
MAIN BURNER FLAME (QUALIFIED SERVICER ONLY)
Use a fine grade automotive wax on the cabinet finish to maintain
the finish’s original high luster. This is especially important in
installations with extended periods of direct sunlight.
Flames should be stable, soft and blue (dust may cause orange
tips but must not be yellow). The flames must extend directly
outward from the burner without curling, floating or lifting off.
CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)
The coil with the outside air flowing over it should be inspected
annually and cleaned as frequently as necessary to keep the
finned areas free of lint, hair and debris.
CONDENSER, EVAPORATOR, AND INDUCED DRAFT MOTORS
Bearings on the air circulating blower motor, condenser motor
and the combustion fan motor are permanently lubricated. No
additional oiling is required.
Check the burner flames for:
1. Good adjustment
2. Stable, soft and blue
3. Not curling, floating, or lifting off.
FLAME SENSOR (QUALIFIED SERVICER ONLY)
A drop in the flame sensing signal can be caused by a nearly
invisible coating on the flame sensor. This coating, created by
the fuel or combustion air supply, can be removed by carefully
cleaning the flame sensor with steel wool.
NOTE: After cleaning, the microamp signal should be stable
and in the range of 4 - 6 microamps DC.

ADJUSTMENT.
CONTACT A QUALIFIED SERVICER AT ONCE IF AN ABNORMAL
FLAME SHOULD DEVELOP.
At least once a year, prior to or during the heating season, make
a visual check of the burner flames.
NOTE: This will involve removing and reinstalling the heat
exchanger door on the unit, which is held by two screws. If you
are uncertain about your ability to do this, contact a qualified
servicer.
If a strong wind is blowing, it may alter the airflow pattern within
the unit enough that an inspection of the burner flames is not
possible.
Flame Sensor Location
FLUE PASSAGES (QUALIFIED SERVICER ONLY)
At the start of each heating season, inspect and, if necessary,
clean the unit flue passage.
CLEANING BURNERS
1. Shut off electric power and gas supply to the unit.
2. Remove the screws holding the burner retention bracket in
place.
NOTE: On some models it will be necessary to remove the
manifold instead of a burner retention bracket. In such a
case, remove the manifold and rotate each burner
counterclockwise to remove.
Cleaning Flue Passages (Qualified Servicer Only)
1. Shut off electric power and gas supply to the unit.
2. Remove burner assembly by disconnecting the gas line and
removing the manifold bracket from the partition panel.
3. Remove the flue from the induced draft blower and the
collector box from the partition panel.
4. The primary heat exchanger tubes can be cleaned using a
round wire brush attached to a length of high grade stainless
steel cable, such as drain cleanout cable. Attach a variable
speed reversible drill to the other end of the spring cable.
Slowly rotate the cable with the drill and insert it into one of
the primary heat exchanger tubes. While reversing the drill,
work the cable in and out several times to obtain sufficient
cleaning. Use a large cable for the large tube, and then repeat
the operation with a small cable for the smaller tube. Repeat
for each tube.
5. When all heat exchanger tubes have been cleaned, replace
the parts in the reverse order in which they were removed.
6. To reduce the chances of repeated fouling of the heat
exchanger, perform the steps listed in “Startup, Adjustments,
and Checks”.
