• The flue outlet hood must be at least 12 inches from any opening through which flue gases could enter a building, and at least
three feet above any forced air inlet located within ten feet. The economizer/manual fresh air intake/motorized fresh air
intake and combustion air inlet mounted on the unit are not affected by this restriction.

• To avoid possible corrosion of the heat exchanger, do not locate the unit in an area where the outdoor air (i.e. combustion
air for the unit) will be frequently contaminated by compounds containing chlorine or fluorine. Common sources of such
compounds include swimming pool chemicals and chlorine bleaches, paint stripper, adhesives, paints, varnishes, sealers,
waxes (which are not yet dried) and solvents used during construction and remodeling. Various commercial and industrial
processes may also be sources of chlorine/fluorine compounds.

• To avoid possible illness or death of the building occupants, do NOT locate outside air intake device (economizer, manual fresh
air intake, motorized fresh air intake) too close to an exhaust outlet, gas vent termination, or plumbing vent outlet. For
specific distances required, consult local codes.

• Allow minimum clearances from the enclosure for fire
protection, proper operation, and service access (see
appendix). These clearances must be permanently
maintained.

• The combustion air inlet and flue outlet hoods on the unit
must never be obstructed. If used, do not allow the
economizer/manual fresh air damper/ motorized fresh air
damper to become blocked by snow or debris. In some
climates or locations, it may be necessary to elevate the
unit to avoid these problems.

• Damper must be in open position when appliance main
burner(s) is operating.

Le registre doit être ouvert lorsque tout brûleur principal
de l’appareil est en état de fonctionnement.

• When the unit is heating, the temperature of the return air
entering the unit must be between 50° F and 100° F.

• Units manufactured on or after May 1, 2017 are not permitted
to be used in Canada for heating of buildings or structures

Propane Min. 11.0" W.C., Max. 13.0" W.C.

Inlet Gas Pressure Must Not Exceed the Maximum Value Shown in Table Above.

The minimum supply pressure should not vary from that shown in the table above because this could prevent the unit from having
dependable ignition. In addition, gas input to the burners must not exceed the rated input shown on the rating plate. Over firing
of the unit could result in premature heat exchanger failure.

HIGH ALTITUDE DERATE (U.S. INSTALLATIONS ONLY)

IMPORTANT NOTE: Installation of this gas/electric package unit at altitudes above 2000 ft (610 m) shall be made in accordance with

the Listed High Altitude Conversion Kit.
L’installation de ce générateur de chaleur à des altitudes supérieures à 2000 pi (610 m) doit être effectuée conformément aux

instructions accompagnant la trousse de conversion pour haute altitude fournie avec cet appareil.
The gas/electric units naturally derate with altitude. Do not attempt to increase the firing rate by changing orifices or increasing

the manifold pressure. This can cause poor combustion and equipment failure. At all altitudes, the manifold pressure must be
within 0.3 inches W.C. of that listed on the nameplate for the fuel used. At all altitudes and with either fuel, the air temperature rise
must be within the range listed on the unit nameplate.

Refer to the Installation Manual provided with the LP kit for conversion from natural gas to propane gas and for altitude adjustments.
Use HA02 for installations above 2000’.

Proper Piping Practice
NOTE: The unit gas supply entrance is factory sealed with plugs.

Keep plugs in place until gas supply is ready to be installed.
Once ready, replace the plugs with the supplied grommets and
install gas supply line.

There will be air in the gas supply line after testing for leaks on
a new installation. Therefore, the air must be bled from the line
by loosening the ground joint union until pure gas is expelled.
Tighten union and wait for five minutes until all gas has been
dissipated in the air. Be certain there is no open flame in the
vicinity during air bleeding procedure. The unit is placed in op­eration by closing the main electrical disconnect switch for the
unit.

Propane Gas Installations

IMPORTANT NOTE: Propane gas conversion kits must be installed
to convert units to propane gas. Refer to the gas piping section
for the correct LP kit for conversion.

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 within 9.7 - 10.3 inches W.C. at the 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 will depend
on length of pipe run and total load of all appliances.

WIRING

NOTE: All wiring should be made in accordance with the National Electrical Code.

Consult your local Power Company to determine the availability of sufficient power to operate the unit. Check the voltage,
frequency, and phase at the power supply to ensure it corresponds to the unit’s RATED VOLTAGE REQUIREMENT.
In accordance with the N.E.C. or local codes, install a branch circuit fused disconnect near the unit. Determine wire sizes and
overcurrent protection from the unit nameplate ampacity and in accordance with the Minimum Filter Size or the N.E.C. The wiring
should never be sized smaller than is recommended by either of these two sources.
Fuses smaller than that recommended on the rating plate could result in unnecessary fuse failure or service calls. The use of
protective devices of larger size than indicated could result in extensive damage to the equipment. The manufacturer bears no
responsibility for damage caused to equipment as result of the use of larger than is recommended size protective devices.
All units have undergone a run test prior to packaging for shipment. This equipment has been started at minimum rated voltage and
checked for satisfactory operation. Do not attempt to operate this unit if the voltage is not within the minimum and maximum
voltages shown on nameplate.
All exterior wiring must be within approved weatherproof conduit. The unit must be permanently grounded in accordance with
local codes, or in absence of local codes, with N.E.C. ANSI/
NFPA NO. 70-1984 or latest edition by using ground lug in the
control box.
Fuses or HACR type circuit breakers may be used where codes
permit.
IMPORTANT NOTE: Some single phase units are equipped with a
single-pole contactor. Exercise caution when servicing as only
one leg of the power supply is broken with the contractor.

HIGH VOLTAGE WIRING

The unit transformer is factory connected for 230V operation. If
the unit is to operate on 208V, reconnect the transformer primary
lead as shown on the unit wiring diagram. The induced draft blower
on some models is equipped with a low speed 230V lead (blue) and
a low speed 208V lead (black). If equipped, connect the induced
draft blower low speed 208V lead (black) in place of the low speed
230V lead (blue). Place the unused 230V lead on the “PARK” termi­nal located on ignition control.

• Single Phase. Connect two leads to terminals L1 & L2 in
the electrical control section, using wire sizes specified in
wiring table.

ALTERNATE: A 1-stage cool/2-stage heat pump thermostat with OTDFPKG-01 outdoor tem-

perature sensor kit.
IMPORTANT NOTE: For optimal performance, an outdoor temperature sensor should be used

with the control thermostat to determine when the unit switches from heat pump mode to
gas mode. The unit is compatible with a standard heat pump thermostat with a minimum of 1
cool - 2 heat. If an outdoor sensor is not installed, the gas will not ignite until the control
thermostat calls for a 2nd stage of heat.

INTERNAL WIRING

A diagram detailing the internal wiring of this unit is located on the Goodman labeled access panel. If any of the original wire
supplied with the appliance must be replaced, the wire gauge and insulation must be the same as the original wiring.

1. For branch circuit wiring (main power supply to unit disconnect), the minimum wire size for the length of run can be
determined using the circuit ampacity found on the unit rating plate and the table below. From the unit disconnect to the
unit, the smallest wire size allowable may be used for the ampacity, as the disconnect must be in sight of the unit.

2. Wire size based on 60°C rated wire insulation and 30°C Ambient Temperature (86°F).

3. For more than three conductors in a raceway or cable, see the N.E.C. for derating the ampacity of each conductor.

11

For unit protection, use a fuse or HACR circuit breaker that is in
excess of the circuit ampacity, but less than or equal to the
maximum overcurrent protection device. DO NOT EXCEED THE
MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON UNIT DA T A PLA TE.
All line voltage connections must be made through weather­proof fittings. All exterior power supply and ground wiring must
be in approved weatherproof conduit. Low voltage wiring from
the unit control panel to the thermostat requires coded cable. See below for ground level and rooftop wiring.

CIRCULATING AIR AND FILTERS
A

IRFLOW CONVERSION

Units can easily be converted from horizontal to down-discharge airflow delivery.
In down-discharge or high static installations, the installer should measure the
total external static and review the blower performance charts before perform­ing the installation. In some installations it will be necessary to change the blower
speed to provide proper air flow.

HORIZONTAL AIR FLOW

Single phase models are shipped without horizontal duct covers. If needed, these
kits may be ordered through Goodman’s Service Parts department.

Down Discharge Applications

Cut insulation around bottom openings and remove panels from the bottom of
the unit, saving the screws holding the panels in place.
NOTE: Single phase models require installation of horizontal duct kit
#20464501PDGK (medium chassis) and #20464502PDGK (large chassis).

Duct Cover Installation

DUCTWORK

Duct systems and register sizes must be properly designed for the C.F.M. and external static pressure rating of the unit. Ductwork
should be designed in accordance with the recommended methods of Air Conditioning Contractors of America Manual D (Residen­tial) or Manual Q (Commercial). All ductwork exposed to the outdoors must include a weatherproof barrier and adequate insulation.
A duct system should be installed in accordance with Standards of the National Board of Fire Underwriters for the Installation of Air
Conditioning, Warm Air Heating and Ventilating Systems. Pamphlets No. 90A and 90B.

12

The supply duct from the unit through a wall may be installed without clearance. However, minimum unit clearances as shown in the
appendix must be maintained. The supply duct should be provided with an access panel large enough to inspect the air chamber
downstream of the heat exchanger. A cover should be tightly attached to prevent air leaks.
For duct flange dimensions on the unit refer to the Unit Dimension illustration in the appendix.
For down-discharge applications, the ductwork should be attached to the roof curb prior to installing the unit. Ductwork dimen­sions are shown in the roof curb installation manual.
If desired, supply and return duct connections to the unit may be made with flexible connections to reduce possible unit operating
sound transmission.

FILTERS

Even though a return air filter is not supplied with this unit,
there must be a means of filtering all return air. All units may be
externally filtered.
Refer to the unit filter size chart in the appendix for filter size
information.
Filters installed external to the unit should be sized in accordance with their manufacturer recommendations. A throwaway filter
must be sized for a maximum face velocity of 300 feet per minute.

Filter Installation
IMPORTANT NOTE: When installing a filter, the air flow arrows on the filter must point toward the circulator blower.

VENTING

NOTE: Venting is self-contained. Do not modify or block.

UTDOOR THERMOSTAT

For optimal performance, a dual fuel thermostat with an outdoor tem­perature sensor should be used. TSTATGTS3275 (Emerson Dual Fuel thermostat) with TSTATTSORS (outdoor temperature sensor) is
recommended.

This will allow the installer to control when the unit switches from heat pump to gas heat based on a set point entered into the
thermostat. It is recommended to set the thermostat between 35° - 45°F, depending on regional climate and energy rates.

Drain Connection

OPTIONAL OUTDOOR THERMOSTAT (OTDFPKG-01)

The outdoor thermostat is an optional accessory that can be set from 0 - 45°F and is set inside a “birdhouse” enclosure. This
enclosure will be mounted near the blower access panel. The dimples and knock-out are located on the corner posts, providing
ease of installation. Once the thermostat closes, a 24 volt signal is sent to the W1 terminal instead of the Y terminal and the heating
cycle will change from Heat Pump to Gas heating. It is recommended to set the thermostat between 35-45°F depending on regional
climate and energy rates.

HEATING CYCLE (HEAT PUMP)

The heat pump operates in the heating cycle by redirecting refrigerant flow through the refrigerant circuit external to the
compressor. This is accomplished through the reversing valve. Hot discharge vapor from the compressor is directed to the indoor
coil (evaporator on the cooling cycle) where the heat is removed, and the vapor condenses to liquid. It then goes through the
expansion device to the outdoor coil (condenser on the cooling cycle) where the liquid is evaporated, and the vapor goes to the
compressor.
When the solenoid valve coil is energizing for cooling, the piston in the reversing valve to the low pressure (high pressure) reverse
positions in the reversing valve. In addition to a reversing valve, a heat pump is equipped with an expansion device for the indoor
coil, and similar equipment for the outdoor coil is provided with a defrost control system.

HEATING CYCLE (NATURAL GAS/ LP)

1. The Dual Fuel unit will operate in gas heat mode when the thermostat calls for a W-1 or W-2 signal. If outdoor thermostat is
installed, the unit will operate in gas heat when ambient is below set point or the unit receives call for low or high stage gas
heat.

2. Induced draft blower energizes for 15-second pre-purge.

3. A 7-second trial for ignition begins by energizing the low and high stages of the gas valve along with this spark ignition.
NOTE: The igniter produces a very intense electrical spark that ignites the gas.

4. Main burners light and control detects presence of flame.

5. If the call is for low stage heat, the induced draft blower switches from high to low speed and the gas valve from high to low
stage within 5 seconds after the main burners light. If call is for high stage heat, induced draft blower remains at high speed
and high stage gas valve remains open.

NOTE: If a W2 is not used, the control will step to low stage after the main burners light and remain at low stage for 5 or
10 minutes, depending on jumper position. If the jumper is set to none, you will never get a call for high stage heat. If the

call for HEAT remains after the transition delay time expires, the control will transition from low stage to high stage.

6. The 30-second HEAT FAN ON delay time begins after the main burners light.

7. The unit delivers heat to the conditioned space until the thermostat is satisfied.

8. Gas valve(s) de-energizes. The induced draft blower continues operation for a 30-second post-purge.
NOTE: Induced draft blower remains at low speed (or switches from high to low if operating at high stage heat) for the 30-

second post purge.

9. Ignition control begins timing the HEAT FAN OFF delay. There is an adjustable HEAT FAN OFF delay of approximately 90/120/
150/180 seconds (factory set at 150). If the unit is operating at high stage when the call for heat is removed, the blower will
operate for 30 seconds at high heat speed then switch to low heat speed for the remainder of the selected HEAT FAN OFF
delay.

NOTE: After the HEAT FAN OFF delay time has elapsed, the blower will de-energize. This allows any additional heat in the heat
exchanger to be transferred to the conditioned space.

14

DEFROST CYCLE

NOTE: The defrost board is equipped with a jumper for SmartShift™ defrost technology operation. This operation turns the

compressor off for 30 seconds at defrost initiation and termination. The unit is factory shipped for SmartShift™ defrost technology
operation. To operate unit at rated efficiencies, move the jumper on the defrost board from “DLY” to “NORM”.

During operation the power to the circuit board is controlled by a temperature sensor, which is clamped to a feeder tube enteri ng
the outdoor coil. Defrost timing periods of 30, 60 and 90 minutes may be selected by setting the circuit board jumper to 30, 60 and
90 respectively.

Accumulation of time for the timing period selected starts when the sensor closes (approximately 34°F), and when the wall
thermostat calls for heat. At the end of the timing period, the unit’s defrost cycle will be initiated provided the sensor rem ains
closed.

Upon a call for defrost, the blower will continue to run and the defrost board will send a W1 signal to the ignition control. At the
same time the compressor will stop for 30 seconds, if the SmartShift™ defrost technology delay feature is selected on the defrost
board. At this time, the reversing valve shifts from heat to cool position and condenser fans shut off. The inducer motor will
immediately energize for a 15 second prepurge.

A 7-second trial for ignition begins by energizing the low and high stages of the gas valve along with this spark ignition. Main burners
light and control detects presence of flame. The compressor (after its 30/OFF second delay) restarts in cooling mode to defrost the
condensor coil.

When the sensor opens (approximately 60°F), the defrost cycle is terminated and the timing period is reset. If the defrost cycle is
not terminated due to the sensor temperature, a twelve minute override interrupts the unit’s defrost period. At this time the W1
signal is removed from the ignition control board, the compressor will stop for a 30 second SmartShift™ defrost technology delay (if
selected) and the reversing valve slides back to its normal heat position.

COOLING

1. Thermostat calls for cooling.

2. When the thermostat call is for cooling, the compressor and outdoor fan are energized .

3. The indoor blower will energize approximately 6 seconds later.

4. The unit delivers cooling to the conditioned space until the thermostat is satisfied.

5. The compressor and outdoor fan will be de-energized when the thermostat opens.

6. The indoor blower continues to run at low cool speed for approximately 60 seconds after the thermostat is satisfied. This
allows additional cooling from the indoor coil to be transferred to the conditioned space. Then, the indoor blower is de­energized.

NOTE: A 180-second anti-short cycle is integral to the control and prevents recycling of the compressor.

Cooling Operation
NOTE: Mechanical cooling cannot be reliably provided at ambient temperatures below 50° F.

1. Turn on the electrical power supply to the unit.

2. Place the room thermostat selector switch in the COOL position (or A UTO if available, and if automatic changeover from
cooling to heating is desired).

3. Set the room thermostat to the desired temperature.

FAN ONLY

1. Thermostat calls for FAN ONLY by energizing “G”.

2. The indoor blower is immediately energized at the low heat speed.

3. The indoor blower is immediately de-energized once thermostat call for FAN is removed.

AIR FLOW MEASUREMENT AND ADJUSTMENT

Please review the Duct Work section before proceeding with the airflow measurements and adjustments in this section.

Unit blower curves (see Specification Sheets) are based on external static pressure (ESP per in/W.C.). The duct openings on th e
unit are considered internal static pressure. As long as ESP is maintained, the unit will deliver the proper air up to the maximum
static pressure listed for the CFM required by the application (i.e. home, building, etc.)
In general, 400 CFM per ton of cooling capacity is a rule of thumb. Some applications depending on the sensible and latent capacity
requirements may need only 350 CFM or up to 425 CFM per ton. Check condition space load requirements (from load calculations)
and equipment expanded ratings data to match CFM and capacity.
After unit is set and duct work completed, verify the ESP with a 1-inch inclined manometer with pilot tubes or a Magnahelic gauge
and confirm CFM to blower curves in the Specification Sheets.

NOTE: Never run CFM below 350 CFM per ton, evaporator freezing or poor unit performance is possible.

AIR FLOW ADJUSTMENTS FOR INDOOR BLOWER MOTOR

EEM Motor

Adjust the CFM by changing the 24V low voltage lead at the speed terminal block on the motor. (T1, T2, T3, T4, T5). See Blower
Performance Data in the appendix for airflow delivered at each speed tap.
NOTE: Factory set T1 (G, fan and low stage gas heat), T2 (high stage gas heat, T4 (nominal heat pump / cooling).
T3 is for optional low speed cooling and heat pump. T5 is for optional high speed cooling and heat pump.

START-UP, ADJUSTMENTS, AND CHECKS
H

EATING START-UP ( NATURAL GAS / LP)

This unit is equipped with an electronic ignition device to automatically light the main burners. It also has a power vent blower to
exhaust combustion products.
On new installations, or if a major component has been replaced, the operation of the unit must be checked.
Check unit operation as outlined in the following instructions. If any sparking, odors, or unusual sounds are encountered, shut off
electrical power and check for wiring errors, or obstructions in or near the blower motors.

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. The reason for elevated tem­peratures at the control must be determined and repaired prior to resetting this
manual reset control.

Rollout Protection on Burner Bracket

Rollout Protection

Secondary Limit Control

The secondary limit control is located on the top of the blower scroll assembly. This
control opens when elevated temperatures are sensed. Elevated temperatures at the
control are normally caused by blower failure.
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.

Pre-Operation Checks

1. Close the manual gas valve external to the unit.

2. Turn off the electrical power supply to the unit.

3. Set the room thermostat to its lowest possible setting.

4. Remove the heat exchanger door on the side of the unit by
removing screws.

Gas Input (Natural Gas Only) Check

To measure the gas input use a gas meter and 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.

4. Relight all other appliances turned off in step 1. Be sure all pilot burners are operating.

Main Burner Flame Check

Flames should be stable, soft and blue (dust may cause orange tips but they must not be yellow) and extending directly
outward from the burner without curling, floating or lifting off.

17

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.
External Static Pressure Check

The total external static pressure must be checked on this unit to determine if the airflow is proper.

Blower Speed Adjustments

Refer to the wiring diagram and airflow data in the appendix to
verify speed tap settings.

Depending upon the model, blower speeds are changed at the
indoor blower. The ignition control board has four blower speeds:
LOW HEAT, HI HEAT, LOW COOL and HIGH COOL.

O AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK, REMOVE

T

ELECTRICAL POWER FROM THE UNIT BEFORE CHANGING SPEED TAPS ON THE
BLOWER MOTOR.

WARNING

NOTE: FAN ONLY energizes at LOW HEAT speed.
The *PD14 models are equipped with EEM motors. EEM motors are

constant torque motors with very low power consumption. This
motor is energized by 24VAC. Adjust the CFM for the unit by
changing the 24VAC leads to the speed terminal block on the
motor.

NOTE: Heating airflow must be adjusted to provide the temperature
rise shown on rating plate. A higher speed tap may not provide
more airflow. Blower speeds are programmed to deliver adequate
airflow at rated external static pressure (ESP). Refer to airflow
table provided in the Appendix for details.

Compressor Protection Devices

The compressor includes components which are designed to
protect the compressor against abnormal operating conditions.

Refrigerant Charge Check (Units with Fixed Orifice Devices)

After completing airflow measurements and adjustments the unit’s re­frigerant charge must be checked. The unit comes factory charged, but
this charge is based on 325 CFM per ton and minimum ESP per AHRI test
conditions (generally between .15 -.28 ESP). When air quantity or ESP is
different than above, the refrigerant charge must be adjusted to the
proper amount. All package units with fixed orifice devices are charged
using the super heat method at the compressor suction line.
After superheat is adjusted it is recommended to check unit sub-cooling
at the condenser coil liquid line out. For charge adjustments, see super­heat and subcooling charts shown for each model.

MAINTENANCE

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.

FILTER REPLACEMENT OR CLEANING

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.

CABINET FINISH MAINTENANCE

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.

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.

Flame
Sensor

FLAME SENSOR (QUALIFIED SERVICER ONLY)

A drop in the flame current 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.

FLUE PASSAGES (QUALIFIED SERVICER ONLY)

At the start of each heating season, inspect and, if necessary, clean the unit flue passage.

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.

19

Flame Sensor

3. Remove the flue from the induced draft blower and the collector box cover 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 “Start-up, Adjustments, and
Checks”.

MAIN BURNER FLAME (QUALIFIED SERVICER ONLY)

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.

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.

Check the burner flames for:

1. Good adjustment

2. Stable, soft and blue

3. Not curling, floating, or lifting off.

Burner Flame

1. Shut off electric power and gas supply to the unit.

2. Remove the screws securing the manifold to the burner
retention bracket. Remove the manifold and rotate each
burner counterclockwise to remove.

Burner

3. Remove the burners.

4. Use a bottle brush to clean burner insert and inside of the burners.

5. Replace burners and manifold, inspect the burner assembly for proper seating
of burners in retention slots.

Bracket

6. Reconnect electrical power and gas supply.

Manifold

Manifold Assembly

For further information on the yearly inspection, consult the User Manual. It is recommended that a qualified servicer inspect
and service the unit at least once each year.

Turn the unit on at the thermostat. Wait a few minutes, since any dislodged dust will alter the normal flame appearance. Flames
should be predominantly blue and directed into the tubes. They should not be yellow. They should extend directly outward from
the burner ports without curling downward, floating or lifting off the ports.
