INTRODUCTION
WARRANTY AND
RESPONSIBILITIES
It is the sole responsibility of the
home owner to make certain that
the gas furnace has been correctly
set up and converted to the proper
fuel (Propane or Natural gas) and
adjusted to operate properly.
The manufacturer warrants the furnace to be free from defects in
material or workmanship for the
stated time in the warranty agreement (see warranty certificate
packed with the furnace).
However, the manufacturer will not
be responsible for any repair costs
to correct problems due to
improper set-up, improper installation, furnace adjustments, improper
operating procedure by the user,
etc.
Some specific examples of service
calls which cannot be included in
warranty payments are:
1. Converting the furnace to use
another type of gas.
2. Correcting faulty duct work in
the home.
3. Correcting wiring problems in
the electrical circuit to the furnace.
4. Resetting circuit breakers or
other switches.
5. Adjusting the burner air shutter or service calls made to correct problems caused by
improper air adjustment.
6. Correcting problems caused by
improper gas supply pressure
to the furnace.
7. Instructional training on how to
light and operate furnace.
2
8. Furnace problems caused by
installation of air conditioner,
heat pump, or other air quality
device which is not approved.
9. Problems caused by improper
installation of the furnace flue
assembly (roof jack).
10. Adding a roof jack extension
because of unusual wind conditions or snow conditions.
11. Adjusting or calibrating the
thermostat.
12. Problems caused by construction debris which has fallen into
the flue or combustion air
openings.
13. Replacement of fuses.
14. Problems caused by orifice
plugged or restricted by spider
webs.
You should establish a firm understanding of these responsibilities
with your manufactured housing
dealer, service company or gas
supplier so there will be no misunderstanding at a later time.
GAS SUPPLY
The gas supply to your home will
either be Natural Gas or Propane
gas. Your furnace will be factory
equipped to operate on only one of
these two different gases.
A small metal tag secured to the
furnace next to the gas valve will
specify the type of gas your furnace is equipped to use.
If the gas is different from that
specified on the metal tag, the furnace can be converted by following
the instructions on the furnace
safety label inside lower front
panel. Parts for conversion are
contained in the small bag attached
to the gas valve. Be sure the
proper size orifice is used, as specified on the furnace name plate.
The furnace must be
converted by a qualified
technician.
Improper
conversion can cause
unsafe operation, explosion, and/or fire or
asphyxiation.
Natural Gas Operation
The furnace is designed for 7" W.C.
inlet pressure. Pressure is reduced
to 3 1/2" W.C. by the pressure regulator in the gas valve.
Propane Gas Operation
Inlet pressure to the gas valve
must be 11" W.C. When properly
converted to Propane gas, the
pressure is regulated at 10" W.C.
SAFETY INFORMATION
For your safety read before lighting.
1. The first lighting of the furnace
after any home setup must be
performed by a qualified service technician.
2. If this appliance has a pilot that
must be lit by hand, follow
these instructions exactly.
3. BEFORE LIGHTING smell all
around the furnace for gas. Be
sure to smell next to the floor
because some gas is heavier
than air and will settle on the
floor.

SEQUENCE OF
OPERATION
This furnace is equipped with an
electronic control system which
automatically supervises burner
and fan operation. A green indicator light displays during normal
operation. This indicator light also
informs the home owner when certain basic services are needed. In
response to a call for heat by the
room thermostat, the burner is
lighted by a hot glowing ignitor at
the beginning of each operation
cycle. The burner will continue to
operate until the thermostat is satisfied at which time all burner flame
is extinguished. During the off cycle
no gas is consumed. With the room
thermostat set below room temperature, and with the electrical power
and gas supply to the furnace on,
the normal sequence of operation
is as follows:
1. When the room temperature
falls below the setting of the
room thermostat, the thermostat energizes the furnace control board.
Unitary Products Group
035-16329-002 Rev. B (0304)
2. When the furnace control
board is activated, the combustion air blower is turned on.
3. As the combustion air blower
increases in speed, the contacts of the pressure switch will
close and complete the electrical circuit to the ignition circuit.
4. During the next 40 to 50 seconds, the combustion air
blower will bring fresh air into
the heat exchanger and the
ignitor will begin to glow. At the
end of this period, the gas
valve will open and the burner
will light.
5. After the burner lights, a separate sensor acts as a flame
probe to check for the presence of flame. As long as flame
is present, the system will
monitor it and hold the gas
valve open.
6. If the burner fails to light within
6-8 seconds after the gas valve
opens, the gas valve will close
and the ignitor will be turned
off. After a short pause, the
system will recycle and try
again for ignition. If the burner
fails to light after three tries, the
ignition system will lock out.
The system will remain in lockout mode for a period of one
hour, then the furnace will try
for ignition again.
Unitary Products Group
7. The lapsed time from the
moment the room thermostat
closes to when the burner
lights may be 45-60 seconds.
This delay is caused by:
a. The time required for the
ignitor to heat up and
b. The time required for fresh
air to be brought into the
heat exchanger.
8. Approximately 60-90 seconds
after the burner lights, furnace
air circulation blower will run.
9. When room thermostat is satisfied, the circuit to the furnace
control board is opened. The
circuit to the combustion air
blower and the gas valve is
opened and the burner is extinguished. Then the furnace control board will keep the
circulating blower running for a
fixed period of time to allow
additional heat to be drawn
from the heat exchanger.
DIAGNOSTIC LIGHT
If furnace does not maintain home
temperature as set, check the light
indicator, visible through a small
window in the right side of the furnace control box.
The electronic furnace control is
equipped with a diagnostic light
which flashes when there is a service problem. The diagnostic codes
are:
Steady on: Normal operation.
ONE flash: Ignition failure.
TWO flashes: Pressure switch
failed closed.
THREE flashes: Pressure switch
failed open.
FOUR flashes: Limit switch open.
FIVE flashes: Gas valve energized
with no call for heat
SIX flashes or
rapid flash: Reversed polarity
If a problem is indicated, contact
your authorized service person.
THE FURNACE CONTROLS
AND THEIR FUNCTION
1. System Switch - This system
switch turns “ON” or “OFF” the
120 volt electrical circuit that
powers the furnace controls
and the blower motor. The system switch must be turned
“ON” for the furnace to operate. Turn the switch to “OFF”
when cleaning the blower, etc.
2. Limit Control - This furnace is
protected by two (2) high temperature limit switches. The
lower limit switch is an automatic reset type.
3. Gas Valve - The gas valve for
the gas furnaces are a 100%
shut-off type and will fail safe if
for some reason the gas is
turned off.

GENERAL
INFORMATION FOR
ALL MODELS
For Heating with Air Conditioning Applications - Set heat/cool
switch to “HEAT” position and set
fan switch to “AUTO” position.
GAS SHUTOFF
Should
overheating
occur, or the gas supply
fail to shut off, shut off
the manual gas valve to
the furnace and allow
blower to run until furnace cools down and
blower shuts off before
shutting off the electrical
supply.
The furnace gas valve is equipped
with a manual gas shutoff. To turn
off gas to the furnace, move the
lever on the gas valve to the “OFF”
position.
The furnace installation should also
have a manual shutoff valve in the
gas piping to the furnace, similar to
what is shown in Figure 3. To turn
off the gas to the furnace, use a
wrench and turn the knob or lever
so that it is pointing 90 degrees
from the gas pipe, as shown in Figure 3.

For energy conservation and economy it is recommended that the
thermostat be set at 68º for heating
and 80º for cooling.
OBSERVING BURNER
OPERATION
1. Observe burner to make sure it
ignites. Observe color of flame.
On natural gas the flame will
burn blue with appreciably yellow tips. On Propane gas a yellow flame may be expected. If
flame is not the proper color
call a qualified serviceman for
service.
2. Let furnace heat until blower
cycles on.
3. Turn thermostat down.
4. Observe burner to make sure it
shuts off.
5. Let the furnace cool and
blower cycle off.
If any abnormalities are observed
when checking for correct operation, such as burner failing to ignite
or to turn off, sooty flame, etc., call
your nearest authorized service
technician as shown in the Service
Center List included in the home
owner envelope.
IF FURNACE FAILS TO
OPERATE PROPERLY
1. Check setting of thermostat and position of heat/cool switch
if air conditioning is installed. If
a set-back type thermostat is
employed be sure that the thermostat is in the correct operating mode.
2. Check to see that electrical
power is “ON”.
3. Check to see that the lever or
switch on the gas control valve
is in the full “ON” position.
4. Make sure filters are clean,
return grilles are not
obstructed, and supply registers are open.
5. Be sure that furnace flue piping
is open and unobstructed.
If the cause for the failure to
operate is not obvious, do not
attempt to service the furnace
yourself. Call a qualified service
agency or your gas supplier.
PERIODIC INSPECTION
AND MAINTENANCE BY
HOMEOWNER
It is recommended that the homeowner or user make an inspection
of the furnace at least every 90
days, or more often if desired. It is
also recommended that a qualified
service agency inspect the furnace
before each operating season the
furnace is used, both heating and
air conditioning, and at any time
that there is an indication of malfunction. The owner/user should
not attempt to disassemble the furnace unless experienced and qualified to do so.
FOR SAFETY - Turn off
electrical power to furnace before performing
service such as cleaning filters.
Filters
It is very important that filters in
your furnace or air conditioning
system be replaced frequently.
Clean filters not only provide added
comfort and a more healthful environment, but also allow the system
to operate more efficiently. Check
filters every two or three weeks.
Unitary Products Group
035-16329-002 Rev. B (0304)
Motor Lubrication
While you are away
The circulating air blower motor
and combustion air blower are permanently lubricated and do not
require periodic lubrication.
Your furnace is equipped with a
safety device which will shut off the
supply of gas to the burner in case
of malfunction. For this reason it is
never practical to assume that the
furnace will operate unattended for
a long period of time, especially if
there is a possibility of damage to
your property because of freezing.
So, if you plan to be away from
home, arrange for someone to
check your house every day.
Heat Exchanger Cleaning
Under normal conditions, the heat
exchanger should not require periodic cleaning. However, should
cleaning of the interior of the heat
exchanger become necessary,
access to the interior of the heat
exchanger may be gained by
removing the burner. Do not
attempt to disassemble any part of
the heat exchanger for cleaning.
Do not use any chemical for cleaning the heat exchanger. Such use
may cause a fire or explosion or
may result in corrosion of the
heat exchanger.
IMPORTANT - This furnace
must be serviced only by qualified
individuals specially trained in servicing of this type of equipment.
Installation and service personnel
are required to be licensed in some
areas. Persons not qualified should
not attempt to service this furnace.
Return Air
On some closet installations, the
return air opening to the furnace
may be on the floor, and/or on the
door and/or on the side wall of the
closet. The upper grille on the front
of the furnace admits return air to
the blower. Return air must be provided back to the circulating blower
in order to provide air distribution.
IMPORTANT - Do not obstruct
these openings including the grille
on the furnace. To do so will cause
the furnace to activate the high limit
and shut down or it may cause
asphyxiation.
Unitary Products Group
When You Call For Service
Assistance
Very often time can be saved if you
will give the service agency the
MODEL and SERIAL NUMBER of
your furnace. This will enable him
to determine the specific components used, and perhaps to better
identify the possible problem and
be better prepared if a service call
is required.

SEASONAL SERVICE
INFORMATION
COMPANY:__________________
During extreme cold weather, ice
may form on the furnace roof jack
crown. Small amounts of ice forming on the roof jack will present no
problem to proper furnace operation. However, excessive ice formation
could
restrict
the
combustion air supply to the burner
causing inefficient burner operation.
TELPHONE:_________________
When the temperature is very cold,
near zero or below, it is recommended that the roof jack be
inspected every day or more frequently if required. If ice has
started to collect on the roof jack
crown, it should be carefully broken
off.
Your Service Technician
Your furnace's best friend is your
qualified service technician. If the
unit gives any indication of
improper operation, call your service technician. If the service technician is allowed to perform the
normal routine care of your furnace, he can many times detect
potential difficulties and make corrections before trouble develops.
Preventative maintenance of this
type will allow you to operate the
unit with a minimum of concern,
and at the same time will pay for
itself in added years of comfort.
ADDRESS: __________________
All appliances need maintenance
by serviceman at the beginning of
each heating season. Call your
nearest authorized service technician to:
1. Replace filters. Clean all lint
and dust from around furnace.
2. Remove fan and clean all dust
and lint from unit with stiff bristle brush.
3. Inspect combustion chamber,
the transition into the blower
compartment, flue collar, and
roof jack.
4. Check the gas valve and line
connections for leaks.
5. Make any adjustments necessary for good operation.
NOTE: The coil panel provides a
good removable access for
inspecting inside the furnace casing. Smoke or
reflected light inside the
casing indicates the presence of leaks in the heat
exchanger.

IMPORTANT
As an owner of a new furnace you need to know the following information:
If your home is located at an elevation above 2,000 feet, the burner orifice in your furnace will need to be derated. Please contact the nearest authorized Service Center to have this procedure performed properly.
Your dealer or gas company may have already applied the proper deration for your unit. If so, they should be
able to advise you as such. If not, you need to have the deration made to insure continued use of your furnace.
Not having the unit derated properly will eventually render the furnace inoperable.
Deration of the orifice for furnaces installed in homes at elevations above 2,000 feet is not covered by the warranty. This procedure is considered a part of the installation process and is required to make the furnace operate
properly.
These furnaces are shipped from the factory with a natural gas orifice. If you will be operating this furnace on LP
(liquid propane gas), it will also be necessary to have the furnace converted. The correct LP orifice is supplied
with the furnace to allow operation at elevations below 2,000 feet. If the furnace will be operating on LP gas at
elevations above 2,000 feet, the orifice supplied will be too large to allow proper operation. You should contact
your LP supplier for assistance in getting the derated orifice installed.
We hope you follow these instructions and enjoy many years of trouble free service. If you have any questions,
please feel free to contact the technical assistance hot line at 1-800-231-4822.

ROOF JACK
NEW HOME INSTALLATION
If this furnace is installed on a new home do the following:
1.
Inspect the furnace top collars for signs of insulation or
ceiling debris which might have fallen in during cutting of
the ceiling and roof holes. Remove all debris before continuing.
2.
Only use the appropriate roof jack. See Figures 6
& 7 for correct application.
After unpacking the roof jack, check the rain caps. Insure
they are not damaged, tilted or crooked. Do not twist,
crush or sit on the roof caps during installation. Damaged
roof caps will cause improper furnace operation. The furnace will not heat properly and could result in explosion.
3.
Do not exceed the maximum height as determined from Figures 6 & 7. Installer should allow
an additional 1-1/2" travel before the flue pipe
assembly is fully extended against the built-in
stop. This provides an additional safeguard
against the flue assembly being pulled from the
roof jack during transportation or other stress
conditions.
Before inserting the vent pipe into the furnace top,
inspect the furnace flue and combustion air opening for
debris or insulation which have fallen in during pre-installation steps. Do not proceed unless all debris have been
cleaned out or removed.
4.
After installing roof jack on furnace top collar, check to
make sure there is no gap in back or side between the
pipe collar and the furnace casing top. If necessary to
prevent excessive air leakage, the installer should seal
joints in the combustion air tube with aluminum type or
other suitable sealant.
Failure to follow all venting instructions can result
in fire, asphyxiation, or explosion.
EXISTING FURNACE REPLACEMENT
If this furnace replaces an existing furnace, do the following:
INSTALLATION IN SNOW REGIONS
1.
If a 2nd roof, roof cap or addition has been made to the
existing roof of the home, remove the old roof jack completely! To avoid the possibility of an improperly installed
pipe or gaps in the old roof jack, INSTALL A NEW ROOF
JACK. Your ceiling and roof height will determine the correct roof jack to use. Refer to the vent selection table, of
the furnace installation instructions.
When the combustion air pipe inlet is covered or blocked with
snow, the furnace will not operate properly due to the
depleted combustion air supply.
After unpacking the roof jack, check the rain caps. Insure
they are not damaged, tilted or crooked. Do not twist,
crush or sit on the roof caps during installation. Damaged
roof caps will cause improper furnace operation. The furnace will not heat properly and could result in explosion.
LOCATING AND CUTTING ROOF JACK OPENING
2.
3.
Before inserting the roof jack into the furnace top,
inspect the furnace flue and combustion air opening for
debris or insulation which might have fallen in during preinstallation steps. Do not proceed unless all debris has
been cleaned out or removed.
4.
After installing roof jack on furnace top collar, check to
make sure there is no gap in back or side between the
pipe collar and the furnace casing top.
5.
Use only the pipes provided with the roof jack assembly.
Do not add to or adapt other sheet metal pipes. Do not
cut, insert or add other pipes to this assembly.
6.
6
In no case should there be a gap between sections of
the flue pipe or the combustion air pipe. If necessary to
prevent excessive air leakage, the installer should seal
joints in the combustion air tube with aluminum type or
other suitable sealant.
Therefore, if the furnace will be located in regions where
snow accumulation on the roof exceeds 7" or in H.U.D. Snow
Load Zones, a roof jack extension (Part No. 7680B6541) is
recommended.
To facilitate the proper installation of the roof jack, it is very
important that the roof jack opening in the ceiling and roof be
on the same vertical center line as the furnace flue collar. See
Figure 9.
Mark this location on ceiling and scribe a circle with a 5"
radius (10" diameter) around this mark. Cut opening for roof
jack through ceiling and roof. (If furnace was installed during
construction, cover furnace and flue opening to prevent
debris from entering flue when hole is cut for roof jack.)
INSTALLING ROOF JACK IN ROOF
(See Figure 6 & 7 for Dimensional requirements.)
Insert roof jack into opening in the roof.
The roof jack should be secured to the furnace before roof
flange (flashing) is secured to the roof. This will insure a better alignment of the flue pipe and furnace flue collar. Caulk
around and under roof flange to provide a water tight seal,
before securing roof jack flashing to roof.

GAS PIPING
INSTALLATION AND CHECKING OF GAS LINE
Gas Supply piping must be sized in accordance with the recommendations contained in National Fuel Gas Code (ANSIZ223.1, NFPA-54) unless local codes or regulations state otherwise.
Materials used and pipe sizing for U.S. manufactured homes
must comply with requirements contained in Manufactured
Homes A119.1, Recreational Vehicles A119.2 and H.U.D.
Title 24, Section 3280.705 and any local or state codes.
NOTE: The gas line inlet on the gas valve is 1/2-14 N.P.T.
The gas line may be installed through the furnace floor or furnace side to the gas valve.
To install gas line and to connect it to the gas
valve, care must be taken to hold gas valve firmly
to prevent misalignment of the burner orifice, or
to damage gas valve which could result in
improper heating, explosion, fire or asphyxiation.
DO NOT USE EXCESSIVE PIPE SEALANT ON
PIPE JOINTS. Pipe sealant, metal chips or other
foreign material that could be deposited in the
inlet of the gas valve, when gas pipe is installed
or carried through the gas piping into the gas
valve inlet after installation, may cause the gas
valve to malfunction and could result in possible
improper heating, explosion, fire or asphyxiation.
Also, pipe sealant must be resistant to Propane
gas.
For natural gas operation, the furnace is designed for 7" W.C.
inlet gas pressure. Pressure to main burner is then reduced
to 3 1/2" W.C.
For Propane gas operation, the furnace is designed for 11"
W.C. inlet gas pressure. Pressure to main burner is then
reduced to 10" W.C.
IMPORTANT - When converting gas valve from or to Propane gas, it will be necessary to change main burner orifice
to prevent an underfired or overfired condition. See label
inside lower furnace door for complete instructions.
Pilot Adjustment
On models equipped with standing pilot ignition, the pilot
should be adjusted so that the flame is approximately 1” in
height (500 BTU / hr.). This will allow proper burner ignition
without excessive fuel usage. The pilot adjustment screw is
located on the top of the gas valve.
Observing Burner Operation
1.
Observe burner to make sure it ignites. Observe color of
flame. On natural gas the flame will burn blue with appreciably yellow tips. On Propane gas a yellow flame may
be expected. If flame is not the proper color call a qualified service technician for service.
2.
Let furnace heat until blower cycles on.
3.
Turn thermostat down.
4.
Observe burner to make sure it shuts off.
5.
Let the furnace cool and blower cycle off.
Should overheating occur, or the gas supply fail
to shut off, shut off the manual gas valve to the
furnace and allow burner to run until furnace
cools down and blower shuts off before shutting
off the electrical supply.
Where regulations require, a main shut-off valve
shall be installed externally of furnace casing.
After piping has been installed, turn gas on and
check all connections with a leak detector or
soap solution.
Never use open flame to test for gas leaks as
fire or explosion could occur.
Do not test the fuel system at more than 14" W.C.
after furnace has been connected to fuel line.
Such testing could void the warranty. Any test run
above 14" W.C. may damage furnace control
valve which could cause an explosion, fire or
asphyxiation.
If the gas input to the furnace is too great
because of excessive gas pressure, wrong size
orifice, high altitude, etc., the burner flame will be
sooty and may produce carbon monoxide, which
could result in unsafe operation, explosion, and/
or fire or asphyxiation.
A dirt leg may be required by some local codes to trap moisture and contaminations.
Unitary Products Group
If any abnormalities are observed when checking for correct
operation, such as burner failing to ignite or to turn off, sooty
flame, etc., call your nearest authorized service technician as
shown in the Service Center List included in the home owner
envelope with the furnace.
If Furnace Fails to Operate Properly
1.
Check setting of thermostat - and position of HEAT/
COOL switch if air conditioning is installed. If a set-back
type thermostat is employed be sure that the thermostat
is in the correct operating mode.
2.
Check to see that electrical power is ON.
3.
Check to see that the knob or switch on the gas control
valve is in the full ON position.
4.
Make sure filters are clean, return grilles are not
obstructed, and supply registers are open.
5.
Be sure that furnace flue piping is open and unobstructed.
If the cause for the failure to operate is not obvious, do not
attempt to service the furnace yourself. Call a qualified service agency or your gas supplier.

FINAL PROCEDURE
FURNACE AND AIR CONDITIONER
INSTALLATIONS
INSTALL FURNACE DOORS
Install the lower door first by sliding the bottom of the door
down until the tabs on the casing base engage the slots in the
bottom door end cap. Then push the top of the lower door in
until the door clips snap into place. Install the upper door in a
similar manner, first engaging the slots in the top of the upper
door on the tabs on the casing top. Then snap the bottom of
the upper door into place against the casing.
FINISH AND TRIM
Alcove and Closet Installations may now be finished and
trimmed as necessary.
AUTOMATIC
DAMPER
If an air conditioner is installed which does not use the blower
for air distribution and operates completely independent of
the furnace, the thermostat system must have an interlock to
prevent the furnace and air conditioner from operating at the
same time. This interlock system usually contains a heat-cool
switch which must be turned to either HEAT or COOL to activate either heating or cooling operation, or a positive OFF
switch on the cooling thermostat.
When used in connection with a cooling unit the furnace shall
be installed parallel with or on the upstream side of the cooling unit to avoid condensation in the heat exchanger.
For installations with a parallel flow arrangement, the furnace
must be equipped with a damper to prevent cold air from
being discharged up around the heat exchanger. Cold air
causes condensation inside the exchanger and can cause it
to rust out which can allow products of combustion to be circulated into the living area by the furnace blower resulting in
possible asphyxiation. An air flow activated automatic
damper, P/N 7900-6771, is available from furnace manufacturer. See Figure 24.
NOTE: See label on coil panel for conversion and lighting
instructions. Obtain a temperature rise within the ranges
specified on the name plate.
