PROPANE GAS IS HEAVIER THAN AIR AND MAY
COLLECT IN ANY LOW AREAS OR CONFINED
SPACES. IN ADDITION, ODORANT FADE MAY MAKE
THE GAS UNDETECTABLE EXCEPT WITH A WARNING
DEVICE. IF THE GAS FURNACE IS INSTALLED IN A
BASEMENT, AN EXCAVATED AREA OR A CONFINED
SPACE, IT IS STRONGLY RECOMMENDED TO
CONTACT A GAS SUPPLIER TO INSTALL A GAS
DETECTING WARNING DEVICE IN CASE OF A GAS
LEAK. THE MANUFACTURER OF YOUR FURNACE
DOES NOT TEST ANY DETECTORS AND MAKES NO
REPRESENTATIONS REGARDING ANY BRAND OR
TYPE OF DETECTOR.
Never operate your unit for either heating or cooling
with filters removed.
Safety Hazard

ELECTRIC SHOCK HAZARD
THESE SERVICING INSTRUCTIONS ARE FOR USE
BY QUALIFIED PERSONNEL ONLY. TO REDUCE THE
RISK OF ELECTRIC SHOCK, DO NOT PERFORM ANY
SERVICING OTHER THAN THAT CONTAINED IN THESE
OPERATING INSTRUCTIONS UNLESS YOU ARE
QUALIFIED TO DO SO.
FAILURE TO FOLLOW THIS WARNING COULD RESULT
IN PROPERTY DAMAGE, PERSONAL INJURY OR
DEATH.
CARBON MONOXIDE HAZARD
FOR PROPER AND SAFE OPERATION OF THE FURNACE, AIR FOR COMBUSTION AND VENTILATION
MUST BE PROVIDED. DO NOT BLOCK OR OBSTRUCT
AIR OPENINGS ON THE FURNACE, AIR OPENINGS TO
THE AREA IN WHICH THE FURNACE IS INSTALLED, OR
THE SPACE AROUND THE FURNACE.
FAILURE TO FOLLOW THIS WARNING COULD RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR
DEATH.
If the furnace is shut down during the cold weather
months, provisions must be taken to prevent freeze-up
of all water pipes and water receptacles.
Do NOT touch igniter. It is extremely hot.
The furnace area must be kept clear and free of combustible materials, gasoline, and other flammable
vapors and liquids.
IMPORTANT FACTS
The flow of combustion and ventilating air must not
be obstructed from reaching the furnace. Air openings
provided in the casing of the furnace must be kept free
of obstructions which would restrict airflow, thereby affecting efficiency and safe operation of your furnace.
Also, air openings provided to the area in which the furnace is installed and the space around the furnace shall
not be blocked or obstructed. Keep this in mind should
you choose to remodel the area which contains your furnace. If additional insulation is added after the furnace
is installed, the area around the furnace must be inspected to ensure it is free and clear of insulation. If this
furnace is installed in an attic or other insulated space
it must be kept free and clear of all insulating materials
as some insulating materials are combustible.
Furnaces must have air for proper performance. There
must be a free flow of fresh air sufficient for efficient
combustion and safe ventilation of your furnace.
Never store gasoline, combustible materials, or
other flammable liquids or vapors near your furnace.
Carbon monoxide, fire or smoke can cause serious bodily injury, death, and/or property damage.
A variety of potential sources of carbon monoxide can
be found in a building or dwelling such as gas-fired
clothes dryers, gas cooking stoves, water heaters, furnaces and fireplaces. The U.S. Consumer Product Safety Commission recommends that users of gas-burning
appliances install carbon monoxide detectors as well as
fire and smoke detectors, listed by a nationally recognized agency (e.g. Underwriters Laboratories or International Approval Services), to help alert dwelling occupants of the presence of fire, smoke or unsafe levels
of carbon monoxide.
Insulating materials may be combustible. The furnace
must be kept free and clear from insulating material.
Examine the area around the furnace for insulation
after installation or when insulation is added.
The combustion air for your furnace must be fresh uncontaminated air. Paints, varnishes, laundry bleaches,
detergents, many household cleaners, water softening
salts, adhesives, and all such products release fumes
containing compounds which could lead to early heat
exchanger and vent system deterioration. Do NOT
store these types of products near your furnace.
For horizontally vented furnaces, the vent and inlet
terminals must be located at least 12 inches minimum
(18 inches in Canada) above normally expected snow
accumulation level.
32-5035-13 3
NOTE: The manufacturer of your furnace does not test
any detectors and makes no representations regarding
any brand or type of detector.
Installing and servicing heating equipment can be
hazardous due to gas and electrical components. Only
trained and qualified personnel should install, repair
or service heating equipment.
Untrained personnel can perform basic maintenance
functions such as cleaning and replacing filters. All
other operations must be performed by trained service
personnel.
Parts and controls of this furnace are unique. Should
service or modification be required, be sure your servicer uses only factory authorized parts, kits, or accessories for this furnace.
If you experience a problem with the operation of your
furnace, check the “Problem Solver” section of this
manual before you call for a possibly unneeded service
call.

To Start the Furnace
Lighting instructions.
Your furnace does not use a continuously burning pilot
flame. Therefore, manually lighting your furnace is not
required. Your furnace is equipped with an automatic
ignition system. It uses a hot surface ignition device
that automatically lights the burners each time the
comfort control signals the furnace to start.
BURN HAZARD
DO NOT ATTEMPT TO MANUALLY LIGHT THE FURNACE. FAILURE TO FOLLOW THIS WARNING COULD
RESULT IN PROPERTY DAMAGE, PERSONAL INJURY
OR DEATH.
If the furnace is shut down during the cold weather
months, provisions must be taken to prevent freeze-up
of all water pipes and water receptacles.
1. Please read all safety information in this book before operating furnace.
2. Set comfort control to lowest setting. Turn off all
electric power to furnace.
3. Remove the furnace front panel to gain access to
the main gas valve.
4. Turn external main gas shutoff valve or the toggle switch located on the main gas valve inside
the unit to the “OFF” position (see illustration on
this page). If an external main gas shutoff valve
is used, turn to “OFF” position (see illustration
on next page). Allow 5 minutes for any gas within
the unit to escape. LP gas being heavier than air
may require forced ventilation. If you smell gas
STOP! Follow the “What To Do If You Smell
Gas” instructions on the front cover of this
book. If you don’t smell gas, go to next step.
5. Turn the external main gas shutoff valve and the
toggle switch located on the main gas valve inside
the unit to the “ON” position (see illustration on
this page).
6. Replace the furnace front access panel.
7. Turn on main electrical supply and set comfort
control to desired setting. Combustion blower will
start and ignition device will start to heat up. After
approximately 15 seconds main gas valve will open
and burners will ignite.
8. When the comfort control is satisfied, main burners will extinguish.
9. If main burners fail to ignite turn off the main
electrical supply power or lower the comfort control setting and wait 5 minutes.
10. Raise the comfort control setting and restore electrical supply power. Repeat steps 6 through 8.
11. If furnace still will not light, turn “OFF” all gas
and electricity to unit and call servicer or gas supplier.
For complete shutdown.
Turn the external main gas shutoff valve and the toggle switch on the main gas valve inside the unit to the
“OFF” position. Disconnect electrical supply to unit.
Whenever your house is to be vacant, arrange to have
someone inspect your house for proper temperature. If
precautions are not taken, damage could result, such
as frozen water pipes.
Flame Roll-out Device.
All models are equipped with a manual resetting rollout switch located near the burners. In case of flame
roll-out, the switch trips automatically shutting off
all flow of gas. The switch must be manually reset by
pressing the red reset button on the top of the switch.
On/Off Switch
Your furnace will have a switch to turn the gas ON or OFF.
