WARNING  
CARBON MONOXIDE POISONING HAZARD  
Failure to follow this warning could result in personal  
injury and/or death.  
To minimize the possibility of serious personal injury, fire, furnace  
damage, or improper operation; carefully follow these safety  
rules:  
Carbon Monoxide is invisible, odorless, and toxic!  
A
carbon monoxide alarm is recommended in your home,  
even if you do not own a gas appliance. Locate the carbon  
monoxide alarm in the living area of your home and away  
from gas appliances and doorways to attached garages.  
Follow the alarm manufacturer’s instruction included with  
the alarm.  
S Your gas furnace uses air from outside the home for combustion  
and vents flue gas to the outdoors. It is not to be installed using  
indoor air for combustion. The vent pipe must terminate outside  
the structure and must not be obstructed in any way. The  
air--intake pipe must terminate outside the structure or in a well  
ventilated area that is isolated from the living space and the  
garage (e.g. well ventilated attic or crawlspace). Do not block or  
obstruct air openings on furnace or spaces around furnace.  
S Keep the area around your furnace clear and free of combustible  
materials, gasoline, and other flammable liquids and vapors.  
Do not use this furnace if any part has been under water. A  
flood--damaged furnace is extremely dangerous. Attempts to  
use the furnace can result in fire or explosion. A qualified  
service agency should be contacted to inspect the furnace  
and to replace all gas controls, control system parts,  
electrical parts that have been wet or the furnace if deemed  
necessary.

form this test in the kitchen, cooking vapors may produce  
inaccurate results.)  
A good relative humidity is one just high enough to barely start  
condensation along the lower edges or lower corners of the  
windows, when it is cold outside. More than that can be damaging.  
Thermostat  
There are many types and styles of thermostats. Most thermostats  
control both heating and cooling functions and have a Fan Switch  
with AUTO and ON settings. On AUTO, the Circulating Air  
Blower will cycle on/off with the furnace on the heating speed  
unless a call for cooling is initiated. Blower speed will correspond  
to the mode of operation of the furnace. If the Fan Switch is  
positioned to ON the blower will run continuously.  
If the humidity is too high, try these suggestions to lower the  
humidity:  
1. Reduce setting or discontinue use of humidifier.  
In addition some thermostats are programmable with multiple set  
backs. The set backs can be pre--programmed to lower or raise the  
temperature automatically.  
2. Use range and bathroom exhaust fans while cooking and  
bathing. Open a door or window for a few minutes to bring  
in cool drier air.  
Be sure to become familiar with your thermostat.  
3. Cook with pans covered.  
Rating Plate  
4. Take shorter baths or showers with cooler water.  
5. Install a fresh air intake duct. Cold, dry air brought in from  
outside to the furnace area lowers the indoor humidity level.  
6. Have appliances checked. A malfunctioning appliance can  
contribute water vapor to the structure.  
7. If the problem continues, consult a heating contractor about  
adding a heat recovery ventilator or air--to--air heat ex-  
changer.  
The rating plate contains important information for the service  
technician and lists the complete model, manufacturing and serial  
numbers. You should always provide all these numbers when  
requesting parts or if you need service. See Fig. 2 for rating plate  
location.  
Door Interlock Switch  
All the electrical power for the furnace goes through the door  
interlock switch. The interlock switch interrupts electrical power to  
the furnace when the blower door is removed. The furnace will not  
operate until the blower door is reinstalled.  
About Your Furnace  
Fig. 2 shows the location of the components in the furnace.  
Circulating Air Blower  
Furnace Control  
The furnace control provides power to the circulating air blower to  
keep it on until the furnace cools down.  
The fan off--delay setting can be adjusted if the fan remains on long  
enough that cool drafts are felt in the room after the furnace shuts  
off.  
The blower circulates room air through the furnace, air ducts, and  
into the rooms of the structure. The blower can be set at the  
thermostat for automatic or manual operation. In manual mode the  
blower operates continuously. In automatic, the blower does not  
come on until a preset time after the gas valve is energized. When  
the structure reaches the temperature set on the thermostat, the  
furnace will shut off. The blower will continue to run until the  
furnace cools down.

The off--delay is set by moving a jumper on the control. The  
Wiring Diagram located on the inside of the blower door shows the  
various delay combinations. Refer to Fig. 2 for location of the  
control.  
If you are unsure how to set the Off--delay Control, contact a  
Qualified Service Agency.  
Should overheating occur or the gas control valve fail to shut  
off, shut off the manual equipment shutoff valve to the furnace  
before shutting off the electrical supply.  
Extended Shutdown  
1. Set thermostat to lowest temperature setting or set thermo-  
stat System Select Switch to OFF, if so equipped.  
Set the room thermostat slightly above room temperature. This will  
automatically signal the furnace to start. The inducer motor will  
start, and the hot surface igniter will have an orange glow. After  
about 32 seconds (from the call for heat at the thermostat), the gas  
valve permits gas to flow to the main burners where it is ignited.  
When the flame is firmly established, the igniter shuts off. Hot  
flames begin to warm the furnace’s heat exchanger. After a time  
delay of 30 seconds, the furnace blower is switched on.  
NOTE: If the main burners fail to ignite, the furnace control  
system will go through 3 more ignition cycles. Then, if burners fail  
to ignite, the system will lockout. If lockout occurs, or the blower  
doesn’t come on, shut down your furnace and call a Qualified  
Service Agency for service.  
2. Turn Manual Equipment Shutoff Valve for furnace to OFF  
position (at right angle or 90_ to gas line).  
3. Remove the burner compartment door by removing the two  
(2) screws securing the door in front and lifting the door up  
and outwards. Removing the door will expose the gas con-  
trol valve knob.  
4. Turn OFF electric power to the furnace at the disconnect  
switch or circuit breaker. (May be left ON for set--back type  
thermostat with batteries, provided thermostat has system  
select switch placed in the OFF position.)  
5. Turn the the gas control valve to the OFF position. See Fig.  
3.  
6. Reinstall all doors.  
Pressure Switch  
The furnace is equipped with one or more pressure switches to shut  
down the furnace under various flue conditions. The switches are  
connected to the furnace by factory supplied tubing.

WARNING  
Operating Your Furnace  
Keep the blower access door and all access panels in place except  
for inspection or maintenance.  
Before starting your furnace be sure you read and understand all of  
the procedures in this manual. Check to make sure the furnace filter  
is clean and correctly installed.  
FIRE OR EXPLOSION HAZARD  
Failure to follow this warning could result in property damage,  
personal injury or death.  
Propane gas is heavier than air. Leaking gas could settle in low  
areas such as crawl space. If you suspect the presence of gas,  
follow the instructions on the cover of this manual.  
!
WARNING  
If your propane gas furnace is installed in an excavated or low  
lying area, we recommend that you contact your propane gas  
supplier about installing a warning device that would alert you of a  
gas leak.  
CARBON MONOXIDE POISONING HAZARD  
Failure to follow this warning could result in personal injury  
or death.  
Provisions for combustion and ventilation air must be  
provided for in accordance with installation instructions  
supplied with furnace.

CAUTION  
PROPERTY DAMAGE HAZARD  
Starting The Furnace  
See Fig. 4 for an illustration of the gas control valve.  
Failure to follow this caution may result in property damage  
Furnace may shut down. Do not leave your home unattended  
for long periods during freezing weather without turning off  
water supply and draining water pipes or otherwise protecting  
against the risk of frozen pipes.  
1. Turn the thermostat to its lowest temperature setting or to  
OFF if equipped with a System Select Switch.  
2. Turn OFF all electric power to the furnace at the disconnect  
switch or circuit breaker.  
3. Remove the burner compartment door by removing the  
two(2) screws securing the door in front and lifting the door  
up and outwards. Removing the door will expose the gas  
control valve knob.  
Your furnace is designed solely to provide a safe and comfortable  
living environment. The furnace is NOT designed to ensure that  
water pipes will not freeze. It is equipped with several safety  
devices that are designed to turn the furnace off and prevent it from  
restarting in the event of various potentially unsafe conditions.  
4. Turn the gas control valve to the OFF position. See Fig. 3.  
5. Wait five (5) minutes to clear out any gas. If you then smell  
gas, STOP! Follow the safety information on the cover of  
this manual. If you do not smell gas, go to the next step.  
6. Turn the gas control valve to the ON position. See Fig. 3.  
7. Reinstall all doors.  
If your furnace remains off for an extended time, the pipes in your  
home could freeze and burst, resulting in water damage. If the  
structure will be unattended during cold weather, you should take  
these precautions.  
1. Turn off the water supply to the structure and drain the wa-  
ter lines if possible and add an antifreeze for potable water  
to drain traps and toilet tanks. Open faucets in appropriate  
areas.  
8. Turn ON all electrical power to the furnace.  
9. Set the thermostat to the desired temperature and the System  
Select Switch to HEAT.

Air Filters/Monthly  
Fig. 3 -- Gas Control Valve  
The air filter(s) should be inspected at least monthly and cleaned or  
replaced as required. There are many types of filters that are  
commonly used. Washable filters (constructed of aluminum mesh,  
foam, or reinforced fibers) may be cleaned by soaking in mild  
detergent and rinsing with water. The fiberglass disposable type  
should be REPLACED before it becomes clogged. Other filter  
types should be serviced in accordance with the manufacturer’s  
recommendations.  
2. Have someone check the structure frequently during cold  
weather to make sure it is warm enough to prevent pipes  
from freezing. Instruct them to call a qualified service  
agency to call to provide service, if required.  
-- o r --  
3. Install a reliable remote sensing device that will notify  
somebody of freezing conditions within the home.  
Remember that dirty filters are the most common cause of  
inadequate heating or cooling performance.  
Winter Shutdown (90+ Furnaces)  
If you go away during the winter months and do not leave the heat  
on in your home, the plastic transition box and the condensate trap  
on the furnace must be protected from freeze damage. (See Fig. 2)  
Replacement Filters  
If the filter is not located at or within the furnace, it should be  
located somewhere in the return--air duct system.  
1. Disconnect the 1/2” I.D. rubber hose from the vent drain fit-  
ting (or tee) that is located downstream of the combustion  
blower. Insert a funnel into the hose and pour four (4)  
ounces of sanitary type (RV) antifreeze into the condensate  
trap. Reconnect the 1/2” I.D. rubber hose to the stub on the  
vent drain fitting. Secure with the hose clamp.  
2. Disconnect the 5/8” I.D. rubber hose from the condensate  
trap. Insert a funnel into the hose and pour four (4) ounces  
of sanitary type (RV) antifreeze into the plastic transition  
box. Squeeze the hose together near the end and quickly re-  
connect the 5/8” I.D. rubber hose to the stub on the con-  
densate trap. Secure with the hose clamp.  
The recommended sizes and types of filters that may be used with  
your furnace are based on the furnace’s heating gas input rate (and  
cooling system capacity, if so equipped).  
Replacement filters should be of the same type and size as the  
original filters, to ensure adequate air flow and filtering. A  
disposable low velocity filter can be replaced with a washable high  
velocity type. Do not replace a high velocity filter with a  
disposable low velocity filter, except as permitted below.  
If a cleanable (high--velocity) filter(s) is to be replaced with a  
disposable (low--velocity) filter(s), the airflow area of the filter(s)  
must be doubled (i.e., a second filter of the same size must be  
installed so that only half of the air goes through each filter). A  
second return--air duct to the furnace may be required in which to  
install the second filter. Modification of a furnace installation shall  
comply with the local installation code and the furnace installation  
instructions, and shall be made only by a Qualified Service  
Agency.  
3. When you return home, your furnace will be ready to start,  
as it is not necessary to drain the antifreeze from the furnace.  
Furnace Maintenance  
Have your furnace inspected and serviced on an annual basis  
(before the heating season) by a qualified service agency.  
NOTE: Some filters are marked with an arrow to indicate the  
proper direction of air flow through the filter. The air flow  
direction will be towards the blower motor. Make sure filter is  
installed correctly.

FIRE OR EXPLOSION HAZARD  
Filter Replacement -- Upflow  
Failure to follow this warning could result in personal injury  
or death.  
The filter may be installed inside the bottom of the furnace blower  
compartment, or the filter(s) rack may be installed under the  
furnace or on either or both sides of the furnace. A plastic end  
cap(s) is inserted in the filter rack(s) after the filter(s) is installed.  
The end cap keeps air from escaping around the open end of the  
filter rack. See Fig. 4 and Fig. 5 for side and bottom locations.  
Rack end cap is similar for bottom mounted filter rack.  
Label all wires prior to disconnection when servicing controls.  
Verify proper operation after servicing. Only qualified service  
agencies should attempt electrical service.
