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.

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.

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.

User’s Information

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.

NOTE:
The manufacturer of your furnace does not test any detec­tors and makes no representations regarding any brand or
type of detector.

!

WARNING

▲

BODILY INJURY CAN RESULT FROM HIGH VOLTAGE
ELECTRICAL COMPONENTS, FAST MOVING FANS, AND
COMBUSTIBLE GAS. FOR PROTECTION FROM THESE
INHERENT HAZARDS DURING INSTALLATION AND
SERVICING, THE ELECTRICAL SUPPLY MUST BE DIS­CONNECTED AND THE MAIN GAS VALVE MUST BE
TURNED OFF.

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.

!

WARNING

▲

Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. Refer to
the installation instructions provided with the furnace and
this manual. For assistance or additional information con­sult a qualified installer, service agency or the gas supplier.

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 thermostat signals the furnace to
start.

!

WARNING

▲

Do not attempt to manually light the furnace.

1. Please read all safety information in this book before
operating furnace.

2. Set thermostat 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 gas cock knob clockwise or the toggle switch located
on the main gas valve inside the unit to “OFF” position
(see illustration on next page). If external gas cock 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 gas cock knob counterclockwise or the toggle switch
to “ON” marker (see illustration on next page).

6. Replace the furnace front access panel.

7. Turn on main electrical supply and set thermostat 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 thermostat is satisfied, main burners will
extinguish.

9. If main burners fail to ignite, lower thermostat setting or
disconnect electrical supply, wait 5 minutes, raise
thermostat setting above indicated temperature.

10. If furnace will not light, turn “OFF” all gas and electric­ity to unit and call servicer or gas supplier.

For complete shutdown.

Turn gas cock knob on main gas valve to “OFF” position.
Disconnect electrical supply to unit.

!

CAUTION

▲

If this is done during the cold weather months, provisions
must be taken to prevent freeze-up of all water pipes and
water receptacles.

Whenever your house is to be vacant, arrange to have
someone inspect your house for proper temperature. If your
furnace should fail to operate, damage could result, such as
frozen water pipes.

Flame Roll-out Device.

All models are equipped with a fusible link located near the
burners. In case of flame roll-out, the link will open (melt)
and cause the circuit to open which shuts off all flow of gas.

Proper Maintenance
Reduces Energy Use

A clean filter saves money.

When the furnace circulates and filters the air in your home,
dust and dirt particles build up on the filter. Excessive
accumulation can block the airflow, forcing the unit to work
harder to maintain desired temperatures.

And the harder your unit has to work, the more energy it
uses. So you pay more any time your system is running with
a dirty filter.

!

CAUTION

▲

Never operate your unit for either heating or cooling with
filters removed.

Help ensure top efficiency by cleaning the filter once a month.
If you have an upflow furnace, you can wash or change the
filter once a month. Clean it twice a month during seasons
when the unit runs more often.

Your furnace came from the factory with a cleanable filter.
You can clean the filter with a vacuum, OR you can wash it
with a household detergent. Good quality, high velocity
filters may be used for replacements in upflow furnaces.

Replacing your filter.

When replacing your furnace filters, use a high velocity type
filter. On upflow furnaces, standard size 1" thick high
velocity filters will fit into the patented filter rack which will
automatically adjust in width to fit. Filters are available
from your dealer.

How to remove your filter.

The upflow furnace blower door has a hinge at the bottom
which allows the door to tilt forward for filter servicing or
replacement without the door being removed. The furnace
filter in the bottom or side configuration can be removed by
simply turning the two latches on the blower door 1/4 turn
and tilting the door forward.

Airflow

With the new patented filter rack on the upflow models, all
cleaning or replacing of filters is quick and easy. Clean filters
guarantee optimum performance of your system.

3. IGNITER – This unit has a special hot surface direct
ignition device that automatically lights the burners.
Please note that it is very fragile and should be handled
with care.

!

CAUTION

▲

Do not touch igniter. It is extremely hot.

4. BURNER – Gas burners do not normally require
scheduled servicing, however, accumulation of foreign
material may cause a yellowing flame or delayed igni­tion. Either condition indicates that a service call is
required. For best operation, burners must be cleaned
annually using brushes and vacuum cleaner.

Turn off gas and electric power supply. To clean burners,
remove top burner bracket and lift burner from orifice.

NOTE:
Be careful not to break igniter when removing burners.

Clean burners with brush and/or vacuum cleaner.
Reassemble parts by reversal of the above procedure.

NOTE: On LP (propane) units, some light yellow tipping of
the outer mantle is normal. Inner mantle should be bright
blue.

Natural gas units should not have any yellow tipped flames.
This condition indicates that a service call is required. For
best operation, burners must be cleaned annually using
brushes and vacuum cleaner.

NOTE: On LP (propane) units, due to variations in BTU
content and altitude, servicing may be required at shorter
intervals.

5. HEAT EXCHANGER / FLUE PIPE – These items
must be inspected for signs of corrosion, and/or
deterioration at the beginning of each heating season
by a qualified service technician and cleaned annually
for best operation.

6. CIRCUIT PROTECTION – If blower or gas valve fail to
operate, the cause could be the circuit breaker or a loose
or blown fuse. Replace fuse or reset circuit breaker.

7. OPERATION – Your warm air furnace should not be
operated in a corrosive atmosphere. Paint solvents,
cleaning chemicals, spray propellants, and bleaches
should not be used in the vicinity of the furnace during
normal operation.

8. CONDENSATE DRAINS – If you have a cooling coil
installed with your furnace, condensate drains should be
checked and cleaned periodically to assure that conden­sate can drain freely from coil to drain. If condensate
cannot drain freely water damage could occur. Furnace
drain should also be checked & cleaned at the start of
each heating season.

9. AIR CIRCULATION – To ensure increased comfort, the
blower on this unit may be operated continuously for
both heating and cooling. This will result in constantly
filtered air and aid in maintaining more even tempera­tures by avoiding temperature stratification throughout
the conditioned area. To accomplish constant air
circulation, set your thermostat fan switch to “ON”.
