Filter maintenance reduces energy use.
How to remove your filter.
WARNING: Disconnect power to the
unit before removing the blower door. Failure to
follow this warning could result in property damage,
personal injury or death.
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
WARNING: Disconnect power to the
unit before removing the blower door. Failure to
follow this warning could result in property damage,
personal injury or death.
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.
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.
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.
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.
Blower Door Hinge and Bottom Filter Rack Installation
The blower door may be removed if necessary by tilting the
door outward 2 to 3 inches, then pulling up. The door will
slide out of the hinge for removal. For replacement, simply
insert the blower door bottom into the space between the
furnace base front and the hinge, then tilt inward and
latch.

The problem solver.
A furnace is not a household appliance. It is complex and
requires professional maintenance and repair.
That’s why attempts at “do-it-yourself” repairs on an inwarranty unit may void the remainder of your warranty.
Other than performing the simple maintenance recommended in this manual, you should not attempt to make
any adjustments to your furnace. Your dealer will be able
to take care of any questions or problems you may have. A
periodic inspection of your furnace should be made by a
qualified service agency at the start of each heating season.
Keep your furnace looking like new for years.
Clean the enamel finish of your furnace with ordinary soap
and water. For stubborn grease spots, use a household
detergent. Lacquer thinner or other synthetic solvents may
damage the finish.
Save time and money. Before calling for service, check the following:

Maintenance information.
Never stop the cooling system by shutting off the
main power.
If the main power to your air conditioner is ever disconnected for more than three hours, turn off the thermostat.
Then wait for at least three more hours after the power has
been restored before turning the thermostat back on.
Failure to follow this procedure could result in damage to
your air conditioning system.
1. GENERAL INSPECTION - Examine the furnace installation for the following items:
a. All flue product carrying areas external to the furnace (i.e. chimney, vent connector) are clear and free of
obstruction.
b. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corrosion.
c. The return air duct connection(s) is physically sound,
is sealed to the furnace and terminates outside the
space containing the furnace.
d. The physical support of the furnace should be sound
without sagging, cracks, gaps, etc., around the base so
as to provide a seal between the support and the base.
e. There are no obvious signs of deterioration of the
furnace.
WARNING:
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.
Do not touch igniter. It is extremely hot. Failure to
follow this warning could result in severe burns.
2. BLOWERS - The blower size and speed determine the
air volume delivered by the furnace. The blower motor
bearings are factory lubricated and under normal operating conditions usually do not require servicing. Annual
cleaning of the blower wheel and housing is recommended
for maximum air output, and this must be performed only
by a qualified servicer or service agency.
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.
Pub. No. 32-5034-02 Page 7
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. COOLING COIL CONDENSATE DRAIN - 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.
9. AIR CIRCULATION - To ensure increased comfort,
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".
WARNING: Disconnect power to the
unit before removing the blower door. Failure to
follow this warning could result in property damage,
personal injury or death.

How to remove your filter.
WARNING: Disconnect power to the
unit before removing the blower door. Failure to
follow this warning could result in property damage,
personal injury or death.
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
WARNING: Disconnect power to the
unit before removing the blower door. Failure to
follow this warning could result in property damage,
personal injury or death.
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.
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.
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.
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.
Blower Door Hinge and Bottom Filter Rack Installation
The blower door may be removed if necessary by tilting the
door outward 2 to 3 inches, then pulling up. The door will
slide out of the hinge for removal. For replacement, simply
insert the blower door bottom into the space between the
furnace base front and the hinge, then tilt inward and

The problem solver.
A furnace is not a household appliance. It is complex and
requires professional maintenance and repair.
That’s why attempts at “do-it-yourself” repairs on an inwarranty unit may void the remainder of your warranty.
Other than performing the simple maintenance recommended in this manual, you should not attempt to make
any adjustments to your furnace. Your dealer will be able
to take care of any questions or problems you may have. A
periodic inspection of your furnace should be made by a
qualified service agency at the start of each heating season.
Keep your furnace looking like new for years.
Clean the enamel finish of your furnace with ordinary soap
and water. For stubborn grease spots, use a household
detergent. Lacquer thinner or other synthetic solvents may
damage the finish.
Save time and money. Before calling for service, check the following:

Maintenance information.
Never stop the cooling system by shutting off the
main power.
If the main power to your air conditioner is ever disconnected for more than three hours, turn off the thermostat.
Then wait for at least three more hours after the power has
been restored before turning the thermostat back on.
Failure to follow this procedure could result in damage to
your air conditioning system.
1. GENERAL INSPECTION - Examine the furnace installation for the following items:
a. All flue product carrying areas external to the furnace (i.e. chimney, vent connector) are clear and free of
obstruction.
b. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corrosion.
c. The return air duct connection(s) is physically sound,
is sealed to the furnace and terminates outside the
space containing the furnace.
d. The physical support of the furnace should be sound
without sagging, cracks, gaps, etc., around the base so
as to provide a seal between the support and the base.
e. There are no obvious signs of deterioration of the
furnace.
WARNING:
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.
Do not touch igniter. It is extremely hot. Failure to
follow this warning could result in severe burns.
2. BLOWERS - The blower size and speed determine the
air volume delivered by the furnace. The blower motor
bearings are factory lubricated and under normal operating conditions usually do not require servicing. Annual
cleaning of the blower wheel and housing is recommended
for maximum air output, and this must be performed only
by a qualified servicer or service agency.
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.
Pub. No. 32-5034-02 Page 7
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. COOLING COIL CONDENSATE DRAIN - 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.
9. AIR CIRCULATION - To ensure increased comfort,
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".
WARNING: Disconnect power to the
unit before removing the blower door. Failure to
follow this warning could result in property damage,
personal injury or death.
