*Recommended
**Some furnaces may have 2 filters
d. a washable filter, wash filter (if dirty) in sink, bathtub,
or outside with a garden hose. Always use cold tap
water. A nfild liquid detergent may be used if necessary.
Spray water through filter in the opposite direction of
airflow. Allow filter to dry.
5. Reinstall clean air filter.
6. Replace filter cabinet door.
7. Turn on electrical supply to furnace (See Fig. 10).
NOTE: If side return ducts are used, 2 filters may be required in
some models. The procedure listed above may be used to remove
side filters.
UNIT OPERATION HAZARD
Failure to follow this caution may result in personal iniury.
Failure to follow this warning could result in personal iniury
or death.
For proper and safe operation the furnace needs air for
combustion and ventilation. Do not block or obstruct air
openings on the furnace, air opening to the area in which the
furnace is installed, and the space around the furnace.
PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury.
Use care when cutting support rods in filters to protect against
flying pieces and sharp rod ends. Wear safety glasses, gloves,
and appropriate protective clothing.
Filters may be field modified by cutting filter material and support
rods (3) in filters. Alternate sizes and additional filters may be
ordered from your dealer.
COMBUSTION AREA AND VENT SYSTEM
Inspect the combustion area and vent system before each heating
season. An accumulation of dirt, soot, or rust can mean a loss of
efficiency and improper performance. Buildups on the main
burners can cause faulty firing. This "delayed ignition" is
characterized by an alarnfingly loud sound.
NOTE: If your furnace makes a loud noise when the main burners
are ignited, shut down the furnace and call your servicing dealer.
Use your flashlight and follow these steps for inspecting the
combustion area and vent system of your furnace:
1. Turn off electrical supply to the furnace and remove the
access door. (See Fig. 5 and 6.)
2. Carefully inspect the gas burner for dirt, rust, or scale.
Inspect the elbow, flue connection area, and the vent pipe
for rust.
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal iniury
or death.
For proper and safe operation the furnace needs air for
combustion and ventilation. Do not block or obstruct air
openings on the furnace, air opening to the area in which the
furnace is installed, and the space around the furnace.
