ANNUAL UPKEEP NEEDED
It is recommended that a qualified service technician perform
these maintenance checks at the beginning of each heating
season.
CABINET FINISH
Clean cabinet with damp cloth. Never use abrasive cleaners.
Cabinets are finished with heat resistant powder paint. Never
refinish or paint.
FURNACE AREA
Keep the area near the furnace clear and free from combustible
materials, gasoline and other flammable liquids and vapors.
COMBUSTION AND VENTILATION AIR
The combustion and ventilation air supply must not be blocked.
Do not put anything in or on the furnace cabinet. For better
circulation and more effective heating, do not place obstructions,
furniture or other items closer than four&feet in front of the
furnace or two&feet from each side of the furnace.
CLEANING BLOWER (IF APPLICABLE)
Shut off electricity. Clean any lint or dirt from fan blades, fan
motor and exposed air passages.
PILOT BURNER

1. Insert small screwdriver into the pilot adjusting screw
Figure 23. Adjust flame as needed. Turn screw
counterclockwise to increase flame, clockwise

CLEANING THE BURNER COMPARTMENT
Because cold air is attracted to the flame during furnace
operation, a buildup of lint from carpeting, bedding, dust, etc.
in the burner area will occur. It is necessary to clean this area
regularly. Use a vacuum cleaner with a narrow attachment to
reach small areas. Be careful in and around the pilot. A change
in its adjustment could be made if moved during cleaning. A
properly adjusted burner with nearly all gases will produce a
flame which has clear blue cone having a bluish-red or bluish-
violet outer mantle.
Open burner compartment door.
Shut off gas supply to furnace.
Disconnect gas line inside cabinet at ground joint union
fitting. Figure 24
Remove (2) screws securing burner pan assembly to
inner liner.
Pull burner pan assembly forward approximately
1/2-inch and drop down to expose the top of the burner.
Clean all foreign materials from the top of the burner.
After cleaning, replace burner pan assembly by
reversing above procedure.
