access service panels from unit.

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.

Care – 25 Caring for Your Furnace How to Care for Your Furnace (continued) 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.
