How To Care For Your Furnace

WARNING: Danger of bodily injury or death. Turn

off electric power supply at the disconnect switch,

fuse box or service panel before removing any

doors or access or service panels from the unit.

CABINET FINISH

Clean the cabinet with damp rag. Never use abrasive cleaners.

Cabinets are finished in heat resistant powder coated finish - DO

NOT refinish with wall paint.

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

obstructive furniture closer than four feet to the front of the cabinet

or two feet to either side of the cabinet.

FURNACE AREA

Keep the area near the furnace clear and free from combustible

materials, gasoline, and other flammable liquids and vapors.

ANNUAL UPKEEP NEEDED

It is recommended that a qualified service technician perform

these checks at the beginning of each heating season.

CLEANING AND OILING

Shut off electricity, and then remove cabinet door and front panel.

Clean any lint or dirt from fan blades, fan motor, and exposed air

passages. Use a brush.

Put 5 drops of SAE 20 oil in each of the two cups or oil tubes on

the fan motor, See Fig. 36, below.

PILOT BURNER

Light pilot using instructions in OPERATING YOUR FURNACE

(on pages 22 and 23, depending on your model). Leave

thermostat at lowest setting.

Pilot flame should surround 3/8 to 1/2 inch of the thermocouple

tip. Refer to Fig. 28, Page 25. If flame needs adjusting, do it as

follows:

ADJUST PILOT BURNER (Page 25 Fig 28)

1. Remove screw cover over pilot adjusting screw.

2. Insert small screwdriver, adjust flame as needed. Turn screw

counterclockwise to increase flame, clockwise to decrease.

3. Turn thermostat to highest setting. Main burners should light

quickly and smoothly. Turn thermostat to lowest setting. Main

burners should go out. Pilot should remain lit except for

electronic ignition models. See Page 23.

BURNER FLAME

Start the furnace and let it operate about 10 minutes then look at

the burner flame. Flames should be soft and blue, see Fig. 28. If

flames appear abnormal, contact the gas company or a qualified

service technician immediately.

VENTING SYSTEM

Make sure that no parts of the vent air system are blocked or

rusted. Clean or replace before using furnace.
