CLEANING

Figure 20 - Pilot Air Inlet Hole

Pilot Assembly

Pilot Air Inlet

CABINET

Air Passageways

Use pressurized air to clean.

Exterior

Use a soft cloth dampened with a mild soap

and water mixture. Wipe the cabinet to re-

move dust.

and dirt. To clean these parts we recommend

using compressed air no greater than 30 PSI.

Your local computer store, hardware store or

home center may carry compressed air in a

can. If using compressed air in a can, please

follow the directions on the can. If you don't

follow directions on the can, you could dam-

age the pilot assembly.

1. Shut off the unit, including the pilot. Allow

the unit to cool for at least thirty minutes.

2. Inspect burner, pilot for dust and dirt.

3. Blow air through the ports/slots and holes

in the burner.

4. Never insert objects into the pilot tube.

Clean the pilot assembly also. A yellow tip on

the pilot ame indicates dust and dirt in the

pilot assembly. There is a small pilot air inlet

about 2" from where the pilot ame comes out

of the pilot assembly (see Figure 20). With

the unit off, lightly blow air through the air

inlet. You may blow through a drinking straw

if compressed air is not available.

WARNING: Turn off heater

and let cool before cleaning.

CAUTION: You must keep

control areas, burner and circu-

lating air passageways of heater

clean. Inspect these areas of

heater before each use. Have

heater inspected yearly by a

qualied service person. Heater

may need more frequent clean-

ing due to excessive lint from

carpeting, bedding material, pet

hair, etc.

WARNING: Failure to keep

the primary air opening(s) of

the burner(s) clean may result in

sooting and property damage.

ODS/PILOT AND BURNER

Use a vacuum cleaner, pressurized air or

small, soft bristled brush to clean.

BURNER PILOT AIR INLET

The primary air inlet holes allow the proper

amount of air to mix with the gas. This pro-

vides a clean burning ame. Keep these holes

clear of dust, dirt and lint. Clean these air inlet

holes prior to each heating season. Blocked

air holes will create soot. We recommend that

you clean the unit every three months during

operation and have heater inspected yearly

by a qualied service person.

We also recommend that you keep the burner

tube and pilot assembly clean and free of dust
