WARNING: Turn off heater and let cool before cleaning.
CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect
these areas of heater before each use. Have heater inspected yearly by a qualied service technician. Heater
may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
The primary air inlet holes allow the proper amount of air to mix with the gas. This provides 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 2500 hours of operation or every three months.
We also recommend that you keep the burner tube and pilot assembly clean and free of 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, or you can use a vacuum cleaner in the blow position. If using com-
pressed air in a can, please follow the directions or on the can, or you could damage 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, and primary air inlet holes on injector holder for
dust and dirt (see Figure 25).
3. Blow air through the ports/slots and holes in the burner.
4. Check the injector holder located at the end of the burner tube again.
Remove any large particles of dust, dirt, lint, or pet hairs with a soft
cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector holder.
6. In case any large clumps of dust have now been pushed into the burner
repeat steps 3 and 4.
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 hole about two
inches from where the pilot ame comes out of the pilot assembly (see Fig-
ure 26). With the unit off, lightly blow air through the air inlet hole. You may
blow through a drinking straw if compressed air is not available.
MAIN BURNER
Periodically inspect all burner ame holes with the heater running. All slot
burner ame holes should be open with yellow ame present.
All round burner ame holes should be open with a small blue ame
present. Some burner ame holes may become blocked by debris or
rust, with no ame present. If so, turn off heater and let cool.
Remove the blockage or Contact customer service for assistance. Blocked
burner ame holes will create soot.
