BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the fitting at the burner entrance. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean if needed. Blocked air holes will create soot.

Periodically inspect all burner flame holes with the heater running.All slotted burner flame holes should be open with yellow flame present.All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Remove blockage, blocked burner flame holes will create soot.

Cleaning and

Maintenance

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 heaterinspectedyearlybyaquali- fied service person. Heater may need more frequent cleaning 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.

Cleaning Burner Injector

Holder and Pilot Air Inlet Hole

The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning flame. Keep these holes clear of dust, dirt, lint, and pet hair. 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 qualified service person.

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. You can use a vacuum cleaner in the blow position. If using com- pressed air in a can, please follow the directions on the can. If you don't follow directions on the can, 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 32).

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 hair 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.
