Cleaning and Maintenance

WARNING: Turn off heater and let cool before cleaning.

CAUTION: You must keep control

areas, burner, and circulating air pas- sageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

CLEANING ODS/IGNITOR AND BURNER

Clean with a vacuum cleaner.

CLEANING MAIN AIR INLET HOLE

We recommend that you clean the unit every three months or after 2500 hours of operation. We also recom- mend 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. You can use a vacuum cleaner in the blow position. 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 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 17).

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 been pushed into the burner, repeat steps

3and 4.

Clean the pilot assembly also. A y e l l o w t i p o n t h e p i l o t f l a m e indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 18). 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.

Air Passageways

Use a vacuum cleaner or pressurized air to clean.

EXTERIOR

Use a soft cloth dampened with a mild soap and water mixture. Wipe t h e c a b i n e t t o r e m o v e d u s t .

LOGS

If you remove logs for cleaning, refer to Installing Logs , page 15, to properly replace logs.

Replace log(s) if broken or chipped (dime-sized or larger).

MAIN BURNER

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 o p e n w i t h a s m a l l b l u e f l a m e present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Either remove blockage or replace burner. Blocked burner flame holes will create soot.
