CLEANING AND

MAINTENANCE

Continued

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 in- jector holder.

6.In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4 on page 24.

Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and dirt in the pilot as- sembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 42). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if com- pressed air is not available.

LOGS

•If you remove logs for cleaning, refer to In- stalling Logs, pages 16 through 19, 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 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.
