CABINET
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 the cabinet to remove dust.
LOGS
• If you remove logs for cleaning, refer to Installing Logs, page 9,
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.

Clean the pilot assembly also. A yellow tip on the pilot flame
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 28). 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.
