LOGS
• If you remove logs for cleaning, refer to
Installing Logs,

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 34
).
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.
