LOGS
• If you remove logs for cleaning, refer to Installing Logs, starting
on Page 14, 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 indi-
cates 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 49). 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.
