into the burner repeat steps 3 and 4.
Clean pilot assembly also. Additional cleaning may be needed
for proper pilot operation based on use/lack of use. A yellow tip
on the pilot flame may indicate dust and dirt in the pilot assem-
bly. There is a small pilot air inlet hole about from where the
pilot flame comes out of pilot assembly (see Figure 32). With
unit off, lightly blow air through air inlet hole. You may blow
through a drinking straw if compressed air is not available.

LOGS
• If you remove logs for cleaning, refer to Installing Logs and
Lava Rock, page 11, to properly replace logs.
• Replace log(s) if broken or chipped (dime-sized or larger).
MAIN BURNER
Periodically inspect all burner flame holes with appliance running.
All slotted burner flame holes should be open with 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 appliance
and let cool. Remove blockage, blocked burner flame holes will
create soot.
WARNING: The injector holders (air shut-
ters) are not adjustable. Do not move injector
holders from their original positions.
