CLEANING AND
MAINTENANCE
4. Blow air through the ports/slots and holes in
the burner.
5. 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.
6. Blow air into the primary air holes on the
injector holder.
7. In case any large clumps of dust have now been
pushed into the burner repeat steps 3 and 4.
8. Replace front log and control cover log (see
Installing Logs, page 16).
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 33). 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.

LOGS
• If you remove logs for cleaning, refer to Install-
ing Logs, page 16, 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.
