We also recommend that you keep the burner
tube and pilot assembly clean and free of dust
and dirt. To clean these parts we recommend
using compressed air no greater than 30 PSI.
Your local computer store, hardware store or
home center may carry compressed air in a
can. If using compressed air in a can, please
follow the directions on the can. If you don’t
follow directions on the can, you could dam-
age the pilot assembly.
1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet
holes on orifi ce holder for dust and dirt
(see Figures 24 and 25).
CLEANING AND MAINTENANCE
Continued
3. Blow air through the ports/slots and holes
in the burner.
4. Check the orifi ce 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.
5. Blow air into the primary air holes on the
orifi ce holder.
6. In case any large clumps of dust have now
been pushed into the burner repeat steps
3 and 4.
Clean the pilot assembly also. A yellow tip
on the pilot fl ame indicates dust and dirt in
the pilot assembly. There is a small pilot air
inlet hole about two inches from where the
pilot fl ame comes out of the pilot assembly
(see Figure 25).
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
In-
stalling Logs,

, to properly replace
logs.
• Replace log(s) if broken or chipped (dime-
sized or larger).
MAIN BURNER
Periodically inspect all burner fl ame holes with
the heater running. All slotted burner fl ame
holes should be open with yellow fl ame pres-
ent. All round burner fl ame holes should be
open with a small blue fl ame present. Some
burner fl ame holes may become blocked by
debris or rust, with no fl ame present. If so,
turn off heater and let cool. Remove blockage.
Blocked burner fl ame holes will create soot.
