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 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 2" from
where the pilot fl ame comes out of the pilot assem-
bly
(see
Figure 51
).
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.

INLET HOLE
The primary air inlet holes allow the proper amount
of air to mix with the gas. This provides a clean
burning fl ame. Keep these holes clear of dust, dirt,
lint and pet hair. Clean these air inlet holes prior to
each heating season. Blocked air holes will create
soot. We recommend that you clean the unit every
three months during operation and have heater
inspected yearly by a qualifi ed service person.
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 damage the pilot assembly.
1. Shut off unit, including pilot. Allow 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
Figure
50
).
3. Blow air through the ports/slots and holes in
the burner.

, 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 present. 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.
