4. Check orifice 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
orifice 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 flame indicates dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about 2" from where the pilot flame comes out
of the pilot assembly (see Figure 81). 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.
CLEANING AND MAINTENANCE

LOGS
• If you remove logs for cleaning, refer to
Installing Logs
, page 18, 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 pres
-
ent. 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.

BURNER ORIFICE HOLDER AND
PILOT AIR INLET HOLE
The primary air inlet holes allow the proper
amount of air to mix with the gas. This pro-
vides a clean burning flame. 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 qualified
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 dam
-
age 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 orifice holder for dust and dirt
(see Figure 80).
3. Blow air through the ports/slots and holes
in the burner.
