CLEANING AND MAINTENANCE
2. Inspect burner, pilot and primary air inlet
holes on injector holder for dust and dirt
(see Figure 27).
3. Blow air through the ports/slots and holes
in the burner.
4. Check injector holder located at end of
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
injector 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 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 28). 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.

WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner and circu
-
lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a
qualified service person. Heater
may need more frequent clean
-
ing due to excessive lint from
carpeting, pet hair, bedding
material, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result in
sooting and property damage.
BURNER INjEcTOR 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.
Note: Removing the
rear panel (Figure 5, page 9) and top grate(s)
of your stove will make cleaning easier.
1. Shut off unit, including pilot. Allow unit to
cool for at least thirty minutes.
