CLEANING AND
MAINTENANCE
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 quali-
fied service person. Heater may
need more frequent cleaning due
to excessive lint from carpeting,
pet hair, bedding material, etc.
CLEANING 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 in-
spected 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 recom-
mend using compressed air no greater than
30 PSI. Your local computer store, hard-
ware store, or home center may carry com-
pressed air in a can. You can use a vacuum
cleaner in the blow position. If using com-
pressed air in a can, please follow the direc-
tions on the can. If you don't follow direc-
tions on the can, you could damage the pilot
assembly.
Note:
Removing the rear panel
(Figure 5, page 8) and top grates of your
stove will make cleaning easier.
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 injector holder for dust
and dirt (see Figure 35).
3.
Blow air through the ports/slots and
holes in the burner.

Burner Tube
4.
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.
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 two inches from where the
pilot flame comes out of the pilot assembly
(see Figure 36). 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
Installing Gas Log Heater into Stove,
page 10, 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 be-
come blocked by debris or rust, with no
flame present. If so, turn off heater and let
cool. Either remove blockage or replace
burner. Blocked burner flame holes will
create soot.
Review your video included with your heater
for additional cleaning instructions.
TRANSPORTING STOVE
Porcelain enamel coatings contain glass and
are brittle. To prevent cracking of the porce-
lain finish, do not transport stove with top
grates in place.
