CLEANING AND MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep con
-
trol areas, burner and circulating
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 cleaning due to
excessive lint from carpeting,
bedding material, pet hair, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result
in sooting and property damage.
Once every year a qualified agency or certified
chimney sweep should examine and clean the
venting system of fireplace.
ODS/PILOT AND BURNER
Use a vacuum cleaner or small, soft bristled
brush to clean.
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 and lint. 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 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
directions on can. If you don’t follow directions
on can, you could damage 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 34).
3. Blow air through ports/slots and holes in
burner.
4. Check orifice 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 primary air holes on orifice
holder.
6. In case any large clumps of dust have now
been pushed into burner, repeat steps 3
and 4.
Clean pilot assembly also. A yellow tip on pilot
flame indicates dust and dirt in pilot assembly.
There is a small pilot air inlet hole about 2"
from where pilot flame comes out of pilot as
-
sembly (see Figure 35). With unit off, lightly
blow air through 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
Install-
ing Logs,
page 16, to properly replace logs.
• Replace log(s) if broken or chipped (dime-
sized or larger).
BURNER PRIMARY AIR HOLES
Air is drawn into burner through the 8 holes
in brass fitting at entrance to burner. These
holes may become blocked with dust or lint.
Periodically inspect these holes for any block-
age and clean as necessary. Blocked air holes
will create soot.
