INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the proper flame height.
Alterations may have occurred during shipping and handling.
Call a qualified service person to readjust the pilot if necessary.
The height of the thermopile must be 3/8" to 1/2" above the
pilot flame as shown in
Figure 27
. The thermocouple must be
at a height of about 1/8" above the pilot flame. The flame from
the pilot burner must extend beyond both the thermocouple
and thermopile.
If your pilot assembly does not meet these requirements:
• turn fireplace off

burned by appliance, causing brief patches of
orange flame.

CLEANING AND MAINTENANCE
WARNING: Turn off appliance and let cool
before cleaning.
CAUTION: You must keep control areas,
burners and circulating air passageways of ap
-
pliance clean. Inspect these areas of appliance
before each use. Have appliance inspected
yearly by a qualified service person.
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 provides 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 appliance 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 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 injector
holder for dust and dirt
(see
Figure 30, Page 17
).
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.
