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, leaves,
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
22).
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 pilot assembly also. Additional cleaning may
be needed for proper pilot operation based on use/
lack of use. A yellow tip on the pilot flame may
indicate dust and dirt in the pilot assembly. There
is a small pilot air inlet hole about from where the
pilot flame comes out of pilot assembly (see Figure
23). With unit off, lightly blow air through air inlet
hole. You may blow through a drinking straw if com-
pressed air is not available.
MAIN BURNER
Periodically inspect all burner flame holes with appli
-
ance running. All slotted burner flame holes should be
open with flame present. 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 appliance
and let cool. Remove blockage, blocked burner flame
holes will create soot.
WARNING: The injector holders (air shut-
ters) are not adjustable. Do not move injector
holders from their original positions.
