Cleaning Burner Injector Holder and Pilot Air Inlet Hole
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the fitting at the
burner entrance. These holes may become blocked with dust or lint.
Periodically inspect these holes for any blockage and clean if
needed. Blocked air holes will create soot.
MAIN BURNER
Periodically inspect all burner flame holes with the fireplace run-
ning. 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 become
blocked by debris or rust, with no flame present. If so, turn off
fireplace and let cool. Remove blockage, blocked burner flame
holes will create soot.
NOTICE: Do not mistake orange flames with yellow
tipping. Dirt or other fine particles enter the fireplace
and burn causing brief patches of orange flame.
WARNING: If yellow tipping occurs, your fireplace
could produce increased levels of carbon monoxide.
BURNER FLAME PATTERN
Figure 45 shows a correct burner flame pattern. Figure 46 shows an
incorrect burner flame pattern. The incorrect burner flame pattern
shows the flame higher consistently higher than 1 inch above the logs.
If burner flame pattern is incorrect, as shown in Figure 46
• turn heater off (see To Turn Off Gas To Appliance, page 19)
• see Troubleshooting, pages 23 through 25

CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace and let cool before
cleaning.
CAUTION: You must keep control areas, burner,
and circulating air passageways of fireplace clean.
Inspect these areas of fireplace before each use.
Have fireplace inspected yearly by a qualified service
person. Fireplace may need more frequent cleaning
due to excessive lint from carpeting, bedding mate-
rial, pet hair, 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 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
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 com-
pressed air in a can. You can use a vacuum cleaner in the blow
position. If using compressed air in a can, please follow the direc-
tions on the can. If you don't follow directions on the can, you could
damage the pilot assembly.
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 47 and Figure 48, page 22).
3. Blow air through the ports/slots and holes in the burner.
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.
