WARNING: Turn off heater and let cool before cleaning.
CAUTION: You must keep control areas, burners, and circulating
air passageways of heater clean. Inspect these areas of heater be
-
fore each use. Have heater inspected yearly by a qualified 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 opening 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
opening prior to each heating season.
Blocked air
opening 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 compressed air in a can. You can use a
vacuum cleaner in the blow position. 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 the unit, including the pilot. Allow the unit to cool for at least
thirty minutes.
2. Inspect burner, pilot, and primary air inlet opening on injector holder for
dust and dirt (see Figure 26).
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.
5. Blow air into the primary air opening 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
27). 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.
