CARE AND MAINTENANCE
CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
We recommend that you clean the unit every three months or after 2,500 hours of operation.
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.
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
holes on injector holder for dust and dirt
(see Fig. 48).
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 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 the pilot assembly also.
WARNING
: Failure to keep primary air openings of burners clean may result in sooting and
property damage.
CAUTION : You must keep control 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.
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 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 2,500 hours of operation or every three months.
MAIN BURNER
Periodically inspect all burner flame holes with the heater running. 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 heater and let cool, either remove blockage or replace
burner. Blocked burner flame holes will create soot.
