BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
We recommend that you clean the unit ev-
ery 2,500 hours of operation or every three
months. 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 PSl. 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 us-
ing 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 for dust and dirt (see
Figure 30).
3. Blow air through the ports/slots and holes
in the burner. Also clean the pilot assembly.
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.
CAUTION: Never use a wire,
needle, or similar object to clean
ODS/pilot. This can damage
ODS/ pilot unit.
Use a vacuum cleaner, pressurized air, or a
small, soft bristled brush to clean.
A yellow tip on the pilot ame indicates dust
and dirt in the pilot assembly. There is a small
pilot air inlet hole about 2" from where the
pilot ame comes out of the pilot assembly
(see Figure 31). With the unit off, lightly blow
