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 41).
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.
CLEANING AND
MAINTENANCE
Continued
Clean the pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot as
-
sembly. There is a small pilot air inlet hole about
two inches from where the pilot flame comes out
of the pilot assembly (see Figure 42). 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.
LOGS
• If you remove logs for cleaning, refer to Install-
ing Logs, page 17, to properly replace logs.
• Replace log(s) if broken or chipped (dime-sized
or larger).
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.
WIRING DIAGRAMS
Note: For proper operation of optional accessories,
the wires from the switch to the control must be con-
nected exactly as shown in Figures 43 and 44.
CAUTION: Label all wires
prior to disconnection when
servicing controls. Wiring errors
