CLEANING THE FLUE BAFFLE AND BURNER
Inspect the flue baffle. It should be reasonably clean and free of soot. Heavy soot formation indicates improper functioning
of the burner. The flue and burner require cleaning in the following manner:
1. Unplug the refrigerator power cord from the 120 V
AC outlet.
2. Disconnect or shut off the 12V DC power to the
refrigerator.
3. Turn off the manual shutoff valve.
4. Remove the cover from the burner housing.
5. Disconnect the wire form the high voltage electrode.
6. Remove the burner mounting screws and then, re-
move the burner assembly.
7. Remove flue cap from the top of the flue tube. Lift
out the wire and spiral baffle. Using a flue brush,
clean the flue from the top. (Blowing compressed air
into the flue will not properly clean soot and scale
out of the flue tube.)
8. Replace the flue baffle.
9. Clean the burner tube with a brush. Blow out the
burner with compressed air.
10. Before removing the burner jet:
Clean burner area of soot and scale that fell out of
-
flue tube.
- Remove the burner jet.
Soak the jet in wood alcohol and blow it out with
-
compressed air.
- Reinstall and tighten the burner jet.
! WARNING
Do not use a wire or pin when cleaning the burner
jet as damage can occur to the precision opening.
This could be extremely hazardous!
MAINTENANCE & SERVICE

11. Carefully reinstall the burner. Make sure that the end of the
burner fits into the slot on the burner bracket. Verify that
the slots are centered under the flue tube and the thermo-
couple is positioned properly (tip of thermocouple extends
over two slots of burner).
The color of the flame should
be clear blue over the slots of
the burner.
12. Be sure to reconnect the wire to the high voltage electrode.
Check the electrode for proper location and gap.

turn on the 12 V DC power.
15. Check the LP gas safety shutoff.
