The correct operating pressure is 11 inches of water

column. The correct place to take the LP gas pres-

sure is at the test port just ahead of the burner jet.

(See FIG. 12).

E. Inspect the flue baffle. It should be reasonably clean

and free of soot. Heavy soot formation indicates im-

proper functioning of the burner. The flue and burner

both require cleaning in the following manner:

1. Unplug the refrigerator power cord from the 120 volt

AC outlet. (See FIG. 3).

2. Disconnect or shut off the 12 volt power to the refrig-

erator.

3. Turn manual shutoff valve to OFF. (See FIG. 1).
4. Remove cover from the burner housing. (See FIG. 1).
5. Disconnect the wire from the high voltage electrode.
6. Remove the burner mounting screws and remove the

burner assembly. (See FIG. 12).

7. Remove the wire and the flue baffle from the top of

flue tube. Clean the flue from the top using a flue

brush. Blowing compressed air into the flue will not

properly clean soot and scale out of the flue tube.

Replace the flue baffle.

8. Clean burner tube with a brush. Blow out burner with

compressed air.

9. Before removing 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 burner jet.

NOTE:

 The color of the flame shall be clear blue

over the slots of the burner. (See FIG. 13).

DO NOT use a wire or pin when cleaning the burner

jet as damage can occur to the precision opening.

This can cause damage to the refrigerator or create

a fire hazard.

! WARNING

10. Reinstall burner, being careful that the end of the

burner fits into the slot on the burner bracket. Check

to make sure slots are centered under the flue tube

and the thermocouple is positioned properly (tip of

thermocouple extends over two slots of burner).

11. Be sure to reconnect the wire to high voltage elec-

trode. Check the electrode for proper location and

gap. (See FIG. 14).

12. Turn on manual gas shutoff valve and check all fit-

tings for leaks.

13. Connect 120 volt power cord to the outlet and re-

connect or turn on the 12 volt DC power.

14. Check LP gas safety shutoff. See page 6.
