The LP gas pressure should be checked and the
main regulator readjusted if pressure is incorrect. 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. 5).
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 both require cleaning in the following manner:
Unplug the refrigerator power cord from the 120 volt
AC outlet.
Turn the knob “A” to “OFF” position.
Remove cover from the burner housing.
Disconnect the wire from the high voltage electrode.
Remove the burner mounting screw and remove the
burner assembly.
Remove the wire and 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.
Clean burner tube with a brush. Blow out burner with
compressed air.
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. Re-install and tighten burner jet.
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.

trode. Check the electrode for proper location and
gap. (See FIG. 6).

11. The gas fittings on the refrigerator need to be
checked for leaks. Turn the knob “A” to position
“GAS”. Apply a non-corrosive bubble solution to the
fitting and observe for leaks. The safety valve will not
allow gas pressure to any connections between it and
the burner jet. These fittings must be checked before
burner is lighted.
The safety shut-off must be manually de-
pressed to allow gas pressure to flow to the
burner jet. Be sure to apply the leak check solu-
tion before depressing the safety shut-off. DO
NOT allow any open flame, sparks, smoking,
etc., in the area of the test. DO NOT depress
safety shut-off for over 30 seconds.

Allow 10 minutes for the LP gas to leave the burner
area. Light the burner according to the Operating
Instructions, section Gas Operation. Allow burner to
run 5 minutes.
Connect 120 volt power cord to the outlet.
Check LP gas safety shut-off. See page 3.
9. 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
