Check burner flame
Check burner flame for proper
appearance. The flame should be
light blue with no yellow at the tip.
Check the LP gas pressure
The LP gas pressure should be checked and the main regulator
readjusted if pressure is incorrect. The correct operating pres-
sure is 11 inches of water column. The correct place to take the
LP gas pressure is at the test port just ahead of the burner jet.

Inspect the flue baffle
It should be reasonably clean and free of soot. Heavy soot for-
mation indicates improper 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.
A) to "OFF" position.
2. Turn the knob (
3. Remove cover from the burner housing.
4. Disconnect the wire from the high voltage electrode.
5. Remove the burner mounting screw and remove the
burner assembly.
6. 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 prop-
erly clean soot and scale out of the flue tube. Replace
the flue baffle.
7. Clean burner tube with a brush. Blow out burner with
compressed air.
8. 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.

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
and the thermocouple is positioned properly (tip of
thermocouple extends over two slots of burner).
10. Be sure to reconnect the wire to high voltage elec-
trode. Check the electrode for proper location and
gap.

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
depressed to allow gas pressure to flow to the
burner jet. be sure to apply the leak check
solution before depressing the safety shut-off.
DO NOT depress safety shutoff for over 30
seconds.
!
EXPLOSION hAZArD. Never use an open
flame to check for gas leaks. Failure to heed this
warning could cause an explosion resulting in
death or severe personal injury.
12. 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.
13. Connect 120 volt power cord to the outlet.
14. Check LP gas safety shutoff.
