DThe 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).

E.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:

1.Unplug the refrigerator power cord from the 120 volt AC outlet.

2.Turn the knob “A” to “OFF” position.

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 properly 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.

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.

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. (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.

12Allow 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 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
