Checking the connections

LP gas is a flammable gas which has the potential to create a hazard. Do not smoke or create sparks when working on or near the LP gas system.

!

WARNING

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.

1.Check all connections in the LP gas system for gas leaks. The LP gas supply must be turned on.

2.Apply a non-corrosive bubble solution to all LP gas connections. The appearance of bubbles indicates a leak and should be repaired immediately!

Checking the control system

Check the control system by connecting/disconnecting the 120V AC power, starting/stopping the engine, etc.

Checking the LP gas pressure

The LP gas pressure should be checked and the main regulator readjusted if the pressure is incorrect. The correct operating pressure is 11 inches of water column. Measure the LP gas pressure at the test port, just ahead of the burner jet.

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. Turn off the refrigerator. Unplug the power cord from the 120V AC outlet. Disconnect the wires or shut off the 12V DC power supply to the refrigerator.

2. Turn off the manual shutoff valve.

3.Remove the cover from the burner housing. Remove the burner mounting screws and then the burner as- sembly.

4.Remove the wire and flue baffle from the top of the flue tube. 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.)

5.Put back the flue baffle.

6.Clean the burner tube with a brush. Blow out the burner with compressed air.

7.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

FIRE HAZARD. Do not use a wire or pin when cleaning the burner jet as damage can occur to

the precision opening. Failure to heed this warn- ing could cause fire resulting in personal injury.

8.Reinstall the burner. Ensure 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 thermocouple is positioned properly (tip of thermo- couple extends over two slots of burner).
