C.Check the AMES control system by connecting/dis- connecting 120 volt AC power, start/stop the engine, etc. Compare the operation with the operation de- scribed in section Operating Instructions.

D.The LP gas pressure should be checked and the main regulator readjusted if pressure is incorrect. The cor- rect operating pressure 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. (See FIG. 9).

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. 8).

2.Disconnect or shut off the 12 volt DC power to the refrigerator.

3.Turn manual shutoff valve to OFF. (See FIG. 1 & 9).

4.Remove cover from the burner housing. (See fig. 1).

5.Disconnect the wire from the high voltage electrode.

6.Remove the burner mounting screw and remove the burner assembly. (See FIG. 9).

7.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.

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.

! WARNING

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.

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).

NOTE: The color of the flame shall be clear blue over the slots of the burner. (See FIG. 10).

12.Turn on manual gas shutoff valve and check all fit- tings for leaks with soapy water.

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 7.

F.FUSES

The refrigerator is equipped with 3 fuses, two fuses in the power module and one in-line blade fuse.

Power module

To replace fuse(s) proceed as follows.

1.Disconnect the wall plug, and the 12 volt wires.

2.Remove the power module cover. See FIG. 1.

3.Snap the fuse out of the fuse holder.

4.Fit a new fuse in to the fuse holder.

5.Replace the power module cover.
