3. OPERATING INSTRUCTIONS

A. LP GAS OPERATION

After initial installation, servicing, or changing gas cylin- ders, etc., the gas line may contain some air which should be allowed to escape by briefly turning on the refrigerator or other gas appliances. This will ensure that the flame lights immediately. See FIG. 8 for control location and identification.

1)Open the shutoff valve of the gas bottle. Check that there is enough gas. Open any on-board shutoff valve which is in the gas line to the refrig- erator.

2)Open the lower vent at the rear of the refrigerator on the outside of the vehicle, and switch the electrical toggle switch/es (A in RM2191) and (A and E in RM2193) to the "OFF" position.

3)Turn the gas thermostat control (B) to the highest setting.

4)Depress the knob (B) of the flame failure device, turn it to position "HIGH", and hold it down while depressing the piezo igniter button (C) several times in quick succession (a click should be heard each time it is depressed).

5)Keep the knob depressed for a further 10-15 seconds.

6)Release the knob and check for flame by looking through the opening in the metal burner cover.

7)If the burner has not lit, repeat the lighting proce- dure. If the burner fails to light within a couple of attempts, contact a qualified technician or your dealer.

NOTE: The refrigerator has a flame failure device which will automatically shut off the gas to the burner if the flame is blown out. While the knob (B) is being held in, this device is temporarily inoperative.

8)If the ambient temperature is above 80°F and/or the door of the refrigerator is opened frequently the knob should be left in the "HIGH" position.

9)To terminate gas operation, turn knob (B) to the "OFF" position.

DO NOT attempt to operate the refrigerator by both gas and electricity at the same time. Always ensure that one method of operation is turned off before using the alternate energy source.
