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 locati-
on 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 refrigerator.
2) Open the lower vent at the rear of the refrigerator on
the outside of the vehicle, and switch the electrical
toggle switches A and B to the "OFF" position.
3) Turn the gas thermostat control (F) to the highest
setting.
4) Depress the knob (D) of the flame failure device, turn
it to position “ON”, and hold it down while depres-
sing the piezo igniter button (E) 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 procedure.
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 bur-
ner if the flame is blown out. While the knob (D) 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
(F) should be left in higher position.
9) To terminate gas operation, turn knob (D) to the
"OFF" position.
8
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.
