Installation and Owner’s Guide 4
- Turn the gas control to LOW COOL position.
- Keep the refrigerator full.
- Put foods that are more likely to freeze on the lower shelf.
The gas control has a gas safety valve built into it. As long as a
flame is present, the safety valve is open and allows propane gas
to flow to the burner. Any loss of flame (empty gas tank, blow
out, etc.) closes the safety valve and stops the flow of propane
gas.
The piezo lighter [216] makes a spark which ignites the flame at
the burner.
The 3 Amp fuse [220] protects the AC wiring of the refrigerator.
The 20 Amp fuse [223] (model 323) protects the DC wiring of the
refrigerator.
Ignition - propane gas operation:
WARNING: Do not us a match for ignition. An ignition
flashback can cause burns to the hand or face. If, in an
emergency, you must use a match for ignition of the refrig-
erator, do not hold in the gas control for more than five or
ten seconds at a time and use the longest match possible.
1. Open the lower intake vent to get access to the rear of the
refrigerator.
2. Open the valve at the propane gas storage tank.
3. Open the viewing window on the burner box .
4. Turn the energy selector switch [207] to the GAS position (See
Art00953).
5. Turn the gas control [233] to the HIGH COOL position.
6. Push and hold in the gas control.
- In rapid succession, push the igniter [216] in several times.
- Look through the viewing window and make sure that ignition
occurred.
WARNING: Do not hold the gas control in for more than
30 seconds. If there is no flame in this time, wait at least
five minutes before you try ignition again. If you continue
to hold the gas control in, gas will collect in the burner
area. This could cause a fire or an explosion and result in
dangerous personal injury or death.
- Continue to hold the gas control in for about 15 seconds only.
7. Turn the gas control to the amount of cooling that you wish.
8. Close the viewing window on the burner box.

Do a test of the gas safety valve:
With an established flame in GAS mode:
1. Close the manual gas shutoff valve [218] of the refrigerator
(See Art00952].
2. After the flame is extinguished, you should hear a sharp “click”
sound within three minutes.
NOTE: The gas safety valve should close with a sharp “click“
sound.
3. Open the manual gas shutoff valve of the refrigerator.
4. Without pushing in the gas control, push the igniter several
times rapidly in succession. The burner flame should not
ignite. This means that the gas safety valve is working
correctly.
Start up - AC operation:
- Make sure that 120 volts AC is available and the 3 Amp fuse
[220] is working correctly.
- Turn the energy selector to the AC position.
- Turn the gas control to the OFF position.
Start up - DC operation (model 323 only):
- Make sure that 12 volts DC is available and the 20 Amp fuse
[223] is working correctly.
- Turn the energy selector to the DC position.
- Turn the gas control to the OFF position.
The refrigerator receives its DC power from the 12 volt system
of the vehicle; either the vehicle engine battery or an auxilliary
(house) battery. The 12 volt system of the vehicle supplies DC
power only to the refrigerator but also to any other DC appliances
of the vehicle. When operating on DC, the refrigerator has a high
current draw and can cause a rapid battery discharge.
DC operation precautions:
This refrigerator is made to operate on DC power while your
vehicle is “in transit” and AC power or propane gas sources are
not available. Operate the refrigerator on DC power only when
the vehicle engine is running.
For the refrigerator to operate correctly on DC power, the battery
must be maintained in a fully charged condition.
For the battery to be fully charged at all times during refrigerator
operation on DC, the vehicle engine must be running and the
battery charging system must be in good operating condition.
