Owner’s Manual 7
The gas safety valve [3] is built into the control panel. As long as
a flame is present, the valve is open and allows propane gas to
flow into the burner. Any loss of flame (empty propane gas tank,
blow out, etc.) closes the safety valve and stops the flow of
propane gas.
The flame indicator [4] shows if a flame is present in the burner.
Ignition - propane gas operation:
1. Open the valve at the propane gas storage tank.
2. Turn the thermostat [1] to the 5 position.
3. Turn the selector switch [2] to the propane gas position ( ).
4. Push and hold in the safety valve [3] for about five seconds:
- The refrigerator automatically ignites the gas at the burner.
WARNING: Do not hold in the safety valve 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 in the safety valve, gas will collect in the burner
area. This could cause a fire or explosion and result in
dangerous personal injury or death.
- When a flame is present and the flame indicator [4]
illuminates, release the safety valve.
- If the flame indicator does not illuminate, do this step again.
5. Turn the thermostat to the temperature setting that you wish.
Do a test of the gas safety valve:
With an established flame in GAS mode:
1. Close the manual gas shutoff valve [2] of the refrigerator
(See Art00975].
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.

Operating the Refrigerator Controls
(N510 models )
Control panel:
The refrigerator control panel (see Art10562) is above the
refrigerator door. A 12 volt DC power supply is necessary for the
control functions of the refrigerator to operate. The refrigerator
receives DC power from the 12 volt system of the vehicle; either
an auxiliary battery, a converter, or the vehicle engine battery.
The ON / OFF button [1] starts and shuts down the refrigerator:
- To turn on the refrigerator, push and release the ON / OFF
button.
- To turn off the refrigerator, push the ON / OFF button for two
seconds and then release.
