Lighting Instructions
WARNING!
Do not use a match for ignition. An ignition fl ashback
can cause burns to the hand or face. If, in an emergency, you must
use a match for ignition of the refrigerator, do not hold in the gas control
for more than fi ve 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 mode selector [292] to the GAS ( ) position (See
Art02428).
5. Turn the gas control [294] to the HI position.
6. Push and hold in the gas control [216] and in rapid succession,
push the igniter in several times. Look through the viewing win-
dow and make sure that ignition occurred. Continue to hold the
gas control in for about 15 seconds.
WARNING!
Do not hold the gas control in more than 30 seconds.
If there is no fl ame in this time, wait at least fi ve (5) minutes before you try
ignition again. If you continue to hold in the gas control, gas will collect
in the burner area. This could cause a fi re or explosion and result in
dangerous personal injury or death.
7. Turn the gas control to the amount of cooling that you wish.
8. Close the viewing window on the burner box.

Test the Gas Safety Valve
The gas safety valve is built into the control panel. As long as a
fl
ame is present, the valve is open and allows propane gas to
fl
ow
into the burner. Any loss of
fl
ame (empty propane gas tank, blow
out, etc.) closes the valve and stops the
fl
ow of propane gas.
While operating on propane gas, test the gas safety valve with an
established flame:
1. Push and turn the gas control to the OFF ( ) position.
2. After the
fl
ame is extinguished, you should hear a sharp “click”
sound within 90 seconds.
Note!
The gas safety valve should close with a sharp “click” sound.
3. Push and turn the gas control to the HI position.
4. Without pushing in the gas control, push the piezo igniter sev-
eral times rapidly in succession.
5. The burner
fl
ame should not ignite. This means that the gas
safety valve is operating correctly.
Diagnostic Pre checks
Prior to performing the diagnostic steps called out in the following
pages;
fi
rst do these important diagnostic pre-checks. In most
cases doing so, in and of itself, will remedy the problem at hand.
Make sure:
■
Door is closed and sealing correctly.
■
Unit vents are not blocked.
■
Ambient temperature is not unusually high (more than 110° F. /
43° C.)
■
Verify control panel works properly. The refrigerator is plugged
into a known working AC outlet with a voltage between 108VAC
and 132VAC.
■
Extension cords are not being used to supply AC power to the
refrigerator.
■
The refrigerator is connected to a known working DC power
supply and/or battery supplying between 10.5 and 15.4VDC.
■
Propane gas is available to the refrigerator and is regulated
between 10.5 and 11.5”WC (Inches of Water Column).
■
The airflow through the intake and exhaust vents is not blocked
and the ventilation baffles are constructed correctly.
If the unit does not operate after these pre checks perform
diagnostics outlined in the “Troubleshooting” section of this manual.
Troubleshooting
Examine the cooling unit for leaks.
Warning!
If you think that the cooling system has a leak, do not
operate the refrigerator. Replace the cooling unit before operating the
refrigerator. If you smell ammonia, the cooling unit has a leak and must
be replaced. If you see a yellow powder or residue anywhere at the rear
of the refrigerator or in the enclosure, the cooling unit has a leak and must
be replaced.
Diagnostic Procedures
Determine if the cooling problem occurs while the refrigerator is set
to propane gas, AC electric, and DC electric to see if the selected
energy source is operating correctly:
1. Select an energy source. Within 20 minutes of starting the
refrigerator, touch the outside of the insulation sleeve.
CAUTION!
Touch only the outside of the insulation sleeve. During
normal operation, some tubes of the cooling unit are hot. Do not touch
any tubes of the cooling unit.
