Propane Gas Connections
The refrigerator operates on propane gas at a pressure of 10.5
inches Water Column min. to 11.5 inches Water Column max.
Be very careful when working on or near
the propane gas system.
■ Do not smoke, or use an open flame near the propane gas
system.
■ Do not use an open flame to examine for leaks.
■
Do not connect the refrigerator to the propane gas tank without
a pressure regulator between them.
ATTENTION
!
WARNING
■
To avoid possible propane gas leaks, always use two wrenches
to tighten or loosen the propane gas supply line connections.
■
Leaking propane gas can ignite or explode and result in danger-
ous personal injury or death.
Do not allow the leak detecting solution
to touch the electrical components. Many
liquids are electrically conductive and can
cause a shock hazard, electrical shorts,
and in some cases fire.
Leak Test-Detergent
Using a solution of liquid detergent and water:
■
Examine the propane gas supply system for leaks: make sure
the propane gas supply line and all gas connections have no
leaks. Do not use any liquid that contains ammonia.

WARNING
Electrical Connections
120 Volts AC Electrical Connection
The refrigerator is equipped with a three-prong plug for protection
against shock hazard and must be connected into a recognized
three-prong attachment receptacle. The cord must be routed so as
not to come in contact with the burner cover, flue pipe or any other
component that could damage the cord insulation.
Do not remove (cut) grounding plug from
the refrigerator AC power cord. Removal
of this prong can result in a severe electri-
cal shock, as well as voiding the refrigera-
tor’s electrical certification and warranty.
■
Verify AC power cord is in a grounded three-prong receptacle.
■
Verify receptacle is within easy reach of the lower intake vent.
■ Verify power cord does not touch the burner cover, the flue
pipe, or any hot component that could damage the insulation of
the power cord.
12 Volts DC Electrical Connection
The refrigerator controls require 12 volt DC to operate. The mini-
mum control voltage is 10.5 volts DC. The maximum control volt-
age is 16.0 volts DC.
Polarity
The correct polarity of the DC leads to the main control board
(power board) connections is:
■
The 12 volt DC (positive) supply wire from the battery must be
connected to the terminal marked “12 VDC” of the main control
board (power board). On 3-way models, this connection is made
to the DC control board terminal marked “12 VDC” .
■
The 12 volt DC (ground) supply wire from the battery must be
connected to the terminal marked “GND” of the main control
board (power board). On 3-way models, this connection is made
to the DC control board terminal marked “GND”.
