WARNING
This refrigerator is not intended to be operated as a
Free-Standing refrigerator (i.e. the products of combus-
tion must be completely isolated from the living area)
or installed in such a way as to conflict with these
installation instructions. Unapproved installations could
result in safety risks or performance problems.
The model 3163 is designed for built-in installation and
operates on propane gas, 120 volts AC, or 12 volts DC.
Interior Ventilation
The refrigerator's cooling system requires a continual
air flow to maintain proper refrigeration. An inlet and
exhaust vent is required to insure adequate air flow.
The refrigerator is equipped with an inlet vent located
at the bottom front of the refrigerator. The installer is
required to provide the exhaust vent. The exhaust vent
must have a cross sectional area of 30 square inches
minimum. The exhaust vent is to be installed above the
top surface of the refrigerator so as not to trap hot air
generated by the cooling unit. The refrigerator is
equipped with a DC ventilation fan to assist the air flow
across the refrigerator's cooling system while operating
the refrigerator in the Gas mode.
Ventilation Fan
A thermostat controlled mechanical fan is used to
move air across the refrigerator's cooling system. The

The propane gas mode of operation is that of a sealed
combustion unit. A sealed combustion installation util-
izes a single fresh vent-air intake/exhaust assembly to
supply fresh air to the burner and to remove the prod-
ucts of combustion. This insures the products of com-
bustion are isolated from the living area of the vehicle.
The vent-air intake/exhaust assembly is routed through
the vehicle's outside wall and is connected to the
refrigerator's burner assembly and exhaust flue tube by
flexible piping. The vent-air intake/exhaust assembly
used for this installation has been certified for this
refrigerator and must not be modified.
thermostat is calibrated to activate the fan whenever
the vehicle's interior temperature reaches 85 degrees
or higher.
When leaving the vehicle unattended, it is advisable
to leave windows or roof exhaust vents open to main-
tain the vehicle's interior temperature below 85 de-
grees. This will allow the refrigerator to operate
efficiently, minimize fan operation, and limit current
draw from the battery.

Improper location and installation can cause injury or
property damage. This refrigerator and it's vents are
design certified by the American Gas Association and
the Canadian Gas Association. Any deviation or sub-
