General Information
This refrigerator is not intended to be operated as

!
a free-standing refrigerator (i.e. the products of
ATTENTION
combustion must be completely isolated from the
living area) or installed in such a way as to conflict
with these installation instructions. Unapproved in-
stallations could result in safety risks or performance
problems.
Description and Operation
The model 3163 is designed for built-in installation and operates on propane
gas, 120 volts AC, or 12 volts DC.
The propane gas mode of operation is that of a sealed combustion unit. A sealed
combustion installation utilizes a single fresh vent-air intake/exhaust assembly
to supply fresh air to the burner and to remove the products of combustion.
This insures the products of combustion 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.
