Ventilation
The installation shall be made in such a manner as to separate the combustion system
from the living space of the recreational vehicle. Openings for air supply or for
venting
of
combustion products shall have a minimum dimension of not less than
l/4 inch.
Approved installation requires one lower fresh air intake and one upper exhaust
vent. The accessory ventilation kits shown in these instructions have been tested
and approved for use with the refrigerator models identified. Their use is recommen
ded, and when employed, the ventilation kits must be installed and used without
modification,
An opening to the outside at floor level of the refrigerator compartment must be
provided for ventilation of heavier-than-air fuel gases, The lower vent in the
Dometic kits is provided with proper size openings.
Gas connect ion
Hook-up to the gas supply line is accomplished at the manual gas valve, which is
furnished with a 3/8” (SAE) male flare connection. All completed connections should
be checked for leaks with soapy water.
CAUTION: When connecting the gas line to the gas valve on the gas/e1 equipment at
the rear of the refrigerator, use a back-up wrench to prevent undue
rotation of the gas
c o c k ,
For hook-up and servicing purpose the
lower
vent is constructed as a lift out panel.
The gas supply system must incorporate a pressure regulator to maintain a supply
pressure of not more nor less than 11 inches water gage.
Electrical connections
110 V A.C.
The 110 V electric cord should be plugged into an approved receptacle in the
refrigerator compartment. The cord should be routed to avoid coming in contact witn
the burner cover, flue cover or other hot components.
12 V D.C.
On “Tri-Power” units there is an additional terminal block marked “12 V”. The refri-
gerator must be connected
to
the battery circuit with two wires of adequate capacity
to avoid voltage drop.
Do not use the body or chassis as a substitute for either of these wires (possibly
only in motor homes). No other electrical equipment or lighting should be connected
to the refrigerator circuit.
When estimating length and
area
of conductor cable, see table, page 6.
CAUTION :
Do not operate the refrigerator on 12 Volt when the vehicle is parked. You will run
the battery dead in a rather short time.
If possible the installation of a 12 Volt operated refrigerator should be
c o m p l e t e d
with a relay mounted either in the car or in the vehicle (see diagram). This relay
will automatically cut out the refrigerator when the car motor is stopped.
