Ventilation is one of the requirements for proper cooling
unit operation. The installation should be made in such a man-
ner as to separate the combustion system from the living space
of the mobile home or recreational vehicle. Openings for air

and one
lower side vent.
The ventilation kits shown in this
manual have been certifi ed for use with the different models as
displayed in the “Certifi ed Vent System Kits” table
The ventilation kits must be installed and used without
modifi cation! An opening toward the outside at fl oor level
in the refrigerator compartment has be provided for ventila-
tion of heavier-than-air fuel gases. The lower vent of the
recommended kits is provided with proper size openings.
The fl ow of combustion and ventilating air must not be
obstructed.
The lower side vent is fi tted with a panel, which provides
an adequate access opening for ready serviceability of the
burner and control manifold of the refrigerator. This should
be centered on the back of the refrigerator.

are located on the top, back, bottom, sides and doors.
If the surface is punctured, loss of insulation will oc-

For a proper installation, follow these instructions:
Make sure the fl oor is solid and level.
The refrigerator must be level and installed in a substantial
enclosure.
Do not install the appliance directly on carpeting. Carpet-

beneath the appliance, which extends at least full width and
depth of the appliance.

outside of the vehicle, the installer will have to supply the extra
length of hose.
Hook up to the gas supply line is accomplished at the manual
gas valve, which is furnished with a 3/8” SAE (UNF 5/8” -18)
male fl are connection. All completed connections should be ex-
amined for leaks using a solution of liquid detergent and water.
Be very careful when working on or near the gas sys-
tem. Do not use an open fl ame to check for gas leaks!
The gas supply system must incorporate a pressure regulator
to maintain a supply pressure of not more than 11 inches water
column. When testing the gas supply system at test pressures:
> 1/2 psi
- the refrigerator and its individual shutoff valve
must be disconnected from the gas supply piping system.
≤ 1/2 psi
- the appliance must be isolated from the gas
off valve.
If detailed instructions on the installation and connection to
the gas supply are required, please contact your dealer or
distributor.

Testing LP gas safety shut off
The gas safety shut off must be tested after the refrigerator is
connected to LP gas supply.
RM2354-2454-2554-2662-2663-2862-3862 &NDR1062
To test the gas safety shut off, follow these steps:
Check that the gas fl ame is lit and the GAS mode
indicator lamp is on.
Close the manual gas shutoff valve at the back of the
refrigerator.
Wait for approx. 6 minutes. The CHECK indicator
lamp should be lit and the GAS mode indicator lamp
Remove the protection cover.
Open the manual gas shutoff valve. Do not change
any button positions on the control panel.
Apply a non corrosive commercial bubble solution
to the burner jet orifi ce. No bubbles should appear at
the opening of the burner jet orifi ce. The presence of
bubbles indicates a defective gas safety shutoff, and
If no bubbles are present at the burner jet orifi ce,
rinse it with fresh water. Be careful not to damage
the burner jet orifi ce.
Put back the cover.
Press the ON/OFF button once to turn the refrigera-
tor off and then press it again to turn the it back on.
Normal operation of the burner should return.
Allow the burner to operate for a minimum of fi ve
minutes.

The refrigerator is equipped with a grounded three-prong plug
for protection against shock hazards. It should be plugged di-
rectly into a properly grounded three-prong receptacle. Do not
cut or remove the grounding prong from this plug!
The free length of the cord is 2 feet. It should be routed to
avoid direct contact with the burner cover, fl ue cover or any
other components that could damage the cord insulation.
To allow easy access through the vent door, it is recommended
that the receptacle is placed:

chassis or vehicle frame as one of the conductors. Connect two
wires at the refrigerator and route to the DC supply. Ensure the
connections are clean, tight and free from corrosion.
The distance the current must travel from the battery to the
refrigerator dictates the AWG wire size to be used. Should the
wire be too small for the distance, a voltage drop will result
causing a decreased cooling capacity.
