Dometic RM 4223 - Manual (Page 2)

1. GENERAL INSTRUCTIONS
This appliance is designed for storage of food and
storage of frozen food and making ice.
The refrigerators outlined herein have been design certi-
fied by A.G.A. under ANSI Z21.19 Refrigerator Standard
for installation in a mobile home or recreational vehicle
and are approved by the Canadian Gas Association. The
certifications are, however, contingent on the installation
being made in accordance with the following instructions
as applicable.
In the U.S.A., the installation must conform with:
1. National Fuel Gas Code ANSI Z223.1-(latest edition)
2. Manufactured Home Construction and Safety
Standard, Title 24 CFR, Part 3280
3. Recreational Vehicles ANSI A119.2-(latest edition).
The unit must be electrically grounded in accordance
with the National Electric Code ANSI/NFPA 70-(latest
edition) when installed if an external alternating current
electrical source is utilized.
4. Any applicable local code.
In Canada, the installation must conform with:
1. Current CGA B 149 Gas Installation Codes
2. Current CSA Standard Z 240.4 GAS-EQUIPPED
RECREATIONAL VEHICLES AND MOBILE
HOUSING
3. Any applicable local code
The unit must be electrically grounded in accordance
with the CANADIAN ELECTRICAL CODE C 22 Parts 1
and 2.
2. VENTILATION
The installation shall be made in such a manner as to
separate the combustion system from the living space of
the mobile home or recreational vehicle. Louver ope-
nings must have a minimum dimension of 1/4 inch for air
supply or venting of combustion products.
Proper installation requires one fresh air intake and one
upper exhaust vent. The ventilation kits shown in this
instruction manual have been certified for use with the
refrigerator model listed in the Table. For "Certified Vent
System Kits" see Section B. The ventilation kits must be
installed and used without modification. An opening
toward the outside at floor level in the refrigerator com-
partment must be provided for ventilation of heavier-
than-air fuel gases. The lower vent of the recommended
kits is provided with properly sized openings. The flow of
combustion and ventilation air must not be obstructed.
The lower side vent is fitted 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.
3. CERTIFIED INSTALLATION
Certified installations require one upper side vent and
one lower side vent.
For certified vent system kits, see Section B.
For further information, contact your dealer or distributor.
4. METHOD OF INSTALLATION
The methods of installation are shown in FIG. 1 & FIG.
1A. It is essential that all maximum or minimum dimen-
sions are strictly maintained as the performance of
the refrigerator is dependent on adequate flow of air over
the rear of the refrigerator.
NOTE: The upper vent should be centered over the
condenser coil at the back of the refrigerator.
