1. GENERAL INSTRUCTIONS
This appliance is designed for storage of foods and
storage of frozen foods 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 Stan-
dard, Title 24 CFR, Part 3280
3. Recreational Vehicles ANSI Al
19.2-(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 REC-
REATIONAL 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
separatethecombustion system from the living space of the
mobile home or recreational vehicle. Louveropeningsforair
supply or for venting of combustion products shall have a
minimum dimension of not less than 1/4 inch.
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
theoutsideatfloor level in the refrigeratorcompartment must
be provided forventilation of heavier-than-air fuel gases. The
lower vent of the recommended kits is provided with proper
size 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 roof 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 method of installation is shown in FIG. 1. It is essential
that all maximum or minimum dimensions are strictly main-
tained as the performanceof the refrigerator is dependent on
adequate flow of air over the rear of the refrigerator.

FOR YOUR SAFETY, when refueling, shut off all LP gas appliances which are vented to the outside.
Inanabsorptionrefrigeratorsystem,ammoniaisliquefiedin
the finned condenser coil at the top of the refrigerator. The
liquid ammonia then flows into the evaporator (inside the
freezer section) and is exposed to a circulating flow of
hydrogen gas, which causes the ammonia to evaporate,
creating a cold condition in the freezer.
