This appliance is certified under the latest edition of ANSI Z21.19•CSA 1.4 Refrigerators using gas fuel.

The installation must conform with local codes, or in ab- sence of local codes, the following standards as appli- cable.

In the U.S. the installation must conform with:

1.National Fuel Gas Code, ANSI Z223.1/NFPA 54 (latest edition).

2.Recreational Vehicles Code, ANSI A119.2 (latest edition)

3.Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280.

If an external electrical source is utilized, the refrigera- tor, when installed, must be electrically grounded in ac- cordance with local codes or, in the absence of local codes, the National Electrical Code, ANSI/NFPA 70 - (lat- est edition).

In CANADA, the installation must conform with:

If an external electrical source is utilized, the refrigera- tor, when installed, must be electrically grounded in ac- cordance with local codes or, in the absence of local codes, the Canadian Electrical Code, CSA C22.1, Parts

Iand II - (latest edition).

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. Openings for air supply or for venting of combustion products shall have a minimum dimension of not less than 1/4 inch.

Proper installation requires one lower fresh air intake and one upper exhaust vent. The ventilation kits shown in this instruction manual have been certified for use with the refrigerator models listed in the Table.

For “Certified Vent System Kits” see page 14.

The ventilation kits must be installed and used without modification. An opening toward the outside at floor level in the refrigerator compartment must be provided for ventilation of heavier-than-air fuel gases. The lower vent of the recommended kits is provided with proper size openings. The flow of combustion and ventilating 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.

GAS CONNECTION

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 flare connection. All completed con- nections should be checked for leaks with soapy water.

! WARNING

DO NOT use a flame to check for gas leaks.

The gas supply system must incorporate a pressure regu- lator to maintain a supply pressure of not more than 11 inches water column.

When testing the gas supply system at test pressures in excess of 1/2 psi, the refrigerator and its individual shutoff valve must be disconnected from the gas supply piping system.

When testing the gas supply system at pressures less than or equal to 1/2 psi, the appliance must be isolated from the gas supply piping system by closing its indi- vidual manual shutoff valve.

In case detailed instructions on the installation and con- nection to the gas supply are required, contact your dealer or distributor.

ELECTRICAL CONNECTION

120 Volts AC Connection

The refrigerator is equipped with a three-prong (ground- ing) plug for your protection against shock hazards and should be plugged directly 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 and therefore recommended that the re- ceptacle be located to the left side of the refrigerator (viewed from the rear) and approximately 6 inches from the floor (see FIG. 3). This allows easy access through the vent door. The cord should be routed to avoid direct contact with the burner cover, flue cover or any other components that could damage the cord insulation.
