Refrigerator Ventilation Requirements
WARNING
ventilation or partial blockage of refrigerator’s flue can result in increased carbon monoxide emissions when operating in the gas mode. To prevent emission of hazardous levels of carbon monoxide, installation must assure complete isolation of the living space of mobile home or R.V. from refrigerator’s combustion system. Follow Norcold’s Ventilation and Installation recommendations explicitly.
Venting is required in an R.V. refrigerator application to remove products of combustion, to isolate the living space of the vehicle from the refrigerator’s combustion system, to remove excess heat from refrigerator’s cooling system generator area, and to remove heat that is extracted from the refrigerator cabinet.
Certified installation requires that one intake vent and one exhaust vent be used. Refer to Table 1 on page 4. To insure adequate refrigerator performance, a

Gas Supply and Connection

This refrigerator is designed to operate on propane gas at a supply pressure of 11 inches water column. A pressure regulator is required between the refrigerator and the main gas tank.
Do not connect the refrigerator
directly to the main propane tank without a pressure regulator.
Use supply piping and fittings that comply with loc al, st ate, and national codes gover ning type and s ize. These components should also comply with NFPA 501C. Flexible metal connectors must comply with current CAN1-6.10 Standard. To prevent gas pressure loss to refrigerator, the propane should be supplied by 3/8 inch diameter copper piping. The gas supply piping is connec ted to refrigerator by means of a 3/8 inch SAE (UNF 5/8-18) male flare connection.

Page 8
Route the gas supply piping to limit the possibility of vibration and abrasion. The gas supply piping should enter the refrigerator enclosure near the gas connection at the rear of the refrigerator. The hole through which the gas piping enters should be of sufficient size (approximately 1/2 inch diameter) to provide adequate clearance for the piping. Once the gas piping is in place, apply a sealant around the piping at its point of entry to minimize abrasion and vibration, and to serve as a barrier to external moisture.
CAUTION:
Use two wrenches when manipulating the gas inlet fitting. Failure to use two wrenches can
over stress the tubing and create gas leaks.

The distance the current travels from the battery to the refrigerator dictates the wire size. Undersized wire can result in a voltage drop, which will affec t the wattage output of the DC heater and result in reduced refrigerator performance. Norcold recommends the installation of a fuse in the supply wiring between the battery and the refrigerator. For optimum protection, install the fuse as close to the battery as possible.
WARNING
A circuit overload can result in an electrical fire when undersized wires or improperly sized
fuses are used. To prevent a possible electrical fire, follow ANSI A119.2 Standards , Norcold’s wire and fuse specifications, or applicable state and local codes.
