Gas Connection
The refrigerators are designed to operate on pro- pane 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 local, state, and national codes governing type and size. These components should also comply with NFPA 501C. Flexible metal connectors must comply with the current CAN
Route the gas supply piping to limit vibration and abrasion. The gas supply piping should enter the re- frigerator enclosure near the gas connection at the rear of the refrigerator. The hole through which the gas piping enters should be of sufficient size (ap- proximately 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 ma- nipulating the gas inlet fitting. Failure to use two wrenches can over stress the pip- ing and create gas leaks.

The gas supply is connected to the refrigerator at the inlet to the manual gas valve located at the bot- tom rear of the refrigerator. Access to this area is obtained through the vehicle’s lower vent door. Care must be taken when connecting the gas piping to the refrigerator to insure the fittings are secure.
