Installation Manual 18WARNING!Connect the Propane Gas ComponentsThis refrigerator operates on propane gas at a pressure of 11 inches Water Column Propane.Connect the propane gas supply system:Be very careful when working on or near the propane gas system.- Do not smoke, or use an open flame near the propane gas system.- Do not use an open flame to examine for leaks.- Do not connect the refrigerator to the propane gas tank without a pressure regulator between them.- To avoid a propane gas leak, always use two wrenches to tighten or loosen the propane gas supply line connections.- Leaking propane gas leak can ignite or explode and result in dangerous personal injury or death.Connect the gas supply line to the refrigerator:- Make sure that all tubing and fittings obey all local, state, and national codes about size and type.- Make sure that all flexible metal connectors obey the current CAN1-6.10 Standard.- Make sure that the materials used for the gas supply line obey both the current ANSI A 119.2 (NFPA 1192) and CSA Z240Standards on Recreational Vehicles. Norcold recommends the use of 3/8 inch copper tubing as the gas supply line and requires a3/8 inch SAE (UNF 5/8-18) male flare fitting as the connection to the refrigerator.- Put the propane gas supply line up through the floor of the enclosure.- Make sure the hole through the floor is large enough allow clearance for the gas supply line.- Put a weather resistant seal (grommet, sealant, etc.) around the gas supply line where it goes through the floor to prevent vibrationand abrasion.- To prevent vibration and abrasion, make sure that the gas supply line is not against anything in the enclosure.- Attach the gas supply line to the bulkhead fitting of the refrigerator.Examine the gas supply system for leaks:Do not allow the leak detecting solution to touch the electrical components. Many liquids are electricallyconductive and can cause electrical shorts and in some cases, fire.Use a leak detecting solution to examine the gas supply line and all propane gas connections for leaks.If you use compressed air for the test:- The pressure of the compressed air at the manual shut off valve of the refrigerator must not be more than 1/2 psig (14 inches WaterColumn).- If the pressure of the compressed air is more than 1/2 psig (14 inches Water Column), remove the gas supply line from thebulkhead fitting of the refrigerator before the test.- If the pressure of the compressed air is equal to or less than 1/2 psig (14 inches Water Column), close the manual shut off valve ofthe refrigerator before the test.WARNING!
