Norcoldrecommends the use of 3/8 inch copper tubing as the gassupply line and requires a 3/8 inch SAE (UNF 5/8-18) maleflare fitting as the connection to the refrigerator.- Put the propane gas supply line up through the floor of theenclosure.- Make sure the hole through the floor is large enough allowclearance for the gas supply line.- Put a weather resistant seal (grommet, sealant, etc.) aroundthe gas supply line where it goes through the floor to preventvibration and abrasion.- To prevent vibration and abrasion, make sure that the gassupply line is not against anything in the enclosure.- Attach the gas supply line to the bulkhead fitting of therefrigerator.Examine the gas supply system for leaks:WARNING: Do not allow the leak detecting solutionto touch the electrical components. Many liquids areelectrically conductive and can cause electrical shorts andin some cases, fire.Use a leak detecting solution to examine the gas supply line andall propane gas connections for leaks.If you use compressed air for the test:- The pressure of the compressed air at the manual shut offvalve of the refrigerator must not be more than 1/2 psig (14inches Water Column).- If the pressure of the compressed air is more than 1/2 psig(14 inches Water Column), remove the gas supply line fromthe bulkhead fitting of the refrigerator before the test.- If the pressure of the compressed air is equal to or less than1/2 psig (14 inches Water Column), close the manual shutoff valve of the refrigerator before the test.Ignition and Start UpBefore ignition or start up of the refrigerator:- Make sure the air flow in the lower intake vent, through therefrigerator coils and condenser, and out the upper exhaustvent is not blocked or decreased.- Make sure there are no combustible materials in or aroundthe refrigerator.Ignition and start up:(N64X, N64XXX, N64XIM, N64IMXX, N84X,N84XXX, N84XIM, N84IMXX)(See Art01018)NOTE: If the gas does not ignite in 30 seconds, the gas safetyvalve of the refrigerator automatically closes.
