Installation and Owner’s Manual 26
- Make sure that the materials used for the gas supply line obey both the current ANSI A 119.2 (NFPA 1192) and CSA Z240
Standards on Recreational Vehicles. Norcold recommends the use of 3/8 inch copper tubing as the gas supply line and requires a
3/8 inch SAE (UNF 5/8-18) male fl are fi tting as the connection to the refrigerator.
- Put the propane gas supply line up through the fl oor of the enclosure.
- Make sure the hole through the fl oor 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 fl oor to prevent vibration
and 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 fi tting 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 electrically
conductive and can cause electrical shorts and in some cases, fi re.
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 Water
Column).
- If the pressure of the compressed air is more than 1/2 psig (14 inches Water Column), remove the gas supply line from the
bulkhead fi tting 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 of
the refrigerator before the test.
