Ignition and Start Up
- 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 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 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 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 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 electrically
conductive 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 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 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 of
the refrigerator before the test.
Before ignition or start up of the refrigerator:
- Make sure the air flow in the lower intake vent, through the refrigerator coils and condenser, and out the upper exhaust vent is not
blocked or decreased.
- Make sure there are no combustible materials in or around the refrigerator.
Ignition and start up: (N64X, N64XXX, N64XIM, N64IMXX, N84X, N84XXX, N84XIM, N84IMXX)
(See Art01018)
If the gas does not ignite in 30 seconds, the gas safety valve of the refrigerator automatically closes. The controls
either select a different energy source or “no” “FL” appears in the center display and you will hear an alarm sound. This
means that the gas did not ignite.
