Installation Manual 18
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.
WARNING
!
Ignition and Start Up
NOTICE
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.
Refer to the “Display Codes” section of this manual.
Ignition and start up:
If the gas does not ignite in 30 seconds, the gas safety valve of the refrigerator automatically closes and the GAS light
flashes. To reset the controls, push the selector switch to the OFF position.
If the gas does not ignite after several attempts, refer to the “Fault Codes” section of this manual.
