Installation Manual 11
- 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:
WARNING:
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.
Ignition and Start Up
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)
NOTE: 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.
If the gas does not ignite after several attempts, refer to the “Fault
Codes” section of this manual.
Set the controls to automatic mode operation:
- Push the ON / OFF button [30] to turn the refrigerator on.
- Push and hold the MODE button [31] until the letters “AU”
show in the center display [33] and then release.
- If 120 volts AC is available to the refrigerator:
- The letters “AU” and then “AC” show in the center
display.
- After ten seconds, the “AU” and then “AC” go off and
only a green power ON light remains.
- This means that the refrigerator is operating on AC
electric.
- If 120 volts AC is not available to the refrigerator:
- The letters “AU” and then “AC” show in the center
display.
- After five seconds, the “AU” and then “LP” show in the
center display.
- After ten seconds, the “AU” and the “LP” go off and only
a green power ON light remains.
- This means that the refrigerator is operating on propane
gas.
- If neither 120 volts AC nor propane gas is available to the
refrigerator:
- The fault codes “no” “AC” and then “no” “FL” show in the
center display and an audible alarm sounds.
