Ignition and start up:
(N62X, N62XX, N82X, and N82XXX models)
(See Art01019)
NOTE: If the gas does not ignite in 30 seconds, the gas safety
valve of the refrigerator automatically closes and the
controls either select a different energy source and “F”
appears in the center display or the controls change to
Stand By Mode.
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, N64XIMXX, N84X,
N84XXX, N84XIM, and N84XIMXX models)
(See Art01018)
NOTE: If the gas does not ignite in 30 seconds, the gas safety
valve of the refrigerator automatically closes and the
controls either select a different energy source and
“no” “FL” appears in the center display or the controls
change to Stand By Mode.
In Stand By Mode, an audible alarm starts and the code “no”
“FL” appears in the center display. 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.
Automatic Mode Operation:
1. Push the ON/OFF button [1] to start 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.
