Automatic Mode Operation; Removing Air From The Propane Gas Supply Lines - Norcold 121X series Owner's Manual

The MODE button [31] controls the operation mode of the refrigerator:
- Push and hold the MODE button and each of the operating modes of the refrigerator show one at a time in the center display.
- There is one automatic mode of operation and two manual modes of operation.
- When the mode of operation that you wish shows in the center display, release the MODE button.
NOTE: If you should forget in what mode your refrigerator is operating, push and release the MODE button to show the
current mode of operation in the center display for 10 seconds.

Automatic mode operation:

When the refrigerator is in AUTO mode, it automatically uses the most efficient energy source that is available for operation. During
operation, if a more efficient energy source becomes available, the refrigerator controls change from the current energy source to the
more efficient energy source as follows:
- The first choice is AC operation if 120 volts AC is available to the refrigerator.
- The second choice is propane gas operation if 120 volts AC is not available to the refrigerator.

Removing air from the propane gas supply lines:

For safety reasons, the burner is made to ignite on propane gas within a specified amount of time. When starting the refrigerator for
the first time, after storage, or after replacing propane gas tank, the propane gas supply lines can have air in them. Due to the air in the
gas supply lines, the burner may not ignite on propane gas within the specified amount of time.
To remove the air from the propane gas supply lines:
- Make sure that valve of the propane gas tanks(s) is open.
- Push the ON / OFF button to turn the refrigerator on.
- Push and hold the MODE button until the letters "LP" show in the center display.
- This means that the refrigerator is operating on propane gas.
- If the air in the propane gas supply lines prevents the burner from ignition on propane gas, the fault codes "no" and then "FL"
will appear in the center display and you will hear an alarm sound.
- Push and hold the ON / OFF button for one second and then release to silence the alarm.
- Push the ON / OFF button to turn the refrigerator on.
- The refrigerator will start a 30 second trial for ignition.
- During the 30 second trial for ignition, the refrigerator controls open the gas safety valve and the igniter makes sparks.
- When no fault code shows and only the power indicator remains, this means that the refrigerator is operating on propane gas in the
manual mode.
- At this time, all of the air is removed from the propane gas supply lines and you may select AUTO mode of operation if you
wish.
- Depending on how much air may be in the propane gas supply lines, you may need to repeat the 30 second trial for ignition two or
three times.
- If the burner does not ignite on propane gas after two or three attempts, stop and consult your local dealer or an authorized
Norcold Service Center.
