Owner’s Manual 9
Automatic mode operation:
When the refrigerator is in AUTO mode, the electronic controls of the refrigerator automatically select and use the most efficient energy
source that is available for operation.
During operation, if a more efficient energy source becomes available, the electronic controls of the refrigerator automatically changes
from the current energy source to the more efficient energy source as follows:
- The first choice of operation is AC electric mode.
- If AC electric is not available to the refrigerator, if the AC electric is outside of the permitted operating range, or if the AC heater
does not operate; the electronic controls of the refrigerator automatically change to the second choice of operation.
- The second choice of operation is gas mode.
- The refrigerator attempts to operate the propane gas burner. If unable to establish and maintain a flame, a “no” FL” fault code
shows on the LCD. Refer to “Fault Codes” section of this manual.
- On 3-way models only, the electronic controls of the refrigerator automatically change to the third choice of operation.
- The third choice of operation is DC electric mode.
- If the DC heater does not operate; a “dc” HE” fault code shows on the LCD. Refer to “Fault Codes” section of this
manual.
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 the propane gas tank, the propane gas supply lines can have air in them. Due to the air in the
gas supply lines, the refrigerator 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 all of the gas valves are open.
- Push and release the POWER ON/OFF button [30] to turn on the refrigerator.
- Push and hold the MODE button [31] until the Manual mode gas indicator [284] is on.
- Push and release the TEMPERATURE SET button until the desired temperature setting shows.
- 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 sparks.
- After 30 seconds, if the Manual mode gas indicator remains on, it means that the refrigerator is operating on propane gas.
- 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.
- If the gas does not ignite within 30 seconds, the gas valve of the refrigerator will automatically close and a “no” “FL” fault code
will show in the LCD. To reset the controls, press and hold the POWER ON/OFF button for 1 second to turn the refrigerator
off, then press it again to restart the refrigerator and begin another 30 second trial for ignition.
- 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.
