Start Up Instructions - Auto Mode
1. Move thermostat to COLDEST position. Set
AUTO-GAS switch to AUTO.
2. If 120 volts is active, Mode Control panel will
display AC, indicating refrigerator is operating
in 120 volt AC mode.
3. If 120 volts AC is inactive (power failure, dis-
connected, etc.), Mode Control panel will dis-
play LP, indicating refrigerator has automat-
ically switched to LP gas mode.
4. If Mode Control panel displays LP and a red X
continuously, the refrigerator has failed to ignite
burner on gas mode. Restart gas operation by
moving AUTO-GAS switch to the center posi-
tion and back to AUTO (See steps 3, 4, and 5
under Gas Mode.). Note: Unit operation will
automatically return to AC when 120 volts AC is
restored, even if the unit is locked out on gas
operation.

mid setting.
Start Up Instructions - Gas Mode
1. Move thermostat to COLDEST. Set AUTO-GAS
switch to GAS.
2. Mode Control panel will display LP, indicating
LP gas mode (If LP is not displayed, check for
loss of DC supply voltage.). Initially, the red X
will be displayed for about 2 seconds; after
which, sparking will start at the burner and the
red X goes off.
3. After 10 seconds, the burner should be ignited
and operating normally.
4. On the initial refrigerator start-up, it may take
longer than 10 seconds to allow air to be
purged from the gas line. If gas does not ig-
nite within 20 seconds, valve will automat-
ically shut off and the red X will be displayed
at the CHECK position.
5. To restart when the X is displayed, move
AUTO - GAS switch to the center position then
return switch to the GAS position.
NOTE: If the gas does not ignite after sev-
eral attempts, contact your dealer or a Nor-
cold authorized service center. .
