/ Solution
1. The ON/OFF power switch is set to
ON ( I ), and the power ON (green)
LED is not illuminated.
1.1 The power cord is not plugged into the
power receptacle.
Plug the power cord into the receptacle.
1.2 The disconnect power switch is not set to
ON or there is no power available to the
disconnect power switch box.
Turn on the power at the main power panel or
at the disconnect power switch box.
2. The power ON (green) and gas
pressure (yellow) LEDs are
flashing and the fault (red) LED
is illuminated.
2.1 The gas supply is turned OFF or not
connected to the power supply.
Check that the gas is turned on and is
connected to the power supply.
2.2 The incoming gas pressure is too low.
Set incoming gas pressure to 90-120 psig
(6.2-8.3 bar). Check that there are no leaks in
the gas supply line.
2.3 Output gas pressure is set too low for
selected mode.
Adjust gas pressure. See Section 4 for
pressure settings.
3. The power ON, low line voltage
(yellow), and fault (red) LEDs are
illuminated.
3.1 Line voltage is too low, too high, or a
phase (CE system only) is missing.
Have a qualified technician check the
incoming power.
4. The power ON (green),
temperatue (yellow) and fault
(red) LEDs are illuminated.
4.1 One of the internal thermostat switches
has opened due to overheating or
extremely low temperature.
Leave the power supply on to allow the fan to
cool the power supply (overheating). Move
the power supply to a warm location (extreme
cold).
Note: The fan turns on and off
automatically. The fan may not
be in operation even though
the power is ON ( I ).
