Code
Description of
the Fault
Corrective Action
2 No flame at start-up
A flame failure occurred during light off.
1. Check the wiring of the ignition transformer, pilot
valve, and main valve(s).
2. Ensure manual shutoff valves on the pilot gas line
and main gas line are open.
3. Check the fuel / air ratio at light off.
4. Check the flame detector signal in the presence of a
known flame source. Replace the flame detector if it
does not produce the anticipated signal.
3 Air pressure switch open
The air pressure switch connected to terminal X3-02.1 is
open, causing a fault. Ensure the setpoint of the switch
is set to an appropriate value. Check the wiring of the air
pressure switch. If no air pressure switch is being used,
place a jumper from terminal X2-01.3 to X3-02.1.
4 Extraneous light
An extraneous light (flame signal present when there
should be none) fault occurred.
1. Ensure that the source of light is not a flame. If it is,
take corrective action immediately.
2. Ambient light can cause an extraneous light fault.
Ensure the flame scanner is viewing a dark area.
3. UV scanners typically fail on, giving a false flame
signal. Remove the UV scanner and cover the bulb to
ensure it is not seeing any light. Look inside the bulb
and see if any purple arcs of electricity are occurring
between the electrodes in the bulb. If there are, replace
the UV scanner.
5 Air pressure switch closed
The air pressure switch connected to terminal X3-02.1 is
closed before the blower output is energized in phase
22, causing a fault. Ensure the setpoint of the switch is
set to an appropriate value. Check the wiring of the air
pressure switch. If no air pressure switch is being used,
place a jumper from terminal X2-01.3 to X3-02.1.
