TROUBLESHOOTING
PART 12: TROUBLESHOOTING
(CONTINUED)
will be on as indicated on the second line of the display
Remedy:
1. Watch the igniter through the observation window provided.
2. If there is no spark, for natural gas units check the spark electrode for the proper gap. Use 2
quarters together as a gauge to hold ignitor against to check gap distance. (See Fig. 12-1 in
manual)
3. Remove any corrosion from the spark electrode and flame rectifier probe.
4. If there is a spark but no flame, check the gas supply to the boiler.
5. If there is a flame, check the flame sensor.
6. Check any flue blockage or condensate blocks.
Fault Code F10
FLAME LOSS
F10
Description:
The flame was lost while the unit was lit 3 times during 1 demand call. This code indicates a serious
safety issue and the unit will not restart until the cause of the flame loss is determined by a techni-
cian and he pushes the RESET button on the display. The red light on the display illuminating and
the word LOCKOUT flashing on the display. During this lockout fault, the pump will be on as indi-
cated on the second line of the display.
Remedy:
1. Monitor the gas pressure to the unit while in operation.
2. Assure that the flame is stable when lit.
3. Check to see if the display readout changes from “GAS VALVE ON” to “RUN” within a few sec-
onds after the boiler ignites
4. Check the FLAME signal on the status display. It should be above 1.0 when the unit is firing.
5. If the signal reads less than 1 microampere, clean the flame rectifier and spark probe.
6. If the problem persists and the ‘FLAME” signal is still less than 1.0, replace the flame probe and
spark igniter probe.
7. The flame signal should be steady after the unit has been firing for 1 minute and is normally
at 5.0 to 9.0. If the flame signal is not steady, disassemble the burner door and check the burn-
er and its sealing gaskets.

NOTE: If receiving an F09 fault code, check the gap spacing between points on the electrode.
