ture is repaired by a technician and he pushes
the RESET button on the display.
If the red ‘FAULT’ light is not illuminated, and
this message is displayed, then the return tem-
perature of the boiler is at or above 210 Deg. F.
The message will clear automatically when the
temperature drops below 194 Deg. F. During the
time that this message or lockout fault is dis-
played, the pump will be on as indicated on the
second line of the display.
Remedy:
1. Check circulator pump operation.
2. Assure that there is adequate flow through the
boiler by accessing the status menu and assur-
ing that there is less than a 50°F rise from the
return thermistor to the supply thermistor.
3. Check the direction of flow on boiler circulator.
(See Piping Details in Section 5 of this manual.)
4. Troubleshoot thermistor by following steps in

Fault Code F09
NO FLAME ON IGN
PUMP ON
F09
Description:
The boiler tried to ignite four times during one
heat call and failed ignition all four times. The
red light will display and the word LOCKOUT will
flash on the display. This code indicates a seri-
ous safety issue and the boiler will not restart
until the cause of no ignition is repaired by a
technician and he pushes the RESET button on
the display. During this lockout fault, the pump
will remain 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, check the spark electrode
for the proper .196” (5.0 mm ± 1mm) gap.
3. Remove any corrosion from the spark elec-
trode 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 boiler was firing 3
times during 1 demand call. The red light will
display and the word LOCKOUT will flash on the
display. This code indicates a serious safety
issue and the boiler will not restart until the
cause of the flame loss is determined by a tech-
nician and he pushes the RESET button on the
display. During this lockout fault, the pump will
be on as indicated on the second line of the dis-
play.
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 seconds after the boiler ignites
4. Check the FLAME signal on the status dis-
play. It should be above 1.0 when the boiler
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” sig-
nal is still less than 1.0, replace the flame
probe and spark igniter probe.
7. The flame signal should be steady after the
boiler has been firing for 1 minute and is nor-
