V. SAFETY CHECK
A. Check for gas leaks:
Using soap solution, check for gas leaks from meter to gas
valve including all pipes and fittings and gas valve
connections. Use liquid soap solution for all gas testing.
DO NOT use open flame.
B. Thermostat Test:
Set thermostat setting to low enough to end call for heat.
Gas valve should close and burner should stop firing.
Blower and circulator pump should go into a post purge,
then shut off.
A. LOCKOUT ERRORS: Indicated by an "A" in the mode display. The reset button must be pressed to clear the error
and retry operation. The temperature display shows the error code.

INDICATION
Ignition Failure - 3 unsuccessful
ignition attempts in a row.
Flame Failure - 3 losses of flame
signal during one demand.
Water High Limit Open
Control Failure
Flame Detected at Wrong Time
Fan Failure - RPM error
C. Control Safety Shutdown test:
With the burner firing, disconnect the spark cable from the
spark ignitor. Gas valve should close and burner should
stop firing. The boiler will try for ignition three times after
this, then should lock out with an "A 01" error shown on
the display. Reconnect the spark cable to the spark
ignitor, and press the "Reset" button to return to normal
operation.
VI. DIAGNOSTIC ERROR CODES
WARNING: Only a trained, experienced service technician
should perform troubleshooting. Turn off all electric power to
the boiler before service.
Check for steady sparking at electrodes. If spark not
steady - check spark gap to be 3.2mm (.125"), clean or
replace spark ignitor, check power supply voltage and
grounding. If spark is steady - check for proper gas sup-
ply pressure. Check combustion, if able to ignite, or
replace gas valve.
Check for proper combustion, at both max. and min.
input firing rates. If combustion is within the range
specified on page 37, clean or replace spark ignitor,
check power supply voltage and grounding.
Check to see if the water outlet temperature reaches
95°C (203°F). If it does, replace the water outlet 12k ohm
sensor. If it does not, replace the water high limit switch.
Replace control board. Make sure the proper boiler
model selection and confirmation code is entered.
See Table 5 on page 33.
If a flame is still observed after a call for heat is stopped,
replace the gas valve. If the burner seems to be shutting
down properly, replace the spark ignitor.
Check wire harness connections going to the blower.
Replace blower.
