TROUBLESHOOTING
9. Boiler holds at ignition speed for 10 seconds before
modulation begin.
10. Demand is met and removed.
11. Gas valve closes, Fan returns to ignition speed.
12. 10 second post purge period.
13. Pump remain energized for pump post purge period.
14. Full unit standby
WARNING WARNING
When servicing or replacing any components of this
boiler be certain that:
• The gas is off.
• All electrical power is disconnected.
Do not use this appliance if any part has been under
water. Improper or dangerous operation may result.
Contact a qualified service technician immediately to
inspect the boiler and to repair or replace any part of
the boiler which has been under water.
DANGER
When servicing or replacing components that are in
direct contact with the boiler water, be certain that:
• There is no pressure in the boiler. (Pull the release
on the relief valve. Do not depend on the pressure
gauge reading).
• The boiler water is not hot.
• The electrical power is off.
CAUTION
CAUTION
If overheating occurs or the gas supply fails to shut
off, do not turn off electrical power to the circulating
pump. This may aggravate the problem and increase
the likelihood of boiler damage. Instead, shut off the
gas supply to the boiler at the gas service valve.
Label all wires prior to disconnection when servicing
controls. Wiring errors may cause improper and dangerous
operation. Verify proper operation after servicing.

Error
Number
Error Display Corrective Action
0 E2PROM_READ_ERROR Internal Software error. Replace control.
1 IGNIT_ERROR
Three unsuccessful ignition attempts in a row.
– Check incoming voltage for a hot/neutral reverse (reversed polarity) condition.
– Check for spark by ear. Also check for 120V across the blue and brown control
output wire to the spark module. If not spark is present but voltage is. Replace
module. If no voltage is present check parameter 2126. Should be set to 9. If
setting is correct, replace control.
– Remove flame sensor and check for white build-up. Clean sensor, re-install and
attempt ignition. If ignition still fails perform other actions listed here. Replace
sensor. If sensor appears cracked or bent, replace sensor.
– Confirm fuel pressure at the valve inlet when the valve is open. Low gas pressure
can cause ignition failures. High gas pressure can cause the valve to not operate
and or damage the valve.
2 GV_RELAY_ERROR Failure detected in the Gas Valve Relay. Replace Control
3 SAFETY_RELAY_ERROR Failure detected in the safety relay. Replace Control.
4 BLOCKING_TOO_LONG
Blocking error present for more than 20 hours.
– Go to parameter 1052 for last blocking error code. Correct cause.
5 FAN_ERROR_NOT_RUNNING
Fan is not running for more than 60 secs.
– Check fan condition by disconnecting the 5 pin control plug on the blower. Fan
should ramp to full power when the unit is turned on.
– If fan does not power on, check for 120 volts across the brown and blue wires in
the three pin connector. If voltage is present, replace blower.
– If fan powers on check for continuity through blower control harness, 5 pin
connector to J4 connector on control board. If continuity is found replace
control. If no continuity is found, replace harness.
6 FAN_ERROR_TOO_SLOW
Fan runs to slow for more than 60 seconds
– Check voltage to the blower. A low voltage can cause the blower to run at the
incorrect speed due to lack of power. Replace blower if voltage is correct.
– Check for continuity through blower control harness, 5 pin connector to J4
connector on control board. If continuity is not found, replace harness.
– Replace control if other actions do not correct issue.
