Part 11 - Troubleshooting
A. Boiler Error and Fault Codes
If any of the sensors detect an abnormal condition, or an internal
component fails during the operation of the boiler, the display
may show an error message and error code. This message and
code may be the result of a temporary condition, in which case
the display will revert to its normal readout when the condition
is corrected, or it may be a condition that the controller has
evaluated as not safe to restart the boiler. In this case, the boiler
control will be locked out, the red FAULT light will be lit, and the
message “LOCKOUT” will be displayed on the readout in the
lower line.
The boiler will not start until a qualied technician has repaired
the boiler and pressed the RESET button for more than 1 second.
If there is an error message displayed on the readout, and the
message “LOCKOUT” is not displayed and the FAULT light is not
lit, then the message is the result of a temporary condition and
will disappear when the problem corrects itself.
IMPORTANT NOTE: If you see error messages on your display
readout, call a technician immediately, since the message may
indicate a more serious problem will occur soon.
B. Boiler Error
The controller will display an error code and message when
an error condition occurs. These error codes, descriptions, and
recommended corrective actions are described in Section D.
C. Boiler Fault
1. The controller will illuminate the red “FAULT” indication light
and display a fault code and message when a fault condition
occurs. The alarm output will also activate. Most fault conditions
cause the CH pump to run in an attempt to cool the boiler.
2. Note the displayed fault code and refer to Section D for an
explanation of the message along with several suggestions for
corrective actions.
3. Press RESET to clear the fault and resume operation. Be sure
to observe the operation of the unit for a period of time to assure
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN
SUBMERGED IN WATER. Immediately call a qualied service
technician. The appliance MUST BE replaced if it has been
submerged. Attempting to operate an appliance that has been
submerged could create numerous harmful conditions, such as
a potential gas leakage causing a re and/or explosion, or the
release of mold, bacteria, or other harmful particulates into the
air. Operating a previously submerged appliance could result in
property damage, severe personal injury, or death.
NOTE: Appliance damage due to ood or submersion is
considered an Act of God, and IS NOT covered under product
warranty.
When servicing or replacing components that are in direct
contact with 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 disconnected.
• The gas is shut o.
Failure to make these checks could result in substantial property
damage, serious personal injury, or death.
Label all wires prior to disconnecting them when servicing
the boiler. Wiring errors can cause improper and dangerous
operation. Failure to follow these instructions may result in
property damage or personal injury.
If overheating occurs or the gas supply fails to shut o, do not
turn o electrical power to the circulating pump. This may
aggravate the problem and increase the likelihood of boiler
damage. Instead, shut o the gas supply to the boiler at the gas
service valve. Failure to do so may result in property damage,
personal injury, or death.
NOTE: If system return temperatures are maintained below the
dew point, condensation will form on the inside of the boiler
cabinet and cause some internal sheet metal components to
rust.
