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 qualified 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 correct operation and no reoccurrence of fault
message.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN
SUBMERGED IN WATER.
Immediately call a qualified 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 fire 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 flood 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 off.
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 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. 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.
