LP-314 REV. 3.24.14

during any one of these three ignition trials, normal operation will resume. If the burner lights, and goes off in about 4 seconds, check
the polarity of the wiring. See Electrical Connection Section in Part 7.

If the burner does not light after the third ignition trial, the control will enter a lockout state. This lockout indicates that a problem exists
with the appliance, the controls, or the gas supply. Under such circumstances, a qualified service technician should be contacted
immediately to properly service the appliance and correct the problem. If a technician is not available, pressing RESET once will
remove the lockout state so additional trials for ignition can be performed.

PART 12 - TROUBLESHOOTING

A. APPLIANCE ERROR CODE

If any of the sensors detect an abnormal condition or an internal component fails during the operation of the appliance, 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.

However, it may also be the result of a condition that the controller has evaluated as not safe to restart the appliance. In this case, the
boiler control will be locked out, the red FAULT light will be lit steadily,

and the message “LOCKOUT” will be displayed on the readout

on the lower line. The appliance will not start until a qualified technician has repaired the fault 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
that more serious problems will occur soon.

B. APPLIANCE ERROR

When an error condition occurs, the controller will display a description and code on the display readout. These error messages and
their recommended corrective actions are described in Section D, Appliance Control Fault Codes.

C. APPLIANCE FAULT

1. When a fault condition occurs, the controller will illuminate the red FAULT light and display a fault message in the display. The alarm
output will also be activated. Most fault conditions also cause the CH pump to run in an attempt to cool the appliance.

2. Note the fault message that is displayed and refer to the Fault Code section for an explanation of the fault 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 recurrence of the fault message.

D. APPLIANCE CONTROL FAULT CODES

When servicing or replacing any components of this appliance, be certain that:

The gas is off.

All electrical power is disconnected.

When servicing or replacing components that are in direct contact with this appliance, be certain that:

There is no pressure in the appliance. (Pull the release on the relief valve to relieve pressure.)

Appliance water is not hot.

Electrical power is disconnected.

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.
