Part 1 - General Safety Information
A. Boiler Protection Devices
The boiler is protected from malfunctioning by means of internal
checks performed by the electronic microprocessor PCB, which stops
the boiler from operating if necessary. In the event of the boiler being
shut o in this manner, a code appears on the display which refers to
the type of shut-o and the reason behind it.
There are two types of shut-o:
1. Blocking Error
A blocking error means the boiler will restart
automatically as soon as the problem which
caused the error clears or is removed; the error
is indicated by the « » symbol which
appears on the display followed by the error
code.
For example, if the boiler indicates a 110 error
code, the error will clear automatically when
the CH temperature decreases. The boiler will
restart and operate normally.
NOTE: Contact a qualied service technician if
the error continues to occur.
In the event of Error 108 - Shut-o due
to insucient water pressure inside the
heating circuit - Pressure can be increased
by lling the heating circuit. See lling and
purging procedures, this manual.

2. Lockout Error
A lockout error means the boiler does not return to operation after the
error condition goes away. The button must be pressed on the
control panel to restore boiler operation.
If the error condition occurs often contact a qualied service technician.
3. Malfunction Warning
This warning is shown by the display in the following format:
5 P1 = FIRST IGNITION ATTEMPT UNSUCCESSFUL
The rst part of the error code (e.g. 1 01) indicates the aected
operational assembly.
1 - Primary Circuit
2 - Domestic Hot Water Circuit
3 - Internal Electronic Part
4 - External Electronic Part
5 - Ignition and Detection
6 - Air inlet - ue gas outlet
7 - Multi-zone Heating
If Error 108 occurs frequently and system needs repeated relling, turn
the boiler o. Turn the external electric power to the OFF position. Shut
o the main gas valve. Contact a qualied service technician to check
for any leaks of water.
WARNING
Important
Contact a qualied service technician for assistance if a
Lockout Error occurs frequently. For safety reasons, the
boiler will permit a maximum of ve (5) resets in 15 minutes
(ve [5] presses of the RESET button). A sixth (6th) attempt
within this 15 minute period will lock out the boiler. The boiler
will only operate again after the electrical supply has been
disconnected and reconnected.
Repeated Lockout Error conditions could indicate a serious
error with the boiler or installation. Failure to contact a
qualied service technician to troubleshoot the error could
result in substantial property damage, serious personal
injury, or death.
