NOTE: DAMAGE TO THE Boiler CAUSED BY EXPOSURE TO
CORROSIVE VAPORS IS NOT COVERED BY WARRANTY. (Refer to
the limited warranty for complete terms and conditions.)
E. General Cautionary Statements
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.
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.
Figure 1 - Blocking
Error Example
NOTE: Contact a qualied service technician if the
error continues to occur.
In the event of Error 108 - Shut-o due to
insucient water pressure inside the heating
circuit - turn the boiler o. Turn the external
electric power to the OFF position. Shut o the
main gas valve and contact a qualied service
technician to check for any leaks of water.

O Error for Low
Water Pressure
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.
Figure 3 - Lockout Error Example
If the error condition occurs often contact a qualied service technician.
Important
Contact a qualied service technician for assistance if a Lockout Error
occurs frequently. Repeated Lockout Error conditions could indicate
a serious error with the boiler or installation. Failure to contact a
qualied service technician to troubleshoot the error could result in
substantial property damage, serious personal injury, or death.
If the boiler signals the error again after a reset, turn o the boiler.
Move the external electric switch to the OFF position. Close the gas
valve and contact a qualied service technician.
DO NOT attempt to repair or service this boiler. Contact a qualied
service technician if the boiler needs repair or maintenance. Ask your
gas supplier for a list of qualied service providers.
Ensure each zone valve connected to the boiler is open while
the boiler is operating. Doing so ensures proper heating system
operation.
DO NOT wipe the boiler or control panel with a wet cloth. Doing
so may result in an electric shock, substantial property damage,
premature boiler failure, severe personal injury, or death.
There are two types of shut-o:
Always be careful when opening a hot water faucet or draining water
from the boiler. Water temperature over 125
o
F can instantly cause
severe burns or death from scalds. Children, disabled, and elderly
are at the highest risk of being scalded. See Installation Manual
before setting temperature at boiler. Feel water before bathing or
showering!
