Series Condensing Boiler Combi Manual
IMPORTANT
•
On initial startup of the system, it is necessary to put the boiler into an air purge process to
remove all air from the system piping and boiler. The boiler will not immediately fire up
and begin operation. The boiler will go into an automatic de
-
aeration program that is
approximately 7 minutes in duration.
•
It can take up to a week
before all the air has disappeared from a newly
-
filled and
pressurized installation. During the first week of operation, noises can be heard which
indicate the presence of air. The automatic air vent in the boiler and air separator in the
heating system will remove the air, which means the water pressure will reduce some
during this period; therefore, additional water is necessary to maintain proper pressure in
the heating system. Water pressure needed for operation:
−
The boiler is in normal operation between 14 PSI and 43.5 PSI.
−
Below 10.1 PSI, the boiler will have an error code (Fault 108 on the display) and be
blocked from operation. Increasing the heating system water pressure will be necessary
for operation.
−
Between 10 PSI and 14 PSI, operation will be limited to 80% (Alert Warning 1P4 will
appear on the display).
−
Above 43.5 PSI, the boiler will have an error code (Fault 109 on the display) and be
blocked from operation as the pressure is too high.
−
The maximum pressure permitted inside the heat exchanger is 45 PSI.
−
The pressure relief valve supplied with the boiler is rated to 30 PSI.
