On initial startup of the system, it is necessary to manually run the pumps from the service
page to remove all air from the system piping and boiler. Failure to properly deaerate the
boiler and system may result in damage to the boiler, which is not covered by the boiler
warranty.
•
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 20 - 70 PSI.
−
Below 12 PSI and above 87 PSI, the boiler will have error codes (117 or 118 error code
will be present on the controller display) and will not operate. Increasing the heating
system water pressure is necessary for operation.
−
Below 12 PSI, error code 117 will be present on the controller display.
−
Above 87 PSI, error code 118 will be present on the controller display.
−
The maximum pressure permitted inside the heat exchanger is 160 PSI.
−
The pressure relief valve supplied with the boiler is rated to 75 PSI.
