Notes
•
The appliance is equipped with an electronic boiler controller, which ignites the
burner and continuously monitors the flame during each request for heat from the
heating or from the hot water supply.
•
The circulation pump starts running in response to every request for heat. The pump
continues running for 1 minute after heating. This post purge period can be changed
if desired (See § 10.3).
•
The pump runs automatically for 10 seconds every 24 hours in order to prevent
seizing. This will occur at the the time of the last request for heat. To change this time
the room thermostat should be turned up briefly at the desired time.
•
The pump does not run during DHW operation.
