NOTE
•
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.
