Checking cut-off pressure
After the installation is completed, continue with the following
procedures:
1. Slowly close manual main valve with the burner in
operation. Shut down should occur when the pressure
drops below the set point and the alarm
(if connected)

be energized.

rise and exceed the set point value, the burner should
start
up and the alarm turn off after the reset button is
depressed.
