The front of the combustion safeguard has two
test jacks marked + and - for flame monitoring,
(see Fig. 3.15). To access the test jacks remove
the combustion safeguard cover by turning the
center screw counterclockwise. A standard
voltmeter is required to monitor the flame signal
strength. The combustion safeguard will output a
0-15VDC signal from the test jacks. The
minimum required flame signal for operation of
the burner is 6 VDC.
