Refer to Table 6 for the minimum acceptable flame
currents for the amplifiers and associated flame safeguard
controls.
With the flame detector installed and the burner running,
adjust the sighting position of the detector
for optimum flame
signal.
The

7800 SERIES flame safeguard controls respectively, have a
dc voltage flame signal output.
Most existing Honeywell flame safeguard controls have a
