The C7012A,C, C7027, C7035 and C7044 Flame Detectors should be used only on burners that cycle on-off at least
once every twenty-four hours. Appliances with burners that remain on continuously for twenty-four hours or longer
should use the C7012E,F Flame Detector with the R7847C Amplifier or the C7076A,D Flame Detector with the
R7886A Amplifier as the ultraviolet flame detection system.
d
Circuitry tests the flame signal amplifier at least 12 times a minute during burner operation and shuts down the burner
if the amplifier fails.
e
Circuitry tests all electronic components in the flame detection system (amplifier and detector) 12 times a minute
during burner operation and shuts down the burner if the detection system fails.
