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; the C7061 Flame Detector with the R7861 Amplifier, or the C7076 Flame
Detector with the R7886A Amplifier as the ultraviolet flame detection system.
c
Circuitry tests the flame signal amplifier at least 12 times a minute during burner operation and shuts down the boiler if the
amplifier fails.
d
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.
NOTE: R7847C Series 4 or greater, pulse the shutter when the flame signal of 1.5 is sensed. Display readings of 0.7 to
2.4Vdc are common.
