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 for twenty-four hours continuously or longer should use the
C7012E,F Flame Detector with the R7847C Amplifier or the C7076A 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.
