c
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 or the C7061
Flame detector with the R7861 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.
f
When R7861 is used with EC7895, the application requires a step down transformer. See Fig. 14.
g
Use with RM7895A only.
