IMPORTANT
A flame detection system is required for operation
and must be ordered separately. Select the
applicable flame signal amplifier and matching flame
detector from Table 4.
Table 4. Flame Detection Systems.
a
Flame Failure Response Time (FFRT) depends on selection of amplifier.
b
Circuitry tests all electronic components in flame detection system (amplifier and detector) 12 times a minute during burner
operation and shuts down burner if detection system fails.
c
Circuitry tests flame signal amplifier 12 times a minute during burner operation and shuts down burner if amplifier fails.
d
Use C7027, C7035 and C7044 Flame Detectors only on burners that cycle on-off at least once every twenty-four hours. Use
C7061A,M Ultraviolet Detector with R7861A Amplifier or C7076A Flame Detector with R7886A Amplifier as ultraviolet flame
detection system for appliances with burners that remain on continuously for twenty-four hours or longer.
e
R7847A,B Amplifiers with 0.8 second FFRT should NOT be used with C7012A,C Solid State Ultraviolet Detectors.
f
Order flame rod separately, see flame detector Instructions for holder.
