aOrder flame rod separately; see holder instructions. b Use only Honeywell Photocell part number 38316.

c Dynamic Self-Check ultraviolet amplifiers should be used only on burners that cycle on-off at least once every 24 hours. Appliances with burners that remain on continuously for 24 hours or longer should use C7061A Flame Detector with R7861A

Amplifier.

d C7027, C7035 and C7044 Flame Detectors should be used only on burners that cycle on-off at least once every 24 hours. Appliances with burners that remain on continuously for 24 hours or longer should use C7061A Flame Detector with R7861A

Amplifier as ultraviolet flame detection system.

e Circuitry tests the flame signal amplifier at least 12 times a minute during burner operation and shuts down the boiler if the

amplifier fails.

f 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.

g A 220/240 Vac to 120 Vac 10 VA step-down transformer (not provided) must be used to drive the shutter.
