1/2-14 NPSM) for mounting on a one-half-inch sight
pipe.
• C7035A has an integral collar threaded (internal
1-11-1/2 NPSM) for mounting on a one-inch sight pipe.
• C7035A housing meets Underwriters Laboratories Inc.
requirements for rain tightness and complies with
NEMA enclosure standards, types 4 and 4X.
• C7044A mounts with a two screw bracket. The UV

mounting.
• Properly installed, the C7027A, C7035A and C7927 are
pressure rated for 5 psi.
• C7035A ultraviolet radiation sensor tube is field
replaceable.
• Two C7027A, C7035A or C7044A Flame Detectors can
be wired in parallel for difficult flame sighting
installations.
• C7927A is used with only the R7851B Flame Amplifier
and the 7800 SERIES controls.
• C7927A has an integral collar threaded (internal
1/2-14 NPSM) for mounting on a one-half inch sight
pipe.
