APPLICATION
The C7027A, C7035A, C7044A and C7927A Minipeeper
®
Ultraviolet Flame Detectors detect the ultraviolet radiation
emitted by combustion flames. The flame detectors are used
with Honeywell flame safeguard controls to provide flame
supervision for gas, oil, or combination gas-oil burners.
FEATURES
• C7027A, C7035A, and C7044A Flame Detectors are used
with RA890G devices or R7249A, R7290A, R7749B and
R7849A,B Amplifiers and the appropriate Honeywell
controls.
• C7927A is used with only the R7851B Flame Amplifier and
the 7800 SERIES controls.
• C7044A may also be used with the following 50 Hz
Honeywell combustion controls/amplifiers:
— R4341/R7323
— R4343/R7323
— R4344/R7323
• C7027A/C7927A has an integral collar threaded (internal
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.

replaceable.
• Two C7027A, C7035A or C7044A Flame Detectors can be
wired in parallel for difficult flame sighting installations.
(C7927cannot be used in parallel.)
• C7927A1016, C7027A1049, C7027A1064, C7027A1072
come with 1/2-in. spud connection for electrical wiring.
