Minipeeper® Ultraviolet Flame Detectors

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.

• C7044A may also be used with the following 50 Hz 

Honeywell combustion controls/amplifiers:

— R4341/R7323
— R4343/R7323

— R4344/R7323

• C7027A 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.

• C7044A mounts with a two screw bracket. The UV 

sensor tube is enclosed in a stainless steel housing.

• C7044A has the capability of side or end viewing in 

flame monitoring applications.

• Because of their compact size, the C7027A and 

C7044A are particularly suitable for blast tube 

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.
