Frequently Asked Questions
What is the Honeywell C7027A1023?
It is a Honeywell Minipeeper ultraviolet flame detector used with compatible burner flame safeguard controls for combustion flame supervision.
What type of flame does C7027A1023 detect?
The detector senses ultraviolet radiation emitted by combustion flames. Honeywell identifies applications involving gas-fired, oil-fired and coal-fired burners.
How long are the detector lead wires?
The C7027A1023 includes two lead wires measuring 8 feet (96 inches or approximately 2438 mm).
What is the operating temperature range?
The specified ambient operating temperature range is -18°C to +102°C (0°F to 215°F).
What mounting connection does this detector use?
It uses an integral collar with 1/2-14 NPSM internal threads for installation on a compatible 1/2-inch sighting pipe.
What are its physical dimensions?
The manufacturer drawing indicates an overall length of approximately 102 mm and a diameter of approximately 27 mm.
What is the maximum pressure rating?
Honeywell specifies a maximum pressure rating of 5 psi (34.5 kPa) when the detector is correctly installed.
Which Honeywell flame amplifiers can be used?
The Honeywell combustion catalog lists amplifier families including R7249A/B, R7849A/B, R7749B, R7259 and R7290. The complete flame safeguard control and amplifier combination must be verified before installation.
Can this detector be used for continuous burner operation?
The C7027A Minipeeper is intended for intermittent operation. Honeywell requires the burner to recycle at least once every 24 hours. Continuous-operation systems require an appropriately specified detector and flame safeguard arrangement.
Can its ultraviolet sensing tube be replaced in the field?
No. Honeywell specifies that the C7027A ultraviolet sensing tube is not field replaceable.
Can C7027A1031 replace C7027A1023?
Do not assume direct interchangeability. The variants have different published ambient temperature specifications. Confirm the complete model, flame amplifier compatibility, wiring, mounting and burner safety requirements.
What should be checked before ordering?
Confirm model C7027A1023, manufacturer material number C7027A1023/U, 8-foot lead wires, 1/2-inch sighting pipe connection, -18°C to +102°C ambient rating, compatible flame safeguard control, burner duty cycle and the required installation conditions.
