Choosing and fitting
When replacing a UV flame sensor of this type, verify the thread connection is 1/2-14 NPSM internal thread for mounting on a 1/2-inch inspection tube. Choose the wire length option (6 ft or 24 ft) that matches the existing wiring. Ensure the sensor is compatible with the flame amplifier in use; common Honeywell amplifiers are R7249A, R7290A, R7749B, R7849A, and R7851B. Also check the maximum allowable pressure (5 bar) and inspect the flange seal (129685) for wear before installation.
