This flame sensor is the direct replacement for many York, Luxaire, Coleman, Coleman-Evcon, Fraser/Johnson, and Air Pro furnaces made by Unitary Products Group. Please note the orientation of the mounting bracket. With the offset pointing to the left at 9:00 o"clock the mounting hole is at approximately 10:00 o"clock. This flame sensor is used on BGD, BGM, BGU, FG8, G8C, GMB, GUB, L8C, MGP, ODF, and UGB models. This part replaces S1-2702-311P, 2702-311P, and 2702-311. Do not clean flame sensors with sandpaper- the grit will melt into glass and the sensor will not work. Clean sensors with steel wool.
