aDjusting the piLot fLame:
The pilot ow adjustment is set to maximum at the factory and should not need to be adjusted. The pilot
ame should envelope ⅜” to ½” (10 to 13mm) of the Flame sensor (see Figure 35). However, should the
need arise, follow Steps 1- 2 below.
1. The adjustment screw can be reached through the front of the unit using a 10 inch long blade head
screw driver (see Figure 34 for location on valve).
2. Turn the adjustment screw clockwise to decrease or counterclockwise to increase pilot ame.
