Flame Sensor
The pilot flow adjustment is set to maximum at the
factory and should not need to be adjusted. The pilot
flame should envelope ⅜” to ½” (10 to 13mm) of
the Flame sensor (see Figure 39). 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 38 for location on
valve).
2. Turn the adjustment screw clockwise to decrease
or counterclockwise to increase pilot flame.
