1� Pilot Solenoid: Orange in colour� Stamped with “NAT”, factory default is set for Natural Gas�
2� Inlet Pressure Tap: Used to test the pressure at the inlet�
3� Manifold Pressure Tap: Used to test the pressure at the manifold�
4� Stepper Motor: This modulates the flame� The stepper motor is only available as an assembly
with the main burner solenoid� Should the stepper motor fail to correctly operate, the valve will
still function but without flame modulation�
5� Main Burner Solenoid: Green in colour� The main burner solenoid gets changed out when the
unit is converted to Propane (along with attached stepper motor)� A conversion kit is signified
with a stamp of the pressure rating “6�4 - 10” along the side of the main burner solenoid� See
Figure 6�
*NOTE: The stepper motor/regulator assembly should never be disassembled*
