Ensure the orange lead from the pilot assembly igniter is securely connected to
the terminal labeled “I” and the white lead from the flame rectification sensor is
securely connected to the terminal labeled “S” on the control module. (Fig. 58)

Make sure the orange and white leads from the module are securely connected to
the terminals labeled “PILOT” on the valve body. (Fig. 61)
