nect wires from Hot Surface Igniter (HSI) and Flame
Sensor. Disconnect the two wires from the Low Gas Pres-
sure Switch (LGPS) located on the gas valve.
3. Support the manifold and remove the 4 screws that secure
the manifold assembly to the burner box and set aside.
4. Note the location of the green/yellow wire ground wire for
re-assembly later. See Fig. 2.
