The
36J22/24/54/55 combination gas valves are de-
signed for direct spark ignition (DSI) and hot surface
ignition (HSI) system applications. These valves
are equipped with redundant and main solenoid
valves that control gas flow to the main burners, a
pressure regulator and a two-position on/off switch
for regulation and electrical shut-off of the solenoid
valves. The
