INSTALLATION INSTRUCTIONS
Operator: Save these instructions for future use!
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 ow to the main burners, a
pressure regulator and a two-position on/o switch
for regulation and electrical shut-o of the solenoid
valves. The 36J24 and 36J55 are also equipped
with a slow-opening pressure regulator for softer
lighting characteristics. When the second solenoid
on 2-stage valves is energized the valve operates
at the second stage (high) outlet pressure setting.
