The Benchmark gas train P/N
22330-2
operates in conjunction with a Valve Proving System,

. This system monitors the gas pressure on both sides of the Actuator. If the pressure
difference falls below a fixed value, indicating the failure of the Actuator or leakage in the gas
line, it triggers the shutdown of the boiler.
Once the problem has been diagnosed and corrected, the Valve Proving System must be reset
by pressing the red
Reset
switch before the unit is restarted.
