A VPS automatically tests that the main gas safety shut-off valves are sealing tight before each burner start, so a leaking valve is caught and the burner is locked out before ignition — required on many larger/automatically-fired burner installations.
RKIC supplies genuine Dungs and Madas valve proving systems.
It runs its leak test as part of the pre-purge/start-up sequence, before the burner control unit is allowed to proceed to ignition — check your burner control unit's wiring diagram for the exact VPS interlock points.
