Standard Opening Pressure Regulation (VR8200A,M, and VR4200A, M)During the ON cycle, the servo pressure regulator provides close control of outlet pressure, even if inlet pressure and flow rate vary widely. Do not remove seals until ready to connect piping.Follow the appliance manufacturer instructions if available; otherwise, use the instructions provided below. The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems. Adjustable servo regulator effectively maintains almost constant gas output pressure under wide fluctuation in gas supply pressure. A1/{;_Fe o(*=`. 4 41 Gas valves are not serviceable; the following are simple troubleshooting and description of how gas valves operate. The gas valve cannot be repaired in the field. Now I'm sure my problem's the thermopile. If necessary, adjust the pressure regulator to match the appliance rating.
