Choosing and fitting
When selecting a gas valve of this type, ensure the connection thread, inlet/outlet diameters, and mounting orientation match the existing setup. Verify the supply voltage (220–240 V, 50 Hz) and current consumption (0.048 A) are compatible. Check the maximum operating pressure (45 mbar) and ambient temperature range (-15–60 °C) against system requirements. The valve must be installed upright with proper clearance for the side outlet and pilot gas connection.
Signs of failure
Common failures include sticking or leaking valves due to debris or wear, leading to unstable gas flow or failure to ignite. Symptoms may include burner not lighting, fluctuating flame, or gas odor. Check the fine-mesh filter for clogging (not cleanable) and inspect the pressure relief valve and servo controller for proper operation. Verify electrical connections and that the valve receives correct voltage.
