What it is
The Alpha 1.039944 is a gas valve used on Alpha E-Tec and Evoke gas boilers. It regulates the flow of gas to the burner, working with the boiler's control electronics to match gas input to the heat demand. The valve is a serviceable component and is replaced as a complete unit.
Signs this part needs replacing
- The boiler fails to light or locks out repeatedly on an ignition fault.
- Flame is unstable, drops out shortly after ignition, or the burner will not modulate.
- Gas input does not respond to demand, so the boiler runs hot or fails to reach temperature.
- The valve body shows signs of leakage, contamination or physical damage.
- Fault codes relating to gas valve or flame detection appear on the boiler display.
Before you order
- Confirm the boiler model and GC number against the compatibility list, as the same appliance family can use more than one valve variant.
- Check the part number on the existing valve matches 1.039944 or 039944 before ordering.
- Inspect the sealing washers and joints on removal and replace them where the manufacturer's instructions require it.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
