Alpha Gas Manifold 1.018855

The Alpha 1.018855 Gas Manifold is a gas-carrying component used in Alpha CD-series gas boilers. It forms part of the boiler's gas valve assembly, distributing gas to the burner through the manifold outlets. It is supplied by Alpha under part number 1.018855.

• Unstable or drifting gas pressure at the burner, with the boiler failing to hold a steady flame
• Repeated ignition lockouts or flame failure faults traced to the gas valve and manifold assembly
• Whistling, roaring or uneven burner noise suggesting restricted or disturbed gas flow through the manifold
• Visible damage, corrosion or a detectable gas smell around the manifold joints
• Sooting or poor combustion readings linked to incorrect gas delivery at the burner

• Confirm the boiler model and whether it is the natural gas or LPG version, as the listed fits cover both
• Check the existing part number on the manifold against 1.018855 before ordering
• Verify the fault has been diagnosed to the manifold rather than another part of the gas valve assembly
• Gas-carrying components must be fitted and commissioned by a Gas Safe registered engineer
