Ideal Gas Header Assembly Super4 V450/500 101085

The Ideal gas header assembly, part 101085, is a gas-carrying component used on Ideal Commercial Concord Super Series 4 appliances in the V450 and V500 sizes. It sits within the gas supply path of the boiler, feeding the burner arrangement, and is supplied as a complete assembly rather than as individual fittings.

It is a commercial boiler spare, so it is normally ordered by engineers working on Concord Super Series 4 plant rather than on domestic wall-hung units.

• A gas leak or pressure drop traced to the header during a tightness test
• Visible corrosion, pitting or surface deterioration on the header body or its joints
• Unstable or uneven flame pattern at the burner, with combustion readings drifting outside the expected range
• Weeping or staining around the header connections that returns after re-making the joints
• Physical damage to the assembly found during a service or strip-down

• Confirm the appliance model and size — this assembly is listed for Concord Super Series 4 V450 and V500 units
• Check the existing part number on the appliance against 101085 and the alternative number 1175390
• Inspect the associated gaskets and seals at the same time, as these are normally disturbed when the header is removed
