Ideal Gas Header Assembly Super Plus 300/400 133360

The gas header assembly is the manifold section that distributes gas to the burner arrangement on Ideal Commercial Super Plus appliances. It is manufactured by Ideal for the Super Plus 300/400 range and the wider Super Plus commercial family. The assembly carries the gas supply from the inlet connection through to the burner injectors, so correct sealing and clean internal passages are essential for stable combustion.

• Gas smell or a detectable leak at the header joints or unions
• Sooting or discolouration around the burner area suggesting uneven gas distribution
• Visible corrosion, pitting or cracking on the header body
• Debris or oxide build-up blocking the internal gasways
• Unstable flame picture or combustion readings that cannot be brought back into tolerance

• Check the appliance GC number and serial plate to confirm the model before ordering
• Note the alternative part number 1176099 when cross-referencing older documentation
• Inspect the mating gaskets and seals on removal and replace them if they are compressed or damaged
