Ideal Burner Manifold Assembly CXi 120 077537

The Ideal 077537 is a burner manifold assembly used on Ideal Commercial Concord gas boilers. It forms the gas-carrying section that feeds the burner head, distributing the gas/air mixture so combustion stays even across the burner surface. It is a manufacturer-supplied assembly rather than a single service item, so it is replaced as a complete unit when the manifold itself is damaged or its injector ports are worn.

• The burner fails to light or lights unevenly, with flame roll-out or a delayed ignition bang.
• Combustion readings drift out of tolerance and cannot be corrected by servicing or adjustment.
• Visible corrosion, cracking or distortion on the manifold body or its injector ports.
• Soot or heavy carbon deposits building up around the burner head despite correct gas pressure.
• A smell of gas at the manifold joints that does not clear after resealing.

• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• Confirm the boiler model and serial number against the compatibility list before ordering, as the Concord CXDI, CXSI and CXi ranges use different assemblies.
• Check the alternative manufacturer code 1174537 on the existing component or in the boiler manual to confirm the match.
• Inspect the burner gasket and sealing faces at the same time, as these are normally disturbed during removal and refitting.
