Ideal Flue Manifold Top 150 Kit 176340

The Ideal 176340 Flue Manifold Top 150 Kit is a flue assembly component supplied by Ideal for its commercial boiler range. It sits within the flue path at the top of the manifold, where it helps direct flue gases away from the appliance and maintain correct flow through the internal pipework. The kit is listed under the Ideal Spares brand and carries the alternative number 1782342.

• Visible corrosion, staining or distortion on the manifold top or its sealing faces.
• Flue gas readings outside the expected range for the appliance, with combustion analysis failing to settle after servicing.
• Condensate or water tracking around the flue outlet or manifold joint.
• Soot deposits or discolouration at the manifold connection, suggesting leakage at the joint.
• Repeated lockouts or flame supervision faults that persist after the flue path has been checked.

• Confirm the appliance model and GC number against the compatibility list, as the same flue assembly is not shared across the whole Ideal Commercial range.
• Check the existing manifold top and note whether the sealing gasket or seal kit is being replaced at the same time.
• Compare the part number on the appliance data badge and on the old component with 176340 before ordering.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
