Ideal Flow Manifold 174439

The Ideal 174439 is a flow manifold used on Ideal Commercial appliances. It distributes heating water from the appliance into the separate circuits of the heat exchanger or system pipework, so each branch receives an even share of flow. The manifold is listed under part type MANIFOLDS and carries the alternative number 1780722.

• Uneven heat output across the circuits served by the manifold, with some branches running noticeably cooler than others.
• Reduced flow through one or more branches, causing the appliance to run hotter than normal or to cycle.
• Visible weeping, staining or scale tracking at the manifold joints or sealing faces.
• Kettling, gurgling or rushing noise from the manifold area when the appliance fires.
• Corrosion, pitting or distortion on the manifold body found during a service or strip-down.

• Confirm the appliance model and, where available, the serial number against the compatibility list before ordering.
• Check the part number stamped or printed on the existing manifold matches 174439 or the alternative number 1780722.
• Inspect the manifold seals, gaskets and O-rings on the appliance at the same time, as these are commonly disturbed during removal and refitting.
• Work on the appliance should be carried out by a competent engineer in line with the manufacturer's instructions.
