Ideal Flow Manifold Imax Xtra F240-F480 174438

The Ideal 174438 is a flow manifold manufactured for the Ideal Commercial Imax Xtra range of commercial boilers. It sits in the primary water circuit and distributes flow from the appliance pipework into the heat exchanger assembly, so each section receives an even share of the circulating water. A restricted or damaged manifold shows up as uneven heat distribution, poor temperature control and pressure-related faults on the boiler controls.

• Uneven heating across the heat exchanger sections, with some areas running noticeably cooler than others
• Localised overheating, kettling or noise from the primary circuit
• Water weeping or staining around the manifold joints and connections
• Flow or differential pressure faults logged by the boiler controls
• Visible corrosion, scale build-up or cracking on the manifold body

• Confirm the appliance model and serial number against the compatibility list before ordering.
• Match the existing component against part number 174438 and alternative number 1780676.
• Inspect the joint seals and gaskets at the manifold connection while the appliance is open, as these are disturbed during removal.
