Ideal Return Manifold Imax Xtra F160 F320 174442

The Ideal 174442 is a return manifold used on Ideal Commercial Imax Xtra boiler units. It forms part of the hydraulic circuit, collecting and directing returning heating water back through the appliance so flow is distributed correctly across the heat exchanger and connected circuits. The part is listed under the Caradon manufacturing reference and is supplied as a service replacement for the Imax Xtra range.

• Water weeping or visible staining around the manifold body or its connection points
• Persistent pressure loss on the system that cannot be traced to any other component
• Uneven heating across the boiler circuits, suggesting restricted or disrupted return flow
• Scale, sludge or corrosion debris building up inside the manifold and reducing bore size
• Joints that will not seal after re-making, indicating distortion or thread damage

• Confirm the appliance model and serial number against the compatibility list before ordering
• Check the existing manifold for the alternative number 1780694 where the original marking is unclear
• Inspect the mating faces and seals at the same time, as these are commonly disturbed during removal
• Work on the appliance should be carried out by a competent engineer in line with the manufacturer's instructions
