Hamworthy Flue Pipe 50mm x 15m 573407114

The Hamworthy 573407114 is a polypropylene (PP) flue pipe supplied at 50 mm diameter in a 15 m length. It forms part of the flue system on Hamworthy appliances, carrying products of combustion from the heat exchanger to the point of discharge. The supplier catalogues this item under miscellaneous parts, which reflects its role as a length of flue material rather than a self-contained assembly.

Polypropylene is the standard material for the wet, acidic condensate conditions found in modern condensing flue runs, so the pipe is suited to both the flue gas path and the condensate that forms along it. The 50 mm bore keeps pressure drop low over longer runs, and the 15 m length allows a complete run to be cut and jointed on site rather than assembled from short sections.

• Visible cracks, splits or crazing along the pipe wall
• Sections that have become brittle or discoloured with age
• Condensate weeping from joints or running down the outside of the pipe
• Joints that no longer seal, or seals and gaskets that have hardened and perished
• Flue gas odour around the run, or combustion readings drifting outside tolerance on service

• Check the appliance model, GC number and serial number against the compatibility list to confirm this part number applies
• Confirm the existing flue diameter and run length match 50 mm and 15 m, and plan cuts and joints accordingly
• Obtain replacement seals or gaskets if the run is being re-jointed during the same visit
• Confirm the route, termination and any extensions against the appliance installation instructions before fitting
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
