Ideal Draught Diverter Assembly 172056

The Ideal draught diverter assembly, part number 172056, is a flue component fitted at the flue outlet of the appliance. It stabilises the draught through the flue and helps maintain a steady path for combustion products leaving the heat exchanger, so the burner sees consistent conditions across the firing range.

It is supplied as a complete assembly and belongs to the Ideal Commercial Concord family of appliances. Because it sits in the flue gas path, it is classed as a gas-carrying part and is replaced as a unit rather than repaired.

• Visible corrosion, rust staining or perforation on the diverter body or its flue connection
• Soot deposits or discolouration around the diverter, suggesting spillage or poor draught
• Combustion readings that drift outside the expected range for the appliance, or a flame picture that changes with flue conditions
• Condensate tracking or staining below the diverter where the assembly meets the flue
• Physical damage or distortion after handling, servicing or flue work

• Confirm the appliance model and serial number against the compatibility list, as Concord variants differ in flue arrangement
• Check the part currently fitted for the previous number 8358-8505 or the alternative number 1178442 before ordering
• Inspect the flue joint and any gasket or seal at the diverter connection, and replace sealing components if they are perished or compressed
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
