What it is

The Ideal 172055 is a complete draught diverter assembly for the flue system of Ideal Commercial Concord boilers. It mounts at the flue outlet and stabilises the draught across the appliance, admitting dilution air and allowing combustion products to discharge safely while protecting the burner and heat exchanger from downdraught. Supplied as a complete assembly, it is the direct replacement for the earlier 8358-8504 draught diverter.

Signs this part needs replacing

  • Corrosion, rust staining or perforation on the diverter body or flue spigot
  • Soot deposits or dark staining around the diverter, suggesting combustion products are not clearing correctly
  • Combustion readings drifting from the commissioned figures, or spillage detected at the draught diverter
  • Downdraught, flame instability or pilot problems while the appliance is running
  • Distortion or mechanical damage to the assembly after flue work or handling

Before you order

  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
  • Check the appliance model and serial number against the compatibility list before ordering.
  • Confirm the number on the existing component matches 172055 or the earlier 8358-8504.
  • Inspect the flue joint seals and gaskets at the same time and renew them where they are perished or compressed.
