What it is

A flue box assembly for the Potterton Promax range of gas combi and system boilers. It sits at the top of the boiler and directs the products of combustion out through the flue, keeping exhaust gases separate from the room air.

Signs this part needs replacing

  • Visible cracking, corrosion or distortion of the flue box casing
  • Water or condensate leaking from the flue box joints
  • Soot staining around the flue box or boiler casing
  • Boiler locking out on a flue or fan-related fault code

Before you order

  • Confirm your exact Promax variant and rating (e.g. 24HE, 30HE Plus) from the boiler's data badge
  • Isolate the boiler and let it cool before removing the casing
  • Have a Gas Safe registered engineer carry out the replacement
