What it is

The Baxi MGD86612 is a 1000mm flue extension with 80/125mm concentric diameters, manufactured by Baxi for use on compatible Baxi boiler flue systems. It extends the horizontal or vertical flue run where the standard terminal length is insufficient to reach the required termination point. The extension is supplied uncut, allowing the installer to trim it to the exact length required on site.

Before you order

  • Confirm the flue diameter of the appliance is 80/125mm before ordering.
  • Check the maximum permissible flue length and equivalent length allowances for the specific boiler, as extensions add resistance to the flue run.
  • Verify that the planned extension length is achievable after trimming and that joints and supports will be fitted in line with the installation instructions.
  • Check whether the flue route requires additional elbows, brackets or a terminal, as these are separate items.
