Grant EZ-Fit Flue Systems

What is a flue?

Grant Vortex condensing boilers need to be connected to a flue to remove the combustion gasses.

Even if you are replacing your Grant boiler with a new version, you will require a new flue system too. It is not possible to connect to the old existing flue or liner, due to build up of debris, which could fall back into your new boiler and affect its performance.

Grant EZ-Fit Flue options

Grant has a range of unique EZ-Fit Flues. These are available as low level, high level or vertical kits, for internal and external applications, and even as unique EZ-Flexi liner packs, designed to enable condensing boilers to utilise an existing chimney. It is also possible to convert existing low-level flues to high level after installation.

Apart from the benefits of so many options the Grant EZ-Fit flue systems ensure ‘pluming’ is kept well out of the way of any windows, air vent or doors and out of sight.

Flue Terminals

The flue terminal (end part of flue situated externally) should be positioned so as to avoid combustion gasses accumulating in stagnant pockets around, or entering inside the property. Care should also be taken that the plume from a condensing flue does not cause a nuisance.
