EZ-Fit External Low Level / High Level Flues (Green System)

Grant EZ-Fit Green System - blackThis external version of the Grant high level and vertical flues is compatible with all Grant Vortex models. Available in a modular form, the system can cater for most installations. The flue is manufactured from a high grade stainless steel, to ensure longevity.

Plume Diverter

Grant’s plume diverter allows internal Vortex models to connect to an external high level/vertical flue arrangement, whilst maintaining the existing balanced/sealed boiler operation. Converting an existing EZ-Fit Yellow System low level flue to an external high level or vertical arrangement without any additional building work, is also straightforward, which is useful when pluming (steam) from the terminal is bothersome.

To alter a Grant Vortex outdoor module/outdoor combination module to high level or vertical conventional flue arrangement, the stainless steel starter elbow can be used. Being fully insulated and having O-ring seals and locking bands, ensures a rigid flue construction at all times.
