EZ-Fit External Flues (Green System) for outdoor boilers

The Green Flue System can be installed with external Grant boilers when fitted with the relevant starter connectors and elbows. This allows for the extension of an outdoor module’s flue system to be redirected, either vertically or horizontally, to reduce nuisance pluming.
