between the wall/roof and the roof duct.

Roof duct existing flue duct C31S

With an existing flue duct, you can use two connectors.
At the top use the ventilation plate with a draught
increasing hood. Connect a flue liner or flexible flue liner to
this, fitted through the existing duct.
Check the flue duct for any leaks which may cause under
pressure. In turn this will prevent the closed system from
functioning properly.
With a very old flue, use two flexible pipes. The inner pipe
must be centred in the middle, to prevent blockages.
At the entrance to the flue duct, mount the cover plate.
Ensure this is well sealed.
For distances to adjoining walls, coverings and windows, please
