Dunbrik Mini Clearflow Gas Flue Block System Components

This system is a neat and efficient method of providing a flue for domestic gas fires in a new property. Fires must be suitable for ’pre-cast flues’, which includes many ‘living flame effect’ fires. The flue blocks are built into a party wall, the inner leaf of an exterior wall or against a partition wall and terminate at roof level through a gas flue terminal. In many cases there is no chimney breast intruding into the living area.

Flue blocks UKCA marked from 18th June 2021.
