As the Sofia Insert Wood Pellet Fire is typically installed

The front facia of the enclosure must be made of a

Built-in fi re clearances don’t apply in a non-combustible cavity. The
above clearance to combustibles on the flue are only applicable
within the fire cavity. Clearance outside this, eg at a ceiling/wall
thimble reverts to 25mm as per ARS fl ue test 05/1185.
If installing a fl oating hearth, ensure sufficient clearance is left below
the file to allow for installation of the chosen surround,
