The front face of the fireplace should be reasonably flat over the area covered by
the hotbox top and side flange seals to ensure good sealing. These faces should be made
good if necessary.
The fireplace floor should be reasonably flat to ensure that a good seal with the hotbox
can be made.

For a shelf up to 150mm deep
Minimum height = 700mm.
•
For a shelf deeper than 150mm
Minimum height = 700mm + 12.5mm for every 25mm depth over 150mm.

They may scorch or become discoloured when close to a heating appliance. Please bear
this in mind when installing.
