FIRE PLACE OPENING
2.2.1
The front opening of the fire place must be between 750 and 840mm
wide and between 1025mm and 1050mm high. If the opening exceeds
these dimensions then a surround must be constructed from suitable
non-combustible material to produce a suitable sized opening. Any
surround must be suitably sealed to the fire place to prevent leakage.
