2.2 FIRE PLACE OPENING
2.2.1 The front opening of the fire place must be between 415 and 420mm
wide, and between 563 and 570mm 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.
See figure 3 below.
