FIRE PLACE OPENING AND CHIMNEY CATCHMENT SPACE
The front opening of the fire place must be between 760mm and 790mm wide,
and between 870mm and 880mm high. If the opening exceeds these dimensions
then a surround must be constructed from suitable non-combustible material to
produce a correct size opening. The fire must be suitably sealed to the fireplace
opening to prevent leakage. See below in figure 2.
When installing into a brick built chimney, you must ensure that there is sufficient
depth to accomodate any debris which may fall from the chimney. This depth
must be sufficient to accomodate 12 litres of volumetric space in a conventional
brick built chimney.
