In order for the stove to perform satisfactorily the chimney height must be sufficient to ensure an adequate draught to
clear the products of combustion and prevent smoke problems into the room.

NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet of the stove to the top of the
chimney should be satisfactory. Alternately the calculation procedure given in BS 5854:1980 may be used as the basis for
deciding whether a particular chimney design will provide sufficient draught.
