Installation distance in case of combustible wall
To find out whether the wall next to where the stove is going to be installed is flammable,
you should contact your building contractor or the local building authorities.
The hearth should be able to accommodate the weight of the stove. The chimney must
be independently supported by wall brackets or a ceiling support plate. The weight of the
stove is indicated in the brochure.
The stove should always be installed on a non­combustible hearth of a size and
construction that is in accordance with the provisions of the current UK Building
Regulations Approved Document J.
If the stove is to be installed on a wooden floor, it must be covered with a
non­combustible material at least 12mm thick, in accordance with UK Building
Regulations Approved Document J, to a distance of 300 mm in front of the stove and
150 mm to each side measuring from the door of the combustion chamber.
The clearance distances to combustible material beneath, surrounding or upon the
hearth and walls adjacent to the hearth should comply with the guidance on the
separation of combustible material given in UK Building Regulations Approved
Document J and also in these stove instructions.
Installation distances for non combustible wall
We recommend a minimum distance to non combustible material of 50mm ( F ) for
cleaning considerations.
Using uninsulated flue pipe, the minimum distance to a combustible wall must be
450mm or 225mm if the wall is heatshielded ( see Section J of the Building Regulations )
from the flue pipe.
