must be taken of the guidance on the separation of combustible material given in Building
Regulations Approved Document J and also in these boiler instructions.
If it is found that there is excessive draught in the chimney then a draught stabiliser should be fitted in the
chimney above the chimney above the flue pipe connection. Fitting of a draught stabiliser will affect the
requirement for the permanent air supply into the room in which the boiler is fitted in accordance with
Approved Document J (see also combustion air supply).
Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping the chimney and
connecting fluepipe.
Hearth
The hearth should be able to accommodate the weight of the boiler and its chimney if the chimney is not
independently supported. The weight of the boiler is indicated in the brochure.
The boiler should preferably be installed on a non-combustible hearth of a size and construction that is in
accordance with the provisions of the current Building Regulations Approved Document J.
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 Building
Regulations Approved Document J and also in these boiler instructions.
If the boiler is to be installed on a combustible floor surface, it must be covered with a non-combustible
material at least 12mm thick, in accordance with Building Regulations Approved Document J, to a distance of
30 cm in front of the boiler and 15 cm to each side measuring from the door of the combustion chamber.
Combustion air supply
In order for the boiler to perform efficiently and safely there must be an adequate air supply into the room in
which the boiler is installed to provide combustion air. The provision of air supply to the boiler must be in
accordance with current Building Regulations Approved Document J. An opening window is not appropriate
for this purpose.
Connection to chimney
All boilers have a flue gas connector that allows connection to either a masonry chimney or a prefabricated
factory made insulated metal chimney in accordance with the instructions. This connection should never be
reduced in diameter to lower than that of the flue gas connector of the boiler. In some cases it may be
necessary to fit an adapter in the connection pipe to increase the diameter to the required minimum diameter
of 150 mm for burning wood fuel in accordance with UK regulations. Any connections should be made gas-
tight and sealed with a suitable sealing agent such as fire cement.
Connection to the central heating system
The boilers may be installed on either open vented or sealed fully pumped systems. The water system must
be properly vented and a double-feed indirect cylinder to the current specification in issue BS 1566 Part 1 for
double indirect cylinders is necessary where there is a combined hot water and central heating system.
During installation caution must be made on the need for a gravity heat-leak radiator or towel rail to dissipate
heat when the pump is off and the minimum load for this function.
The central heating system must be in accordance with BS EN 14336:2004: Heating Systems in Buildings.
