If it is found that there is excessive draught in the chimney then a
draught stabiliser should be tted. Fitting of a draught stabiliser will
affect the requirement for the permanent air supply into the room
in which the stove is tted 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 uepipe where it
is not intended for the chimney to be swept through the appliance.
Hearth
The hearth should be able to accommodate the weight of the stove
and its chimney if the chimney is not independently supported. The
weight of the stove is indicated in the brochure.
The stove should preferably be installed on a non-combustible he-
arth of a size and construction that is in accordance with the provisi-
ons of the current Building Regulations Approved Document J.
The clearance distances to combustible material beneath, sur-
rounding or upon the hearth and walls adjacent to the hearth should
comply with the guidance on the separation of combustible mate-
rial given in Building Regulations Approved Document J and also in
these stove instructions.
If the stove is to be installed on a combustible oor 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 stove and 15 cm to each side mea-
suring from the door of the combustion chamber.
Combustion air supply
In order for the stove to perform efciently and safely there must be
an adequate air supply into the room in which the stove is installed
to provide combustion air. The provision of air supply to the stove
must be in accordance with current Building Regulations Approved
Document J. An opening window is not appropriate for this purpose.
Connection to chimney
Stoves may have a choice of either a rear or top ue gas connector
that allows connection to either a masonry chimney or a prefabri-
cated factory made insulated metal chimney in accordance with their
instructions. In some cases it may be necessary to t an adaptor to
increase the diameter of the ue to the minimum required 150 mm
section of the chimney or liner.
Commissioning and handover
Ensure all parts are tted in accordance with the instructions.
On completion of the installation allow a suitable period of time for
any re cement and mortar to dry out, before lighting the stove.
Once the stove is under re check all seals for soundness and check
