Hearth
The hearth should be level and 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 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 stove instructions.
If the stove 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 stove and 15 cm to each side measuring from the door of the combustion chamber.
Combustion air supply
In order for the stove to perform efficiently 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. Special attention should be taken in
newer build properties where the
design air permeability is less than 5m

. Approved Document J gives
more information on this. An opening window is not appropriate for this purpose.
The fitting of an external air kit direct to outside air must not be considered substitute for installing
the appliance with a permanently open air vent in compliance with ventilation requirements stated in
Approved Document J. Please reference ADJ for further guidance.
Connection to chimney
Stoves may have a choice of either a rear or top flue gas connector that allows connection to either a
masonry chimney or a prefabricated factory made insulated metal chimney in accordance with their
instructions. In some cases it may be necessary to fit an adaptor to increase the diameter of the flue to the
minimum required 150 mm section of the chimney or liner. All joints in the connection between the stove and
the chimney must be made gastight using fire cement and where necessary fire-proof rope infill. Means
should be made for sweeping the entire length of the flue, be that through the appliance or by suitable
sweeping hatch in the flue.
Commissioning and handover
Ensure all parts are fitted in accordance with the instructions.
On completion of the installation allow a suitable period of time for any fire cement and mortar to dry out,
before lighting the stove. Once the stove is under fire check all seals for soundness and check that the flue is
functioning correctly and that all products of combustion are vented safely to atmosphere via the chimney
terminal.
On completion of the installation and commissioning ensure that the operating instructions for the stove are
left with the customer. Ensure to advise the customer on the correct use of the appliance and warn them to
use only the recommended fuel for the stove.
Advise the user what to do should smoke or fumes be emitted from the stove. The customer should be
warned to use a fireguard to BS 8423:2002 (Replaces BS 6539) in the presence of children, aged and/or
infirm persons.
