Hearth; Combustion Air Supply; Installation - RAIS Q20 Instructions For Installation, Use And Maintenance Manual

ENGLISH RAIS ­ manual for Rais Q­20
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 non­combustible 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
non­combustible 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. An opening window is not appropriate for this
purpose.
Installation
It is prohibited to carry out unauthorised alterations to the stove.
There must be plenty of fresh air in the room where the stove is being installed, in order
to ensure proper combustion. Note that any mechanical exhaust ventilation ­ e.g. an
extraction hood ­ may reduce the air supply. Any air grilles must be placed in such a
manner, that the air supply is not blocked.
Building Regulations Approved Document J gives specific guidance on the required
permanent ventilation into the room for combustion air of solid fuel appliances.
The floor structure must be able to carry the weight of the wood burning stove, as well
as the weight of a chimney, if necessary.
When you choose where to set up your RAIS wood burning stove, you should consider
the heat distribution to the other rooms. This will enable you to get the best use out of
your stove.
The stove should be set up at a safe distance from inflammable materials.
See the manufacturer's plate on the wood burning stove.
