1. Before installing the wood-burning stove
When installing your wood-burning stove you must make sure that all local laws, incl. those that
refer to national and European standards, are followed. It is always a good idea to consult your
chimney sweep before installation. It must be emphasised that the Hetas controller or Building
control always has to approve the installation, even if a wood-burning stove was installed
previously. You also have to make sure that the placement complies with the current rules in the
Building Regulations for small houses. See the below statement of minimum distances to
flammable materials. If the wood-burning stove is to be installed near a non inflammable there are
no requirements for minimum distance, but we recommend 8-10 cm behind the stove for cleaning
purposes.
2. Distance to flammable material
All distances have been determined in connection with approval of the wood-burning stove.
100 mm behind the stove to flammable material.
200 mm beside the stove to flammable material.
900 mm in front of the stove to flammable material.
100 mm behind
200 mm to the side
900 mm in front
The floor underneath the wood-burning stove must be non inflammable or coated with a non
inflammable material. The non inflammable material, e.g. a steel plate, glass plate, slate/ imitation
slate or tile, must be placed so it reaches at least 300 mm in front of the wood-burning stove and at
least 150 mm to each side of the opening of the wood-burning stove.
3. The chimney
The chimney is the lung of the wood-burning stove, i.e. a chimney with good draught is a
precondition for good combustion. You must use a chimney with a diameter of at least Ø150 mm
which is the equivalent of an internal diameter of 175 cm² for your TermaTech stove. It is important
to follow the directions in the Building regulations for small houses and to make sure that the
existing or new chimney is high enough to ensure optimum draught in the wood-burning stove. The
chimney must be of sufficient height so the draught conditions are okay and the smoke does not
