1.5 The chimney
Only if National or Local Regulations permit are you permitted to connect a stove into a chim-
ney that is shared by another appliance. YOU MUST be aware of any applicable Regulations in
this respect.
The wood-burning stove must never been connected to a chimney to which a gas-burning
stove or appliance is connected.
An efficient modern stove places heavy demands on the chimney, and you should have the
chimney regularly swept and inspected by your approved chimney sweep.
The cross-sectional area of the chimney (at its narrowest point) must comply with National and
Local Building Regulations. Generally, the area needed for a Morsø wood-burning stove instal-
lation should measure at least 175 cm2 (150 mm diameter).
An over-sized chimney is generally hard to keep warm and results in poor draft. In cases
where there is an oversized masonry chimney, it is recommended that the chimney be lined
using an appropriate chimney lining system with the correct internal diameter.
With respect to the chimney termination, all chimneys should terminate in accordance with
National and Local Building Regulations.
Note that National and Local Regulations also apply with regard to the placement of chimneys
and flues in connection with thatched roofs. See the section on Draft Conditions, 1.9.
The chimney or flue system must be equipped with access doors for inspection and cleaning.
The size of the cleaning door in the chimney must at least equal to that of the cross-sectional
area of the chimney.
In situations where the stove is to be fitted into a brick or non-combustible recess, we recom-
mend that the stove is installed with at least 10 - 15 cm clearance to the wall, this will allow
heat to circulate around the stove; also the maintenance of the outside stove is easier. When
applied to masonry, a layer of wallpaper is normally classified as a non-combustible surface.
On the floor
National and Local Building Regulations must again be observed when considering the type,
thickness and area of the hearth to be used in the installation.
One should of course always make certain that the underlying floor surface can bear the
weight of the stove.
Clearances to Furniture
The clearance requirement from the stove to any furniture should be no less than 700 mm. It is
always necessary to assess whether or not any furniture or other objects situated close-by can
be affected by heat, i.e. dried out.
The distance to any combustible material in front of the stove is minimum 700 mm.
The surface of a wood burning stove gets extremely hot when used and therefore special at-
tention to safety is paramount, especially where children or the infirm are present.
The stoves handle also gets hot when the stove is lit, which is why a safety glove is included
with the stove.
