We recommend that the stove be installed at least 10 - 15 cm from masonry, in order to allow
heat to circulate and to facilitate the cleaning of the inside and outside of the stove. A layer of
wallpaper on a brick wall is normally viewed as non-flammable material.
the floor
If the stove is installed on a flammable floor, national and local regulations must be observed
with regard to the size of the non-flammable underlying surface that must cover the floor be-
neath the stove. The underlying surface must naturally be able to bear the weight of the stove
and, if applicable, the steel chimney.
Distance to furniture
The minimum clearance to combustible materials in front of the stove is 800 mm. for Morsø
7800 and 900 mm. for Morsø 7900. The minimum distance to combustible materials must be
observed; furthermore, it should be considered whether furniture and other items will dry out
if placed near the stove.
A wood-burning stove gets hot when it is fired. Caution must therefore be observed, particu-
larly with regard to children touching the stove.

1.5 the chimney

If local regulations permit, the stove may be connected to a chimney already serving another
fireplace (such as an oil-burning stove or another wood-burning stove). Attention should be
paid to any requirements concerning the location of flue pipes if two or more fireplaces are
Distance
connected to the same chimney.
The wood-burning stove must never be connected to a chimney to which a gas-burning stove
is already connected.
An efficient, modern stove places great demands on the chimney, so you should get the chim-
ney sweep to evaluate chimney.
The aperture of the chimney must comply with national and local regulations. In general, the
aperture area should measure at least 175 cm2 (150 mm diameter) for wood-burning stoves.
An overly large chimney aperture will mean that too much energy will be required to heat the
chimney sufficiently to achieve an acceptable draught in the chimney. If you have a brick chim-
ney with a large aperture, we recommend that you install an insulating chimney liner of the
Distance
proper diameter. This will increase the draught, and improve the fuel economy.
There are no requirements with respect to specific chimney heights, but a chimney must be
tall enough to provide a good draught, and to ensure that the smoke does not cause any prob-
lems. As a general rule, there will be a satisfactory draught if the chimney extends 4 metres
above the stove and at least 80 cm above the spine of the roof.
If the chimney is located along the side of the house, the top of the chimney should never be
lower than the spine of the roof or the highest point on the roof. Please note that there are of-
ten national and local regulations concerning the location of chimneys in houses with thatched
roofs. Please see section 1.9 on Draught.
The chimney and the flue pipe must be fitted with cleaning doors, which must be at least the
same size as the chimney's aperture area.
The chimney must be accessible for external inspection, and it must be possible to access the
cleaning doors and the chimney if it is to be cleaned from the top (e.g. steel chimneys).
