exhaust hood must not narrow the chimney's outlet and should be designed in a
way that wind will not hinder, but promote the smoke flow.
•
Especially if the flue runs through unheated rooms or outside the house, further
insulation is necessary. Metal chimneys, or parts of the chimney outside heated
rooms should always have double-walled, insulated flues. The part of the chim-
ney outside the roof should always be insulated.
•
The chimney should be high enough (at least four metres) and should end in a
zone that is clear of nearby buildings, trees or other obstacles. The rule of
thumb here is: 60 cm above the ridge of the roof. If the distance between the
ridge and the chimney measures more than three metres, see the dimensions
stipulated in the illustration below. Depending on the presence of nearby build-
ings or trees, the chimney should be higher.
3.1.2. Ventilation
The burning of wood, charcoal or gas involves oxygen consumption. It is of the ut-
most importance that the room in which the stove is installed should be sufficiently
ventilated.
Insufficient ventilation may disrupt the combustion process and cause the smoke
flow through the chimney to be interrupted, which may lead to smoke emissions
into the room.
If necessary, you can install a ventilation grille to provide a constant flow of fresh air
in the room. This precaution is particularly necessary in well-insulated rooms with
mechanical ventilation.
Ensure not to use other air-consuming appliances, such as heaters, cooking hoods,
bathroom ventilators, in the same room or in the house while the stove is burning;
or make sure to have an extra ventilation grill installed for these appliances.
3.1.3. Floor, walls
A safe distance should be kept between the stove and combustible materials such as
wooden walls and furniture. This distance should be at least forty centimetres for
the side-wall and 30 cm for the back-wall.
The appliance shall be installed on floors with an adequate load-bearing capacity.
Combustible floors require sufficient protection against radiant heat by means of a
fireproof protective plate. Rugs and carpets must be kept at a distance of at least
eighty centimetres from the fire.
