Ventilation; Floor, Walls - Dovre 450 Mode D'emploi

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 emanations
into the room.
If necessary, you can have a ventilation grille installed in the room so that there is a
constant flow of fresh air. This precaution is certainly necessary in well-insulated
rooms with mechanical ventilation.
Be sure not to use other air-consuming appliances, like a heater, a cooking hood, a
bathroom ventilator, in the same room or in the house while the stove is burning; or
make sure to have an extra ventilation 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. If you purchased a freestanding stove, this distance
should be at least forty centimetres.
Combustible floors require sufficient protection against radiant heat by means of a
fireproof protective plate. Any rug is to be kept at a distance of at least eighty centi-
metres from the fire.
