Ventilation Of The Area; Floor And Walls - Dovre 2020 Installation Et Mode D'emploi

The flue or chimney must be airtight and well-
cleaned and guarantee sufficient draught.
A draught/vacuum of 15 - 20 Pa during normal
operation is ideal.
Starting from the flue spigot, the flue must run as
vertically as possible. Changes in direction and
horizontal pieces disrupt the outward flow of com-
bustion gases and may cause soot deposits.
To prevent combustion gases from cooling down
too much, which reduces the draught, ensure that
the interior diameter is not too big.
The flue or chimney should ideally have the same
diameter as the connection collar.
For the nominal diameter: see the appendix
"Technical data". If the smoke channel is well
insulated, the diameter may be slightly bigger
(up to 2x the section of the connection collar).
The section (area ) of the smoke channel must be
constant. Wider segments and (in particular) nar-
rower segments disrupt the outward flow of com-
bustion gases.
When using a cover plate or exhaust hood : make
sure that the cover does not restrict the flue outlet
and that the cap does not impede the outward flow
of combustion gases.
The flue must end in a zone that is not affected by
surrounding buildings, trees or other obstacles.
The flue outside the house must be insulated.
The chimney must be at least 4 metres high.
As a rule of thumb: 60 cm above the ridge of the
roof.
If the ridge of the roof is more than 3 metres away
from the flue: stick to the measurements in the fol-
lowing figure. A = the highest point of the roof
within a distance of 3 metres.

Ventilation of the area

For good combustion, the stove needs air (oxygen).
This air is supplied via adjustable air inlets from the
area in which the stove is installed.
The combustion will be incomplete in case of
insufficient ventilation, which results in toxic
gases being produced and spread through the
area.
As a rule of thumb, the air supply should be
5,5 cm²/kW. Extra ventilation is needed when:
The stove is in an area that is well-insulated.
There is mechanical ventilation, for example a cent-
ral extraction system or an extraction hood in an
open kitchen.
You can provide extra ventilation by having a vent-
ilation louvre fitted on the outside wall.
Make sure that other air consuming appliances (such
as tumble-driers, other heating appliances or a bath-
room fan) have their own supply of outside air, or are
switched off when you use the appliance.

Floor and walls

The floor on which the appliance is placed must have
sufficient bearing capacity. The weight of the appli-
ance is given in the appendix "Technical Data
appendix".
There may not be any electrical wires in the
floor below the appliance and in the walls
around it.
