Controlling Combustion Air - Dovre 640WD Installation Et Mode D'emploi

Open stacking
If the logs are stacked openly, the wood will burn
quickly as the oxygen can reach each log easily. If
you want to use the stove for a short while, make an
open stack.
Compact stacking
If the logs are stacked tightly, the wood will burn more
slowly as the oxygen can only reach some logs eas-
ily. If you want to burn wood for a longer period, make
a compact stack.
4. Close the door of the appliance.
5. Close the primary air inlet by moving the control
slide to the central position.

Controlling combustion air

The appliance has various features for air control; see
next figure.

The appliance has one air slide that regulates both the
primary and the secondary air inlet. If the air slide is as
far to the left as it will go, the primary and secondary
air inlets are open. As the air slide is moved more to
the right, this closes off the primary air inlet and then
the secondary air inlet. If the air slide is slid as far to
the right as it will go, a small air vent remains open to
allow for post-combustion under the baffle plate.
Advice
09-20500-018
Never burn wood with an open door.
Regularly burn wood with intense roaring fires.
If you burn at a low setting frequently, tar and
creosote may be deposited in the flue. Tar and
creosote are highly combustible substances.
Thicker layers of these substances may catch
fire if the temperature in the flue increases sud-
denly. By allowing the fire to burn very
intensely regularly, layers of tar and creosote
will disappear.
Low intensity fires can also cause tar deposits
on the stove window and door.
When the outside temperature is mild, it is bet-
ter to burn wood intensely for a few hours
instead of having a low intensity fire for a long
period of time.
Control the air supply using the air vent.
