1.3.2 Chimney
The fire assessment has to be made according to DIN EN
13384 with the triple of values indicated in table 1.
We can only assure operational safety and the nominal heat
capacities of Bullerjan
stoves if sufficient measurements of the
chimney in accordance with DIN EN 13384 has been proven
and certified by your professional chimney sweep.
Draught of the chimney:
Regardless of the results that a
chimney calculation program outputs after entering the present
values, it has to be taken into consideration that in the cold
state the chimney exhibits a basic draught / under pressure in
the amount of at least 5 Pascal (Pa).
In the event that the basic draught is too low, flue gas can
ingress in the installation room, in the course of the initial
combustion.
1.3.3 Connection to external combustion air supply
The models
dot
are equipped with a connection
nozzle for the supply of combustion air from outside
the installation room.
A commercial aluminium flex pipe with a diameter of 100
mm
can be used to connect.
If the supply of combustion air from the outside is
not
necessary, this nozzle remains open and unused.
Please get advice from your Bullerjan
specialised dealer
or Bullerjan GmbH.

Connections
The connection piece between the stove and the exhaust
gas system should be as short and straight as
and laid rising. Connection points are to be sealed off. At
least
one cleaning opening should be available to clean
the
connection piece.
The Bullerjan dot can be mounted on the top or rear of the
stove body.
The non-used flue gas supply is closed by the supplied cover.
The maximum draught that the chimney exhibits during the
heating operation must not exceed 16 Pascal (Pa). Insofar as
the draught is too high, the wood burns too quickly and the
stove cannot unfold its full heating and environmental qualities.
Furhtermore, an excessively high draught in the chimney may
result in damage of the stove.
For the regulation of the draught of the chimney, we suggest an
automatic draught regulation located between the stove and
the chimney.
Please contact your authorized retailer or chimney sweep.
Please note:
If you run multiple fireplaces at the same time,
special ventilation requirements must be taken into account.
Please ensure in this case a controlled ventilation of fresh air
by opening windows and doors regularly.
Cleaning the chimney:
The chimney must be
regularly cleaned by a chimney sweep, normally once
per year.
