1.2.3 Fire protection distances to combustible
components and furniture
Please keep the distances listed in the following
table to flammable components and furniture:
TYPE
B ² flex BOX
*Please note that the BOX may only be stacked up
totheheightofthemarkingsonbothitslateral front edges.
A spacing of at least 4 cm must always be maintained
between the stacked wood and the bottom of thesteel
bodyofthestove.
Spark protection / protection of the floor
If the stove is placed on a combustible floor (eg. wood,
laminate, carpet) a floor plate made of non-combustible
material is required.
The floor plate can bei made of different materials such as
safety glass or steel. The bottom plate must overtop the
front of the stove by at least 50 cm (from combustion
chamber opening) and laterally by at least 30 cm.
1.3 Connections
The flue gas nozzle of the B² flex can optionally be
mounted either at the top or rear of the stove body. The
unused flue gas conduit has to be closed with the provided
cover.
1.3.1 Connection to a chimney
The connection to the chimney is to be carried out with
appropriate connection material which can be obtained as
an accessory. Please use the support of your Bullerjan-
authorized dealer or your master chimney sweep when
connecting your wood stove. The diameter of the
connection nozzle is 150 mm.
The connecting piece between the stove and exhaust
system should be as short as possible, straight and laid
ascendingly. At least one cleaning opening should be
available for the purpose of cleaning the connecting pipes.
The combustion chamber, all air supply channels in the
combustion chamber as well as the connecting pieces to
the chimney must be cleaned in the event of soiling, but at
least once during and after the heating season. For this
work we recommend the use of a commercially available
ash vacuum cleaner.

1.3.2 Required characteristics of the chimney
The Bullerjan B² flex require their own chimney.
Whether the multiple use of a chimney in your personal
housing situation is reasonable and possible, has to be
clarified with your master chimney sweep. In the case of
the concurrent operation of several fireplaces, account
FLOOR
has to be taken of the special ventilation requirements,
among others; an adequate fresh air supply has to be
0 cm*
ensured.
The Bullerjan B² flex is equipped with an automatically
closing combustion chamber door.
Draught of the chimney
Insufficient draught of the chimney: Regardless of the
results, which a chimney calculation program calculates
after entering the presented values, it has to be verified
that the chimney in the cold state has a basic draught/
under pressure of at least 5 Pa. In the case of insufficient
basic draught, flue gas can be discharged into the
installation room, during the ignition phase.
Excessive draught of the chimney: The maximum
draught
exhibits during the heat ing operation, must not exceed
16 Pa. If the draught is too high, the wood burns much
too quickly and too hot, and the stove can not unfold its
heating and environmental qualities. In addition, a
significantly too high chimney draught can lead to
damages of the wood stove. This could lead to a
malfunction of the wood stove and a possibly leak of flue
gas in the installation room.
Insofar as your chimney develops excessive draught, an
easy to install, mechanical draught regulator for the
chimney can already provide an efficient remedy for
excess draught. Please consult your chimney sweep.
The Bullerjan GmbH can only warrant the operational
reliability and the stated thermal performance of the B²
flex insofar as sufficient fire technical dimensioning of
the chimney is confirmed by calculation according to EN
13384.
