1.3 Connections

1.3.1 Connection to a chimney

Bullerjan stoves Free Flow FF18 are always
®
supplied together with a 90° smoke pipe elbow
and a 100 cm long smoke pipe with integrated
throttle valve. This connection material is a
component of the stove and must be fitted during
installation.
Any additional connection material is available as
an accessory.
The respective diameter of the connection pipes
for the stoves is as follows:
Free Flow FF18 Typ 03: 160 mm
Free Flow FF18 Typ 04: 180 mm
The connection piece between the stove and the
exhaust gas system should be as short and
straight as possible and laid rising. Connection
points are to be sealed off. At least one cleaning
opening should be available to clean the
connection piece.
The connection pieces must be cleaned in the
event of soiling, but at least once during and after
the heating period.This can be done with an ash
vacuum cleaner.
The combustion chamber needs it's ashbed on
the floor. Please remove the ash only, when the
ash bed is getting too high. After the heating
period, the combustion chamber should be
completely cleaned. This can be done with an ash
vacuum cleaner.

1.3.2 Chimney

Bullerjan ® hot air stoves FF18 need a chimney of
their own. If necessary and approved by your
chimney sweep, FF18 - models are not suitable
for the multiple configuration of chimneys.
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 calcu-
lation program outputs after entering the present
values, it has to be taken into consideration that in
the cold state the chimney should exhibit 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.
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.
Alternatively, the chimney draft can also be
reduced by throttling the air supply of the stove.
This can be done with the aid of the throttle
device at the rear of the stove.
Lever position vertically
= air supply completely open
Lever position horizontally
= air supply closed
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 by a chimney
sweep, normally once per year.
