Floor protection
The floor is to be protected from the radiant heat from
the area of the viewing window (combustion chamber).
In addition, for practical reasons associated with
cleaning it is recommended that you install your pellet
stove on a fireproof base that extends beyond the device
at the back and on the sides by at least 5 cm and at the
front by at least 50 cm. We have floor protection plates
(underlay plates or U plates) in our range of accessories.
If required, you may order them from your specialist
stove dealer. As an alternative, a tile or stone floor is of
course very suitable.
Safety gaps (minimum gaps):
During installation of the stove it is absolutely essential
to observe the official fire protection regulations. Ask
your district heating inspector about this.
The following must be maintained as the minimum
distances from flammable or temperature-sensitive
materials (e.g. furniture, wallpaper, wooden cladding)
and from loadbearing walls. (See drawing):
A
5 cm from the back wall
B
10 cm from the side walls and
C
80 cm in the direction of radiation.

The chimney (fireplace or flue) must for example be
made of stainless steel or ceramics (glazed internally) so
that it cannot rot. This is necessary because of the low
temperature of flue gases from your pellet stove.
Standard trade flue tubes may be used for the
connection to the fireplace. Approved Flex steel flues
are also suitable.
Since excess pressure may build up at the smoke outlet
because of the way that the pellet stove works with an
induced draught fan, all fume outlet pipes as far as the
intake to the fireplace must be gas-tight. It is also
essential to ensure that the flue tube does not stick out
into the open cross-section of the chimney. The use of
wall lagging is recommended for the insertion into the
chimney. (See Figure 3).
With longer flue gas pipework, horizontal sections and
constrictions must be avoided and specially insulated
flue tubes should be used. Pipework rising in the
direction of the chimney is recommended.

External air intake:
In airtight buildings, whilst the pellet stove is operating, a
reduction in the oxygen level in the room where the
stove is installed may occur, so adequate ventilation
must be ensured. For this the pellet stove offers you the
option of operating independently of the air in the room.
To do this, connect the air intake elbow located on the
back (diameter: 57 mm) to a hose or a similar suitable
air duct. The end of the air duct must be located in the
open air or in a well-ventilated room within the building.
When installing the pellet stove in combination with
controlled residential room ventilation, the end of the air
intake duct must not be connected to the ventilation
system in an adjacent room with the air connection
system. To ensure sufficient volume of air intake, the
pipe should not be longer than about 3 m and not have
too many bends. This pipe should have a minimum
diameter of 5 cm. (The bigger, the better). If the pipe
goes to the open air, it must end with a downward
90°
bend or with wind protection. (See Figure 4).
