Prior to installing the appliance, make sure that the substructure
of the floor is suitable to bear the weight of the appliance.
Ensure that the stove is positioned horizontally and without
vibration.

Room and ambient temperatures /humidity
The appliance is suitable for rooms with normal humidity and
room temperatures ranging from +5 °C to +20 °C. Should room
temperatures fall below 5 °C, it is imperative to add appropriate
antifreeze to the water.
The appliance is not splash proof; therefore it must not be
installed in wet rooms such as bathroom units.
Basically, the appliance is dependent on indoor air, that means the air supply
needed for combustion is extracted from the room where the appliance is
positioned. Subsequently air supply is to be provided from outside by means
of a ventilation opening. To do this, an opening of 10-15 cm in diameter has to
be provided at one exterior wall of the room where the appliance is located.
Outside a stable protective grating is to be fitted. Furthermore, at places where
strong winds are prevalent or places which are exposed to weather, a protection
against wind and rain is required.
If it is not possible to provide an opening to the outside from the room where
the appliance is positioned, it is also possible to create an opening in an adjoining
room. Make sure that the adjoining room has a permanent connection
to the room where the pellet stove is positioned by means of a ventilation
grate.
If there are additional heating units in the same room, the ventilation openings
must provide adequate air supply for combustion to ensure proper operation
of all appliances!
Too low pressures in the room where the appliance is located (e.g. caused by
ventilation systems, extractor hoods etc.) or in the pellets container (e.g. caused
by pneumatic appliances) are likely to impair the functioning of the fire place and
their safety (technique) and are therefore not permitted.
Air supply connection from outside (optional equipment)
To ensure a sufficient supply of combustion air in the case of tightly sealed
windows and low-energy houses equipped with ventilation systems or when
ducted extractor hoods are used, it may be necessary to provide fresh combustion
air from outside.
Even with an outdoor air connection the requirements for an operation that is
independent from the ambient air are not fulfilled!
The dimensions for fitting are shown in „Figure 4“ as well as „Table 2“. Please
note the changes to the dimensions due to the adjustment of the height of the
appliance or of the stove frame.
• It is not allowed to install shut-off devices (flaps, dampers, …) in the air
supply line!
• The air supply line consisting of non-combustible materials must be a maximum
of 4 m in length and must not have too many bends!
• To avoid condensation, the air supply line must be insulated!
• The air flue must be at least 50 or 100 mm, respectively, in diameter. If
rectangular tubes are used, they must maintain the appropriate diameter!
• If the air supply line runs directly to the outside, it has to be protected
against wind!
• The supply of external combustion air from above may only be provided by
means of chimney systems which have been approved by us..
For the technical acceptance of the heating system, the chimney sweep is required
to check the entire installation, in particular for sufficient combustion air supply.
