Installation by authorised
technician
This manual contains instructions about how
the stoves must be assembled and installed.
To ensure the function and safety of the stove,
we recommend that the installation is carried
out by an authorised technician. Contact one
of our dealers who can recommend suitable
technicians.
Building application
These main instructions may give guidance
which would contravene national building
regulations. Please refer to supplementary
instructions or ask your local authority for
advice regarding building regulations.
Before installing a stove or erecting a chimney
it is necessary for you to make a building
application permission to your local authority.
The owner of the house is personally
responsible for ensuring compliance with the
mandatory safety requirements and must
have the installation approved by a qualified
inspector. Your local chimney sweep must
also be informed about the installation as this
will affect the routines for regular chimney-
sweeping services.
Structural support
Check that the wood joists are strong enough
to bear the weight of the stove and chimney.
The stove and chimney can usually be placed
on a normal wooden joist in a single occupancy
house if the total weight does not exceed
400 kg.
Hearth plate
Due to the risk of falling embers, a flammable
floor must be protected by a hearth plate. It
must extend 300 mm in front of the stove and
100 mm on each side of the stove, or have a
200 mm extension on each side of the opening.
The hearth plate can consist of natural stone,
concrete, metal plate or glass. A glass hearth
plate is available as an accessory for these
models.
Final inspection of the
installation
It is extremely important that the installation
is inspected by an authorised chimney sweep
before the stove is used. Also read the
”Lighting instructions”, before lighting for the
first time.

The stove becomes very hot
During operation, certain surfaces of the
stove become very hot and can cause
burn injury if touched. Be aware of the
strong heat radiated through the hatch
glass. Placing flammable material closer
than the safe distance indicated may
cause a fire. Pyre lighting can cause quick
gas ignition with the risk of damage to
property and personal injury.
Connection to chimney
• The stove must be connected to chimneys dimensioned for a minimum flue
gas temperature of 400°C.
• The external diameter of the connection sleeve is 150 mm.
• Normal chimney draw under nominal operation should be between 20-25
Pa close to the connector. The draft is affected both by the length and
area of the chimney, and by how well sealed it is. Minimum recommended
chimney length is 3.5 m and suitable cross section area is 150-200 cm²
(140-160 mm in diameter).
• A flue with sharp bends and horizontal routing reduces the draught in
the chimney. Maximum horizontal flue is 1 m, on the condition that the
vertical flue length is at least 5 m.
• It must be possible to sweep the full length of the flue and the soot
hatches must be easily accessible.
• Carefully check that the chimney is sealed and that there is no leakage
around soot hatches and flue connections. See page 40.
Supply of combustion air
When a stove is installed in a room, the demand for air supply to the room
increases. Air can be provided indirectly via a vent in the outer wall or via a
duct from the outside that is connected to the connector on the underneath
of the stove. The amount of air needed for combustion is 15 m3/h.
The connector for the combustion air has an external diameter of 67 mm.
When duct routing further than 1 m the pipe diameter must be increased to
100 mm and a correspondingly larger wall vent must be selected.
In hot areas, the duct should be insulated with 30 mm mineral wool with a
moisture inhibiting outer cover. It is also important to seal around the hole
in the wall (or floor) of the lead-in using sealant.
A 1 m length of condensation insulated ducting for combustion air is
available as an accessory. See page 42.

The minimum distance in front of
the stove opening to combustible
parts of the building or interior
decoration must be at least 1,2 m.
The dimension diagrams only
show the minimum permitted
installation distances for the
stove. When connecting to a steel
flue, also note the safety distance
requirements of the flue. The
safety distance between an un-
insulated flue and a combustible
part of the building should be at
least 450 mm.
Installation distances
WHEN INSTALLING TURNTABLE (OPTION) the follow-
ing installation distances do not apply.
See the separate turntable installation instructions.
A = height from floor to chimney
connection upwards
B = height from floor to c/c chimney
connection rear
C = height from floor to air inlet
D = height from floor to lower edge
of hatch
A separate glass hearth
plate (accessory)
increases the connection
height to the chimney by
10 mm.
Permitted area for
combustible parts
of the building
* If the stove is placed on a hearth plate made of glass for example (accessory), the height from the floor is affected by a distance corresponding to the thickness of the hearth plate, for a free standing
glass hearth plate this is 10 mm.
** To prevent discolouration of painted non-flammable walls we recommend that the same side distance as to combustible walls is used.
