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 31.

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 m

3

/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 33.
