A warm welcome to Contura.
A warm welcome to the Contura family. We hope you
will get a great deal of pleasure from your new stove.
As a new owner of a Contura stove, you have secured
a product with timeless design and long service life.
Contura also has a combustion process that is both
environmentally friendly and efficient, for the best heat
production.
Read through these installation instructions carefully
before installation. Read how to best light your stove
in the lighting instructions.
The stove becomes very hot
During operation, certain surfaces of the stove become
very hot and can cause burn injuries if touched. Also, take
heed of the strong heat radiated through the door glass.
Placing flammable material closer than the safe distance
indicated may cause a fire. Smoulder combustion can cause
quick gas ignition with the risk of damage to property and
personal injury.
NOTE! WARNING!
Report the installation of a stove 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.

Installation by authorised
technician
This manual contains instructions on
how the stoves must be assembled
and installed. To ensure the function
and safety of the stove, we recommend
that the installation be carried out by
an authorised technician. Contact one
of our dealers who can recommend
suitable fitters.
Building permission
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.
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 embers falling out, 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 painted metal or glass hearth plate
is available as an accessory for these
models.

For this type of connection, first remove the valance
that sits in front of the back plate's air intake.
In the case of connection through the floor, first
remove the knockout in the guide plate and any
hearth plate.
SUPPLY AIR/ACCESSORY
Supply of combustion air
When a stove is installed in a room, the air supply demand 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 approx. 25m3/h.
The connector has an external diameter of 67 mm. When installing
ducts longer 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 covered with a moisture barrier (plastic). It is important that
the lead-in, between the pipe and the wall (or floor), is sealed
using jointing compound.
A 1 m length of condensation-insulated ducting for combustion air
is available as an accessory.

Rear connection to a masonry chimney
Top connection to the chimney
Make sure that the connector
gasket does not come loose
when the connection pipe is
placed on the sleeve. If further
sealing material is required, heat-
resistant sealant may be used.
The back panel must be installed before the stove is connected at the
rear.
The hot air grille must be installed before the chimney
is connected to the top.
• The stove meets the requirements for connecting to chimneys
dimensioned for flue gas temperatures of 350°C.
• The external diameter of the connection sleeve is 150 mm.
• The stove requires a draft in the chimney of at least –12 Pa. The
draft is affected both by the length and area of the chimney, and
by how well sealed it is. The minimum recommended chimney
length is 3.5 m and suitable cross sectional area is 150-200 cm²
(140-160 mm in diameter).
• A flue with sharp bends and horizontal routing reduces the
draught in the chimney. The 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 doors must be easily accessible.
• Carefully check that the chimney is sealed and that there is no
leakage around soot doors and flue connections.

Sweeping
When sweeping, the smoke
baffle must be removed; on the
Contura 20 series this is easily
done by lifting and then pushing
the baffle to the side.
In the bag with these installation instructions
are two wing screws for the cover.

Place the stove on the
hearth plate and check
that the installation
distances are not less
than those that are given
in the figures below. The
minimum distance in
front of the stove opening
to combustible parts of
the building or interior
decoration must be at least
1 m.
When top connecting
a steel flue, please
refer to the particular
manufacturer's installation
instructions. Observe
the safety distance to
combustible material that
the steel flue requires.

The stove needs to be placed on a level and horizontal surface, so
the courses do not end up uneven and crooked. Otherwise, this can
result in abnormally large gaps and uneven lines.
During assembly, check that all tiles stand horizontally and that all
parts in a course are of a uniform height.
Remember to handle the tiles with care. They scratch easily and
the sharp edges are vulnerable to knocks. Also, take care when the
screws are to be tightened, so as not to cause cracks.
