NOTE!
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.
WARNING!
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.
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.

Technical details Important to remember!
FACTS
Installation by authorised
technician
This manual contains instructions about
how the stove 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 fitters.
Building permission
Before installing a stove or erecting a
chimney, it is necessary for you to make an
application for building permission to your
local authority. Ask your local authority for
advice regarding building regulations and
the application.
Structural support
The wall must be strong enough to bear the
weight of the stove and chimney.
Floor 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 painted metal
or glass hearth plate is available as an
accessory for these models.
If the stove needs to be put down
to be moved or if the pillar foot is
to be installed, remove any loose
components. This is described at the
end of these installation instructions.

• The stove meets the requirements for connecting to chimneys
dimensioned for 350°C flue gas temperature.
• 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. 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. 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.
Rear connection to a masonry chimney
The back panel must be installed before the stove is rear
connected.

INSTALLATION DISTANCE / SUPPLY
** To prevent discolouration of painted non-flammable walls we recommend that the same side distance as to combustible walls is used.
*** Example of an approved firewall is 120 mm solid brick with the following values: (Thermal conductivity (λ) = 0.6-0.7 W/m *K, Density = 1500-1700 kg/m³, as well as Specific heat capacity (c) =
840 J/kg *K).
Indirect air supply through the external wall
Supply of combustion air
Combustion air can be supplied via a duct from outside, or
indirectly via a vent in the outer wall of the room where the stove is
placed. The amount of combustion air that is used for combustion
is approx. 25 m3/h.

ASSEMBLY
Installing of C 850W
Insert the connection pipe into the wall
connector towards the folded tabs.
Position the back plate opposite the connector. Check that the back plate is vertical and
mark the mounting holes that you intend to use. Choose a hole so that it ends up as far
away from any mortar joints as possible. Predrill the hole with an 8 mm masonry drill, the
hole must be at least 80 mm deep. Clean the hole thoroughly and secure the back plate to
the chimney breast with the 6 masonry screws supplied. Screws that do not engage must
be considered ineffective and moved to another hole.
