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 injury 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.

Removing the loose

components should be removed. When
the stove is installed reinstall the
components in reverse order.

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 fitters.
Building permission
These main insructions 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.
Floor plate
Due to the risk of falling embers, a
combustible floor must be protected by a
hearth plate which covers at least 300 mm
to the front and 100 mm along each side.
The hearth plate can consist of natural
stone, concrete, metal or glass. A painted
metal or glass hearth plate is available as
an accessory for these models.
Important to remember!

REMOVAL
How to remove the hearth surround (Vermiculite)
The heat reflecting plate must be
fitted underneath the body of the
stove if the area below is to be used
as a log-box. The heat reflector can be
removed by turning it to the left until
it slides free from the lower set of
screws holding the legs in place. The
heat reflector is hooked back in place
on the screws by turning it to the right.
Handle the vermiculite with care. Lift the smoke baffle with one hand
whilst removing the sides pieces. If necessary, move the cast-iron firebed
slightly. Reinstall in reverse order

CHIMNEY
Connection to chimney
Rear connection to a masonry chimney
Top connection to the chimney
Make sure that the connector
gasket does not work loose when
the connection pipe is placed
on the connector. If further
sealing material is required, heatresistant sealant may be used.
Connection to the chimney from the rear of the stove body is carried out
after the back plate is installed, but before the stone surround is put into
place.
When connecting the chimney to
the top of the stove body the stone
surround must be installed first.
Remember to install the hot air grille
before top connecting.
• 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 cm? (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.

SUPPLY AIR/ACCESSORY
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 approx. 25m3/h.
The connector 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
covered with a moisture inhibitor (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.
Through the external wall.
Indirect air supply through the external wall.
Through floor and foundation slab.
Through floor and wall-and-cavity
foundation.
In the back and floor plates there are
knockouts that must be removed to insert
pipes or for air supply if the stove is
equipped with a drawer, lower hatch and/or
fan (accessory).
Installation variants
Leave a 40 mm gap between
the condensation insulation
and the bottom of the stove.

* 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. Also applies to
separate glass hearth plates (accessory).
** To prevent discolouration of painted non-flammable walls we recommend that the same side distance as to combustible walls is used.
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
required by the steel flue
Installation distances
WHEN INSTALLING TURNTABLE (OPTION) the
following 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
E = height from floor to upper edge
of hatch
A separate glass hearth
plate (accessory)
increases the connection
height to the chimney
by 10 mm. The spacers
supplied with the hearth
plate are installed on the
stove before connection.
