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.
NOTE:
Report the installation of a fireplace 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.
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.

FACTS
Application to local authority
Before installing a stove or erecting a
chimney, it is necessary for you to make
an application for permission to your
local authority. Ask your local authority
for advice regarding regulations and the
application.
Structural support
If the fireplace is to be positioned on
a wooden joist, a structural engineer
should evaluate the load capacity of the
floor. When the gross weight exceeds
400 kg, reinforcement of the wooden
joists is usually necessary.
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 or glass. A glass
hearth plate is available as an accessory
for these models.

Wall behind
If your Contura i41 is to be installed
against a combustible wall, the wall must
be protected by a firewall or by the
integrated protective screen which is
available as an option in some markets.
The following material requirements are
made of the firewall:
The building material must not be
combustible.
The thermal conductivity coefficient ë
may be a maximum of 0.14 W/mK. The
thickness of the building material must
always be at least 100 mm. In cases
where the building material’s insulation
properties are given as a U-Value, this
must be a maximum of 1.4 W/ m²K.
List of suitable materials:
Aerated concrete λ= 0.12-0.14
Vermiculite λ= 0.12-0.14
Calcium silicate λ= 0.09
Contact your chimney sweep for advice in
choice of other materials. Remember that
even a non-combustible wall may require
protection if it is a load bearing wall or
has combustible material behind it.
General
This manual contains instructions about
how Contura i41 must be assembled
and installed. More information about
the insert is available in the separate
installation instructions.
To ensure the function and safety of the
hearth, we recommend that installation is
carried out by an authorised technician.
Our Contura dealers can recommend
suitable technicians, information about our
dealers can be found at www.contura.eu
Instructions for lighting are also supplied
with the insert. Read them carefully and
keep them safe for future use.

SURROUND
Shims
Only handle the stone with clean hands or gloves. Handle the stone
carefully so as not to damage fragile corners and edges.
The stone is a natural material, which means that there may be
certain irregularities and variations in its appearance. Clean the
stone with a damp cloth. Soapy water can be used if necessary.
To avoid abnormally large gaps and uneven lines, it is important
that the stove and steel stand are straight and stable. Adjust and
align it carefully before hanging the stone. During assembly, check
that all the stone sections are straight and that all stones are of a
uniform height. Use shims if necessary.
After assembly is complete some adjustment of the insert feet
can improve the joint between the insert and the surround. The
internal fit of the stone can also be adjusted using the stand feet.
All feet must be contact with the base after any adjustment.

Carefully check that the chimney is sealed and that there is no
leakage around soot hatches and flue connections.
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, heat-resistant sealant may be used.
It must be possible to sweep the full length of the flue and the
soot hatches must be easily accessible.
If two fireplaces are connected to the same chimney flue,
the stove must be equipped with self-closing door, see insert
instructions.
The stove is type approved in accordance with EN 13240 and
must be connected to a chimney dimensioned for at least 350°C
the external connection diameter is Ø150 mm.
The insert 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
(Ø140-160 mm in diameter). Note that 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.
Chimney
Create an opening in the top grate by using the shorter grate
profiles, see page 275. Cover the gap with a cuff.
If a protective screen is selected, this must be installed before making
the chimney connection.
For the rearward connection it is recommended to use a 45°+ 45° angle
with soot hatch and with the centre 285 mm above the connector.

Supply rear
Supply down
To insert the combustion air hose through the floor panel,
remove the knockout.
Supply of combustion must be provided. Combustion air can
be provided directly 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. Some installation alternatives are shown to
the right. The air duct connection on the stove has an external
diameter of Ø100 mm.
In hot areas the duct should be insulated with 30 mm mineral
wool covered with a moisture inhibitor (aluminium tape). 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.

Important!
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 minimum distance to combustible parts of the
building or interior decoration in front of the stove must
be at least 1.5 m.
For placement against
combustible rear walls, a built-
in protective screen (option in
some markets), or an external
firewall that protects the wall
behind is required. Material
requirements for firewalls
according to the section “Walls
behind” on page 228.

INSERT PLACEMENT
The cross in the floor panel indicates
the location of the flue gas output.
Position the floor section and check that the minimum permitted
distance to combustible material is kept. Measure to the centre of
the floor section.
The rear edge of the floor section will align with the complete rear
edge of the surround.
If the protective screen is selected – read these
instructions before installing the insert or chimney. The stove can be positioned tight to the
wall behind.
When installing against non-vertical
walls and to facilitate installation it is
recommended that a small gap is left
between the wall and stove. Lay the floor
section a slight distance from the wall
behind, and align the position of the holes
in the ceiling for the chimney lead-in with
the same dimensions.
