WARNING!
The insert becomes very hot
During operation, certain surfaces of the insert 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 insert.
As a new owner of a Contura insert, 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.

FACT S
Application to local authority
Before installing a firebox 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 firebox 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.
Floor plate
Due to the risk of falling embers, a
flammable floor must be protected by a
hearth plate. It must extend at least 300
mm all the way around. The hearth plate
can consist of natural stone, concrete,
metal or glass. A glass hearth plate
is available as an accessory for these
models.

Walls behind
If your Contura i51 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
λ
must 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 to assemble and install the Contura
i51. More information about the insert
is available in the separate installation
instructions.
To ensure the function and safety of the
firebox, we recommend that installation
is carried out by an authorised
technician. Our Contura agents can
recommend a suitable installer;
information regarding our agents is
available at www.contura.eu
Instructions for lighting are also
supplied with the insert. Read them
carefully and keep them safe for
future use.

Create an opening in the top grate by using the shorter grate
profiles, see page 133. Cover the gap with a cuff.
Top connection
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 235 mm above the
connector.
Rearward connection
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 the
values obtained are presented in the Performance declaration,
external diameter of the connection is Ø150 mm.
The firebox 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 a suitable cross-sectional area is
150-200 cm
2
(Ø140-160 mm). 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.

Knockout
Supply of combustion air
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 m
3
/h.
Some installation alternatives are shown below. The air duct
connection on the stove has an external diameter of Ø100 mm.
Turn the connector to ensure an air supply!
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.

INSERT PLACEMENT
*Optional pr otective screen, see separate inst ruction
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.
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.

Final inspection of the installation
It is extremely important that the installation is inspected by an authorised inspection body
before the stove is used. Also read the "Lighting instructions" before lighting for the first time.
INSTALLING GRATE AND TOP
Adjust the rubber feet on the
disc base so that the gap up
to the steel panels is 5 mm.
