WARNING!
The insert becomes very hot
Parts of the insert become very hot when it is in use and
can cause burns if touched. You should also be careful
of the heat that transfers through the door glass.
Combustible materials must be kept at the stated safe
distance to prevent the risk of fire. A smouldering fire
emits gases that can suddenly ignite and cause material
damage and personal injury.
NB!
You are required to apply to your local
authority for permission to install a
fireplace/stove.
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 of the installation, as this will affect the routines
for regular chimney-sweeping services.
A warm welcome to Contura.
Welcome to the Contura family. We hope you will
get a great deal of pleasure from your new insert.
Congratulations on your purchase of a Contura insert.
You have acquired a reliable quality product with a
timeless design and long service life. Contura produces
environmentally-friendly wood burning stoves that create
heat in the most efficient way possible.
Please read these instructions carefully and thoroughly
before installation. The Lighting instructions explain how
you can obtain optimal performance from your stove.

Hearth plate
To protect the floor in front of the hearth
from falling embers, a non-combustible
floor covering must be placed at least 300
mm all around. A toughened glass hearth
plate is available as an accessory.
Application to local authority
You must apply for permission from your
local authority before installing a stove or
erecting a chimney. We recommend you
contact your local authority for advice and
information about obtaining permission.
General information
This manual contains instructions on how
to install the Contura i50. We recommend
the insert be installed by a qualified
tradesperson to ensure it functions safely
and properly. Our Contura dealers can
recommend suitable installers. Dealer
information is available at www.contura.eu
An instruction manual on how to obtain
optimal performance from your insert is
also provided. Please read this carefully
and keep for future reference.
Structural support
Check that the floor joists are strong
enough to bear the weight of the insert,
chimney and construction parts.

PRIOR TO INSTALLATION
Heat deflector
Install the heat deflector according to
separate instructions.
Note that Contura’s protective screen is
used instead of the heat deflector for all
Ci51 installations.
For installation in the UK and in
smoke control areas
The Contura i50 and i51, 8 kW woodburning stoves has been
recommended as suitable for use in smoke control areas. This
when burning wood logs and operated in accordance with these
instructions and when fitted with a permanent stop to prevent
closure of primary air control beyond the 52 mm² open position,
secondary air control beyond the 500 mm² open position and the
tertiary air control beyond the 215 mm² open position.
Mandatory for smoke control areas
The permanent stop must be installed if the appliance is to be
used in a smoke control area, this stop must not be removed in
smoke control areas, otherwise an offence will be committed if
the appliance is used without the permanent stop in place.

Installation
Combustion air supply
Supply of combustion must be provided. Combustion air can be
drawn 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 below. The connection
sleeve on the stove has an external diameter of Ø100 mm.
In warm spaces, the duct should be insulated to prevent
condensation using 30 mm mineral wool covered with a vapour
barrier (aluminium tape). It is important that the lead-in,
between the pipe and the wall (or floor), is sealed using jointing
compound.
A 1-metre combustion-air tube insulated to prevent
condensation is available as an optional extra.
Make sure that the installation complies with national and
regional regulations. The installation must be approved by an
authorised inspector.

Self-closing door
(ONLY APPLIES TO GERMANY)
Rear connection
If connecting at the rear, we recommend using
a 45°+45° angle with a soot hatch and with the
centre 235 mm above the sleeve.
It is important that sweeping can be carried
out through convection grates or a hatch in the
surround.
Chimney
CHIMNEY/SELF-CLOSING DOOR
The insert is approved for connection to a chimney designed to
withstand flue gas temperatures of up to 350°C. The external
diameter of the connection sleeve is Ø150 mm.
The insert requires a draft in the chimney of at least –12 Pa. The
draft is affected primarily by the length and area of the chimney
and also by how well sealed it is. The minimum recommended
chimney length is 3.5 m and a suitable cross-section area is
150-200 cm2 (Ø140-160 mm). Carefully check that the chimney is
sealed and that there is no leakage of smoke from the soot doors
or connections.
Note that sharp bends and horizontal lengths in a flue pipe reduce
the draft in the chimney. The maximum horizontal length of flue
pipe allowed is 1 m, provided the flue pipe rises vertically for at
least 5 m. It must be possible to sweep the full length of the flue,
and the soot doors must be easily accessible.
If two fireplaces are connected to the same chimney flue, the
stove must be fitted with a self-closing door.

Service
Make sure it is possible to access the damper control and
counterweight through hatches or ventilation grilles in the surround.
RECESSING THE INSERT
Convection air
Sealing
The recess must not go all the way up to the ceiling, leave an air
gap of at least 20 mm closest to the ceiling. The recess must be
sealed off above the convection exhaust. The seal must be 100
mm above the convection exhaust’s upper edge and must be made
of 100 mm non-flammable material according to the material
requirements above. Use heat-resistant silicone, for example,
between the seal and chimney.
The building material must not be combustible.
The thermal conductivity coefficient λmust 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.
Material requirements
The convection air ventilates the surround, cools the insert and
transports the hot air out into the room. The effective cross
section area on the air intake and exhaust must not be less than
the stated values. The air intake must be positioned somewhere
between floor level and the bottom of the insert, at the front or
on the sides of the recess. The vent must be positioned above the
insert’s highest point at the front or to the sides of the recess.
If the air intake respectively the vent is positioned on the sides,
the areas for the left respectively right sides must be the same
size to ensure that the insert is evenly cooled.
The distance from the exhausts on the sides to the combustible
wall behind must be 100 mm.
Observe the minimum distance up to the ceiling (see diagram on
page 97).
Convection air in: 600 cm²
Convection air out: 600 cm²
If the convection outlets are directed upwards the following
applies
- the recess must be free-standing or placed against a
non-combustible wall.
- the distance from the air outlet to combustible roof must be at
least 750 mm.
When recessing the insert, adjacent walls that are not classed
as fire walls or are considered unsuitable for heat loads must
be protected by non-combustible material according to the
specification below.
All joints on the non-combustible material must be sealed using
the manufacture’s recommended method. The area between
the insert and the recess must be ventilated according to the
specification/dimension diagrams on page 97.
When 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 Heat
radiation from the door is strong and because of this combustible
material must not be placed closer than 1.5 m in front of the door.
When recessing, building material must not be in direct contact
with the insert due to the thermal expansion of the insert.
Note that building regulations apply regarding the area below and
in front of the insert, see section ”Hearth plate”.

Final inspection of the installation
It is extremely important that the installation is inspected by an authorised inspection body
before the stove is used. You should also read the “Lighting instructions” before lighting the stove
for the first time.
RECESSING THE INSERT
* The distance between the exhausts on
the sides and a combustible wall behind
should be at least 100 mm.
