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.
Contura reserves the right to change dimensions and procedures specified in these instructions
at any time without notice. Access the latest version at www.contura.eu

Installation by a licensed
professional
This manual contains instructions on how to
assemble and install the insert. We recommend
the insert be installed by a qualified tradesperson
to ensure it functions safely and properly.
Contact one of our dealers who can recommend
professional installers.

Planning permission

You must apply for planning permission from
your local authority before installing a stove or
erecting a chimney. We recommend you contact
your local authority for advice and information on
planning permission.

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.
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
plate or glass. A glass hearth plate is available as
an accessory for these models.
Final inspection of the
installation
When it has been installed, the insert must be
inspected by a licensed chimney sweep before it
can be used. You should also read the "Lighting
instructions" before lighting the stove for the
first time.

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 (optional accessory).
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:
λ = 0.12-0.14
Aerated concrete
λ = 0.12-0.14
Vermiculite
λ = 0.09
Calcium silicate
Products with an integrated protective
screen can be installed in front of a wall
with a minimum U-value of 0.08 W/(m²K).
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.
