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 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.
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.

Function check
PRIOR TO INSTALLATION
The door runners are lubricated at the factory, with
special grease that can withstand high temperatures.
This type of grease is usually difficult to find on the
market and we recommend contacting a Contura
dealer to order this special grease when lubricating
the runners.
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
Ensure that the installation meets national and regional
regulations. The installation must be approved by an authorized
inspection body.
INSTALLATION
Supply of combustion air 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 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.

Self-closing door
(ONLY APPLIES TO GERMANY)
The insert can be supplied with a self-closing door. Fold out the three tabs
on the counterweight pack. Lift out the two weights that are positioned
slightly higher up. Remove the two side panels and install the two panels
enclosed instead, see images on the next page. Check the function, if
necessary further weight can be removed. Fold in the three tabs again to
keep the counterweights in place.
Rearward 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.
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 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. Carefully check that the chimney is
sealed and that there is no leakage around soot hatches and flue
connections.
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. 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.

Service
Access to the damper and counterweight must be ensured via
doors 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 99).
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 99.
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”.
