How to use the stove 97
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.
WARNING!
The stove becomes very hot
During operation, certain surfaces of the stove become
very hot and can cause burn injury 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.

General information
This folder contains instructions on how to assemble and
install stoves in the Contura 470. The stove also comes with
comprehensive Lighting and Maintenance Instructions. Please
take time to read all this information carefully and keep it in a
safe place for future reference.
Contura 470 stoves have been type-approved in Sweden
for connection to a chimney which can withstand flue gas
temperatures of 350 °C. The connecting sleeve has an external
diameter of 150 mm.
To ensure proper combustion, sufficient air must be supplied to
the stove from outdoors.
Building permission
It may be necessary for you to apply for building permission
from your local planning authority before installing a stove or
erecting a chimney. Before starting installation work, make sure
that you check which regulations apply.
Structural support
Check to make sure that the floor is strong enough to support
the weight of the stove and chimney. If you intend to locate the
stove on standard wooden floor joists, contact a professional
builder to make sure that the construction will withstand the
load. If the total weight of the stove and chimney together does
not exceed 400 kilos, it is not usually necessary to reinforce the
joists.
Floor plate
To protect the floor from sparks and falling embers the stove
must stand on a non-combustible surface which extends at
least 300 mm in front of the stove and 100 mm along each
side. As other statutory requirements apply in some countries,
we recommend that you consult the relevant authority or an
authorised chimney-sweep in your area.
Chimney
The draught in the chimney must generate a negative pressure
of at least 12 Pa. The draught is affected both by the length and
cross-sectional area of the chimney, and by how well sealed the
construction is. The shortest recommended chimney length is
3.5 metres. The cross-sectional area of the chimney must be
approximately 150–200 cm² (140–160 mm in diameter).
Make sure that there are no gaps around soot hatches and flue-
pipe connections.
Remember that the draught is reduced in flues with sharp bends
or horizontal sections. A horizontal flue length of up to 1.0
metre is permissible, provided that the vertical flue is at least
5.0 metres in height.
It must be possible to clean the flue throughout its entire
length, and the soot hatches must be easily accessible.

Stand the stove on a floor plate which meets the requirements
laid down on page 76. Measure to make sure that the size of
the floor plate and the distance between the stove and the wall
are at least as great as specified in the diagrams below. Allow at
least 1.0 metre from the stove door to any combustible part of
the building structure or interior fittings.
Important!
When placing the stove in a corner close to combustible
wall materials or against a wall with a gap of only 305 mm
to combustible materials, an extra side window with a heat-
reflecting surface must always be fitted.

Combustion air for the stove can be supplied through a duct
directly from outside, or indirectly through a vent in the wall of
the room where the stove is installed. Flexible tubing is available
as an accessory.
The drawings below show various alternative methods of
supplying the stove with air.
The air duct connection on the stove has an external diameter of
64 mm.
Important!
To prevent condensation in air ducts which pass through heated
areas, the duct must be insulated with 30 mm of mineral wool
covered with aluminium tape.
It is important to seal carefully around the duct where it passes
through the wall or floor. Use jointing compound. For ducts longer
than 1.0 metre, the diameter must be increased to 100 mm, and
the size of the air vent increased correspondingly.

When connecting the stove to a steel chimney, always refer to the
installation instructions supplied by the chimney manufacturer. The
size of the hole in the ceiling through which the chimney passes
must be adapted to the dimensions of the chimney shaft itself
and to the mandatory “safe distances” to combustible materials
in each individual instance. The sketches below show the required
gap between the chimney and any combustible material. The stove
can support a maximum chimney weight of 250 kilos. However, we
strongly recommend that you check with the building and planning
department of your local authority to make sure that local building
regulations permit a steel chimney to rest on a stove.

When the ceiling slopes and the stove is placed in a corner, the
hole in the ceiling must measure 440x440 mm in size and be cut

round the collar is not dislodged. If further sealing material is required,
heat-resistant sealant may be used.
When using a Premodul chimney system, attach the sealing plate and
insulating panel to the start pipe. Cut out the knockout from the sealing
plate and fold the four tabs down slightly. Move the upper start pipe down
through the sealing plate with all four tabs trailing against the outside of
the pipe. Insert the upper start pipe down in the start pipe and check that
the four tabs are against the outside of the upper start pipe and on the
upper edge of the start pipe (see enlarged image). Install the insulating
panel, stop washer, transitional insulation and chimney module.
For different chimney systems, the sealing plate can be screwed to the
rear panel and the insulating panel laid on top.

Important!
If you connect the stove to a rear flue, but wish to install an extra layer of soapstone tiles reaching right up to a ceiling made of
combustible material, please note the following:
• This is a special, customised solution, so the extra layer of chimney tiles and the chimney frame will have to be cut to size on site.
• The elbow joint must be insulated with an extra 60 mm of mineral wool (not supplied.)
• To ensure the right ventilation, there must be a gap of at least 200 mm between the ceiling and the top of the rear panel of the chimney
(the top section of the rear panel must be removed, or cut to size on site).
• There must be a gap of at least 5 mm between the soapstone tiles and the ceiling to allow for an expansion in the length of the chimney
during heating.

Adjust the height of the entire hood by turning all of the adjusting

making the adjustment, all the locknuts on the top must be loose
with a certain amount of play. Adjust the measurement so that
the height between the bottom edge of the left and right-hand
hood sides and the top edge of the guides is 383 mm on both
sides. Make sure that the measurements on page 90 are correctly
adjusted and check them in accordance with the instructions on
page 84. Tighten the locknuts on the top. There may be slight
variations between the sides if the chimney frame is not exactly
perpendicular. There should be a 10 mm gap between the top of
the door and the hood-front base.
