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 pro-

duct with timeless design and long service life. Contura

also has a combustion process that is both environmen-

tally friendly and efficient, for the best heat production.

Read through these installation instructions carefully befo-

re 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 460. 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 460 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 start ing 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 the chimney together does not exceed 400
kg it is not normally necessary to reinforce the wooden floor 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 chimney­sweep in your area.

Chimney

The draught in the chimney must generate a neg ative 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 hatch es and flue­pipe 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.

Lay the metal template as a base-plate (see page 8) where the
stove is to stand and measure to make sure that the stove is
no closer to the wall than the minimum distances specified in
the diagrams below. A hole in the template marks the centre

of the chimney. The rear edge of the template must be flush in
line with the rear edge of the concrete surround. Allow at least

1.0 metre from the stove door to any combustible part of the
building structure or interior fittings.

Air supply

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 meth ods 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 joint ing 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.

Making a hole through the ceiling

When drawing a flue from the top of the stove to a steel
chimney, you need to make a hole through the ceiling. Ensure
that the centre of the hole is directly above the mark on the
base-plate (the floor template) that indicates the centre of
the chimney. For chimney installation, please refer to the
installation instructions supplied with the chimney.
At this stage fit only the rear section of the ceiling insulation. It
is important that the ceiling insulation plate is centred over the
hole in the ceiling.

Installing the C-460 wall protection panel

Screw the outer steel profiles to the wall 1200 mm apart.
Ensure that they are absolutely perpendicular. Place the air
holes by the floor and ceiling. The two profiles are 2500 mm
long. If the ceiling is lower, use a hacksaw or metal shears to cut
the profiles to the appropriate height. To make this easier, there
is a die-cut slot 100 mm from the end (see illustration). Place
the two remaining profiles between the outer ones.
Cut the minerit boards to the desired width. Position the minerit
boards edge to edge with a bead of acrylic sealant in the gap
and screw them into place with the supplied screws. Do not
install the upper board until the rear section of the headlining
seal has been installed.

Positioning the base-plate

The metal template indicates the position of the stove body, the
concrete surround and the hole in the ceiling for the flue. The
rear edge of the surround will later be aligned exactly with the
rear edge of the template.
Place the base-plate on the floor – after first ensuring that
you have observed all the requisite safety distances (see page

3) – so that the hole in the plate that marks the centre of the
chimney is at the required distance from the wall. If a wall
protection panel is to be installed, the template is fitted against
the panel.
Screw the base-plate to the floor.

Assembling the concrete surround

Before starting the assembly work, check to make sure that none of the concrete
components have any hairline cracks that run all the way through. When assembling
the surround, use the cement supplied to bond the sections together. Mix 1 part
water with 2 parts cement. It is impor tant that the various components are
assembled so that the finished construction is straight and true, both horizontally
and vertically. Placing the cement in little heaps rather than spreading it out as a
bed of cement makes it easier to ensure that the construction is horizontal. For the
best adhesion, it is advisable to wet surfaces that are to be joined. The cement bed
should be 1–2 mm thick when the sections have been assembled and any surplus
cement has been pressed out.

The supplied silicone is used to secure the marble
shelves and to attach the concrete sections to the
rear wall. When sealing the joint to the rear wall, only
the paint-over acrylic sealant must be used.

The silicone can also be used to repair any slight
unevenness in the concrete blocks and any minor
damage.

When the fire is lit, the metal in the fire-box
expands, so it is absolutely essential that the
concrete surround does not come into contact with
the stove body. Check that there is a gap of at least
2-3 mm between the stove body and the surround.

Place the plinth on the base-plate. The rear edge of the plinth
must be flush with the rear edge of the base-plate.
Simply stand the filler-piece for the plint h loose in place, or
squeeze out a few small blobs of acrylic sealant to keep it from
moving. Note, however, that it must be possible to remove the
filler-piece when cleaning the stove or servicing the fan.

If a fan is to be connected, make holes for the
cables either in the wall or in the back of the plinth.

Draw the cables through the hole before securing
the plinth to the base-plate.

The gap between the rebate in the concrete components and
the rear panel must be carefully sealed with silicone. This is
necessary to prevent the wrong kind of convection currents in
the warm air. Squeeze out a liberal amount of silicone all along
the edge of the rear panel. Any surplus pressed out when the
con crete sections are fitted can be smoothed by hand if you
first dip your finger in soapy water.

held in place firmly against the ceiling. Hold the rubber sealing strip so that the gills are facing the flue casing and press the strip into place
in the gap around the chimney. Seal and use insulating blocks to insulate in the roof/floor above the ceiling insulation.

LEK

Lay the first insulating block on top of the sealing plate. Make
sure that the insulation forms a tight seal around the flue base
(the start section of the flue) and the concrete surround. Then fit
the second insulating block in place. This has a larger hole in the
middle and should form a tight seal with the outside of the chimney
module. Fit the bottom chimney module into place.

work, clean the profiles with mineral spirits or a similar kind of
solvent.
When the cement and the acrylic sealant have dried, paint the
entire concrete surround and the wall-protection panels with a
textured coating. Allow the paint to dry for 24 hours and then
go over the painted areas with a latex paint (gloss 07). Take
precautions to protect the stove body against paint splashes.

Wait for the cement to dry for at
least one week before lighting a
fire in the stove.

LEK

Use the adhesive to fill the gaps between the different sections of
the chimney hood, adding pieces of fibre-glass tape to reinforce
the seal. The adhesive should also be used to fill the gap between
the hood and the marble slabs of the shelf. The gap between
the concrete surround and the marble shelf is filled with acrylic
sealant.

LEK

The grilles are simply placed loose over the air vents. Before fitting
the metal floor-plate (optional accessory) around the stove plinth,
cut away the inside section and smooth off any jagged edges or

How to use the stove

Under normal conditions we recommend that the stove burns 2
kg of wood per hour. The maximum permissible amount is 3.5 kg
per hour. Most types of wood can be used: deciduous (broad-leaf)
woods are preferable, as they generally burn more calmly. It is
important that the wood is dry and that logs are of a suitable size:
about 25–35 cm long and 7–9 cm in diameter. Always open and
close the door slowly and carefully to prevent the sudden changes
in pressure inside the stove which otherwise can cause a back­draught of smoke in the room.

1. Open the air supply control by moving the damper
spindle to the right.

2. Place newspaper or a firelighter in the fire-box. Then

stack about 3–3.5 kg of fine-split logs on the fire-bed,
laid in a criss-cross pattern as shown.

3. Light the fire.

4. Push the door to, but do not close it until the fire is

burning well (after about 10–15 minutes).

5. When the first pile of logs has burnt down, stoke up the

fire again by placing 3 or 4 logs (weighing 2–2.5 kg in all)
on the embers.

Pulling out the damper bar opens the grate disc. This should only
be done for a short time when lighting or re-stoking the fire to
ensure that the wood catches light quickly, and when riddling the
ash into the ash pan. If the grate is left open for a long time, the
stove and the chimney may be damaged as a result of the excessive
heat.

Important!

It is essential that the wood starts to burn quickly. Smouldering
produces excessive amounts of smoke and may, in exceptional
circumstances, cause the fumes produced to ignite spontaneously
and damage the stove. You can get the logs to burn quickly by
opening the grate disc for a short while after re-stoking the fire,
or by leaving the door ajar until the wood is burning.

Please read the separate Lighting and
Maintenance Instructions carefully before
lighting the stove for the first time.
