How to use the stove 15
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.

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
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.

General information
This folder contains instructions on how to assemble and install
stoves in the Contura 450. To guarantee the function and safety
of the stove we recommend that it is installed by a professional.
Our Handöl agents can recommend a suitable installer. 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.
The stove meets with the requirements which allow it to be
connected to a chimney with 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.

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. The amount of combustion
air used for combustion is approximately 25 m³/h.
The drawings below show a number of ways in which the stove
can be supplied 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 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 is flat, the hole in the ceiling must measure
380x380 mm in size and be cut so that it emulates the angle of
the stove, both for installations against a straight wall and in
corners.
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
parallel to the walls.

Fit the flue-base (the start-section of flue pipe) to the connecting
sleeve on the stove. Make sure that the seal 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.

Assemble one or more chimney modules before fitting the
chimney hood into place. Lift the chimney hood up into the
chimney shaft and then slide it gently down into place over the
guides on the stove. Make sure that the insulating panel forms
a good seal around the chimney hood and prevents hot air from
rising up to the ceiling.

Check the height to make sure that the hole aligns with the
chimney connection on the rear of the stove. Leave the mortar
to dry before connecting the stove to the flue.
Slide the connecting flue over the collar. Make sure that
the seal round the collar is not dislodged. If further sealing
material is required, heat-resistant sealant may be used.

Under normal conditions we recommend that the stove burns
2–2.5 kg of wood per hour. The maximum permissible amount
is 3–3.5 kg per hour. Most types of wood can be used, but wood
from deciduous (broad-leaf) trees is preferable, as this generally
burns more evenly. 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 back-draught 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. Re-stoke the fire with 3 logs weighing about 2–2.5 kg in all.
Lay the first two diagonally over the embers and the third
one at an angle across the other two. To make sure the logs
catch fire quickly, leave the door slightly ajar until the logs are
blazing.
6. If you prefer your fire to burn more slowly, reduce the supply
of air to about half. Make sure,
however, that the fire burns with bright, flickering flames.
Pulling out the damper bar opens the grate disc. It is only
necessary to do this 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 open until the wood is
burning.
Important
Read through the separate instructions carefully before
lighting the stove for the first time.
