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 combustion 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.
The stove becomes very hot
During operation, certain surfaces of the stove become
very hot and can cause burn injury if touched. Be aware
of the strong heat radiated through the hatch glass.
Placing flammable material closer than the safe distance
indicated may cause a fire. Pyre lighting can cause quick
gas ignition with the risk of damage to property and
personal injury.
NOTE! WARNING!
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
Building application
Before installing a stove
or erecting a chimney it is
necessary for you to apply
for planning permission
from your local authority.
Ask your local authority
for advice regarding
building regulations and the
application.
Hearth dimensions
The stove must be placed on a constructional heart with the
minimum dimensions shown beside, installations distances
must also be according to diagrams on next page. Check that
the building has enough bearing capacity for the heart, stove
and chimney. The stove can be loaded with maximum 100 kg of
chimney.
Chimney
Note! The stove installation and connection to a chimney must
be accomplished with the current edition of Building Regulations.
We recommend that you consult a local chimney sweep before the
installation to make sure that the chimney is in good condition.
The stove requires a draught in the chimney of at least –12
Pa. The draught is affected both by the length and area of the
chimney, and by how well sealed it is. The recommended minimum
flue length is 3.5 m and its diameter should be Ø130 to Ø150 mm.
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. 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.
