USER MANUAL FOR STOVES WITHOUT BOILERS
SUPPLEMENTARY INSTALLATION INSTRUCTIONS FOR THE UK MARKET
TO BE READ IN CONJUNCTION WITH THOSE IN THE INSTRUCTION BOOKLET
READ THE INSTRUCTION BOOKLET AND THESE SUPPLEMENTARY INSTRUC-
TIONS CAREFULLY BEFORE INSTALLATION
These instructions together with those in the instruction booklet cover the basic principles to ensure the
satisfactory installation of the stove, although detail may need slight modification to suit particular local site
conditions.
In all cases the installation must comply with current Building Regulations, Local Authority Byelaws and other
specifications or regulations as they affect the installation of the stove.
It should be noted that the Building Regulations requirements may be met by adopting the relevant recom-
mendations given in British Standards BS 8303, BS EN 15287-1:2007 as an alternative means to achieve an
equivalent level of performance to that obtained following the guidance given in Approved Document J.
Should any conflict apply between these instructions and the original manufacturers instructions then the
most stringent advice must apply.
Please note that it is a legal requirement under England and Wales Building Regulations that the installation
of the stove is either carried out under Local Authority Building Control approval or is installed by a Competent
Person registered with a Government approved Competent Persons Scheme. HETAS Ltd operate such a Scheme
and a listing of their Registered Competent Persons can be found on their website at www.hetas.co.uk.
CO Alarms:-
Building regulations require that when ever a new or replacement fixed solid fuel or wood/biomass appliance is
installed in a dwelling a carbon monoxide alarm must be fitted in the same room as the appliance. Further gui-
dance on the installation of the carbon monoxide alarm is available in BS EN 50292:2002 and from the alarm
manufacturer’s instructions. Provision of an alarm must not be considered a substitute for either installing
the appliance correctly or ensuring regular servicing and maintenance of the appliance and chimney system.
811142 BAV GB-7 March 2014

HEALTH AND SAFETY PRECAUTIONS
Special care must be taken when installing the stove such that the requirements of the Health and Safety at Work
Act are met.
Handling
Adequate facilities must be available for loading, unloading and site handling.
Fire Cement
Some types of fire cement are caustic and should not be allowed to come into contact with the skin. In case of
contact wash immediately with plenty of water.
Asbestos
This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the course of installation then
please seek specialist guidance and use appropriate protective equipment.
Metal Parts
When installing or servicing this stove care should be taken to avoid the possibility of personal injury.
STOVE PERFORMANCE
Refer to the manufacturer’s main instruction manual for details of the stove’s performance.
PREPARATORY WORK AND SAFETY CHECKS
IMPORTANT WARNING
This stove must not be installed into a chimney that serves any other heating appliance.
There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emit fumes
into the room.
811142 BAV GB-7 March 2014

Chimney
In order for the stove to perform satisfactorily the chimney height must be sufficient to ensure an adequate
draught of approximately 15 Pa so as to clear the products of combustion and prevent smoke problems into the
room.
NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet of the stove to the top of
the chimney should be satisfactory. Alternatively the calculation procedure given in EN 13384-1 may be used as the
basis for deciding whether a particular chimney design will provide sufficient draught. BS EN 15287-1:2007 gives
additional details.
The outlet from the chimney should be above the roof of the building in accordance with the provisions of Building
Regulations Approved Document J.
If installation is into an existing chimney then it must be sound and have no cracks or other faults which might allow
fumes into the house. Older properties, especially, may have chimney faults or the cross section may be too large
i.e. more than 230 mm x 230 mm. Remedial action should be taken, if required, seeking expert advice, if necessary.
If it is found necessary to line the chimney then a flue liner suitable for solid fuel must be used in accordance with
Building Regulations Approved Document J.
Any existing chimney must be clear of obstruction and have been swept clean immediately before installation of the
stove. If the stove is fitted in place of an open fire then the chimney should be swept one month after installation to
clear any soot falls which may have occurred due to the difference in combustion between the stove and the open
fire.
If there is no existing chimney then any new system must be to the designation described above and in accordance
with Building Regulations Approved Document J.
A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not suitable for use as the com-
plete chimney. The chimney and connecting fluepipe must have a minimum diameter of 150 mm and its dimension
should be not less than the size of the outlet socket of the stove.
Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends should not be used.
811142 BAV GB-7 March 2014

Combustible material should not be located where the heat dissipating through the walls of fireplaces or flues could
ignite it. Therefore when installing the stove in the presence of combustible materials due account must be taken of
the guidance on the separation of combustible material given in Building Regulations Approved Document J and also
in these stove instructions.
If it is found that there is excessive draught in the chimney then a draught stabiliser should be fitted. Fitting of a
draught stabiliser will affect the requirement for the permanent air supply into the room in which the stove is fitted
in accordance with Approved Document J (see also combustion air supply).
Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping the chimney and con-
necting fluepipe where it is not intended for the chimney to be swept through the appliance.
Hearth
The hearth should be level and able to accommodate the weight of the stove and its chimney if the chimney is not
independently supported. The weight of the stove is indicated in the brochure.
The stove should preferably be installed on a non-combustible hearth of a size and construction that is in accor-
dance with the provisions of the current Building Regulations Approved Document J.
The clearance distances to combustible material beneath, surrounding or upon the hearth and walls adjacent to the
hearth should comply with the guidance on the separation of combustible material given in Building Regulations
Approved Document J and also in these stove instructions.
If the stove is to be installed on a combustible floor surface, it must be covered with a non-combustible material at
least 12mm thick, in accordance with Building Regulations Approved Document J, to a distance of 30 cm in front of
the stove and 15 cm to each side measuring from the door of the combustion chamber.
811142 BAV GB-7 March 2014

Combustion air supply
In order for the stove to perform efficiently and safely there must be an adequate air supply into the room in which
the stove is installed to provide combustion air. The provision of air supply to the stove must be in accordance with
current Building Regulations Approved Document J. Special attention should be taken in newer build properties
where the design air permeability is less than 5m3/h.m2. Approved Document J gives more information on this. An
opening window is not appropriate for this purpose.
The fitting of an external air kit direct to outside air must not be considered substitute for installing the appli-
ance with a permanently open air vent in compliance with ventilation requirements stated in Approved Document
J. Please reference ADJ for further guidance.
Connection to chimney
Stoves may have a choice of either a rear or top flue gas connector that allows connection to either a masonry chim-
ney or a prefabricated factory made insulated metal chimney in accordance with their instructions. In some cases
it may be necessary to fit an adaptor to increase the diameter of the flue to the minimum required 150 mm section
of the chimney or liner. All joints in the connection between the stove and the chimney must be made gastight using
fire cement and where necessary fire-proof rope infill. Means should be made for sweeping the entire length of the
flue, be that through the appliance or by suitable sweeping hatch in the flue.
Commissioning and handover
Ensure all parts are fitted in accordance with the instructions.
On completion of the installation allow a suitable period of time for any fire cement and mortar to dry out, before
lighting the stove. Once the stove is under fire check all seals for soundness and check that the flue is functioning
correctly and that all products of combustion are vented safely to atmosphere via the chimney terminal.
On completion of the installation and commissioning ensure that the operating instructions for the stove are left
with the customer. Ensure to advise the customer on the correct use of the appliance and warn them to use only the
recommended fuel for the stove.
Advise the user what to do should smoke or fumes be emitted from the stove. The customer should be warned to use
a fireguard to BS 8423:2002 (Replaces BS 6539) in the presence of children, aged and/or infirm persons.
811142 BAV GB-7 March 2014

HETAS Ltd Approval;
These appliances have been approved by HETAS Ltd as an intermittent operating appliance for burning wood logs
only.
WARNING NOTE
Properly installed, operated and maintained this stove will not emit fumes into the dwelling. Occasional fumes from
de ashing and re fuelling may occur. However, persistent fume emission is potentially dangerous and must not be
tolerated. If fume emission does persist, then the following immediate action should be taken:
(a) Open doors and windows to ventilate the room and then leave the premises.
(b) Let the fire go out.
(c) Check for flue or chimney blockage and clean if required
(d) Do not attempt to relight the fire until the cause of the fume emission has been identified and corrected.
If necessary seek expert advice.
The most common cause of fume emission is flueway or chimney blockage. For your own safety these must be kept
clean at all times.
IMPORTANT NOTES
General
Before lighting the stove check with the installer that the installation work and commissioning checks described
above have been carried out correctly and that the chimney has been swept clean, is sound and free from any
obstructions. As part of the stoves’ commissioning and handover the installer should have shown you how to operate
the stove correctly.
811142 BAV GB-7 March 2014

CO Alarm
Your installer should have fitted a CO alarm in the same room as the appliance. If the alarm sounds unexpectedly,
follow the instructions given under “Warning Note” above.
Air Controls
Manually operated air control can be managed by adjusting the air control valve to increase/decrease the air flow to
the stove.
Use of fireguard
When using the stove in situations where children, aged and/or infirm persons are present a fireguard must be
used to prevent accidental contact with the stove. The fireguard should be manufactured in accordance with BS
8423:2002.
Chimney cleaning
The chimney should be swept at least twice a year. It is important that the flue connection and chimney are swept
prior to lighting up after a prolonged shutdown period.
If the stove is fitted in place of an open fire then the chimney will require sweeping after a month of continuous
operation. This is a precaution to ensure that any “softer” deposits left from the open fire usage have not been
loosened by the higher flue temperatures generated by the closed stove.
In situations where it is not possible to sweep through the stove the installer will have provided alternative means,
such as a soot door. After sweeping the chimney the stove flue outlet and the flue pipe connecting the stove to the
chimney must be cleaned with a flue brush.
Periods of Prolonged Non-Use
If the stove is to be left unused for a prolonged period of time then it should be given a thorough clean to remove
ash and unburned fuel residues. To enable a good flow of air through the appliance to reduce condensation and
subsequent damage, leave the air controls fully open.
Extractor fan
There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emit smoke
and fumes into the room.
811142 BAV GB-7 March 2014

Aerosol sprays
Do not use an aerosol spray on or near the stove when it is alight.
Use of operating tools
Always use the operating tools provided when handling parts likely to be hot when the stove is in use.
Chimney Fires
If the chimney is thoroughly and regularly swept, chimney fires should not occur. However, if a chimney fire does oc-
cur turn off the stove immediately and isolate the mains electricity supply (if applicable), and tightly close the doors
of the stove. This should cause the chimney fire to go out. If the chimney fire does not go out when the above action
is taken then the fire brigade should be called immediately. Do not relight the stove until the chimney and flueway
have been cleaned and examined by a professional.
Permanent air vent
The stove requires a permanent and adequate air supply in order for it to operate safely and efficiently.
In accordance with current Building Regulations the installer may have fitted a permanent air supply vent into the
room in which the stove is installed to provide combustion air. This air vent should not under any circumstances be
shut off or sealed.
USER OPERATING INSTRUCTIONS
Please read the important notices given above before referring to the main instruction book for detailed operating
instructions.
Recommended fuels:
Please note that HETAS Ltd Appliance Approval only covers the use of wood logs on this appliance. HETAS Ltd Appro-
val does not cover the use of other fuels either alone or mixed with the recommended fuels listed above, nor does it
cover instructions for the use of other fuels. The stoves have a refuelling interval of 0.75h to achieve the nominal
rated output. Wood logs should be seasoned with a moisture content of around 20%.
811142 BAV GB-7 March 2014

Refuelling on to a low fire bed:
If there is insufficient burning material in the firebed to light a new fuel charge, excessive smoke emission can
occur. Refuelling must be carried out onto a sufficient quantity of glowing embers and ash that the new fuel charge
will ignite in a reasonable period. If there are too few embers in the fire bed, add suitable kindling to prevent exces-
sive smoke.
Fuel overloading:
The maximum amount of fuel specified in this manual should not be exceeded, overloading can cause excess smoke.
Operation with door left open:
Operation with the door open can cause excess smoke. The appliance must not be operated with the appliance door
left open except as directed in the instructions.
THE CLEAN AIR ACT 1993 AND SMOKE CONTROL AREAS
Under the Clean Air Act local authorities may declare the whole or part of the district of the authority to be a smoke
control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any fixed boiler if
located in a designated smoke control area. It is also an offence to acquire an ”unauthorised fuel” for use within a
smoke control area unless it is used in an ”exempt” appliance (”exempted” from the controls which generally apply in
the smoke control area).
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless
fuels or exempt appliances for use in smoke control areas in England. In Scotland and Wales this power rests with
Ministers in the devolved administrations for those countries. Separate legislation, the Clean Air (Northern Ireland)
Order 1981, applies in Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke
control areas have been ”authorised” in Regulations and that appliances used to burn solid fuel in those areas (other
than ”authorised” fuels) have been exempted by an Order made and signed by the Secretary of State or Minister in
the devolved administrations.
Further information on the requirements of the Clean Air Act can be found here : http://smokecontrol.defra.gov.uk/
Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision of
smoke control areas and you can contact them for details of Clean Air Act requirements
811142 BAV GB-7 March 2014

Appliance Exemption:
The Contura 500, 700, i4, i5, i30 and i40 series are recommended as exempt appliances under the Clean Air Act
1993 when burning dry seasoned wood logs in accordance with the instructions and when fitted with the permanent
stops detailed below:
The Contura 500 series must be fitted with a mechanical stop to prevent closure of the air control vent beyond the
20% open position when sold into smoke control areas.
The Contura 700 series must be fitted with a mechanical stop to prevent closure of the air control vent beyond the
28% open position when sold into smoke control areas.
The Contura i4 series must be fitted with a mechanical stop to prevent closure of the air control vent beyond the
30% open position when sold into smoke control areas.
The Contura i5 series must be fitted with a mechanical stop to prevent closure of the air control vent beyond the
30% open position when sold into smoke control areas.
The Contura i30 and i40 series must be fitted with a mechanical stop to prevent closure of the air control vent
beyond the 27% open position when sold into smoke control areas.

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 building owner 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.

Installation by authorised
technician
This manual contains instructions about
how the stoves must be assembled and
installed. To ensure the function and safety
of the stove, we recommend that the
installation is carried out by an authorised
technician. Contact one of our dealers who
can recommend suitable technicians.
Building application
These main insructions may give guidance
which would contravene national building
regulations. Please refer to supplementary
instructions or ask your local authority for
advice regarding building regulations.
Before installing a stove or erecting a
chimney it is necessary for you to make
a building application permission to your
local authority.
Structural support
Check that the wood joists are strong
enough to bear the weight of the stove and
chimney. The stove and chimney can usually
be placed on a normal wooden joist in a
single occupancy house if the total weight
does not exceed 400 kg.
Hearth plate
Due to the risk of falling embers, a
flammable floor must be protected by a
hearth plate. It must extend 300 mm in
front of the stove and 100 mm on each side
of the stove, or have a 200 mm extension
on each side of the opening. The hearth
plate can consist of natural stone, concrete,
metal plate or glass. A painted metal
or glass hearth plate is available as an
accessory for these models.

• The stove meets the requirements for connecting to chimneys
dimensioned for 350°C flue gas temperature.
• The external diameter of the connection sleeve is 150 mm.
• The stove 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. Minimum recommended chimney length is
3,5 m and a suitable cross section area is 150-200 cm² (140-160
mm in diameter).
• 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.
• Carefully check that the chimney is sealed and that there is no
leakage around soot hatches and flue connections.

54 SUPPLY AIR/ACCESSORY
Supply of combustion air
When a stove is installed in a room, the demand for air supply to
the room increases. Air can be provided indirectly via a vent in
the outer wall or via a duct from the outside that is connected to
the connector on the underneath of the stove. The amount of air
needed for combustion is approximately 25m3/h.
The connector has an external diameter of 67 mm. When duct
routing further than 1 m the pipe diameter must be increased to
100 mm and a correspondingly larger wall vent must be selected.
In hot areas the duct should be insulated with 30 mm mineral wool
covered with a moisture inhibitor (plastic). 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.
Through the external wall.
Indirect air supply through the external wall.
Through floor and foundation slab.
Through floor and wall-and-cavity foundation.
