UK Smoke control areas

The Contura 50 series has been recommended as suitable for use in smoke control areas when burning wood logs and operated in accordance with these 
instructions and when fitted with a permanent stop to prevent closure of the air control vent beyond the 30% open position when sold into smoke control 
areas.  The instructions for modifying the air control with the permanent stop (damper blocker) are provided at page 40.

USER OPERATING INSTRUCTIONS

Please read these important notices before referring to the main 
instruction for detailed operating instructions.

Stove performance

Refer to the main instruction manual for details of the stove’s
performance.

Recommended 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 
30%. 

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 excessive smoke.

Fuel overloading:

The maximum amount of fuel specified in this manual should not be 
exceeded, overloading can cause excess smoke.

Air Controls:

To avoid the risk of excess smoke emission the air controls should always be 
used as directed in the instructions. 
 

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.

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.

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).
In England appliances are exempted by publication on a list by the 
Secretary of State in accordance with changes made to sections 20 and 21 
of the Clean Air Act 1993 by section 15 of the Deregulation Act 2015.
In Scotland appliances are exempted by publication on a list by Scottish 

Ministers under section 50 of the Regulatory Reform (Scotland) Act 2014. 
Similarly, in Northern Ireland appliances are exempted by publication on a 
list by the Department of Agriculture, Environment and Rural Affairs under 
Section 16 of the Environmental Better Regulation Act (Northern Ireland) 
2016.  In Wales appliances are exempted by regulations made by Welsh 
Ministers.

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.
