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. Further information on the requirements of the
Clean Air Act can be found here: https://www.gov.uk/smoke-control-area-rules.
The Model T500.1 air heater has been recommended as suitable for use in smoke
control areas when burning softwood, hardwood, medium density fibreboard (MDF) or
chipboard off cuts. The fuel must not contain halogenated organic compounds or
heavy metals as a result of treatment with wood-preservatives or coatings.
Please note the following advice:
Refuelling on to a low fire bed
If there is insufficient burning material in the fire bed 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.
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.
