The Clean Air Act 1993 and Smoke Control Areas
Under the Clean Air Act local authori�es 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 publica�on on a list by the Secretary of State in accordance with
changes made to sec�ons 20 and 21 of the Clean Air Act 1993 by sec�on 15 of the Deregula�on Act 2015.
Similarly in Scotland appliances are exempted by publica�on on a list by Sco�sh Ministers under sec�on 50 of
the Regulatory Reform (Scotland) Act 2014.
In Wales and Northern Ireland these are authorised by regula�ons made by Welsh Ministers and by the
Department of the Environment respec�vely.

Your local authority is responsible for implemen�ng the Clean Air Act 1993 including designa�on and
supervision of smoke control areas and you can contact them for details of Clean Air Act requirements.
The Churchill 5 Mk.4 SE Dual Control mul�fuel stoves have been recommended as suitable for use in smoke
control areas when burning wood logs. The appliances can also burn authorised fuels in smoke control areas.
More informa�on regarding authorised fuels can be found at
h�p://smokecontrol.defra.gov.uk/fuels.php
.
The SE appliances need no modifica�on to the air control,
altera�ons should not be a�empted.
Mendip Stoves
smoke control stoves should not be burnt with the door le� open.
The refuelling procedure :
Allow the newly charged fuel to burn with the secondary air control set at maximum for up 3 to 4 minutes. A�er
this period, with flames from the logs fully established, close the secondary air supply to the low output se�ng.
When opera�ng at high output (secondary air set fully open) the new refuel charge does not require any boost
air to establish combus�on.
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 quan�ty 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 & doors le� open
Opera�on with the air controls fully open can cause excess smoke. The appliance must not be operated with
air controls, appliance dampeners or the door le� open except as direct in the instruc�ons.
