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.
The WESTFIRE Uniq 44/ 45/ 46 SE stoves have been recommended as suitable for use in smoke control areas
when burning wood logs. The appliances have been fitted with a modification to fix the air controls at 56% open
for WESTFIRE Uniq 44/ 45/ 46 model in its minimum position.
Only specific SE models are suitable for smoke control areas, alterations should not be attempted.
Westfire smoke control stoves should not be burnt with the door left 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. After this period, with flames from the logs fully established, close the secondary air supply
to the low output setting. When operating at high output (secondary air set fully open) the new refuel charge
does not require any boost air to establish combustion.
RE-FUELLING WHEN BURNING WOOD
BURNING WOOD IN A SMOKE CONTROL AREA
To re-fuel your stove in the cleanest way only refuel your stove when flames have died down and you have
glowing embers. Before refuelling, open air controls fully and slide. Unlatch door to equalise pressure with the
room. Open door gently, add one piece of wood and close the door. Once the flames from the logs are fully
established move air control to nominal position. The stove
is only suitable for intermittent use only: do not run overnight or for long periods unattended.
Experience will determine the settings that produce best results. Use a flue thermostat to check the stove is not
overheating. Flue thermostats should be placed directly above collar of the stove on a non insulated section of
pipe. (efficient operating temperature range is between 200c and 400c)

SE MODELS – smoke exemption modification
Smoke exempt models are factory fitted with a air stop on the air control slider:
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.
