You must purchase a smoke control version of the Mendip stove which is modified slightly to comply with regula�ons. Any
change to this modifica�on will invalidate the stoves compliance for smoke control areas.
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. 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. Similarly, In
Northern Ireland appliances are exempted by publica�on on a list by the Department of Agriculture, Environment and Rural
Affairs under Sec�on 16 of the Environmental Be�er regula�on Act (Northern Ireland) 2016. In Wales appliances are
exempted by regula�ons made by Welsh Ministers.

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 Christon 550 & 750 SE stoves have been recommended as suitable for use in smoke control areas when burning wood
logs. The appliances have been fi�ed with a modifica�on to fix the air controls at 0% open for 550 & 50% open for the 750
model in its minimum posi�on.
Only specific SE cleanheat models are suitable for smoke control areas (page 5), altera�ons should not be a�empted.
Mendip smoke control stoves should not be burnt with the door le� open.
T
he 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.
RE-FUELLING WHEN BURNING WOOD
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 UAC fully and slide to the le� posi�on. Unlatch the door to equalise pressure with the room. Open door
gently, add one piece of wood (4.8kW model) add two pieces of wood (8.7kW models) (please check weight tableb elow) and
close the door. Once the flames from the logs are fully established slide UAC control to right posi�on and push air control as
desired. The stove is only suitable for intermi�ent use only: do not run overnight or for long periods una�ended.
Experience will determine the settings that produce best results (efficient opera�ng temperature range is between 200c and
400c).
