validating your warranty.
We would like to thank you again for trusting KLOVER products, and we also inform you that these
models are the result of forty years experience in the manufacture of solid fuel products using water as
heat transfer fluid.
Each and every single part of our central heating cookers is manufactured by qualified staff using the most
modern work equipment.
The manual contains a detailed description of the central heating cooker and its operation along with
instructions for proper installation, basic maintenance and checks to be run regularly. It also contains
practical advice to achieve maximum efficiency with minimum fuel consumption.
The cooker heat output canvary depending on the type of pellet used.
Enjoy heat with KLOVER!
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).
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless fuels
or exempt appliances for use in smoke control areas in England. In Scotland and Wales this power rests with Ministers in
the devolved administrations for those countries. Separate legislation, the Clean Air (Northern Ireland) Order 1981,
applies in Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas have
been "authorised" in Regulations and that appliances used to burn solid fuel in those areas (other than "authorised"
fuels) have been exempted by an Order made and signed by the Secretary of State or Minister in the devolved
administrations.
Further information on the requirements of the Clean Air Act can be found here :
http://smokecontrol.defra.gov.uk/
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 Klover SMART 120 (models - SM120, SM120-BP, SM120-P, SM120-B) have been recommended as suitable
for use in smoke control areas when burning wood pellets.”
