1 Introduction

The appliance is designed to heat domestic residential and social spaces. The stove is intended for use only by
adults with occasional attendance and supervision. The room in which the stove is installed must be provided with
a sufficient fresh air supply, possibly by gaps through windows and doors. In well-sealed buildings, sufficient fresh
air supply to the room must be ensured by a vent of 550mm2 for each Kilowatt of rated nominal output.

The local Building Control department must be consulted prior to any DIY installation.

Please follow all of the instructions when installing and operating the stove.

The Clean Air Act 1993, Smoke Control Areas and DEFRA

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 regulations 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 Arctic 5, Lumo 5, Lumo 5 rotary, and Orbit 5kW stoves are exempt appliances that have been recommended as
suitable for use in smoke control areas when burning wood logs; and have been factory fitted with a secondary air
control which cannot be fully closed.

2 COMBUSTION AND HEATING FUNCTION

The stove is designed for combustion of wood and wood ‘eco’ briquettes by a burn-through system that ensures
excellent combustion conditions. If not in a smoke control area, lignite briquettes may also be used.

The heating function is achieved mainly by convection, and partially by radiant heat. The convection system is able
to heat up particularly cold rooms relatively quickly.

Convection heating works by sucking in the air from the room through the vents at the bottom of the stove into
the space between the firebox and the outer casing. It is heated in-between the double walls of the stove causing
it to rise. It flows back into the room through the vents in the upper part of the stove.
Heat is also radiated by the surface of the stove body, but the main source of radiant heat is the glass door surface.

3 DESIGN

The appliance is fabricated from pressed and welded sheet steel, and may include as an optional extra a stone or
ceramic outer casing. The stove combustion chamber is lined with refractory (heat resistant) vermiculite firebricks.
The refuelling door of the stove has a ceramic window, resistant to very high temperatures and thermal shocks.
The ceramic is almost clear, allowing heat radiation from the combustion chamber (‘firebox’) to pass through; and
allows a view of the flames when burning. There is a sold cast iron grate at the bottom of the firebox and an ash pit
below. The stove is spray painted with silicone polymer paint, resistant to high temperatures.

Primary air, secondary air and tertiary air is supplied to the firebox. Primary air is used for lighting and is
channelled under the grate; secondary air is channelled onto the glass from above and provides the self-cleaning
(‘air-wash’) of the glass. Tertiary air is fed to the upper part of the firebox through the vents at the back of the
firebox, and provides further combustion of un-burnt gases (burnout).

The Arctic, Lumo (non-rotary) and Orbit stoves have the option of feeding combustion air through the Central Air
Feed (CAF) from the outdoors. If the CAF is used, the stove does not take air from the room. These options are
specified in the Product Technical Sheet (TS).

4 SAFETY REQUIREMENTS

4.1 General provisions

 The principles of fire protection in the Building Regulations publication “Approved Document J -

Combustion appliances and Fuel Storage systems (2010 edition incorporating 2010 and 2013 amendments)

http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADJ_2010.pdf must be observed when operating and

installing the stove.

 The appliance may be used in a normally experienced environment according to Approved Document J .

In any change of environment, when a temporary danger of fire or explosion could emerge (e.g. when using glues,
solvents, paints etc.), the stove must not under any circumstances be in operation. The stove may be used further
only after thorough ventilation of the room, at best by draught.

 The stove must be connected to a chimney with a draught of at least 12 Pascals. The installer should

test and certify the adequacy of the draught. The stove may be connected only to its own independent chimney.

4.2 Safe distance of the appliance from combustible surfaces:

Hearth:

The appliances do not cause the hearth temperature to exceed 100°C and can be placed on a non-combustible,
non-constructional hearth of 12mm thickness. The hearth must exceed the dimensions of the stove by at least 15
cm on each side, 10 cm at the back and 30 cm to the front. It must have a minimum thickness of 12mm.
