Introduction
May we take this opportunity to thank you for choosing one of our stoves. These
appliances are designed to burn wood logs and wood derived fuels. It is essential that your
wood has been seasoned to ensure that it is sufficiently dry for burning. You can determine
the moisture content of your logs by using a digital moisture meter, your logs need to be
below 20% moisture content before they are considered dry enough for burning.
Never burn wood that contains paint, glue or any other chemicals
See the section “Lighting the Stove” for further details. After reading this document, if there
is anything you are unsure about, please contact your dealer or our Technical Support
Department.
These instructions cover the basic principles to ensure the satisfactory installation of the
stove, although detail may need slight modification to suit particular local site conditions. In
all cases the installation must comply with current Building Regulations, Local Authority
By-laws and other specifications or regulations as they affect the installation of the stove.
It should be noted that the Building Regulations requirements may be met by adopting the
relevant recommendations given in British Standards BS 8303, BS 6461 and BS 7566 as
an alternative means to achieve an equivalent level of performance to that obtained
following the guidance given in Approved Document J.
Please note that it is a requirement under the Broseley Fires warranty system that
the installation of the stove is carried out by a Competent Person registered with a
Government approved Competent Persons Scheme. HETAS Ltd operate such a
Scheme and a listing of their Registered Competent Persons can be found on their

Hearth Requirements & Clearances
Your stove must be installed on a solid, level non combustible hearth. The hearth
does not need to be constructional but must be at least 12mm thick. The hearth protrusion
in front of the stove to carpets or wooden floors must be at least 300mm. As it is possible
for fuel to fall out on opening the door, a fender must be fitted if the hearth is flush with the
carpet.
These are just a few hearth specifications. Please refer to Building Regulations Approved
Document J (Hearths) for more specific details.
Clearances to combustibles are detailed in the diagram below. 300mm above and 100mm
to the side must be obtained to any flammable material such as wooden surrounds for
example. These figures are based on the fact that the stoves forward projection is no more
than 150mm.

MS11-11 Issue 3 7

Chimney Requirements
This appliance must not be fitted into a chimney serving another heating appliance. It is
most important that there is no obstruction in the flue or chimney. Please ensure that any
existing chimney is clear of obstruction and swept clean immediately before installation of
the new stove. If the chimney has been used for an open fire it is recommended that it be
swept for a second time having been used for a month following installation.
A flue draught minimum of 12 Pascals to a maximum 16 Pascals is required for
satisfactory appliance performance. A properly built masonry or factory constructed
chimney (with a minimum vertical height of 5 metres) should ensure a consistent draught
(draw).
The flue draught should be checked under fire at high output. If you have any doubts about
the suitability of your chimney, consult your local dealer/stockist or engineer. If your flue
draft is below the minimum recommendation then it may be necessary to increase the
vertical chimney height, add additional flue insulation or possibly add a special cowl to the
top of the chimney (e.g. anti down draft cowl to eliminate wind induced down draft).
The outlet from the chimney should be above the roof of the building in accordance with
the provisions of Building Regulations Approved Document J.
If installation is into an existing chimney then it must be sound and have no cracks or other
faults which might allow fumes into the house. Older properties, especially, may have
chimney faults or the cross section may be too large i.e. more than 230 mm x 230 mm.
Remedial action should be taken, if required, seeking expert advice, if necessary. If it is
found necessary to line the chimney then a flue liner suitable for solid fuel must be used in
accordance with Building Regulations Approved Document J.
If there is no existing chimney then either a prefabricated block chimney in accordance
with Building Regulations Approved Document J or a twin walled insulated stainless steel
flue to BS 4543 can be used. These chimneys must be fitted in accordance with the
manufacturer’s instructions and Building Regulations.
The stoves flue spigot is designed to accept a 6” / 150mm diameter pipe, it is possible to
connect the flexible liner to the spigot using self tapping screws. If no flexible liner is
present, the stove will need to be securely sealed into the fireplace opening (see section
“Assembly” for further information).
For sweeping purposes it is possible to sweep through the appliance, however you will
need to remove the internal baffle(s) to do so (see section “Assembly” for further
information).
MS11-11 Issue 3 8

Combustion Air Requirements
In order for the stove to perform efficiently and safely there should be an adequate air
supply into the room in which the stove is installed to provide combustion air. This is
particularly necessary in modern houses where drafts have been almost eliminated by
double glazing etc.
Under UK building regulations any appliance over 5kW MUST have a fixed
permanent air vent (see building regulations approved document J for further
information).
There must not be an extractor fan fitted in the same room as the stove as this can cause
the stove to emit fumes into the room. It is necessary to install a wall vent to provide the
necessary combustion air and to prevent the depletion of oxygen in the room.
MS11-11 Issue 3 9

Assembly
Smoke Exempt modification. Evolution 4
With both the Evolution 4 &
7 when it comes to
installations in smoke
control areas, you will need
to adjust the secondary air
intake to ensure
permanent combustion air.
You will need to remove
the six screws holding the
rear steel cover in place,
once you have removed
the cover you will be able
to see the mechanism
fixings as shown. The
fixings indicated will need
to be removed and re-fixed
one position to the right
(one at a time).

MS11-11 Issue 3 10

Assembly
Liner Connection
Unbolt the flue spigot from the stove (done by removing the internal baffle to access the
fixings). Connect and seal the 150mm diameter flexible flue liner into the flue spigot, this
can be done by screwing the liner using the 2 holes located in the spigot.
Extra care should be taken to ensure an air tight seal between the liner and the spigot.
(additional rope and or fire cement may be required).
Finally insert the stove into the fireplace and connect the flue spigot to the appliance by
means of the 2 bolts supplied. The spigot fixings are accessed from the inside of the stove.
IT IS RECOMMENDED THAT THIS STEP IS COMPLETED AFTER FIRST SITING THE
STOVE AND ENSURING SECURE POINTS ARE MARKED AND OR DRILLED.
Un-lined Chimney Connection
If the chimney is not being lined it is important that the stove is securely sealed into the
opening (a gas tight seal to BS 8303-1).A 12mm self adhesive rope is supplied to assist
with this, however additional sealant may be required to ensure a sound seal. The seal
needs to continue at hearth level as well as sides and top.
MS11-11 Issue 3 11

Assembly
With both the Evolution 4 & 7 insert stoves,
several fixing points are provided for ease of
installation. The fixing points will come sealed
using a bolt and nut, which simply need to be
removed from the appropriate fixings.
Screws/fixings are not provided with the
stove as these will need to suit the hearth
and surround material.

Controls Layout
The diagram below shows the position of the air controls, these controls need to be
operated correctly to control the combustion rate of the stove.
The top air control is classed as the “Secondary Air Intake” as it brings air in above the
grate. The lower air control is classed as the “Primary Air Intake” as it brings air in below
the grate.
See the following section for a more detailed description of how this control works.
MS11-11 Issue 3 15

Controls Explained
Fire needs air to burn therefore the stove is fitted with air controls that allow you to
regulate the amount of combustion air therefore controlling the burn rate within the
appliance.
Secondary Air Intake
The secondary air intake is located on the top of the stove, it is in the form of a slider.
Having the slider pushed to the right indicates that the air intake is in the closed/minimum
position and to the left indicates it is in the fully open/maximum position.
In smoke controlled areas you should fit the smoke exempt washer behind the control, this
will prevent the control from fully closing.
Air entering through this control is directed through the holes in the rear firebrick and also
down the inside of the glass creating the AIRWASH system – see below. The air wash
system allows the glass to remain soot and particle free. This control is used at initial
lighting and to control the burn rate of your wood.
The sections LIGHTING THE STOVE & BURNING WOOD give a step by step guide on
how to operate this control.
Primary Air Intake
The primary air intake is located below the door and is also in the form of a slider. Having
the slider pushed to the right indicates that the air intake is in the closed/minimum position
and to the left indicates it is in the fully open/maximum position.
The primary air intake is used at initial initial lighting to provide additional air to heat the
chimney/flue.
Air wash System
Air wash is a system where secondary air is drawn into the stove (by combustion) through
the secondary air control and is deflected down the back face of the glass, thus preventing
the smoke coming into contact with the glass. It does not mean that you will never have to
clean the glass, but substantially lengthens the periods between having to do so. The air-
wash system works best when burning dry wood. Wet wood will produce more deposits
on the glass. Also, deposits will form on the back of the glass when the stove is operated
on low heat for extended periods (where fuel is only just smouldering).
MS11-11 Issue 3 16

Recommended Fuels
The HETAS Ltd. appliance approval along with approval in a smoke controlled area only
covers the use of the following fuels in this appliance:
• Wood logs not exceeding 20cms in length and 8×8cm thick. The fuel must not
contain halogenated organic compounds or heavy metals as a result of treatment
with wood preservatives or coatings.
Approval does not cover the use of other fuels either alone or mixed with the suitable fuels
listed above, nor does it cover instructions for the use of other fuels.
Do NOT burn wet wood, This will give a poor heat output and will cause heavy deposits
of soot and tar to accumulate on the glass and throughout the stove and flue. The coating
of soot and tar in the chimney is volatile creating a high risk of chimney fires. A growing
tree contains a high percentage of water, the wood needs to be dried out (seasoned)
before it is suitable for burning (this can take several years). Wood logs are best stored in
a stack, sheltered from the weather, in a well ventilated area and raised off the ground.
This allows the air to circulate and prevents mildew.
Do NOT burn pallet wood or wood containing paint, glue or other chemicals. Burning this
type of wood will result in damage to the appliance, any such damage will not be covered
by the products warranty.
MS11-11 Issue 3 17

Lighting the Stove
Curing
On initial firing you will notice a very pungent odour, this is caused through the curing of
the paint, we recommend starting with short burning sessions (with smaller quantities of
fuel) and build up gradually to allow the components of the stove to settle. Opening doors
and windows will allow the paint curing odour to dissipate and to allow ventilation into the
room. Curing times can vary but typically should take around 8-12 hours (operation at high
output) to complete.
Kindling
Stage1
With the Primary and Secondary air intakes in the fully open position and the door open,
start your fire using twists/balls of newspaper. Form a bed on the grate using the
newspaper (or place several fire-lighters), then add a generous amount of dry kindling
onto the newspaper. Ensure their is sufficient air gaps between the kindling (a criss cross
or pyramid style pattern is ideal to accomplish this).
Kindling -----------
Newspaper -------
Stage 2
Ignite the paper underneath using a match or suitable fire-lighter. Allow the paper and
kindling to burn until it reduces down into hot embers. If the fire is dying during this stage
the door can be closed but not latched leaving a small gap for extra combustion air.
Stage 3
Add another generous load of dry kindling and allow to burn down.
It may be necessary to repeat stage 3 if the chimney is cold or if you find you have smoke
entering the room. This stage is vital for getting heat into the chimney which will create the
draw that takes the smoke away, we would expect this stage to take between 15-20
minutes.
It is critical that you do not leave the stove during the entire lighting and kindling
stage. See Burning wood section for the next steps in the sequence.
MS11-11 Issue 3 18

Burning Wood
Once you have kindled your stove (see previous page) and your chimney (flue) is
sufficiently heated and a large base of burning embers is present, you are ready to start
adding you logs.
Stage 4
Place 1-3 small logs onto the bed of hot embers using the gloves provided, close the door
but leave both air intakes in the fully open/maximum position. Allow the logs time to fully
ignite and turn black then close the primary air intake fully (leaving secondary fully open).
Stage 5
Once the smaller logs have burned down you can now add 2-3 larger (or full size) logs.
Leave the secondary air intake fully open until the new fuel turns completely black. You
can now close down the Secondary Air Intake as required. You will now need to control the
burn rate of the stove using the secondary air intake. You are looking for a controlled flame
(not smouldering in the embers or licking around the lid) this is mostly visual although a
flue pipe thermometer will help you determine the amount of air required and is
recommended for the initial lightings.
Stage 6
Refuel as and when required. Take care to open the door gradually as flames may lick out
and always use the gloves. Try to avoid closing the Secondary air control fully (as this will
cause the stove to fill up with smoke) If you no longer want to keep the fire going simply
allow it burn out.
Please note this is the standard lighting/ignition sequence, however there are some
changes to this when burning in a smoke control area. Please see “Smoke Exempt
Requirements” on the following pages.
MS11-11 Issue 3 19

Smoke Exempt Requirements
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).
The Secretary of State for Environment, Food and Rural Affairs has powers under theAct
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 eVolution Inset Wood burning stoves have been tested by GASTEC under the
PD6434 standard and have passed the emission requirements for exemption under the
Clean Air Act. Subsequently it has been exempt for use in smoke control areas when
burning wood only. Below are detailed operation techniques that must be adhered to
at all times when burning in a smoke control zone.
