Introduction
May we take this opportunity to thank you for choosing one of our cast iron, multifuel
stoves.
The term multifuel refers to the fact that the appliance is capable of burning either wood
logs or coal (that is suitable for closed appliances). Both of these fuels have very different
air requirements in order for them to burn correctly, therefore the air controls need to be
operated differently depending on the fuel being burned (see section “Stove Operation”).
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
Byelaws 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 and BS EN 15287-1 2007 +
A1 2010 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
website at www.hetas.co.uk.

Hearth Requirements & Clearances
These appliances WILL require a full constructional hearth as laid out in building
regulations approved document J.
Your stove must be installed on a solid, level non-combustible hearth. The hearth
protrusion in front of the stove to carpets or wooden floors must be at least 300mm. As it is
possible, that on opening the door of the stove for fuel to fall out, 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
The stove requires the following clearances around it to ensure the heat is released into
the room and to allow sufficient combustion air flow. A combustible material clearance is
given to prevent damage to any items that may be affected by heat.

NOV12GB Issue 2 8
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 10 Pascals to a maximum 14 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). 45° bends can be used in the flue run (maximum of four bends) you will need to
add an extra 1 metre of vertical flue height for each bend.
The flue draught should be checked under fire at high output and if it exceeds the
recommended maximum, a draught stabiliser must be fitted so that the rate of burning can
be controlled, and to prevent over firing (See section “Warning Notes”). 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 neccesary 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.
If a flexible liner is required the liner diameter must not be less than 6”.
Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends are not
permitted. . For top flue installations it is possible to sweep through the appliance by
removing the internal baffle however it is recommended that you provide adequate access
(e.g. easily accessible soot door).

NOV12GB Issue 2 9
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. The requirement calls for 550mm2 of free ventilation per kW
above the 5kW threshold, which means that this appliance will require a fixed
permenant air vent that provides 25 x 550mm2of combustion air.
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.
(see building regulations approved document J for further information).

Assembly
The diagram below shows the main components of the stove and how it can be broken
down for transport purposes.
s from 6 down to
1.

NOV12GB Issue 2 11
Assembly
It is important that the grates are installed the correct way up, the slots in the grate are “V”
shaped and should be situated so the narrowest part of the channel faces up (this will
allow ash to fall into the pans below)

NOV12GB Issue 2 12
Plumbing Advice
Boiler installations should only be carried out by qualified heating engineers who
hold a HETAS wet systems certificate or equivalent. A site survey prior to
commencing installation is highly recommended to identify any potential problem
areas.
The stove is fitted with four 1” female pipe connections as shown below. It is important to
note that the boiler on this appliance is one singular open vessel so it is perfectly possible
to only use two connections (and cap the others off).
The top connections are the flow and bottom connections return. It is good practice to use
diagonal opposites to promote good flow around the boiler e.g. top left flow and bottom
right return.
Please note this appliance is not suitable for “DIY” installation therefore only
general guidance is given in this section as your installer will already be familiar
with open vented boiler installation (including best plumbing practices and building
regulations).

NOV12GB Issue 2 13
Plumbing Advice
Open Vented Plumbing
It is critical that this appliance is only connected to open vented systems, which must
include a gravity circuit with an expansion tank open to the atmosphere.
When installing this appliance on a gravity circuit, the system should consist of a
tank/indirect cylinder fixed in an upright position and should be connected to the boiler by
28mm pipe (both flow and return). The pipes should not exceed 7.8m in length. The
shorter the run of pipe work the more effective the appliance is going to be at heating the
water. The cylinder and pipe work should be lagged to minimise the heat loss in the
system.
A ‘heat-leak’ radiator must be incorporated into the system to dissipate any excess heat
produced from the boiler when connected demands are low. The heat leak radiator must
be sized at a minimum of 10% the boiler output. Fit the heat leak radiator in the gravity
circuit using 22mm pipe reducing to 15mm for no more than 300mm before the radiator.
Commission/Handover
Ensure loose parts are fitted in accordance with the instructions for “Assembly” given
previously. On completion of the installation, allow a suitable period of time for any fire
cement and mortar to dry out; a small fire may then be lit and checked to ensure the
smoke and fumes are taken from the stove up the chimney and emitted safely outdoors.
Do not run at full output for at least 24 hours.
On completion of the installation and commissioning, ensure that this installation and
operation manual for the stove is left with the customer. Ensure the customer is advised on
the correct use of the appliance with the fuels likely to be used on the stove and warn them
to use only the recommended fuels for the stove.
Advise the user what they should do if smoke or fumes be emitted from the stove. The
customer should be warned to use a fireguard to BS 6539 in the presence of children,
aged and/or infirm persons. Advise the user not to fit an extractor fan in the same room as
the stove as this can cause the stove to emit fumes into the room.

Controls Layout
The stove is fitted with a number of controls which need to be correctly operated in order
to light and maintain a fire.
Thermostat

NOV12GB Issue 2 18
Controls Explained
Primary Air Intakes (manual operation)
The primary air intakes are located at the bottom of each door, they are in the form of
sliders. These sliders form the manual primary air intake system, when operating the this
air intake manually it is critical that the thermostat control is turned fully anti-
clockwise (closed). Having the slider pushed to the left indicates the intake is fully open
(and to the right is fully closed). This particular air intake is adjustable throughout the area
left to right to control the total amount of air entering below the grate for combustion.
The primary air intake is used on initial firing of the stove or when burning coal etc. Please
see the BURNING COAL for a more in depth description.
Secondary Air Intake
The secondary air intake is the slider located above the doors, as with the primary intake
left is fully open and right fully closed. Air entering through this control is pushed down the
inside of the glass creating the Airwash System – see below. This particular design also
allows the air to be released on top of the grate which is ideal when burning wood
products. Please see section BURNING WOOD.
Tertiary Air Intake
The tertiary air intake is a flap located on the right hand side of the stove, This control
allows air to enter at a higher point inside the burn chamber and will provide an extra boost
of heat. This control can be used at initial start-up and when an additional boost of heat is
required.
Thermostat Control (Automatic operation)
This control is located on the front of the stove below the ash lip and is in the form of a
dial. The thermostat provides an automatically regulated primary air intake, when using
the thermostat it is critical that you keep the primary air intake sliders fully closed.
The thermostat regulates the flow of primary air which enters the appliance through a flap
on the rear, the flap will close (cutting off the air supply) when the water temperature inside
the boiler reaches 80°c. Turning the dial fully clockwise indicates the control is compleyley
open (maximum combustion air) and fully anti-clockwise indicates the control is closed
(zero combustion air). This particular air intake is adjustable throughout the rotation of the
dial.
Airwash System
Airwash is a system where secondary air is drawn down the inside of the glass by
combustion. The flow of air helps prevent 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 cleaning. The air-wash system works best when burning dry wood as
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).

NOV12GB Issue 2 19
Recommended Fuels
This appliance has obtained CE EN13240 approval for burning –
* HETAS approved coal suitable for a closed appliance.
* Split Wood logs not exceeding 35cms in length and not over 20% moisture content.
Approval does not cover the use of other fuels either alone or mixed with the suitable fuels
listed above.
Although approval covers the use of the smokeless fuels listed, the claimed rated output,
has been obtained burning a single representative smokeless fuel, under standard test
conditions. However, in the home, a variety of operating conditions can occur and the
performance of the appliance may vary to some degree with these conditions and different
fuels may need to be burnt at different rates to provide the same heat output.
The recommended fuels are Wood logs no longer than 35cms (dry, seasoned to under
20% moisture) and solid mineral fuels (e.g. Natural smokeless fuels) Larger coal briquettes
are recommended as they concentrate less heat in one spot reducing the likelihood of
damage to the grate. Ask your local fuel merchant or consult the HETAS website for more
details on these fuels.
Only authorised smokeless fuels may be used in smoke control areas.
Do NOT burn “Housecoal” or any other coal which are intended for use on open
fires. Suitable coal needs to be designed for use on closed appliances. Open fires send a
large amount of heat up the chimney therefore the fuel needs to burn extremely hot in
order to send heat into the room, closed appliances are highly efficient and send little heat
up the chimney therefore the fuel does not need to burn as hot. Using open fire coal on a
closed appliance will cause excessive wear on the stove and could result in damage which
will not be covered by the products warranty.
Under NO circumstances burn “petroleum coke” or any other chemically enhanced
fuel as it will burn out the internal grate and baffle plates in a very short period of time and
may damage the stove beyond repair.
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. Tar and soot
build-ups will also insulate the boiler causing poor heat transfer to the water, 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.

NOV12GB Issue 2 20
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
Ensure the secondary air slider is fully open and either the primary air sliders (manual
operation) or thermostat (automatic operation) are fully open (close the control according
to your operation preference) and the tertiary air intake flap is closed. With both doors
open, start your fire using twists of newspaper (or scrunched up balls) to form a bed on the
grates. Place 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 this stage 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 and Burning Coal sections for the next steps.
