2. HEATABLE AREA (VOLUME)

The heating capacity of rooms according to DIN 18893 for buildings in which the insulation is below the levels

recommended in the regulation is:

THERMO SOVRANA

SOVRANA

(120 BTU/m3) Well insulated: 387 m3 (120 BTU/m3) Well insulated: 186 m3

(160 BTU/m3) Average insulation: 290 m3 (160 BTU/m3) Average insulation: 107 m3

(200 BTU/m3) Poor insulation: 232 m3 (200 BTU/m3) Poor insulation: 73 m3

With adequate insulation, these values will be higher. With temporary use, the capacity is reduced by around 25%.

3. KEY ENVIRONMENTAL CONSIDERATIONS

To minimize the impact on the environment the following issues need to be considered when proposing to install a

solid fuel appliance:

•Local authorities (Councils) must be consulted for any restrictions that may apply to the use of solid fuel

appliances in certain areas such as smoke free zones.

•The appliance must be correctly sized to suit the space and necessary clearances must be strictly adhered

to.

•The appliance and flue system must be correctly installed to the current regulations in force at the time.

•The appliance must be correctly operated.

•The appliance and flue system must be properly maintained.

•It is also important to ensure that the dwelling to be heated is well insulated and is as energy efficient as is

practical before a heating appliance is chosen and installed.

•The correct fuel must be used.

5 THE ‘AIR’ CONTROLS

The stove is fitted with various air controls that adjust the flow of combustion air into the unit. It is very important that

these controls are fully understood in order to achieve the best results from the appliance.

When operating the controls, ensure that they are used in small increments and not changed by large amounts

suddenly. Do not use them like an on – off switch.

It is important that the controls are used correctly, in relation to the fuel being burnt, i.e. wood or coal.

The air controls are as follows:

•PRIMARY AIR CONTROL (FIG 1)

•SECONDARY AIR CONTROL (AIR WASH) (FIG 2)

•OVEN / HOTPLATE CONTROL (FIG. 3)

Front of

appliance

between

fire box

and

warming

drawer

5 A THE PRIMARY AIR CONTROL see FIG.1

The primary air regulator is found on the front of the main fire door and is in the form of a lever. This control will

primarily be used when burning coal. Coal needs the combustible air to enter from the below the grate on which the

coal is laid. Please read the chapter on burning coal to fully understand the method of control.

5 B SECONDARY AIR CONTROL see FIG. 2

The secondary air regulator is found on the front of the main fire door and is in the form of a lever. This control will

primarily be used when burning wood. Combustion air entering the stove through this vent will be directed down the

inside of the glass panel, this is known as the ‘air wash system’. It helps to keep sooty deposits from sticking to the

glass and obscuring the view of the flames. Having clean glass also improves the heat radiation through it.

FIG.1 PRIMARY AIR

FIG. 2 SECONDARY AIR

5 C OVEN / HOTPLATE BYPASS CONTROL see FIG 3

This control is positioned on the front of the appliance as shown in the FIG. 3. It has two settings. The hot gasses

generated by the burning fuel can be diverted using this control, to give greater heating to the hob or to the boiler.

You must only use this control when you have a clean burning, established fire. Look at the smoke coming out of

your chimney if you are unsure whether your appliance is burning cleanly. There is a small plate that has two

symbols on it representing a frying pan and a casserole dish. The frying pan symbolises the hob and the casserole

dish, the oven.

•HOB COOKING ONLY:

When the bar is pushed in towards the back of the cooker, the combustion gases flow over the top of the oven

and directly into the flue and up the chimney, heating the hob only. This is the position the lever needs to be in

when first lighting the appliance.

•OVEN COOKING:

When the control bar is pulled out, the hot combustion gases flow around the oven, heating it, then they exit the

stove. This control must only be operated when the fire is established and burning clean and HOT.

6 ADVICE ON DIVERTING THE HOT FLUE GASSES.

The oven and boiler heats up by having the hot gasses, that are given off the by the burning fuel, being diverted

around the channel within the appliance. The operator must only send clean gasses around this channel. This is

achieved by burning the correct fuel efficiently and not diverting the gasses too soon. A slow burning fire will

produce black smoke, so will burning wet, green, unseasoned wood with a moisture content of more than 20%.

Sending this black smoke around the channel will tar it up and the result will be a poor transfer of heat to the boiler,

the hob and oven. It is therefore critical that you establish a strong burning fire before diverting the gasses.

7 THE LIFTING GRATE

(THIS IS ONLY FITTED TO THE THERMO SOVRANA BOILER VERSION) The non boiler Sovrana has a fixed flat grate.

The Thermo Sovrana has a grate that can be raised and lowered by means of a scissor style jack. A crank handle is

provided and it attaches to the square peg located just above the ash drawer (see Fig 4).

This is useful if you wish to use the appliance in the summer and don’t want to send so much heat to the boiler.

Cranking the grate towards the hob means that less of the boiler is exposed to the hot gasses coming off the fuel. If

you are cooking on the hob only, and have no need to keep the fire going when you have finished, you can lift the

grate closer to the hob, thus allowing you to get the best heat from the fire as it slowly dies.

Ensure that the fire chamber and the crank mechanism are kept clean and well maintained.

FIG. 4 The lifting grate

FIG. 3 OVEN / HOTPLATE BYPASS CONTROL

8 FUEL OPTIONS

These appliances have been developed to burn wood as the primary fuel. The results quoted in our literature are

from test firings using beech logs with a moisture content of less than 20%. These appliances can burn brown coal

(Lignite) and briquettes made from Lignite. Coal should never be burnt in these appliances for long periods at a high

output. High calorific value coals such as anthracite should never be used; ever. The grates and internal

components of these appliances have not been developed for burning coal at high outputs. Do not burn wood and

coal at the same time as the efficiency of the appliance will be affected. It is OK to initially start the fire with coal and

then when there is a nice bed of embers in the fire chamber, put a load of logs in. You will need to use good quality

fuel in order to get the best results from your stove. Seek advice from your local fuel merchant as he will be able to

advise you on what fuel to use. Only use fuel that is suitable for a ‘closed appliance’.

Follow our guidance on fuel options also. Never burn ‘enhanced’ fuels such as ‘Petrocoke’.

Damage caused by overheating is not covered by the guarantee.

You should therefore always use the appliance with the door closed to avoid this, control the combustion rate of the

appliance by correct use of the air controls and ensure that the flue draught is not excessive.

8A BURNING WOOD

Hardwoods have a far greater calorific value than softwoods. Most firewood you purchase will be green and have a

fair amount of water content. It will need to be stored in a well ventilated shelter to season it.

Wood used in this appliance must have a moisture content of less than 20%. Damp or wet wood will quickly form tar

deposits on all the internal areas where the combustible gasses travel, preventing the efficient release of heat from

the appliance.

The inside of the chimney/flue will also be coated, there is a greater risk of a chimney fire occurring.

Always use good quality wood, store it under cover in a well ventilated area.

Avoid burning oak bark, as this forms tar at a very fast rate.

When selecting wood, also take into consideration ease of splitting, ease of ignition and burning, how much smoke

it produces and its "coaling" qualities. "Coaling" refers to the ability of a species of wood to form a long- lasting bed

of hot coals when burned. Coaling qualities improve with wood of a higher density. Wood is not a long burning fuel

and so it is not possible to keep the stove in overnight.

SEE BELOW (maintaining a coal / wood fire)

8B BURNING COAL

It is possible to burn coal on this stove even though it has been primarily designed to burn wood. Coals with high

calorific values must be avoided as they will destroy the internal components of the appliance. Do not burn

anthracite in this appliance.

Try different sorts of coals and contact your local fuel merchant to see which one gives you the best results. You are

looking to find the one that gives you the best heat output, be controllable, be able to stay in over night, not give

excessive ash or create too much clinker and not be too smelly. Any coal that has additives such as ‘petrocoke’

should not be used. These special fuels are for industrial boilers and will destroy the internal components of your

stove and invalidate your guarantee. The other coal worth avoiding is often described as ‘household coal’ which is

usually the cheapest and is intended for open fires.

Only use coal that is suitable for use in closed appliances. Never let the ash pan get too full.

A deep bed of coal is critical for the proper function of the appliance. Coal can be regulated better than wood; a

deep bed of coal does not mean that you can only run the stove hot. You can regulate the appliance using the air

controls. SEE BELOW (maintaining a coal / wood fire)

9 INITIAL BURNING AND CURING OF THE APPLIANCE

The first time that the appliance is lit, there will be an odour given off. This is the components of the appliance

curing. It will be necessary to ventilate the room in which the appliance is sited.

The first firing needs to be done carefully to allow all of the components of the appliance to settle gradually. Never

try to run the appliance flat out the first time you light it. It will be necessary to keep the fire burning for longer

periods rather than short periods the first four to five times. This will be the best way to achieve correct settling of

the appliance. Do not burn the appliance at an accelerated rate; a steady burn is all that is required.

Gradually build up the output of the fire so that no sudden stresses are put on the components of the appliance.

10 USING YOUR STOVE - IMPORTANT NOTES:

This appliance must be installed and commissioned by a fully qualified, registered engineer. HETAS engineers are

recommended by Broseley Fires. For your nearest search www.hetas.co.uk

THE SURFACES OF THIS APPLIANCE GET HOT WHEN THE APPLIANCE IS LIT. PLEASE ENSURE THAT CHILDREN, THE

ELDERLY, INFIRM AND PERSONS OF LIMITED INTELLIGENCE ARE MADE AWARE OF THIS.

Continued on next page………………….

USING YOUR STOVE - IMPORTANT NOTES:

Continued……….

•When lit, all surfaces of the appliance will get hot.

•Serious damage may result if the appliance is left running with the air controls fully open for extended periods.

•Make sure that none of the doors are left open while the appliance is in operation.

•Never leave the appliance unattended during the initial lighting sequence.

•Do not attempt to open the door immediately after igniting the fire. This could cause a flame flash out.

•Always wear the protective gloves when operating the appliance.

•Never burn enhanced fuels such as ‘Petrocoke’

•Do not overload the appliance with fuel.

•Never use chemicals or fluids such as gasoline, charcoal lighter, drain oil or kerosene to light a fire.

•Using the appliance on a very low output will cause excessive amounts of tar to build up inside the flue and can

be a serious fire risk, as this will fuel a chimney fire. You will need to have the flue cleaned and serviced more

regularly.

•Never overload the stove (consult the technical table - maximum allowable quantities)

•We advise that you have the appliance serviced annually by a competent heating engineer before the beginning

of a new heating season.

•Do not cover the permanent air vent that your heating engineer has installed; this is necessary for the correct

combustion of the appliance and your safety.

•Do not light the fire if there is a risk that any part of the system is frozen.

•Never block the permanent air vent that your HETAS engineer installed in the same room as the appliance.

11 LIGHTING AND MAINTAINING A COAL FIRE

All chimneys and flues act differently. After a while, you will find out how your unit works best for starting and

maintaining a coal fire. The correct flue draught is critical for the efficient operation of this style of appliance. Contact

your local fuel merchant to get good advice on the various fuels that are available locally to you. Low heat output,

large ash accumulation, difficulty of overnight burning and excessive tar deposits are just some of the signs of a

poor coal.

•Coal should only be used with chimneys that provide a strong and constant draft.

•Use scrunched up paper and dry kindling or fire lighters to start the fire.

•Open the primary and secondary air controls to the fully open position. The flue bypass control MUST be

pulled out to the open position and left in this position until there is a strong established fire in the firebox.

•Keep all the draft controls fully open till a bed of hot, glowing embers is established.

•When you have a good bed of glowing red wood embers, rake the glowing embers evenly over the grate

before adding a small amount of coal, still keep all the draft controls open at this stage.

•Continue adding small amounts of coal until you have about a 25 to 50mm bed of burning coal. We suggest

that you do not fully load the appliance until you have become completely familiar with the operation of ALL

the air controls.

•Don't add too much coal at one time as this will smother the fire. Allow sufficient time between each loading

for the coal in the stove to thoroughly ignite.

•Do not overload the appliance.

•Once the coal is burning with a blue flame, then the air controls can be adjusted.

•For best results, in an ideal situation, use the primary air control and close the secondary air control. The

output of the appliance can now be controlled using the primary air control. This is when burning COAL.

•Shake the ash into the grate. Use a poker. This is critical for the correct operation of the appliance. Always

release the ash before re-fuelling and whenever the fire is stifled by excessive ash on the grate.

•IMPORTANT: The calorific (heat) output of your appliance is affected by the operation of your chimney. If it

has a very strong draw, then you will need to adjust the air controls to allow less combustion air through the

appliance. A slow draw on a chimney will not give ideal results and will require a more exact adjustment of

the controls for correct combustion. If the flue draft is greater than the figure recommended by the

manufacturer, it will be necessary to fit a flue draft stabilizer.

12 LIGHTING AND MAINTAINING A LOG FIRE

All chimneys and flues act differently. After a while, you will find out how your unit works best for starting. Ensure

that the draught measurement is correct at the time of installation.

•Use scrunched up paper and dry kindling or fire lighters to start the fire. Lay these on the grate.

•Open the primary and secondary air controls to the fully open position. The flue bypass control MUST be

pulled out to the open position and left in this position until there is a strong established fire in the firebox.

•When the fire is burning hot, add small pieces of very dry wood, preferably hardwood as these generate

better embers.

•Keep all the draft controls fully open till a bed of hot, glowing embers is established.

•Once you have some red hot burning embers, open the door and rake the embers evenly over the grate

before adding larger pieces of wood.

•We suggest that you do not fully load the appliance until you have become completely familiar with the

operation of ALL the controls.

•For best results, in an ideal situation, open the secondary air control and close the primary air control. The

output of the appliance can now be controlled using the secondary air control. This is when burning LOGS.

The secondary air control will help keep the glass clean as it incorporates ‘air wash’ technology.

•Do not open the loading door too quickly when reloading the appliance as this can cause flames to flash out

the door.

•Do not overload the appliance.

•Do not burn painted or varnished woods, MDF, oak bark or any wood with more than 20% humidity.

13 ASH REMOVAL – CLEANING OUT THE ASH

The removal of the ashes should be done when the appliance is cold. Whether you burn logs or coal, you will be left

with ashes. They must be removed periodically for the correct and efficient operation of your appliance.

Don’t wait till the ash pan's completely full. The frequency of this ash removal will depend on the type of fuel being

burned, ie. Softwood, hardwood, coal or brickets; all create differing amounts of ash.

Keep in mind that cleaning your appliance boosts its efficiency, as ash, soot or tar deposits will block the heat from

coming out of the appliance, the boiler and oven will become insulated by the deposits.

Excess ash in the pan will cause a coal fire to go out and may cause severe damage to the grate. It may also

prevent the ash door from being shut correctly. Periodical inspection of the ash chamber is recommended.

Take care when removing the ash, as small bits of hot embers can stay dormant for long periods when buried in

ashes. These will then flare up again when exposed to oxygen, some knowledge of proper ash removal is required

for safety. Here are the important points:

Remove ashes to a metal container using a small trowel. Never vacuum the ashes unless it is a genuine ‘Ash Vac’.

This is a vacuum that is specifically designed for ash removal.

Place the filled ash bucket on a non-combustible surface, fit a lid for extra safety. When cold enough, dispose.

For your own protection, a pair of heat proof gloves and a dust mask may be necessary.

14 ASH DISPOSAL

The best thing to do with your ashes is to put them in your garden. Wood ashes are high in potassium, calcium,

sodium, magnesium, and phosphorus. Wood ash will make your soil more alkaline.

If you have no garden, you can dispose of completely cold ash with your household trash.

Place it in a tightly closed bag to keep it contained. Dispose of coal ash in your trash also, as it is not beneficial to

your garden. As with all ash, ensure that there are no hot embers left buried in the ash before you transfer it into a

flammable bin bag.

15 OPERATING IN TRANSITION PERIODS (Summer)

When the outside temperature gets to be more than the temperature within the property, there is a strong possibility

of the flue working in reverse. If the appliance is not lit, this will cause the draught of the flue to travel in a downward

direction and the smell of smoke may be obvious in the room.

If you experience problems lighting the appliance, then it will be necessary to warm the flue before loading the

appliance with kindling. There are various methods for this procedure. Ask your local supplier or registered chimney

sweep for advice.

If the fire is lit, the heat output of the appliance is often reduced and the exhaust gases may not come out the

chimney completely. This can cause them to come back into the room.

In this case:

•shake the embers more frequently,

•increase the air for combustion

•only load a reduced quantity of fuel.

This will help to keep the chimney hot and working efficiently.

Check that all the seals of the appliance are in good order and that the connections to the chimney are also sound.

16 MAINTENANCE - CLEANING THE APPLIANCE

Take great care choosing the products to clean your appliance. A major amount of cleaning can be carried out

using hot soapy water and a soft cloth. Do not leave the appliance surface wet after cleaning; this may cause

uncoated surfaces to go rusty. Using the wrong products on certain surfaces may cause damage to them, so take

care when choosing a cleaner. Never use bleach or chlorine based products, caustic cleaners, paint solvents,

biological powders, coarse abrasives or salt to clean your appliance. Never mix different products as they may

cause a chemical reaction with each other and cause harm to either you or the appliance. Read below to see

specific cleaning techniques. For any further information, please contact your Dealer!

16 A DAILY CARE

To keep the surfaces of your appliance clean, a daily wipe over with a lint free cloth is all that is needed. Clean the

surfaces when the appliance is cool. A wet cloth may be used on certain surfaces, never leave any surface wet after

cleaning as this may go rusty.

To buff the cleaned surfaces, a soft, dry, lint free cloth should be used. Try not to use excessive amounts of water

when cleaning the appliance. Wipe up any spills or condensation streaks as soon as is safe to do so. (i.e. when the

unit is cold) This will prevent the mark burning onto the appliance and becoming a much tougher stain to remove at

a later date, or causing a permanent mark.

16 B CLEANING AND MAINTAINING THE APPLIANCE

The appliances have three main surface finishes; these should be cleaned when the appliance is cool. Please

follow any instructions to the letter for any special cleaning agent that you may use. Ash removal and chimney

maintenance are also important areas to be aware of to ensure the efficient and correct operation of your appliance.

Please read on….

16 C CAST IRON

This can be cleaned with a lint free damp cloth. Don’t leave this surface wet as it will go rusty. If it is cleaned when

the appliance is slightly warm, the damp surface will dry by itself. Otherwise, wipe the surface dry after cleaning.

Another method is to brush the surface with a soft brush. This is good for cleaning in the more detailed and difficult

to get to areas. If cast iron is left for long periods in a damp atmosphere; such as a fireplace; it may start to show

signs of rust. To prevent this, wipe the surface over with light oil. This will burn off when the fire is re-lit.

16 D ENAMELED SURFACE:

These can also be cleaned with lint free damp cloth and then wiped over with a dry cloth.

16 E GLASS CLEANING:

Only clean the glass when the appliance is cold. There are various glass cleaners you can buy at stove shops that

are specially designed to remove hydrocarbon (soot) and fly ash (mineral) deposits from the glass. Follow the

manufacturer’s instructions. Typically, just spray a small amount of cleaner on the glass and use a paper towel or

rag to wipe it clean. Alternatively use a proprietary ceramic hob cleaner such as Hob-brite, as used for ceramic

hobs. Follow the directions on the product. If you break the glass, do not use the appliance until the glass has been

replaced. Contact your dealer to order the replacement glass.

16 F ASH REMOVAL:

The efficient operation of your appliance is dependant on its correct installation, operation and maintenance.

Leaving soot to accumulate inside your appliance will drastically reduce the output of the appliance and prevent it

from doing what it is designed to. Ensure that the ash inside every part of the appliance is removed, not just the ash

pan.

16 G FLUE MAINTENANCE:

Call a certified chimney sweep (National Association of Chimney Sweeps) or other qualified professional to clean

the flue system. These professionals have the equipment and the experience to do a thorough job. The sweep will

advise you as to the intervals that you should have your flue swept. We would recommend that you have it swept at

least twice a year, but you may need to sweep it more.

Get them to inspect the condition of all the associated chimney items and report to you on their condition.

Since coal residue contains sulfur, the metal flue pipe and chimney systems tend to deteriorate much faster than

when burning wood. Be sure to check the pipe at least once every six months to determine if it has corroded.

16 H ROPE SEALS:

For the appliance to operate correctly, it is important that all the seals; where fitted; are in good condition and are

sealing correctly. They should be replaced if they are showing excessive signs of fraying and are not making a good

seal. They are glued into position using a high temperature, flexible, silicone sealant

16 I AIR CONTROLS:

Ensure that all the air controls operate smoothly and are free from ash or other foreign bodies. Pay particular

attention to the damper flap at the rear of the ash drawer. Clean this area with care and ensure that excessive

amounts of ash are kept from building up and affecting the operation of this control.

16 J CLEANING THE CRANKING GRATE.

To clean the mechanism that cranks the grate, just lift out the grate (when cold) and this will expose the rack and

screw. Brush any loose ash from the top of the rack and crank the unit up and down, without the grate in place, to

ensure that the screw is free. Check that there is no soot or other deposits on the inside of the firebox that could

impede the travel of the grate.

Before replacing the grate ensure that all the accumulated ash in both the ash pan and the ash drawer is completely

removed. Failure to clean the ash drawer properly can lead to problems positioning the ash pan and then cause

problems with door closure.

16 J CLEANING THE SMOKE CHANNEL

The area around the oven where the smoke travels will need periodical inspection and cleaning. If the smoke sent

round this area needs to be hot and clean, major deposits around this channel is an indication that the appliance is

not being used correctly. This channel is similar to your chimney, a stiff brush should be all you need to clean it out.

Removing the hob rings will give you access to the top and side of the oven channel. The bottom of the oven can be

removed by taking out the two Phillips screws at the front of the oven base, lift out the base to expose the area

under the oven. If you need to reintroduce the seal around this base plate when re-fitting after cleaning, a high

temperature silicone sealant that withstands temperatures up to 300ºC and conforms to the regulations relating to

its use in areas where food contact is likely.

17 SPARES

THE APPARATUS MUST NOT BE MODIFIED. ONLY USE SPARE PARTS EXPRESSLY AUTHORISED AND

SOLD BY BROSELEY FIRES LTD. CONSULT YOUR LOCAL AUTHORISED DEALER FOR ADVICE.

Broseley Fires can supply an exploded drawing of the components that make up the appliance.

20. INSTALLATION OF THE APPLIANCE

THIS APPLIANCE MUST BE INSTALLED AND COMMISSIONED BY A FULLY QUALIFIED, REGISTERED

ENGINEER.

The guarantee is void if any part of the installation is found to be illegal.

•This appliance must be installed into a ‘Class 1 Chimney’. If there is no existing chimney, then an approved solid

fuel, factory built, prefabricated block type or a twin walled, stainless steel flue can be used. Get advice from a

qualified chimney engineer. Flue sharing is not allowed.

•The flue diameter of these appliances must be a minimum of 5 INCH diameter.

•An adaptor is required for the initial connection. (117mm to 5”) a 4” to 5” adaptor may suffice.

•If excessive draw is present, then a suitable ‘flue draught stabilizer’ should be fitted.

•If the chimney suffers from down draught, then a special ‘anti-downdraught’ cowl will need to be fitted. In exposed

windy locations, a ‘stabilizing’ cowl may need to be fitted. The minimum cowl requirement that we recommend, is

a rain cowl with a bird guard.

•To perform satisfactorily, the chimney height must not be less than 5 meters from stove to cowl. If there are any

bends in the flue, this minimum length will need to be increased by 1 meter for each bend.

•The initial connection to the appliance will need to be 600mm vertical before any bend.

•A soot door will be required to facilitate the sweeping of the flue.

•A maximum of four 45 degree bends is allowed in any complete flue; from stove to cowl.

•Adequate access for sweeping the flue, such as a soot door, must be provided.

•Flue pipe should be fitted inside the flue pipe collar (spigot) to prevent creosote and condensates from running

down onto the top of the appliance. (see specifications for exact collar sizes)

•All flue pipe must be suitable for solid fuel (complies with latest European regs.) and fitted in accordance with

building regulations, whilst complying with current legislation and manufacturers’ instructions.

•If a rear flue is able to be fitted, the horizontal length must be no longer than 150mm.

•If there is additional ventilation in any room, this will create air depression and the risk of the products of

combustion being drawn into the room Mechanical ventilation in the same room as any solid fuel appliance must

be avoided.

•This appliance should be connected to an open vented system in line with building regulations and any other

regulations that are in force at the time should be observed.

The use of this equipment as a stove only is not recommended. For no region should the stove be lit before

it has been filled with water. To attempt this could result in serious damage.

21 FLUE REQUIREMENTS

This appliance has a European sized flue collar that is metric in size. An adaptor is required for the initial connection

to the flue collar. The adaptor for this appliance will be a standard 5 to 6 inch adaptor. This appliance requires a

minimum flue diameter of 6 inches. The draw of the chimney should be at least 17 Pa (1.7mm H2o) The

measurement must always be done when the stove is hot (producing nominal heat values). When the pressure

exceeds 20 Pa (2.0mm of a column of water) it will be necessary to reduce it by the addition of a flue draught

stabilizer.

Installation, construction, and maintenance of chimneys and flues must comply with Building regulations ‘Approved

Document (ADJ)’ Any domestic solid fuel appliance will only work efficiently when connected to a chimney system

capable of generating adequate up-draft to induce sufficient air supply for complete combustion and to overcome

any friction resistance association with the system. The chimney is one of the most important parts of the

installation; great care should be given to its design. The chimney must be thoroughly swept, checked for

soundness and suitability, before any connection is made to the appliance. This must be carried out by a qualified

person. If re-using an existing flue, the flue and the chimney should be checked and if necessary, altered to ensure

that they satisfy the requirements for the proposed use. Lining a defective flue is an option.

22 LINING THE FLUE

An independently certified flexible metal liner can be used to reline a chimney. An insulated chimney is the most

efficient and safe way to burn wood and coal.

Tar deposits condense in a cool chimney. An insulated chimney helps prevent these deposits.

A standard chimney will gradually get saturated in tar, this is a fire hazard.

Tar stains may appear on the surface of the chimney breast inside the property.

23 FLUE TERMINATION

The height and termination of the flue is an important

part of the installation and consideration needs to be

made to ensure that the flue is high enough to create

sufficient draft to clear the products of combustion.

The termination of the flue outlet position which can

meet the requirements in common circumstances are

shown in Document J. If there are unusual

circumstances that will affect the efficient and safe

removal of the products of combustion; the height

and/or the separation distances shown in Document J

may need to be increased.

24 PROVISION OF A NOTICE PLATE

A notice plate must be durable and be fixed on site, where a hearth, fireplace flue or chimney is provided or

extended (including cases where a flue is provided as part of refurbishment work). Building regulations states that

the responsibility for achieving compliance with the requirements of Part J rests with the person carrying out the

work and so this person must be competent in the work they are being asked to do.

25 SITING THE APPLIANCE

This appliance must not be fitted into a location where it will be impossible to service.

The location must comply with the requirements laid down in the Building Regulations.

26 HEARTH REQUIREMENTS

It is essential that the hearth / base on which the appliance will stand is strong enough to support the weight of the

appliance and the chimney / flue. In certain circumstances, it may be necessary to support the flue pipe with

brackets. The hearth must be level and made of a suitably robust, non combustible material.

The positioning of the appliance and dimensions of the hearth must comply with current building regulations.

This appliance does not cause the hearth to exceed 100º C.

Manufacturer’s instructions relating to clearances must be adhered to.

•The thickness of the wall needs to be at least 75 mm

•The height of the wall needs to be at least 1.2m above the hearth.

PLEASE REFER TO BUILDING REGULATIONS “WALLS ADJACENT TO HEARTHS”

for further information on this subject.

28 ADDITIONAL VENTILATION

There must be sufficient free air for combustion into the room where the appliance of 5Kw or more is installed. THIS

IS A LEGAL REQUIREMENT.

Permanent openings or vents must not be covered. Vents needs to be positioned carefully, they must be protected

from direct wind conditions. A baffle that has been specially designed to fit over the vent will protect it from the

effects of wind, but must not restrict the total vent area and must be secured in a way that prevents its movement.

Regular inspection of any vents is critical to ensure that the vent has not become restricted.

The appliance may require up to 20 m3/hour of combustion air. The natural recirculation of air must be guaranteed

by having permanent ventilation to the outside.

An extractor fan, cooker hood or similar product, installed in the same room, or in a room nearby; that sucks air out

(aspirating); may negatively affect the functions of your appliance.

If the room contains more than one appliance; of the type that requires combustible air; a calculation will need to be

made to re-calculate the permanent air vent requirement.

Please see the ‘Technical Data’ list at the front of these instructions or refer to current building regulations for fixed

additional ventilation requirements.

29 CHIMNEY FIRE

If a chimney fire occurs in the flue or the chimney:

1. Immediately shut off the air supply by closing all dampers and air openings on the stove.

2. Ensure the main door and ash door are securely closed.

3. If the fire in the stove or fireplace can be extinguished safely; with a CO2 extinguisher; put it out as quickly

and safely as possible. Do not attempt to put out the fire using water.

4. Close all windows and doors to the room.

5. Call the fire brigade

When the chimney has stopped burning have it checked by a specialist for possible cracks or leaks.

Please review the way you are using the appliance and check that the fuel you are using is suitable. Chimney fires

only occur if the appliance has been wrongly installed , maintained or operated. Damage caused to an appliance

where a chimney fire has occurred are not covered by any guarantee.

•Please comply with the technical data given in this instruction manual.

•Illegal installations are not covered by any sort of guarantee.
