PLEASE READ THESE INSTRUCTIONS THOROUGHLY BEFORE INSTALLING,

OPERATING OR SERVICING THIS APPLIANCE.

Congratulations on buying a product distributed by Broseley Fires Ltd.

INTRODUCTION

Please read the following instructions carefully to get the best from your new purchase.

The keys to safe, successful and efficient wood burning are good planning, correct installation (by a qualified

heating engineer) and proper operation.

Modern homes have better levels of insulation and are more energy efficient, with more effective and better seals

on doors and windows. This makes our homes easier to heat, but also means that solid fuel appliances must be

more carefully designed so that they will function correctly in the energy efficient, modern homes of today. The

more energy efficient a house is, the less fuel is required to heat it. Less fuel use means less impact on the

environment.

The operation of our appliances, so that they do not produce excessive smoke (beyond the initial light up and

reloading periods) is most important. When our appliances are not smoking, it is an indication that they are being

operated correctly and are burning efficiently. The escape of any unburnt particles and some gases into the

atmosphere are the cause of air pollution.

Our appliances are designed to ensure that the combustion of all gases and particles takes place within the

firebox, to maximise the heat output of the appliance and to minimize the discharge of particulate emissions to the

atmosphere.

It is important therefore, for appliances to be operated in accordance with our instructions in a manner that

maintains a high temperature in the firebox with an adequate supply of air to ensure efficient combustion. A good

indication of efficient combustion is a bright lively flame in the firebox. A dull flame or smoldering fire indicates

poor or incomplete combustion.

To maintain adequate heat in the firebox, it is very important to use dry, well seasoned wood with less than 20%

moisture content. The wood must be correctly sized for the particular appliance and it also helps to have at least

three or four pieces burning at the one time to assist the combustion process.

Adding single pieces of unseasoned or wet wood to a fire will reduce the firebox temperature and prevent

adequate combustion. This will result in increased smoke emissions causing the flue and internal components of

the appliance to become blocked with tar and creosote more quickly. The tar and creosote deposits in the

chimney will fuel a chimney fire.

Please note that it is a requirement under the Broseley Fires Ltd’s warranty system that the

installation of the stove is carried out under 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.

A “Declaration of Completion” Certificate must be obtained for the installation and retained by the end user.

Failure to comply with these requirements may void the warranty.

PLEASE READ THESE INSTRUCTIONS THOROUGHLY BEFORE INSTALLING,

2. GENERAL DECLARATION

Subject: Asbestos and cadmium

It is declared that all our products are assembled with materials that do not contain any asbestos or its derivatives

and that the materials used for welding do not contain cadmium in any form.

Subject: Regulation CE no. 1935/2004

It is declared that in all our products the materials that are destined to come into contact with foodstuffs are

adapted to food use in line with the above regulation.

Our responsibility is limited to the appliance. It is the responsibility of the purchaser to ensure that the installation

is carried out in accordance with building regulations.

We are not liable for any product modified without authorisation nor if any non original spare parts are used.

3. KEY ENVIRONMENTAL CONSIDERATIONS

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

and operate 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.

4. TECHNICAL DESCRIPTION

These appliances have been developed to burn wood at a very efficient rate. The figures quoted here are from

test firings using beech logs with a moisture content of less than 20%.

The appliance is engineered using the latest manufacturing techniques and modern computerized machinery.

On some of the appliances there is a surround option. These are in various finishes including Italian ceramic tiles

and genuine soapstone finish. Soapstone is a soft-textured stone that possesses fantastic heat-retaining

properties. The absorbent stone holds heat extremely well. Even after the fire has gone out, warmth radiates from

all stone surfaces, ensuring an even, long-lasting heat supply. Another finish that’s available is a glass finish that

gives the appliance a modern contemporary look.

5 THE ‘AIR’ CONTROLS

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

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

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.

The air controls are as follows:

•PRIMARY AIR CONTROL

•SECONDARY AIR CONTROL (AIR WASH)

There is a control for the ‘standard’ ventilator fans. See chapter 15 for details.

5 A THE PRIMARY AIR CONTROL see FIG.1. 1 A + 2A

The primary air control is found on the front of the appliance, just below the glass door on the left hand side; it is

in the style of a pull-push lever. This allows air to enter from below the grate across the ash drawer. To open the

control pull the lever towards you, to close it push it in. This control is used mainly when lighting the fire.

The ash drawer and chamber must be regularly emptied, so that the ash does not obstruct the entry of primary

air.

5 B SECONDARY AIR CONTROL (pull-push lever) See FIG.1. 2A

The ‘secondary air control’ is also in the style of a pull-push lever. This is found on the front of the appliance, just

below the main loading door on the right hand side.

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’. The air 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.

This control will be used when the fire is fully established. When the lever is pushed in it is open, to close, pull it

out.

FIG. 1

6 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 IN USE. PLEASE ENSURE THAT CHILDREN, THE ELDERLY

AND THE INFIRM ARE MADE AWARE OF THIS

•Serious damage can 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 controls.

•Never burn enhanced fuels such as ‘Petrocoke’

•Do not overload the appliance with fuel.

•Never use flammable chemicals or fluids, such as gasoline, 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.

•If you regularly run the appliance at a very low output, you will need to have the flue cleaned 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.

7 FUEL OPTIONS

These appliances have been developed to burn wood. The results quoted in our literature are from test firings

using beech logs with a moisture content of less than 20%. Coal should never be burnt in these appliances

7 A BURNING WOOD

Hardwoods have a far greater calorific value than softwoods, weight for weight. Any wood needs 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.

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 always possible to keep the stove in overnight. SEE BELOW (maintaining a wood fire)

8 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.

During the first lightings, nothing should be leant against the stove and in particular on the varnished

surfaces. The varnished surfaces must not be touched during the initial curing process.

10 LIGHTING AND MAINTAINING A LOG FIRE

•Use scrunched up paper and dry kindling to start the fire. An alternative is to use fire lighters.

•Open the primary and secondary air controls to the fully open position. It will take a short time for the fire

to establish itself.

•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, 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.

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

out the door.

•A typical load will be 2 KG; this will maintain the output of this appliance

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

•It is not necessary to riddle the ash using the ‘riddling grate’ as wood burns best on a flat surface.

•

11 ASH REMOVAL – CLEANING OUT THE ASH

The removal of the ashes should be done when the appliance is cold.

When you burn logs, 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, i.e. Softwood & hardwood; 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.

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.

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. Use a metal container to carry any ash.

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

12 WOOD 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, so apply it appropriately for your soil.

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. Use the same precautions as disposing of coal ash.

14 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 will be obvious in the room.

If you experience problems lighting the appliance because of the greater outside temperature, 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 and

•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.

15 STANDARD VENTILATOR OPERATION

The appliance comes with a pair of fans just below the main door. This is where the air is drawn in, not where it is

blown out. After you have lit the appliance, the hot air that is generated; between the inner and outer casing; can

be vented either out of the front vent on the appliance (above the door) or up the ‘additional warm air vents’, The

Inserto 50 does not have additional air vents. see chapter 26.

The standard ventilator has three speeds. OFF – LOW – HIGH.

FIG. 2 shows the three position slider switch.

FIG. 2

15 A DEFLECTOR OPERATION

To divert the hot air either up the vents or into the room, there is a deflector that needs to be operated. Please see

FIG. 4 A and 4 B to see the position of this item. Use the supplied operating tool to position the deflector either

vertically, to distribute the hot air up the ventilation tubes; or horizontally, to have the hot air exiting the appliance

from the vent above the door.

FIG. 4 A FIG. 4 B

16 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….

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

carried out using hot soapy water and a soft cloth. Using the wrong products will cause damage to its surfaces.

Never use bleach or chlorine based products, caustic cleaners, paint solvents, biological powders, coarse

abrasives or salt.

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 the more stubborn stains, a mildly abrasive cleaner should be used, such as ‘Astonish’.

This is safe to use on enamel surfaces. Do not use Astonish on the chrome components.

For any further information, please contact your Dealer!

16 A DAILY CARE

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

needed. A wet cloth may be used on certain surfaces. Try not to use excessive amounts of water when cleaning

the appliance. To buff the cleaned surfaces, a soft, dry, lint free cloth should be used.

16 B CAST IRON

This can be cleaned with a lint free, damp cloth. Do not leave this surface wet. 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 C 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. The directions for use on the bottle are to turn the appliance off, apply

cleaner with paper towel or clean cloth, rub the glass lightly, rinse residue and dry the glass with a paper

towel/soft clean tissue.

If you only burn logs in your appliance, then you can dip a damp cloth in the ash and use this to scrub the glass

clean. Do NOT use this method if you use coal, as the ash produced is too abrasive.

16 D BROKEN GLASS

The glass in the fire door is ceramic and is resistant to sudden temperature changes up to 750 degrees

Centigrade. Breakage can only be caused by mechanical shock (collision, violent damage etc) because of this,

replacement is not covered by the guarantee.

16 E 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. Ash will settle on top of the baffle and this is an area that will also need periodic inspection.

16 F 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 G 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 H SOAPSTONE

Allow the soapstone to cool to room temperature on its own before cleaning. Rinsing with a sponge and hot water

is usually sufficient to clean soapstone.

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.

17 SPARES

THE APPARATUS MUST NOT BE MODIFIED IN ANY WAY.

ONLY SPARE PARTS EXPRESSLY AUTHORISED OR SOLD BY BROSELEY FIRES LTD. MAY BE USED.

CONSULT YOUR LOCAL AUTHORISED DEALER FOR ADVICE.

18 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 is 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.

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.

Because of nature of this type of appliance, it is not possible to give step by step fitting instructions for the

appliance. Please read the following advice before starting any work and make the necessary pre-installation

checks.

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. A standard (imperial sized) adaptor with a crimped leading edge will allow the flue to

fit inside the flue collar of the Inserto 80 & Inserto 100.. Please refer to the diagrams and tables below for further

details.

22 FLUE AND CHIMNEY GUIDANCE

•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 minimum flue diameter for Inserto 80 & 100 must be Ø150mm and Ø125mm for the INSERTO 50.

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

•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 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.

•Mechanical ventilation in the same room as any solid fuel appliance must be avoided.

Further instruction on the installation of the ‘additional warm air vents’ can be found in chapter 22.

These allow the warm air to be piped into the room in which the appliance is sited. With the installation of the

deluxe ventilator kit; which comprises of a more powerful fan; the warm air can be vented further down the

additional warm air vents.

The natural up-draft on a chimney will depend on a number of factors. The chimney is one of the most important

parts of the installation; great care should be given to its design.

The draw of the chimney should be at least 12 Pa (1.2mm of a column of water). The measurement must always

be done when the stove is hot (producing nominal heat values). When the pressure exceeds 17 Pa (1.7mm of a

column of water) it will be necessary for the installation of a flue draft stabilizer. The flue draft measurement is

critical and MUST be measured. If incorrect, the appliance will NOT operate correctly and damage may occur.

22 A LINING THE FLUE

An independently certified flexible metal liner can be used to reline a chimney. A chimney liner should be installed

in accordance with Building Regulations Part J, reference should also be made to the manufacturers instructions.

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, unlined 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.

22 B 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 and a

special cowl may need to be fitted to help correct

the issue.

22 C 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). ADJ 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. The completed flue must pass the

appropriate tests that assess whether the flue in the chimney, the connecting flue pipe (and flue gas passages in

the appliance) are free of obstruction and acceptably gas tight. In addition, appliance performance tests, including

flue spillage tests should be carried out when an appliance is commissioned.

23 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. Minimum clearances within these instructions must

be complied with.

23 A HEARTH REQUIREMENTS

The positioning of the appliance and dimensions of the hearth must comply with current national and local

building regulations and be at least the minimum sizes shown in the diagram below See FIG 9.

If the appliance is fitted into a setting that raises it further above the hearth than the minimum dimension shown in

FIG xxx, consideration must be given to the depth of the hearth in front of the appliance. The higher up the wall

that the appliance is located, the deeper the hearth will need to extend in front of the appliance. This will hopefully

prevent any combustible materials from falling outside the perimeter of the extended hearth.

23 B STOVE CLEARANCES

X = DISTANCE OF APPLIANCE ABOVE SURFACE OF NON COMBUSTIBLE HEARTH.

STOVE CLEARANCES TO NON - FLAMMABLE MATERIALS

B = X + 300mm (up to a maximum of 900mm)

C = X + 200mm (up to a maximum of 400mm)

STOVE CLEARANCES TO FLAMMABLE MATERIALS

•The minimum distance from any flammable object, or one that is sensitive to heat, (furniture, wood, fabrics. etc.)

and from materials with flammable structure, must be 200 mm to the rear and 200 mm both sides.

•In front of the appliance there must no flammable object or building material sensitive to heat within 1000mm.

•Above the appliance, there must not be any flammable items within 630mm.

24 VENTING THE HOUSING

To allow an air loop inside the appliances location, it is necessary to have an air entrance vent hole (position A)

below the appliance and another vent above the appliance. (position B)

The intake vent (A) air can be drawn in from the room in which the appliance is installed, or directly from outside.

Obviously, air directly from outside will tend to be cooler.

To ensure the correct and safe operation of the appliance, when building the housing in which the appliance will

be located, it is necessary to respect the clearances between the insert and the inner walls of the housing.

Considering the measurements given in the technical specifications, you need to account for at least 60 mm of air

space above, behind and on the two sides of the appliance.

It is critical that the chamber in which the appliance is located is well ventilated with ENTRY & EXIT vents.

There is a requirement for a 60mm gap down each side, behind and above the appliance. This will allow

the chamber to breath and prevent the build-up of hot air that could cause damage to the housing.

The gap generated between the top edge of the appliance and the housing will be less.

The minimum recommended distance here is 5mm.

The void behind the appliance, down each side and above it will be 60mm, as shown in the diagram above.

25 ADDITIONAL fixed VENTILATION (to aid combustion)

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 40 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.

26 ADDITIONAL WARM AIR VENTS

The Inserto 80 and 100 models have additional features. They are equipped with a fan to improve the flow of the

convected heat from around the body of the stove into the room. ‘ADDITIONAL WARM AIR VENTS’ may be

added to the appliance to allow the venting of warm air to a maximum pipe length of 1.5 meters; when using the

‘STANDARD’ ventilator; and 4 meters when the ‘DELUXE’ ventilator has been fitted. The Deluxe ventilator can be

purchased as an additional item. When switched on, a variable thermostat will adjust the temperature at which the

fans come into operation. This should be installed by a qualified electrician and compliance with current

regulations must be observed. Or the fan can simply be switched on when desired.

A further feature of these models is the provision of further vents if required via two blanked outlets on the top of

the body of the stove see Figure 4, below.

The vents should be connected to the body of the stove using fire resistant pipe of ø150mm. The blanks on the

top of the stove will need to be removed and the collars provided should be screwed into place to enable the

hoses to be securely clamped in place.

Each pipe should not exceed 1.5m in length unless forced ventilation; the ‘DELUXE VENTILATOR’ is used; in

which case they can be up to 4m long. If this is required, the optional ‘deluxe’ ventilation kit should be fitted. For

details see the technical drawings below. (see appendix B)

27 ISOLATING PLUG POSITION (For the ‘standard’ fan)

The picture to the left shows the isolating plug that has a possibility

of two positions. It is found on the printed circuit board inside the

control box of the ‘standard’ ventilator kit. If the appliance being

installed is the MODEL 50, then the plug needs to be fitted onto

the two left hand pegs.

The picture here shows the plug on the two right hand pegs, this is

suitable for the MODEL 80 and the MODEL 100.
