9 RECOMMENDATIONS FOR THE EXECUTION OF THE HYDRAULIC AND ELECTRIC SYSTEM

Installation must be done by a competent person, namely HETAS H004 qualified.

Before installing your central heating cooker we recommend that your flue outlet has a suitable

draught.

We recommend connecting the plant circulating pump to the central heating cooker’s control

panel.

We recommend installing non-return valves to prevent natural circulation phenomena

between the central heating cooker and the plant (see drawing par. 4.5 - 4.6 - 4.7 - 4.8 ). The
presence of open boilers causes natural circulation on the water surface with subsequent
oxygenation of the water. The presence of natural circulation produces condensation and can
consequently cause corrosion to parts of the central heating cooker.

We recommend you earth the central heating cooker and check the efficiency of the earthing
of the electrical system to which the central heating cooker is connected.

We recommend a magnetic cleaning system to make sure system fluid is optimum for

maximising performance and lifespan of product

Water treatment equipment is needed when: mains water has a hardness higher than

100mg/ml, this can be checked with your local water supply company or if private supply you
will need to check its quality.

Fitting a 3 way mixing valve (see below) to minimise condensate corrosion is mandatory, this

ensures the return water going into boiler is above 55c which drastically reduces the quantity of
acidic corrosion and therefore increases the lifespan of the product.

Minimum water pressure of 0.2 bar is needed

The safety heat exchanger cannot be used to produce domestic hot water

The appliance cannot be used “dry” i.e. with no water in it.

Care must be used when using a mixing system with alternative heat sources that do not allow

the bosky to be shut down which would cause the wood fuel to stew and cause multiple
problems such as mentioned in the fuel guide.

THERMOROSSI DECLINES ALL RESPONSIBILITY FOR THE CORRECT FUNCTIONING AND

DURATION OF THE APPLIANCE IF ALL OF THE ABOVE GUIDELINES ARE NOT
OBSERVED. NO TECHNICAL SERVICING BY OR ON BEHALF OF THERMOROSSI,
CAUSED BY THE NON-OBSERVANCE OF THESE RECOMMENDATIONS, WILL BE
COVERED BY WARRANTY.

ADVISORY; The values above (for the 25 & F25 and the 30 & F30) were obtained by using beech wood
in logs (9 logs) with a total weight of 7.2kg, their length was 400mm and the calorific value was
4104kcal/kg and the moisture was 12%. Using wood with different specifications to this will directly affect

performance, efficiency, ash formation, glass cleanliness and general dirtiness. The values above (for

the Country & Country F) were obtained by using beech wood in logs (9 logs) with a total weight of

7.6kg, their length was 400mmn and the calorific value was 4104kcal/kg and the moisture was 12%.

Using wood with different specifications to this will directly affect performance, efficiency, ash formation,
glass cleanliness and general dirtiness.

2.1VITRIFICATION

The central heating cookers series 25 - 30 - F25 - F30 country, country F-can be
supplied with the boiler body with vitrification treatment. This treatment occurs at very

high temperatures that permit the glass and steel to melt into an alloy that is completely
impervious to corrosion attack caused by acid combustion smoke. Vitrification protects the boiler body
from corrosion caused by acid smoke and condensation developed by the combustion of the wood
fuel. The presence of surface defects such as indents, scratches, etc..., do not affect the life or
resistance of the corrosion proofing treatment. THIS GIVES THE BOILER BODY AN 8 YEAR
GUARANTEE

3GENERAL DESCRIPTION

3.1OPERATING PRINCIPLE

•Your central heating cooker has been constructed to satisfy all your heating and cooking needs.

3.2THE FUEL

CORRECT use of appliance when using wood fuel

For anyone interested in wood burning, there is much to learn; in the following text you
will find guidance and information on the subject.

Before installing or using a wood burning appliance, carefully read the manufacturers
installation procedure or if you are in any doubt as to the soundness of your chimney, call us and we
will be pleased to advise you. ALL WORK MUST COMPLY WITH CURRENT BUILDING
REGULATIONS.

The first few firings will if done correctly leave a light coating of ash on the flue pathways this will
minimise the risk of tar build up – therefore it is critical these firing are done as best practise and a hot
clean fire is established.

Remember that on the initial light up of the appliance, large amounts of water may run from the
appliance, this is quite normal and caused by massive condensation due to the fact that the boiler is
clock cold and the newly established fire is hot.

Maximum temperature difference = maximum condensation.

Once the water temperature in the boiler starts to increase the temperature difference starts to
decrease and so does the initial condensation.

Good woodburning technique

If wood is burned at high temperatures a more complete combustion occurs, complete combustion
means that most of the volatile hydrocarbons locked in the wood are released in the form of heat
generally displayed as long yellow flame combustion.

The higher the combustion chamber temperature, the more complete the combustion process.

Bad wood burning technique

If wood is burned at low temperature then very little is achieved and incomplete combustion occurs.

Incomplete combustion is typified by wood tar deposits all over the internals of the firebox, flue ways
and door glass.

The lower the combustion chamber temperature, the worse the combustion and the greater the build
up of wood tar.

In really bad cases, wood tar can drip from the appliance.

 GOOD wood burning technique increases the efficiency of the burn process.
 BAD wood burning technique decreases the efficiency of the burn process.
 GOOD wood burning technique decreases your running costs.
 BAD wood burning technique increases your running costs.
 GOOD wood burning technique increases the life expectancy of the boiler.
 BAD wood burning technique decreases the life expectancy of the boiler.
 GOOD wood burning technique results in a clean appliance and chimney.
 BAD wood burning technique results in a tar covered appliance and chimney.
 Below is an example of tar build up that caused excessive damage when the chimney

caught fire – totally preventable!

loading and running the appliance

The fire is ignited in the usual way and air is automatically admitted through the air inlet flap controlled
by the relevant setting of the thermostat knob.

When the fire is established, build it up slowly by adding a small quantity of wood, take care not to put
too much wood on at once otherwise this will;

Kill the fire.

Reduce the firebox temperature.

Create smoke.

Cause tarring.

Cause condensation.

When the combustion chamber is up to a high enough temperature, the wood oil starts to vaporise
from the wood, and creates long yellow flames.

Secondary air is drawn in to mix with these flames and this further improves the combustion.

As the wood fuel burns away it slowly decomposes leaving a light grey coloured ash.

As is the case with all fires, if it is allowed to die down too much, it will not be possible to recover it.

Try to keep topping the firebox up regularly but do not overload it so as to kill the temperature of it.

If you need to keep the appliance in for longer periods of time such as overnight ‘banking’ try
topping it up with smokeless fuel otherwise let it go out and re light it. If it is filled up
completely and the air is shut down then it will stew and only leave damaging deposits of tar
both in the firebox and the flue.

ABOUT WOOD FUEL

Do I know how much wood I will need to burn?

Roughly 1 lb of wood equals 1Kw of energy; therefore if you need 30Kw of energy per hour you are
going to have to burn about 30 lbs of wood per hour.

Pine and Oak have different density therefore a tonne of Pine will take up substantially more volume
than a tonne of Oak.

If you work out how many Kilowatt hours are required to keep your property warm then you should be
able to work out the weight of wood required for a seasons heating.

Do I have a reliable and proven supplier of wood and do I know the cost?

Once you have established your seasons requirement you can order your supplies from a local wood
fuel supplier.

Do I know how to store the wood?

Before any wood is burnt, it should have a moisture content of no more that 20%.

This can be achieved by drying outdoors for 12 months and then under cover for the second 12
months assuming that the wood has been cut, split and stored in such a way as to allow adequate air
to circulate through the wood pile.

Ash is an exception to this rule as it can be cut early in the year and (providing it is stored correctly)
burned in the autumn.

Equipment to help me get the best from my wood burning appliance

There are many factors which will affect the running of your wood burning appliance but the most
common problems are:-

WET WOOD

RUNNING THE APPLIANCE AT THE WRONG TEMPERATURE

INCORRECT INSTALATION

INCORRECT CHIMNEY

The main problem here is knowing

How do I know that the wood fuel is at the correct moisture content for burning?

How do I know if I am burning the wood at the correct temperature?

Two pieces of equipment will help here, a moisture meter will tell you what the moisture content of
your wood is and a flue thermometer will tell you what temperature your appliance is running at.

Both of these are available from us.

COAL

If you wish to burn ordinary house coal on a central heating stove or boiler you need to know how to
do it, and that the stove or boiler you use has the necessary design features.

Recommended solid fuels
Manufactured - sunbrite singles, sunbrite doubles, coalite, phurnacite and supacite. Natural ­anthracite large & small nuts, selected housecoal (trebles/large nuts and doubles/nuts), taybrite, coke.
Oversize fuel lumps should be broken down to size. Stones and other foreign bodies should be
removed when fuelling.
Fuel should be stored under cover and ventilated, particularly manufactured fuels which must be kept
dry. Wet kitchen refuse should not be burned.
Avoid excessive fire temperatures with solid fuel - they are unnecessary and may do serious harm to

the cooker. The first symptoms of an overheated cooker is the formation of clinker (melted ash) which
will damage the fire bricks.
Damaged firebricks should be replaced as soon as possible but may be temporarily repaired with fire
cement.

The main problems are nearly always caused by: ­Putting too much coal on a fire which is almost out and then opening the ash pan door to increase the

draw. If you put masses of coal on a low fire and then open the bottom ash access door or the water
temperature thermostat, the result will be that the fire will produce too much smoke which cannot burn
or which when it bursts into flames will cause a small explosion in the firebox and also up the
chimney, the latter being particularly dangerous.
Running the appliance at too low a temperature causing the fire to smoulder continuously.
Not riddling the fire often enough so preventing the required amount of combustion air reaching the
fire.
The name of the game is to keep your fire burning healthily. Build it up with small amounts regularly
rather than large amounts infrequently and use coal no smaller than doubles. Cobbles are better
because they allow plenty of air to get around the firebox.
When loading the fire with a fresh change of coal, if it is possible rake the hot or glowing embers to
the front of the firebox and put the new coal to the back. In this way the new coal will burst into
flames more quickly and the bright embers will encourage the smoke to ignite quickly.
Slack, shale, singles or small fuel will simply stop air getting through and cause the sooting and
exploding problems, which are to be avoided. Regular riddling is of prime importance, as mentioned
earlier.
If you get it wrong you will normally do it in the first week or month. In some cases the result can be a
blocked chimney in less than a week. The part of the chimney, which blocks up first, will be the pipe
connecting the cooker to the chimney. This pipe must be as near vertical as possible for coal burning.
Rear outlet flues or bends are to be avoided at all costs, according to building regulations the
minimum angle a flue pipe can run is 45 dg., although we think a minimum of 60 dg is better.

Regular cleaning of the appliance and the chimney is essential the frequency of such cleaning would
be established by experience but we would think once every 6 weeks would be adequate.
A carbon monoxide alarm must be fitted in the same room as the cooker

4INSTALLATION
It IS MANDATORY THAT ONLY A COMPETENT PERSONS SCHEME REGISTERED INSTALLER

IS USED IN ENGLAND, WALES AND SCOTLAND.

4.1 LOCATING THE CENTRAL HEATING COOKER
A vital aspect to consider is that the flooring of the room in which the central heating cooker is
installed must be capable of bearing the weight of the central heating cooker.

For Country, Country F - Ensure that there is always a minimum 200mm safety gap between the
central heating cooker and combustible materials at the sides and rear. Adhere to the recommended
minimum distances illustrated in the drawing below.

For the Bosky 25, 30, F25 & F30, side distances need only to be 75MM.

For inset installations ensure that the top cast iron cornice is insulated from the surrounding
furnishings by means of lateral air spaces or compressed vermiculite insullation board or similar non­combustable matieral.

On the country models the flow and return pipes are only available with rear connections because of
the ceramic panels as opposed to left hand or rear choice on the Bosky. Also the vintage models are
slightly wider (70mm) as the panels are convex (shown below)

4.1.1 INSET CENTRAL HEATING COOKER

If you wish to integrate your central heating cooker with your kitchen furnishings or
with a particular furnishing arrangement remove the fold-away towel rack by undoing

the 2 screws as illustrated in the figure below and then mount the enamelled casing
(only for models 25 - 30 - F25 - F30 ) . It is also advisable to apply 75mm spacers to the sides of
the central heating cooker to prevent the heat from the top cast iron cornice from damaging the
adjacent furniture.

4.2 MOUNTING THE SAFETY HEAT EXCHANGER (OPTIONAL) 25 - 30 - F25.F30)

To install the safety heat exchanger remove the vertical door, the left side together with its insulation
and the vertical upright that holds the door together with its screws as indicated. Slide in the heat
exchanger (1) and secure it to the boiler using the hardware (2) provided. Close the hole with the plug
(3). By installing a thermal relief valve the excess heat is absorbed as soon as the central heating
cooker rises to excessive temperature values due to external causes. This function is called fast
disconnection phase.

MOUNTING THE SAFETY HEAT EXCHANGER (OPTIONAL) Country, Country F
This must be carried out by removing the ceramic left handside panels ( acting as indicated in par .

4.13) .
Remove the cap ( 10 ) by turning the screws ( 7 ) and its washers ( 8 ) . Now attach the heat
exchanger ( 1 ) and accessories ( 2 ) ( 3 ) ( 4 ) ( 5 ) to the cooker . Now attach the two curves
provided ( 6 ) to exchanger then connecting the same to a safety relief valve linked to mains water . In
this way it absorbs the excess heat

By installing a thermal relief valve the excess heat is absorbed as soon as the central heating cooker
rises to excessive temperature values due to external causes. This function is called fast
disconnection phase

PLUMBING INFORMATION

Primaries must be 28MM minimum. Flow and return pipework must be 22MM minimum.

The key feature of this layout is the injector tee, which allows primary gravity circulation to occur when

the pump is not running and induced gravity flow to occur when the pump is running.

To reduce the necessity of running four pipes from the boiler, it is possible to fit the injector tee at first

floor level and then to fit a flow and return only to the boiler connected diagonally as shown.

In case of electrical failure it is essential to allow at least 25% - 30% of the boiler output, to be
available as a form of gravity heat leak. This can be achieved by fitting radiators teed off the primary
circuit, as illustrated in the diagram

4.7 GUIDELINES FOR THE HYDRAULIC CONNECTIONS OF THE CENTRAL HEATING COOKER TO THE BOILER
COILS.

Thermal stores can be designed to integrate a variety of different heat sources and allow both hot

water and central heating to be carried out at maximum economy.
The size of the store is determined by the heat load of the property and hot water flow rates required.
In the illustration, the solar coil is used to provide heat into the thermal store, which can be used for

hot water production and as a contribution to central heating.
The wood stove, open vented oil or gas boiler, and immersion heater are all optional.
If unvented appliances are used a different version of the Thermal store can be used but this would

preclude the optional wood stove, if a wood stove option is required then the vented Thermal Store

must be used and it would require fitting on the floor above the wood stove as heat from the stove

must reach the store via natural gravity flow.
Depending upon the output of the wood stove boiler and the capacity of the store, it may also be

necessary to fit a heat leak radiator on the hot flow to the store.
Hot water for domestic use is provided via heat exchange from the large coil, with the correct size

heat sources, flow rates of up to 25 litres per minute can be achieved.

Note that the under floor option uses a sealed system as opposed to a vented system to stop cross

contamination from the other heat sources

5.2 LIGHTING AND STARTING THE CENTRAL HEATING COOKERS
Before using the central heating cooker make sure that all the movable parts are in

position; also remove any labels and stickers from the glass to avoid having
permanent traces remain on the surfaces. Verify that the hydraulic and electric

connections have been made perfectly.

REMOVE THE PROTECTIVE ADHESIVE FILM FROM THE COOKTOP.

To start the central heating cooker firstly activate the starter by lifting the pin until it hooks onto the
plate by means of the groove on it (see fig.above and on page F - 9 ; use the tool provided). Leave
the adjustment ring I - 14 open. Now make a small fire using paper or cardboard together with wood
chips or small pieces of wood, and keep adding bigger pieces of wood as the fire gets going. When
the combustion is well underway, turn the starter F - 9 to the home position and close the adjustment
ring I - 14.

CAUTION: DO NOT FORGET TO CLOSE THE ADJUSTMENT RING! IF IT IS LEFT
OPEN THERE IS A SERIOUS RISK OF THE BOILER OVERHEATING AND
SUBSEQUENTLY DAMAGING THE BOILER ITSELF. THIS DAMAGE IS NOT

COVERED BY WARRANTY AS IT WOULD BE THE RESULT OF NEGLIGENCE BY THE
USER. IF THE STARTER IS LEFT OPEN THE RESULT IS LESS HEAT TRANSFER TO THE
WATER IN THE CENTRAL HEATING COOKER AS THE ADDITIONAL HEAT EXCHANGER IS
NOT UTILISED.

5.3 OPERATION OF THE CENTRAL HEATING COOKERS

It must be noted the temperature gauge on the oven door reads 20c less than the interior
temperature of the oven and when the door has been opened it might drop, but this does not
reflect the interior temperature which regains its temperature quicker than the thermometer

Once the heater has been lit and started, the combustion can be increased or reduced by acting on
the automatic combustion air thermostat adjustment knob to adapt the central heating cooker to your
heating or cooking needs. The heating pump starts up as soon as the anti-condensation thermostat
calibrated at 60°C gives the start signal to the plant circulating pump.
The maximum thermal value is achieved by using fuel having a diameter of 5-7 cm , obviously bigger

pieces can be used but at the expense of less power. To rekindle the fire move the grate to
the lowest position. Move the handle (O) forward and backward several times: this will free

the grate slots of the combustion ash.
CAUTION : The wood load must always be suitable for the actual thermal absorption requirements of
the plant. Large firewood loads in limited absorption conditions result in the unburnt wood remaining
in the fIrebox for long periods of time. This situation encourages the distillation of the wood resulting
in the formation of large quantities of gases and vapours that are only partially burned. The gases
condense in the central heating cooker and in the tubes and create tarry deposits.

5.4 GRATE POSITIONS IN THE 25, F25, 30 & F30

During the winter period the grate must remain in the lowest position in order to
guarantee the maximum heat exchange from the combustion to the boiler and
consequently to the water. There are 3 grate positions:

Lowered grate and only central heating
All the heat is transferred to the water to take full advantage of the wet surfaces.
Grate all the way up with flap (para. 5.5) on oven
All the heat is transferred to the cook top, the flame envelopes the oven completely.
Intermediate grate and flap positions
Combined by simply positioning the grate and flap in intermediate positions.
To lift the grate pull the grate handle down gently (O). When the grate is in the desired position
return the lever to its home position. The grate will be lifted to one of its 3 positions. If the

movement is hard, pull the handle back and forth several times in order to free the grate, before
taking it to the top position. It is easier to perform this operation when there is little material in the
firebox.
To lower the grate pull the handle (O) until the grate lifts slightly, lift the grate adjustment lever
release mechanism (N) and shift the handle (O) until the grate is lowered.

5.5 Grate position Country, Country F
Open the ash pan door (L) use the tool to rotate the nut (N) anti clockwise to raise and clockwise to

lower the grate.

The diagrams below shows the path of the heat showing the three grate positions and the how the
maximum amount of heat is transferred to the water in the boiler or the oven.

5.5 HOW TO USE THE OVEN IN CENTRAL HEATING COOKERS F25 - F30

By acting on the smoke deviator flap (diagram below) the central heating cooker can have 2
operating modes:

-Only central heating, in this mode the oven cannot be heated, only the left side of the cook top
plate is heated. In this operating mode the maximum heat output is transferred to the water. –

Heating and cooking, in this mode the oven can be heated, the entire cook top plate is heated.

Only central heating Cooking and central heating

5.6 THE FOLD-AWAY TOWEL RACK (ONLY FOR
25 - 30 - F25 - F30)

Central heating cookers models 25 - 30 - F25 ­F30 are fitted with 2 practical foldaway racks for
hanging your washing on to dry.
To extend them simply pull out as indicated in
the figure on the right .

6 CLEANING AND MAINTENANCE

6.1 GENERAL CLEANING

Before commencing any operation disconnect the central heating cooker from the electrical
power outlet. Your central heating cooker does not require any special maintenance; simply
adhere to the simple and basic, but regular controls and general cleaning. This will guarantee
regular operation and optimal output at all times. As for all machines that run on solid fuel, the
main enemy is undoubtedly the dirt generated by ash, condensation, poor fuels; consequently it
is important to clean the entire central heating cooker twice a year. The air inlets can be cleaned
with an ordinary vacuum cleaner.

However, we recommend having the flue outlet cleaned by a professional chimney
sweep.

Caution: The glass and all the glazed steel parts must be cleaned with water
and a gentle detergent when the oven has cooled.

6.2 ASH

The central heating cookers are fitted with 2 ash pans placed under the firebox base. To access the
pans you need to open the enamelled door of your central heating cooker completely. To collect the
ash simply shift the grate riddling handle (O) (see drawing below).
We recommend emptying the ash pans (G and P) on a regular basis to prevent them from filling up
completely. It is necessary to regularly clean under the oven by opening the plug K. and vacuuming
the ash deposits . To ensure that your central heating cooker performs efficiently it is advisable to
regularly clean the surfaces of the heat exchanger and of the smoke passages towards the chimney,
using the special equipment provided; to access them remove the cook top plates X as illustrated in
the drawing below. The tarry deposits reduce the exchange and consequently the output as well.

6.3 CLEANING THE HOT PLATES

Clean the hot plates with a normal gentle detergent. After cleaning (for the models with non-vitrified
hot plate), protect the plate by applying a film of oil to keep it clean and shiny. As an alternative to
the oil apply a thin film of protective chrome paste (readily available from your local hardware store).
Take care when applying the paste not to indelibly dirty the cast iron side cornices. If you detect any
rust use a lightly abrasive scouring pad to remove it and then proceed to apply the protective oil or
chrome paste.

6.4 HOW TO REPLACE THE OVEN LAMP (ONLY F 25 - F 30 )

To replace the oven lamp firstly open the oven door. Use a screwdriver or round-tip blunt knife to
lever gently between the glass (V) and the oven back until the glass V comes off its fastening
hooks. Then remove the lamp L and replace it with a new one type E 14 25 W 230-240 V 300°C.
The lamp is not covered by warranty as it is a consumable object.

6.5 RECOMMENDATIONS

-Every time you stoke the fire use the riddling tool to move the grate. Move the rod O indicated in
para. 6.2. The air passage through the firebox grate must always be unobstructed.

-Every 10 hours of operation at least or whenever necessary clean the ash pans G and P as
described in paragraph 6.2.

-Every 2 weeks or whenever necessary clean the internal surfaces of the heat exchanger, the oven
and the door K under the oven.

-Always ensure that the fuel fed into the firebox catches fire normally. Always ensure that this occurs
to prevent dangerous explosions in the firebox caused by the accumulation of unburnt gases. If these
explosions prove to be rather violent the manufacturer declines all responsibility for the mechanical
resistance of the glass and heater parts.

-Adhere strictly to the declared consumption: max. 8.5 Kg /hour for models 25 - F25
, max.10 Kg /hour for models 30 F30.

-Thoroughly clean the heater and flue at least twice each season

In the unlikely event that the appliance is not operating in freezing conditions the water must be
drained from the boiler to prevent frost damage

7 FLUE

CHIMNEYS basics

An efficient wood burning stove is one of the most effective ways to improve the energy efficiency &
reduce the CO2 emissions in a house. To achieve its optimal performance an efficient appliance
needs an efficient chimney system. The key to a well performing chimney is consistent insulation
along the entire length of the flue without cold spots.
Vacuum .05” WG average.
Solid fuel appliances need class 1 chimneys which are designed to deal with flue gas temperatures
above 260 deg C.
Class 1 chimneys can be of lined, masonary construction or of prefabricated insulated metal
construction.
The job of the chimney is two fold-:

1. To safely remove the products of combustion (SMOKE)

2. To generate suck (VACUUM) to provide the fire with an adequate supply of air.

3. DRAFT (suck or vacuum the chimney can develop) depends upon the following-:

 THE HEIGHT.
 THE POSITION OF THE TERMINAL RELATIVE TO OTHER, LOCAL, OBJECTS
 THE DIAMETER.
 THE TEMPERATURE OF THE GASSES IN IT. (lining and insulation may come into this)
 THE RESISTANCE OF THE INNER SURFACE OF THE CHIMNEY.
 THE AVAILABILITY OF ADEQUATE VENTILATION.
 THE HEIGHT ABOVE SEA LEVEL

4. Any bend in any part of the chimney or roughness on the internal chimney wall will slow down the
velocity of rising gasses and reduce the effectiveness of the chimney.

5. Any slight reduction in the flue gas temperature will reduce the chimney vacuum or pull, hence
when the stove is slowed down for all night burning, as the flue gas cools down the chimney vacuum
reduces and as the chimney vacuum drops, the stove may well go out. This problem is highlighted
even more during very cold weather when the chimney can cool down even faster.

Minimum draft of 18/20 PASCAL 0.18/0.20 mBAR
BEWARE, no one can guarantee that a chimney will work even after relining has been carried out.
Check out your chimney, look around your locality at other chimneys to see if there is a localised
problem of down draughting.

If you have bought a house and have no experience as to the performance of the chimney be very
careful, ask the previous owners and try to gather as much information as possible before you commit
yourself.
As a rough rule of thumb consider that if you have a 90 bend in the flue you will need an additional 1m
of height and for every metre of horizontal flue you will need an additional 2m of height.

LINING OF EXISTING CHIMNEY’S

Most old, leaking chimneys need lining and insulating with special materials designed to:-

1. Cure Leaks.

2. Reduce the build up of tar and soot on the walls of the flue.

3. Withstand the tremendous heat generated when tar and soot catch fire.

4. Generate a steady and controlled flue vacuum.
Old unlined chimneys are not suitable, if wood burning appliances are used on these chimneys the
following may happen:
Tar builds up on the brick faces of the internal chimney walls.
This build up can take from 12 months to 5 years, and as time passes the tar gets thicker and thicker,
in really bad cases the tar can work its way through the chimney walls into the plasterwork of
adjoining rooms staining the wallpaper or plaster and causing a pungent wood smoke smell which can
contaminate the affected rooms.
If a chimney in this state catches fire the results are severe causing bricks and mortar to crumble and
drop down the chimney, and tar to ouze through the affected walls.
Often, with a chimney fire of this nature it could well be necessary to remove the complete stack
taking out and replacing all the walls affected by the tar impingement.
Severe damage can also occur on some types of twin wall stainless steel chimneys, causing
distortion and leaks of flue gases.

A chimney cap is a device that is normally placed on top of a flue outlet for the purpose of facilitating
dispersion of the combustion products; it must satisfy the following requirements;

-have a useful exhaust section that is at least double the section of the flue outlet on which it is
inserted;

-have a shape that prevents the entry of snow or rain into the flue outlet;

-be built in such a way that venting of the combustion products is guaranteed regardless of wind
direction.

CHIMNEY HEIGHTS AND TERMINAL POSITIONS

Fig 1 is a rough guide about chimney heights and terminal positions.
Many manufacturers will call for a minimum flue height of 4.5 meters.
Document J of the building regulations provides details of the required statutory flue heights and
terminal positions, the British Standard for chimney height calculations is BS5854:1980. (1996)

It would be illegal to install any appliance in a residential dwelling without complying with
Document J or the manufacturers instructions.

In the schematic shown in fig1 chimney locations are graded on a scale of 1 to 4

4. being the optimum position.

3. being the next

2. being not very good and likely to cause problems

1. Being not capable of complying with current legislation.
Note that the fig 1 illustration is not accurate and should only be used as a general guide.
Before any instalation work is carried out, accurate compliance with Doc J of the Building Regs should
be ensured.

FIG 3 TWO STORY INSTALATIONS INTERNAL

7.3 CONNECTION TO THE CHIMNEY

The smoke outlet can be connected at the top of the hotplate or at the back of the central heating cooker
using the hardware provided as illustrated in the figure below. If you wish to connect the chimney to the
back of the heater then you need to close the top smoke outlet with the cover provided, remove the
perforated cover from the back and remove the fixed cover by undoing the screws. Next connect the cast
iron flue collar using the hardware provided. There must be no narrowing of the pipes that connect the
central heating cooker to the flue outlet. The joints must be completely airtight. The number of elbows
used must be kept to a minimum. Horizontal runs must be kept to a minimum and have a minimum slope
of 4%. Never use the same flue outlet for more than one appliance.

7.4 VENTILATION OF THE ROOMS

It is essential for the room in which the appliance is installed to be well-ventilated, also to guarantee
secondary air for combustion in the central heating cooker.
The natural air flow occurs directly through permanent apertures to the outside made in the walls of
the room, or by means of single or multiple ventilation ducting.
The ventilating air must come from outside and if possible, away from sources of pollution. Indirect
ventilation is also allowed by taking in air from rooms adjacent the one where the heater is installed

taking into account all the warnings and limitations specified below. •The apertures in the walls must

comply with the following requirements:

- -have an unobstructed section of at least 6cm² for each Kw of installed thermal power, with a

minimum limit of 100cm²;

- be made in such a way that the vent openings, both on the inside and outside of the wall, cannot be

obstructed;

- be protected with grills or similar systems in order not to reduce the section described above;- be

situated at floor-level.

-

The air flow can also be obtained from an adjacent room as long as:

- the adjacent room is equipped with direct ventilation in compliance with the points described above;

- in the room to be ventilated the installed appliances are only connected to one flue outlet;

- the adjacent room is not used as a bedroom or a common area of the building;

- the adjacent room is not a room with a fire hazard, such as storage sheds, garages, combustible

material store rooms, etc...;

- the adjacent room does not become a vacuum compared to the room to be ventilated due to an

opposite draught effect;

- the air flow from the adjacent room to the room to be ventilated is unobstructed through the

permanent apertures having an overall net secti]on of no less than that indicated above. These
apertures can be obtained by enlarging the space between the door and the floor.
