IMPORTANT
Since April 2002 only Registered Competent Engineers may install solid fuel red appliances without
involving the Local Authority Building Control Department. For more details contact HETAS. Euroheat
would suggest only Registered Competent Engineers such as HETAS approved engineers install
Euroheat appliances. If a competent approved engineer is not employed to install your appliance building
control must to contacted and a building control number is issued.
The installation of this appliance must comply with all local regulations, including those referring to
national and European Standards before it can be operated. The stove is not suitable for a shared flue.
Improper adjustment, alteration, maintenance or the fitting of replacement parts not recommended by
the manufacturer can cause injury or property damage. Do not operate the stove with faulty seals or damaged
glass.
Ensure all manuals are kept safely and are available for the user at all times.
Do not store or use petrol or other flammable vapours and liquids in the vicinity of this or any other
heating appliance. Do not use aerosol sprays near the stove when the stove is alight. Do not burn anything but
natural wood or approved coals on this appliance.
 Due to high operating temperatures of this appliance it should be located away from pedestrian traffic and
away from furniture and draperies. Do not store paper or wood near the appliance. Any mats and rugs put in
front of the stove should be fire proof and secured to prevent the possibility of tripping.
Advise all persons as to the stove’s high surface temperatures, including visitors. If it is possible for children
or infirm adults to come into contact with the stove, fit a suitable fire guard. Never let children “help” with the
stove in any way, even when the stove is cold. The glove supplied with the stove MUST always be worn when
opening the door handle and loading fuel onto the stove.
It is imperative that all air passageways into, out of, and within the appliance are kept clean. All permanent
ventilation into the room provided for the stove must remain clear and unobstructed at all times. Consideration
must be given to the need for extra ventilation if another heating source needing air is to be operated
simultaneously. If an extraction fan is proposed to be fitted to a connecting area of the house, after the stove
has been installed, professional advice should sought from a qualified engineer.
If a flue blockage or adverse weather conditions cause the insert to emit smoke, do not treat it as merely
a nuisance, this smoke will indicate that carbon monoxide is being emitted into the room. Properly installed,
operated and maintained this stove will not emit fumes into the dwelling. Occasional fumes from de-ashing
and re-fuelling may occur. However persistent fume emissions are potentially dangerous and must not be
tolerated. WARNING: If fume emissions persist the following immediate action should be taken:
Turn the insert to its minimum ring rate, open windows to ventilate the room and leave the premises and
allow the insert’s fuel to burn out before closing the windows. Do not re-light the insert without consulting
a qualied engineer. Your installing engineer should have tted a CO alarm in the same room as the
stove. If the alarm sounds unexpectedly, follow the instructions in the above paragraph.
 In the event of a chimney fire the stove should be turned to its minimum setting and the fire brigade
informed. Do not re-light the stove until the complete installation has been inspected by a qualified engineer.
 The appliance should be inspected regularly and the chimney cleaned at least annually. More frequent
cleaning may be required and the advice of a qualified chimney sweep should be sought. Always check for any
flue blockage before lighting the stove after a prolonged shut down.
This stove has been carefully designed and constructed to give clean burning with optimum efciency
and safety, but as with all stoves these standards will not be achieved unless the stove is installed and
maintained regularly by qualied engineers. It must also be operated strictly with the procedures given in
this manual.
If you are unsure about anything concerning your stove please seek professional advice.

Before Operating this Appliance
Always use the glove provided when tending the hot stove.
The paint used on the stove is a heat resistant paint capable of withstanding 650°C, but it needs to be heated
for several hours to allow it to cure and attain its full hardness. The lighting procedure should be followed and
the stove’s first fire limited to a small fire for one hour, after which its size can be gradually increased to allow
the stove to reach its operating temperature. As the temperature of the paint increases a blue hazy smoke will
be apparent as the solvents in the paint are driven out. These fumes may activate a smoke detector, if fitted,
and during this period the room must be ventilated by leaving the windows open and it should not be occupied
by people or pets. The time taken for the paint to be fully cured will be dependant upon the temperature but
you should allow at least six hours. If you re-paint or fit new parts to your stove, another period of curing will
be necessary but the curing time will be very much shorter.

Choice of Fuels
Wood
All wood will burn slightly differently, but the most important differences between woods is their moisture
content. Until the moisture has been driven off from the wood it will remain below its combustion
temperature. When the outer skin has dried and beginning to burn, much of this heat energy will be wasted
having to boil off the water remaining in the core of the wood. Copious amounts of water vapour, in all but
the most insulated flue, will condense, and mix with the products of combustion to form creosote and other
undesirable substances which will eat away the fabric of the flue, and eventually build up to block the flue. At
any time this build up of tar will be capable of causing a chimney fire.
The advice to burn only "dry" wood is sometimes confusing because the atmospheric moisture will prevent
wood ever becoming "dry". It is acceptable to burn wood with a moisture content of less than 20%, which can
be achieved by splitting the wood, stacking it so as to allow air to circulate within the stack and storing it under
cover for between 18 months and 30 months, depending on prevailing climatic conditions. The use of a wood
moisture content meter will confirm the amount of water remaining in the wood easily. The practice of drying
wood by the stove should be discouraged, firstly because it should be unnecessary, and secondly because
stored wood will invariably become the home to many varieties of insects, many of whom enjoy eating
wood. To introduce them into your house and encourage them with heat and time to make new homes in your
furniture and structural timbers is not recommended.
Peat
Peat burns very well, but it is bulky and its distinct aroma will pervade your home and everything in it, but
otherwise peat can be burned as wood.
Please note that HETAS Ltd Appliance Approval only covers the use of wood on this appliance. HETAS Ltd
Approval does not cover the use of other fuels either alone or mixed with wood nor does it cover instructions
for the use of other fuels.
The HWAM 20/80, HWAM 30/45 30/55 30/65 are not designed to burn coal,
coal products or any mineral fuel. The use of these fuels will invalidate the
manufacturers warranty.
Because the surface area exposed to the air will dictate the speed at which it burns, smaller pieces of wood
will give the maximum heat output from the stove but will quickly burn away. Larger logs will burn more
slowly and will take longer to deliver the equivalent heat. The burning times and firing rate will also be
controlled by the settings on the air supply; with the maximum air giving the highest heat output with the
shortest burning time. Caution should be exercised if the maximum burning time is required because putting
on large logs and shutting down the air supply is likely to promote very bad combustion unless the newly
loaded logs are burning enthusiastically. Whenever turning the stove down it should be done in stages to allow
all the releasing volatiles to burn; by shutting down the stove in stages the logs will be allowed time to cool
and release diminishing amounts of volatiles. It is important that the control for the air wash remains at its mid
position whatever the stove’s firing rate is set to. Depending upon the dryness of the wood and the type of
wood being burned it may be necessary to open the air wash further if deposits appear on the glass.
Stoves are not covered by a manufacturers warranty for any damaged caused by their being over fired.
General Tips about Fuelling

©EUROHEAT DISTRIBUTORS (H.B.S) LTD June 2011 E & OE Instructions Part number IN1212 Ed D

Choice Of Logs
Never burn wood that is not dry or wood that has been subject to a manufacturing process, such as chipboard,
as these contain resins of uncertain toxicity when burned. For the same reasons, wood that has been painted or
treated with a preservative should never be burned.
Natural wood is described as being either “hardwood” or “softwood”. Typically all broad leaf trees that lose their
leaves in the winter are called hardwoods, and the evergreen conifers are called softwoods. Whilst the wood
from the two groups have structural differences,the terms do not define the density or hardness of the wood.
Balsa, one of the softest and lightest of woods is classified as being a hardwood and Hemlock, a soft wood, is
extremely hard.
The less density wood has, the more its structure is made up of open spaces meaning it will season faster and
because of these voids it will burn faster because it will expose more surface area as it disintegrates. This makes
light woods suitable for kindling or a rapidly developing fire but unless you enjoy putting wood onto a fire every
few minutes it is unsuitable for burning over long periods. Although there is a difference in the speed at which
woods burn, equal weights of wood will give very similar amounts of heat.
Because logs are concentric tubes of cells they season faster if they are split, halving the tubes and allowing the
moisture to evaporate more easily. Similarly it also allows the volatile gases given off when the wood is heated
in a stove to be emitted along its full length rather than at the log’s ends. This helps the gases to be distributed
more evenly within the stove and improves not only the efficiency, and emission reduction of wood burning but
gives a more attractive fire.
Putting logs onto the fire, bark side down and laying them, well spaced, in random orientation, rather than
uniformly horizontally, will also help to increase the efficiency and attractiveness of the fire. To make this easier
the ideal log length will be the length the stove’s combustion chamber can accommodate in all directions, and
of proportionate cross-section, to allow you to load wood in a “higgledy-piggledy” manner.
DO NOT BURN
Anything but dry, natural wood. Wood that has been painted, treated or has hinges, nails or any plastic
attached will almost certainly emit toxic matter when burned. For similar reasons bonded wood products such
as chipboard, plywood or fibre board must never be burned.
DO NOT BURN
Household waste. Many seemingly innocuous items like box packaging have been coated with glazes
which will produce toxic matter when burned. One old video tape put on the fire will cause more
pollution in a few minutes than a life time of wood burning. Not only will a fire burning rubbish
pollute, the stove is not designed to contain such an assortment of sizes and weights and a flaming
box falling from the stove when the door is opened will present an unacceptable fire hazard.
WARNING NOTE
Properly installed,operated and maintained a stove will not emit fumes into the dwelling. Occasional fumes
from de-ashing and re-fuelling may occur. However, persistant fume emission is potentially dangerous and
must not be tolerated. If fume emission does persist,then the following immediate action should be taken:-
(a) Open doors and windows to veentilate the room and then leave the premises.
(b) Let the fire go out
(c) Check for the flue or chimneyblockage and clean if required.
(d) Do not attempt to relight the fire until the cause of fume emission has been identified and corrected, if
necessary seek expert advice.
The most common cause of fume emission is flueway or chimney blockage. For your own safety these must be
kept clean at all times
CO ALARM
Your installer should have fitted a CO alarm in the same room as the appliance. If the alarm sounds
unexpectedly follow the instructions given under “Warning Note” above.

The Automatic Combustion System
A bimetallic coil responds to the heat in the secondary combustion chamber by expanding and contracting,
causing it to rotate its central spindle, the spindle is attached to an arm which raises or lowers, dependant upon
the heat of the flue gasses, a plate or plates which open or close the primary air (lower inlet) and the secondary
air (upper inlet).
The Three Phases of a Fire:
1) The lighting phase, where there must be an air supply at the top and bottom of the fire (secondary and primary
air, respectively).
2) The combustion phase. At the ideal temperature of between 1000-1200° Celsius the coil will have closed the
primary air supply and the fire will receive all its air supply from the secondary inlet.
3) The burning-out phase. As the temperature falls, the air supply above the fire is gradually reduced, and the
primary air is increased, to supply air to the embers.
Grate Cover Plate
The HWAM 20/80 stove is supplied with a loose cover plate for the riddling grate. This 3mm thick steel plate must
be positioned to rest centrally on the top of the riddling grate to prevent burning embers from falling into the ash
pan. When fitted correctly the plate allows an 8 mm peripheral slot above the grate, ensuring that the primary
air supply is distributed evenly across the base of the combustion chamber.
When the ue temperature is low the cold bimetallic coil positions the shutter to maximise the
air supply below the grate. As the ue increases in temperature the coil heats and begins to
unwind, causing the air being sent under the grate to be reduced and the air supplied above
the grate to be increased.

First Lighting of the Stove
When you light the stove for the first few times it should be with small fires increasing in size, as all the materials
must be given time to adapt to the effects of heat. The paint on the body of the stove will be fully hardened after
the stove has been cured, however the door and the ash pan should be opened very carefully before curing as
there will otherwise be a risk that the gaskets will stick to the paint. If the chimney has been used previously
and was not newly lined when the stove was installed it must be swept before lighting the stove for the first
time. The chimney will need to be swept again after about one hundred hours of stove operation to ensure no
old debris remaining have loosened or have fallen.
Curing
The paint may initially give off unpleasant fumes and an odour, so make sure that the room is well ventilated.
The paint will be soft, so care must be taken with the stove for the first 6-8 firings. Curing the paint is necessary
on all stoves and is not a fault.
We recommend following lighting procedure for lighting
the stove for the rst time.
Make sure the air controls are set to maximum and the ash-pit is closed. Place
two lightly crumpled sheets of tabloid sized newspaper in the stove, then
lean some small, extremely dry kindling with a diameter of between 3–5cm
against the paper to give a conical formation, leaving space between each
piece. Leave the door of the stove slightly open, keeping the door slightly
ajar until the kindling is burning brightly, then close it securely.
Do not leave the stove unattended with the door open.
When the original kindling is burning well, add a similar amount of kindling.
Always use the glove supplied with the stove when loading with fuel or
operating any of the controls or handles.
Adjust the burning rate control to mid/low setting.
Using small logs keep the fire burning low for two hours then gradually build
up the fire.

General Lighting and Operation
Lightly crumple two tabloid sized pieces of newspaper and
lay them in the middle of the grate.
Resist the temptation to use more paper than this, or to crumple
it too tightly; doing either will prevent the rapid development
of flames and will cause smoke to be produced.
The kindling wood should be placed over the paper so as to
rest against each other in a conical formation, leaving space
between each piece.
Set both the air wash control (20/80 only) and the burn rate
control to their maximum setting.
Light the paper using a long match or spill and leave the stove
door slightly ajar.
The lightly crumpled paper will begin burning rapidly and the
space between the kindling will allow the long bright flames
to pass between and over the wood, raising it to its ignition
temperature.
Keep the door slightly ajar until the kindling is burning brightly.
Then shut the door. Never leave the stove unattended with
the stove door open.
As the cone of kindling burns it will collapse and the inner
ends of the wood will begin to char and glow.
Wait until the kindling is burning at its maximum rate before
moving onto the next stage.

©EUROHEAT DISTRIBUTORS (H.B.S) LTD June 2011 E & OE Instructions Part number IN1212 Ed D
12
Wearing the stove glove place a few logs larger than kindling
wood over, but not smothering the kindling.
When the previous loading of wood is burning brightly add two
larger split logs to bridge the fire. Always avoid putting wood
directly onto wood burning with flame, try and leave air space
under the wood for the flame to form, because the new, cold
log will tend to cool the fire.
Reduce the burn rate control setting when the fire is established to the desired heat output and set the air wash
control (20/80 only) to the mid setting.
Putting new logs bark side down, will give you both maximum
efficiency and best visual effect as it begins to burn.
At the rear of the combustion chamber you will observe that
there are a series of holes or slots, these are there to allow air
into the combustion chamber and should NOT be covered at any
time.

General Maintenance of the Stove
Ash Removal 20/80
The ash pan must NOT be removed and emptied when the stove is operating. Removal of the ash pan when the
stove is lit will allow unregulated air to enter the stove which can damage the automatic combustion control
system.
Do not allow ash to block the combustion air slots/holes at the rear of the combustion chamber. We recommend
that these slots/holes are cleared regularly.
The embers within the ashes may remain alight for up to 24 hours after the stove has gone out, so they must be
disposed of in a non-combustible container.
Ash Removal i30/45 i30/55 and i30/65
We recommend the use of an Ash Vac for ash removal of the above appliances, However wood burns quite
happily on a bed of ash, so the removal of it may be very infrequent. If an ash vac is not available a small shovel
and bucket can be used. Be very carefull not to damage the mica baffle and bricks.
Cleaning the Glass
Before attempting to clean your stove’s glass the stove must be extinguished and allowed to cool, it would be
potentially unsafe to, and would risk the glass shattering if attempts are made to clean it while hot.
The glass in your stove is specially formulated to withstand the very high temperatures and proprietary glass
cleaners developed for ordinary glass are not recommended as their compositions may contain chemicals that
will weaken or etch into the glass.
Newspaper moistened with water to which a little vinegar has been added will normally remove most staining,
but for really stubborn marks, gentle polishing with fine steel wool lubricated with a few drops of dish washing
detergent will need to be employed. Great care must be taken not to clean the glass too vigorously as particles
of grit may have adhered with the stain and these could cause scratching if dragged across the glass. However
well the stove burns it will eventually become necessary to clean the glass, but if cleaning becomes necessary
too often we advise you to review your operating procedures to determine whether cleaner and more efficient
combustion can be achieved.
Check the condition of the seals around the glass regularly for signs of leakage; replace only using the manufacturer’s
sealing gaskets.

To clean the glass on the i30/45, i30/55 and the
i30/65 open the lift up door half way and hold it
there.
At the same time pull the arms (1) outwards off and
over screw (2) and the glass will come forward.
You can then lower the glass door down and rest
the bottom edge off the glass against the body of
the stove.

The Stove Body
Any maintenance of the stove should only be carried out when it is cold. Daily maintenance is limited to vacuum
cleaning the stove externally, using the soft brush attachment. You can also dust the stove using a dry, soft cloth
or brush, but only when the stove is cold.
Maintaining Painted Surfaces
No paint will tolerate the temperatures within the stove’s combustion chamber and it is normal for the paint
within the combustion chamber to loosen and flake. If the stove’s exterior paintwork becomes damaged it can
be simply repaired by sanding the area with a fine wet and dry paper and the using a Hwam approved paint to
respray the area.
Never use or store any aerosol near the stove when it is operating or warm. Aerosols can give off an explosive
vapour which may be drawn into the stove and explode.
Spray Paint
Order product number HW99-0043BL for black surfaces, and HW99-0043GRY for grey surfaces.
Professional Maintenance
The stove and the installation should be thoroughly inspected and serviced by a suitably qualified heating engineer
annually. The combustion chamber should be cleared of ashes and soot. Door and fittings should be lubricated
using a copper-based grease.

Operational Problems
Blackened Glass
The wood is too damp. Only use wood stored for at least 12 months under cover and with a moisture level not
exceeding 25%.
Insufficient intake of secondary air for the glass air wash.
Smoke in the Room when Opening Door
Open the door slowly, to allow the air flow and pressure changes within the stove to adjust.
Insufficient chimney draught. See the section on the chimney installation instructions or contact a chimney
sweep. Soot door leaking or dislodged. Replace or refit.
Never open the door when there are more than small flames from the wood.
If smoke appears when the stove door is closed, turn the stove to its minimum settings, open the room windows
until the fire is extinguished and ascertain the cause of the smoke before relighting the stove
Uncontrollable Combustion
Faulty seal in door or ash pan. Fit new seal.
If there is an excessive chimney draft, it may be necessary to fit a draught stabilizer or a stabilizing cowl (See
installation instructions).
If the steel plates in the combustion chamber delaminate to develop scales or become deformed, this is due to
excessive heat caused by over firing the stove. This can be caused by excessive chimney draught, or incorrect
operation of the stove. If over firing is evident contact your local retailer who can advise you on the cause and
most suitable remedy.
Noise
As the metalwork of the stove expands and contracts with the rise and fall of temperature those parts expanding
or contracting faster than an adjacent part emit a ticking noise as they fret against each other. Larger parts getting
to high temperatures may make a louder noise as their expansion and contraction allows them to spring into a
minutely different profile. None of these causes of noise have any effect on the operation or longevity of the stove.
A whistling noise is evidence of a leaking stove or flue and should be investigated as soon as practicable.
Cracked Glass
The glass in the stove door is a special ceramic glass capable of withstanding extremely high temperatures,
but it is particularly sensitive to knocks and blows at high temperatures and sudden localised differences in
temperature.
If the door is closed aggressively or is subjected to knocks and blows in other ways, there is a high risk of the glass
cracking, typically at the corners where it is secured to the door. A flame impinging against the glass will cause
the impingement area to overheat and initiate a crack. Do not operate the stove with a faulty glass.
White or Opaque Glass
If soot or tar is allowed to be deposited form on the glass it will eventually clear when the stove reaches a
high temperature but a white haze will remain on the glass. This can be wiped off when the stove is cold but
the stove’s operation should be reviewed to avoid staining. If the glass becomes too hot it will firstly begin to
craze then revert to its original opaque white appearance, irrevocably. This happens when flames are allowed to
impinge against the glass producing typically coin sized round white areas. Replacement of the glass will become
necessary if this is allowed to happen. Do not operate the stove with a faulty glass.
Burning anything but natural wood will not only harm the environment, but the chemicals formed when resins
and other substances are heated may cause the glass to craze and be weakened, necessitating its replacement.

©EUROHEAT DISTRIBUTORS (H.B.S) LTD June 2011 E & OE Instructions Part number IN1212 Ed D
16
Other Maintenance
The stove must be cleaned of ash and any tarring as often as your use of the stove dictates. All deposits on the
stove interior will insulate the stove body from the fire and will reduce the stove’s efficiency. Flue ways which
become choked will not only reduce the stoves performance but can become a serious health risk if the flue is
not taking away all the gaseous products of combustion. It is important that all the stove seals are replaced when
any signs of wear are apparent or they become degraded and that only parts approved by Hwam/Euroheat are
fitted, these may be obtained from your local retailer or directly from Euroheat.
Summer Shut Down
At the end of each heating season the entire installation should be thoroughly cleaned and examined for soundness,
this should include having the flue examined by a registered sweep. The stove interior should be thoroughly
cleaned of all ash, taking due precautions because embers my still be alight for over twenty four hours after the
stove has been let out. All interior metalwork should be protected by a proprietary surface moisture repellant.
The controls may be set to their open position to allow air to pass through the stove and flue to reduce the risk of
condensation causing damage. All operating mechanisms should be lubricated with a high temperature grease.
Always check the stove and flue for any blockage before lighting the stove after a prolonged shut down.
Faulty Operation
If poor fuel and haphazard operating procedures can be ruled out, excess or poor flue draught are the most
likely cause of a badly performing stove. A flue draught manometer will identify these quickly, but the actual
causes of things such as an unreliable flue draught may take some considerable time, even by an experienced
engineer to identify. However, if the stove has never performed correctly, call back the installation engineer. If its
performance has deteriorated, examine the stove and the flue for soot and debris accumulation; ensure the door
and glass seals are sound before contacting the engineer.
The Flue
Because so little of the fires heat is lost to the flue the installation guides recommend that your chimney is lined
and insulated. A badly insulated or an oversized flue may cause problems if humid flue gasses cool and form an
acidic condensate on the surface of the flue. This may manifest itself as blackened water appearing beneath the
flue pipe or discolouration on the chimney breast. Even if your flue is correctly lined it is advisable to run your
stove at a high setting to thoroughly warm the flue periodically and ensure it is swept regularly by a qualified
sweep who will be able to advise you of any potential problems before they become hazardous. The chimney
should be swept after six months operation by a qualified sweep at least annually, even if the stove is only used
occasionally and the sweep will be able to advise you if more frequent sweeping is necessary. Before sweeping,
the air controls must be turned to the minimum setting to prevent soot and ash from entering the automatic
system.

The Combustion Chamber Lining has Cracked or Broken Panels
The fireproof lining panels in the combustion chamber are made of vermiculite, which is a natural material that
can withstand very high temperatures, that reflect the heat within the combustion chamber to maintain the
optimum temperature within the combustion chamber while protecting the metalwork. However, the material
will not withstand mechanical abuse and will be damaged by heavy blows from logs being badly loaded. Cracks in
otherwise correctly positioned panels will not have an adverse effect of the stove or its ability to burn correctly,
but incomplete panels or panels worn to less than 50% of their original thickness must be replaced.
Service
The installation and stove should be inspected and serviced annually but even if the stove is only used
periodically it should have a thorough service check at least every other year. This service check must include
the following:
• Thoroughly cleaning of the stove and removal of all ash.
• Checking of the door lift and greasing the opening mechanism with heat resistant grease.
• Checking of the spring for the chain pull and replacing if necessary.
• Checking of manual air controls and automatic air control system.
• Checking of gaskets and replace if necessary.
(The door gasket should always be replaced annually)
• Checking of the combustion chamber panels and replacing if necessary.
• Checking of the bottom/shaking grate.
All service checks must be performed by an authorized fitter. Use only original manufacturer spare parts.
The flue must be cleaned and inspected to verify its safety by a registered sweep.
Chimney Cleaning
To facilitate cleaning through the stove to the flue the vermiculite and the steel baffle will need to be removed
To remove the vermiculite baffle plate. Push the plate backwards, lift it upwards and slightly sideways, tilt
down one side and the plate should be free and can be removed from the combustion chamber. To remove the
iron baffle plate. Straighten the transport lock. Lift the plate off the hooks after which it may be removed from
the combustion chamber. See the installation document for more information.

IMPORTANT.
The installation of this appliance must comply with all local regulations, including those referring to
national and European Standards before it can be operated. The stove is not suitable for a shared ue.
However, for England and Wales, only, the coming into force on 1st April 2002 of SI 2002 No 440 exempts
the householder from this legal requirement for the installation of solid fuel red appliance whose rated heat
output is 50kW or less in a building having no more than 3 storeys (excluding any basement) if a Competent
Engineer is employed who is registered under the Registration Scheme for Companies and Engineers
involved in the Installation and Maintenance of Domestic Solid Fuel Fired Equipment operated by HETAS
Ltd. These registered Competent Engineers may also carry out associated building work necessary to
ensure that the installed appliance complies with Building Regulations without involving the Local Authority
Building Control Department. The installing engineer should refer to BS 8303: Code of practice for installation
of domestic heating and cooking appliances burning solid mineral fuels.
Improper adjustment, alteration, maintenance or the tting of replacement parts not recommended
by the manufacturer can cause injury or property damage. Do not operate the stove with faulty seals or
damaged glass.
 Due to the high operating temperatures of this appliance it should be located away from pedestrian
trafc and away from furniture and draperies. Do not store paper or wood near the appliance. Any mats and
rugs put in front of the stove should be re proof and secured to prevent the possibility of tripping.
Advise all persons as to the stove’s high surface temperatures. If it is possible for children or inrm
adults to come into contact with the stove, t a suitable re guard.
It is imperative that all air passageways into, out of, and within the appliance are kept clean. All
permanent ventilation into the room provided for the stove must remain clear and unobstructed at all times.
Consideration must be given to the need for extra ventilation if another heating source needing air is to be
operated simultaneously. If an extraction fan is proposed to be tted to a connecting area of the house, after
the stove has been installed, professional advice should be sought from a qualied engineer.
The user should be advised that the appliance should be inspected regularly and the chimney cleaned
at least annually.
More frequent cleaning may be required and the advice of a qualied chimney sweep should be sought.
 Our range of stoves is capable of operating with outstanding efciency if the ue system is correct.
Because so little heat is wasted to the ue it is possible that moisture within the products of combustion
will condense if the heat losses within the ue way are too great and allow the ue gases to cool. For this
reason we recommend that the stove is tted with a suitable ue liner, the same diameter as the ue spigot,
to prevent the possibility of acidic damage to the fabric of the chimney and damage to the stove which will
reduce the longevity of the stove. The ue pipe and chimney ue diameter must at no point be less than
the diameter of the stove ue outlet. The installing engineer should refer to BS EN 15287-1:2007 design,
installation and commissioning of chimneys.
 When correctly installed, the stove is designed to produce heat, safely. It cannot do so if the installation
is less than absolutely stable, constructed of materials suitable for such an installation and consideration
has not been given to the possibility of people with less than ideal common sense operating it.
 Have the existing chimney swept by a chimney sweep. Although you will be lining the chimney, any
deposits left in the chimney will cause problems and may become a re hazard.
 Your attention is drawn to the precautions and responsibilities under the Health and Safety at Work Acts,
and whatever new legislation being introduced during the life of this document. Especially to the possibility
of disturbing asbestos when disturbing structures in older properties. Also the caustic nature of re cement.
The personal risk of injury when moving heavy items with possible sharp edges.
