IMPORTANT

Since April 2002 only Registered Competent Engineers may install solid fuel fired 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 be 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 firing 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 qualified
engineer. Your installing engineer should have fitted 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 efficiency and safety,
but as with all stoves these standards will not be achieved unless the stove is installed and maintained regularly
by qualified 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

Watch, on the Euroheat web site: www.euroheat.co.uk/movies, the film of how to operate the stove
which can be found in the “Movie Library.”

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.

Multifuel and Wood Stoves

Gas and oil are consistent fuels and stoves can be designed to obtain the maximum heat from them with the
user having to do no more than choose a heat setting. Solid fuels are almost infinitely variable and however well
a stove has been designed, its performance will ultimately depend on the way the user operates it. Whilst we
have endeavoured to make the stove as simple to operate as possible, understanding just a little about the fuels
and the way your stove was designed to burn them will be rewarded by your being able to achieve the best from
your stove with the least effort.

As a fuel, wood is visually exciting, environmentally friendly, and a renewable source of energy but it is one of
the most complex fuels to burn. Wood contains two sorts of components which burn. The fixed carbons which
burn as the glowing embers, and the compounds that vaporize when heated to burn as volatile gasses, giving
the endlessly changing flame patterns. The fixed carbon, which is charcoal, is a virtually trouble free fuel and
needs little assistance to burn cleanly, but it would be difficult to describe it as visually entertaining.

When set to its wood burning position, your stove heats the incoming air to ensure it has the minimum cooling
effect on any volatiles. The air is supplied as slowly as possible so as not to blow out any established flames
and it comes in across the full width of the stove ensuring that all parts of the stove receive an equal air supply.
Because the air enters slowly over a curved blade the air is directed towards the burning volatiles rather than the
bed of the fire, this allows the tar laden volatile components to use the incoming air as a priority. By placing a
log or two towards the front of the fire whenever the flames from previous logs die down, a bed of charcoal will
build up. This will be virtually pure carbon and capable of burning for incredibly long periods without causing any
tar deposits on the stove’s glass even when the air supply is reduced to minimal setting.

Always put logs on to the fire before flames from previous logs have extinguished, this will ensure that when the
new logs begin releasing gasses it will ignite. Unburned gasses will cause smoke and tar deposits and wastes
potential heat. Putting on too much wood at one time will both restrict the air supply and cool the combustion
chamber making it more difficult for the gasses to burn cleanly.

Never put on fresh wood whilst operating the stove with a minuscule air supply as a technique for operating
for long periods without attention, it will cause both chilling and air restriction. Properly controlling the rate at
which wood burns is not simply a matter of restricting the air supply, nor running the stove with a very small
fire, it is maintaining the temperature and ignition flames in the stove whilst balancing the release of gasses to
match the chosen air supply.

No two woods have the same burning characteristics but all wood contains water. It is difficult to quantify the
amount of water any log might hold whilst its exterior feels dry but it would not be unreasonable to estimate a
mug full from a good sized, poorly seasoned log, Imagine pouring that onto your fire every time you introduce
a new log and you will realize its obvious effect of cooling the fire. What is not so obvious is that the moisture
mixing with the vaporized gasses is cooling them, possibly below their ignition temperature. So the water within
a wet log cooled the stove, it has prevented much of the potential heat from the log being realized and the
unburned combustible products will be deposited as tars within the stove and flue. Advice on how to dry wood
can be found on the “User Guide” supplied with the stove.

Smokleless coal suitable for stoves has only a very small proportion of components that vaporise and a far higher
fixed carbon content and when the stove is set to its coal burning position air is supplied through the grate to the
underside of the fire bed to supply the carbon directly. There will be sufficient spare air travelling through the fire
bed to reach the limited gasses being released and this air will have been heated as it passed the burning coals.

Because smokeless coals suitable for stoves have so little vaporizing content they are virtually trouble free fuels
to use, but if you are using one of the manufactured smokeless coals take care to ensure the ash pan is checked
regularly because some of them have a very high ash content; this is especially important if you change “brands”
because the ash contents can vary dramatically.
Always riddle the grate before putting on loadings of smokeless coal to give the initial release of gasses sufficient
air with which to burn; failure to do so may allow the stove and flue to fill with gasses ready to ignite.

A stove is very much safer than an open fire, but if you have children or infirm people in the house please ensure
it is suitably guarded, and consideration should also be given to accidental contact with the stove if you are
entertaining with a busy house full of guests. If you have a remotely operated stove please ensure you keep the
remote operating handset well away from the stove, children and dogs.

Choice of Fuels

Use of fuels in smoke exempt areas. (See data table for exempt models)

If you are operating this stove within a smoke exempt area it is approved for use for the following fuels only.
Seasoned dry wood. With a moisture content of 20% or less. Smokeless coal approved for use in smoke exempt
areas. Other fuels such as house coal, anthracite, briquettes, waste wood, peat, wood over 20% moisture must
not be used unless approved for use in smoke exempt areas.

Please note that HETAS Ltd Appliances Approval only covers the use of wood logs on this appliance. HETAS Ltd
Approval does not cover the use of other fuels either alone or mixed with the wood logs, nor does it cover
instructions for the use of other 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.

Smokeless Coal

Various manufactured smokeless coals are available giving differing burning characteristics and the manufacturers
or your coal merchant will advise you as to their suitability for stoves. Due to the variable quality of anthracite we
do not recommend its use. The difficulties and dangers associated with burning ordinary bituminous coal

(house coal) with its relatively high volatile content make it totally unsuitable and potentially dangerous
for burning in any stove.

Lignite (also known as solid mineral fuel)

Lignite is obtainable in briquette form and is best described as young coal. It behaves very much like coal and
should be burned as smokeless manufactured coal.

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.

DO NOT BURN petroleum based fuels such as petro-coke, they may seriously damage your stove. The manufacturers
of other blended coal products, containing a proportion of petro-coke, should be approached to confirm the
suitability of the product for use within an enclosed appliance that does not have a chrome steel grate.

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 “soft wood”. Typically all broad leaf trees that lose their
leaves in the winter are called hard woods, and the evergreen conifers are called soft woods. 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 gasses 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 gasses 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.

LOG SIZES

Stove model Ideal Log Length Maximum Log Length

Size 13 8 inches, 200mm 12 inches, 300mm

Size 23 8 inches, 200mm 13 inches, 330mm

Size 33 9 inches, 220mm 15 inches, 367mm

Size 43 10 inches, 250mm 17 inches, 432mm

All logs should be split and ideally, quartered.

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 a chipboard,
ply wood 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.

The Plexus Air Control

Your stove will have one of these control panels, allowing you to adjust both the volume, by rotating the round
knob, and the direction from which air enters the stove, by moving the lever vertically up or down.

Air Direction Lever

When the direction lever is in its uppermost position the air enters the stove above the fire, and when set to its
lower position air enters the stove from beneath the grate. Positioning the lever at its mid position will supply
air both over and under the fire and this position is used when lighting a fire or burning manufactured smokeless
coals. It should be set to its bottom position when burning natural smokeless coal such as anthracite and at its
top position when burning wood.

Air Volume Control

The air volume should be set to maximum, 9 O’clock, only when lighting and the flue is cold. Settings giving
normal operating temperatures will usually be between 12 O’clock and 3 O’clock, with slow burning being
achieved when the control is set between 3 O’clock and 6 O’clock.
Do not expect the stove’s performance to match any setting repeatedly because it will be affected by so many
other factors such as fuel quality and weather conditions.
