Your HARMONY heating appliance has been carefully designed and constructed to give optimum
efficiency, but as with all stoves, it needs to be operated correctly if its full potential is to be realized.
We hope these notes will help you obtain the satisfaction you expect from your stove.

Operating the Stove for the First Time
It is important that two or three small fires are burned in the appliance before the appliance is
operated at its maximum. This will allow the cast iron construction to settle, breaking away any
surplus sealing compound and, if cast black finish, the paint to cure. While the paint cures it will emit
a pungent smell and a window should be left open until the curing is completed.
Lighting a Wood Fire
Open the air wash vent and set the thermostatic damper to "Minimum". Place some crumpled
paper onto the grate, and on this place some tightly rolled paper followed by a few small pieces of
wood. (Firelighters are not recommended for wood fires as they are designed to give a small, long
burning flame for coal lighting). Light the loosely crumpled paper and close the stove door.
The air entering the stove through the air wash vent will keep
any smoke away from the glass and supply sufficient air to cause
the paper to burn quickly. When the wood kindling is burning well,
load larger pieces of wood onto the fire. Control the burning rate
of the fire with the air wash vent setting. It may be necessary
to leave the front door of the stove ajar slightly until the kindling
wood is burning if the flue has a very poor draught when cold.
Extreme caution must be exercised to ensure nothing falls from
the stove whenever the front door is opened, and the stove must
never be left unattended with any of its doors open.
Burning with Wood
Air supplied to a wood fire above the fire bed mixes with and allows the combustion of the potential
soot producing volatile gases released from the wood. Any "spare" air available reaches the wood
to generate more heat within the wood, which in turn generates more gases. For this reason, the
stove's air wash vent, should be used to control the tempo of the fire as it not only supplies this "top
air", but it does so by passing over the door glass, forming a barrier of clean air between the glass
and the fire. The thermostatic air damper must remain closed when burning wood to prevent air
entering through the fire bed itself, which may cause the wood to generate more gases than the air
available within the combustion chamber will allow to be burned completely.

Extended Wood Burning
Simply loading a huge quantity of wood into an idling stove and restricting the air supply is not the
way to achieve satisfactory extended burning. However dry the wood may seem it will contain some
moisture. This moisture will keep the wood and volatile gases below their ignition temperature until
it has been converted to water vapour and driven out of the stove. The volatile matter, instead of
burning to produce heat, will mix with water vapour and rapidly coat the stove with deposits and with
little protection from a very small air wash flow, the glass will become obscured.
Raising the firing rate of the stove for some time before loading, will allow the residual heat to drive
off the moisture from the wood as rapidly as possible and help maintain the temperature within the
stove to ensure the initial volatile gases are kept above their ignition temperature to burn cleanly.
When the fire is well established the air wash should be progressively closed to the position which
will hold the stoves burning rate at its minimum. This position will vary with each installation as it is
determined by the flue draught and wood being burned; experience is the only guide. Do not load
un-split, round section logs as these will invariably roll onto the glass to cause staining, as will the
emission of moisture laden gases from logs when loaded so that the end grain faces, and is near to
the glass.
Fuelling the Stove with Wood
Loading the stove through the top loading door, and having the air wash vent closed whilst refuelling
will minimize any fumes escaping from the stove. If the fire has become very low it is advisable to
rake the embers towards the front of the stove and allow the fire to glow brightly for a few minutes
by opening the air wash fully.
Always rake a portion of the embers towards the front of the stove and place the wood towards the
back of the stove as this will minimize the possibility of smoke reaching the glass and of the wood
itself falling against the glass. Obviously wet wood should never be burned, but all wood will contain
some water, and after loading the stove the door should be closed and the air wash opened
until the moisture has been driven from the wood and the newly introduced wood is burning well.
Unless this is done the slowly circulating smoke and water vapour will cause sooty deposits within
the stove. Refuelling "little and often" will give the most visually satisfying stove, and until you gain
the experience in operating your stove it will be the simplest method of operation. Successfully
burning large charges of fuel is only possible when you understand the operation of your stove, the
performance of your flue, and the characteristics of the wood you are burning.
Ash Removal with Wood
Because it is not necessary, nor desirable, to supply air to a wood fire through the grate, it is only
when the amount of ash above the grate becomes unsightly that riddling the grate becomes
desirable. Ash will, however, drop into the ash pan naturally and the ash pan should be checked
periodically, and certainly before riddling, to prevent ash overflowing from the ash pan into the stove.
Carrying an overflowing ash pan through the house is both messy and a fire hazard. The ash pan
withdrawing tool is not designed as a handle with which to carry the ash pan; use both hands and
wear heat proof gloves.
Leaving the ash door of the stove open allows an uncontrolled air supply into the stove and may
allow the stove to burn at a rate beyond its design capability. When removing ash replace the ash
pan as soon as possible. Make it a practice never to leave this door open as no stove will survive
being made to glow cherry red.

Lighting a Coal Fire
Lighting a Coal Fire with Wood and Paper
If lighting the stove with paper and wood, open the air wash vent
and set the thermostatic damper to "Minimum". Place some lightly
crumpled paper on the grate and upon this place some tightly rolled
paper, followed by kindling wood and a few small pieces of coal. Light
the loosely crumpled paper, close the front door and allow the wood to
be burning thoroughly before placing more coal on the fire. At this point
the thermostatic damper should be set to its "Maximum" position
and the air wash vent repositioned so that it provides the minimum
air necessary to keep any smoke from reaching the glass. When the
coal is burning without smoke the air wash should be closed and the
fire controlled with the thermostatic damper only.
Lighting a Coal Fire with Firelighters
If lighting the fire with propriety firelighters, open the air wash vent very slightly and the thermostatic
damper set to "Mid" position. A bed of small coals should be placed on the grate, two firelighters placed
centrally on this bed some 20mm apart and upon which further small coals should be placed. Care
should be taken not to put too much coal on the firelighters as this will prevent
them burning freely as a small flame below
the coals. Light the firelighters and close
the stove door. Monitor the flame from the
firelighters to ensure they are burning quietly
and not subjected to excessive draught.
When the coals are seen to be burning, more
coal can be placed on the fire. Close the
air wash vent and the fire controlled by the
thermostatic damper.

Operation with Coal
When burning coal, all the air entering the stove must be supplied through the grate and be controlled
by the thermostatic damper. Allowing air into the stove through the air wash vent will possibly cause
the fire to burn out of control at a higher rate than the stove was designed for. Because of the intense
heat generated within the coal itself the grate will, without being cooled by the incoming air, become
overheated and damaged. The thermostatic damper is designed to regulate the fire to burn at a
constant and controlled output whatever the fuel load, and because it operates gradually the grate is
always supplied with sufficient cooling air for the fire size. The thermostatic damper purposely reacts
to temperature changes slowly, corresponding to the way in which a coal fire will naturally respond to a
changing air supply. Overriding this by setting the control to the extremes in an attempt to build up the
firing rate rapidly, then shutting it down suddenly, is of no benefit and may cause damage to the stove.
Sudden loss of air through the grate may allow the grate to overheat, it will cause clinker to be formed
and will for some time fill the stove with gases which could ignite suddenly if an air supply is reintroduced.
All adjustments to the thermostatic damper should be done as gradually as possible.
Burning bituminous coals or the practice of mixing coal and wood is not recommended
because it will require constant adjustment of the stove's air supplies to prevent the
glass sooting or the coal to be burned satisfactorily without risk of damage to the grate.
Take the time to try all the fuels your coal merchant recommends for your stove, to find
the product which will give you the burning characteristics you want. Poor quality coal or
mixing fuels is both labour intensive and a false economy.
Fuelling the Stove with Coal
Before refuelling the stove, the grate should be riddled and the stove allowed a few
minutes burning to ensure ash has not been restricting air into the fire. Failure to do
this may result in the occurrence of newly introduced fuel being heated sufficiently
to give off some volatile gases which are unable to burn because of air deficiency.
Riddling the stove at this point will introduce an increased air supply which, if the
volatile gases are hot enough, will cause a small, safe, but disconcerting explosion as these gases
suddenly ignite. For similar reasons, whilst it is generally advised that all air supplies to a stove
should be closed to increase the flow of air in through the open door when refuelling, when burning
coal care should be taken if the stove was burning brightly to open the door slightly before shutting
the thermostatic damper. As with wood burning, reloading on a "little but often" cycle will give
the best visual effect, but unlike wood no special techniques need be applied when loading large
amounts for extended burning cycles.
Ash Removal with Coal
When burning coal it is important to keep the grate free of ash, and vital that ash does not build
up under the grate to prevent the flow of incoming air cooling the grate itself. Binding agents are
sometimes used in manufactured smokeless fuels which will increase the amount of ash produced,
and until the ash content of your fuel is ascertained regular checks must be made to ensure the ash
pan is not over filled. Always be certain the ash pan has sufficient capacity before riddling the grate.
Do not use the ash pan withdrawing tool to carry the ash pan, use both hands and wear heat proof
gloves. Leaving the ash door of the stove open allows an uncontrolled air supply into the stove and
may allow the stove to burn at a rate far beyond its design capability. Make it a practice never to
leave this door open.

Choices of Fuel
Wood
All wood will burn, and whilst various tables tabulate the calorific values of the wood obtained from
different tree species, the most important difference between woods is their moisture content. Until
the moisture has been driven off from the wood it will remain below its combustion temperature,
and even when the outer skin is dry 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 mixing with the products of combustion, form
creosote and other undesirable substances which will eat away the fabric of the flue, build up to
eventually block the flue and will at any time 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 18 months -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.
Coal
We recommend burning deep mined anthracite, a natural hard coal which is classified as being a
smokeless fuel; specifying a size above "beans" will prove to be the most visually attractive and
efficient burning. 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. The difficulties associated with burning ordinary bituminous coal make it totally unsuitable
for reliable burning in any stove.
DO NOT BURN petroleum based fuels such as petro-coke, they may seriously damage your stove.
The manufacturer of other blended 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 grate system containing chrome steel.
Lignite
Lignite is obtainable in briquette form and is the mid point of wood being transformed into coal. It
behaves very much like wood and should be burned as wood, although setting the thermostatic
damper just off its minimum setting will keep the fire bed alive.
Peat
Peat is a very good fuel, although very bulky, and burns very well. It should be treated as for wood.

Cleaning the stove
Cleaning the Glass
Properly operated, your glass will remain clean, and any slight sooting which may occur when the
stove is lit will normally clear when the stove heats to its operating temperature. Before attempting to
clean your stove’s glass the stove must be extinguished and allowed to cool, as for safety reasons
it would be foolish to attempt cleaning when the stove is operating or still hot.
The glass in your stove is specially formulated to withstand the very high temperatures and
proprietary glass cleaners 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 dishwashing 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.
The Stove Body
Dusting the stove may be carried out when the stove is at its minimum heat output temperature,
using light strokes of a real bristle paint brush. Thorough cleaning, or any attempt to remove marks
on the stove body must only be done when the stove is cold. Stoves with an enamel finish should
be cleaned with a damp cloth, or very gentle use of a cleaner recommended for enamel finishes. It
should be noted that even approved cleaners will damage the highly polished finish of the stove if
used too vigorously. All traces of the cleaner must be removed before the stove is lit and no finishing
polishes must ever be used as these will leave unsightly streaks on the stove when it becomes
hot.
Stoves with a cast black finish must never be cleaned with a cloth as the texture of the paint will
abrade and collect lint from the cloth which will be almost impossible to remove. Vigorous brushing
with a stiff bristle paint brush will remove all dust, but where the paint is marked, the stains are better
obliterated with a spray of suitable stove paint rather than attempts made to clean them off. Suitable
paint may be purchased from a stove shop or direct from Euroheat.
Brass Fittings
Any proprietary brass cleaner may be used to clean the brass on the stove, but care must be taken
to ensure the polish does not come into contact with the stove enamel or the black cast finish, where
it will leave a stain.
The Flue
The installation guide recommends that your chimney is lined and insulated because the efficiency
of the stove allows only the minimum of heat to be lost through the flue. A badly insulated or an
oversized flue may cause problems if humid flue gases 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
discoloration 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.

Other Maintenance
The stove must be cleaned of ash and any tarring as often as your use of the stove and fuel dictate.
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 Euroheat are fitted.
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. If the stove does
not have a boiler fitted it should be left with one of its air supplies open to encourage the evaporation
of any rain that may enter the flue. The stove interior should be coated with a moisture repellent such
as WD40. All operating mechanisms should be lubricated with oil; this applies particularly to the door
handle shafts and latching blades.
Removing Baffle
The stove has a baffle at the rear of the combustion chamber which simply lifts upwards and can be
removed. With the baffle removed all ash deposits in the stoves flue ways can be removed.
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.
Enamel Finish
If your stove has an enamel finish you will notice, after the stove has been used several times,
it develops what is called a “crackle” pattern in the enamelling. This is caused by the different
expansion rates between the enamel and the cast iron, it is normal and should not be regarded as
a fault or indicating that the stove is beginning to shed its finish.
Warranty Registration
Thank you for choosing a Harmony stove. It has been constructed with the utmost care and with
the finest materials; we hope it gives you many years of pleasurable warmth. Included with your
appliance is a registration form. Please ensure this is fully completed by your installing engineer
and returned to Euroheat within 14 days of installation. The free 10 year Technical help can only
authorized, if the stove is registered with Euroheat by returning the registration form.
WARNING
A properly installed stove does not emit smoke or fumes into the room. If your stove suddenly emits
either, open a window, turn down the firing rate of the stove and leave to burn out. A flue blocked
whether because of accumulated soot or even by a dead bird will cause any fire to fill the house with
carbon monoxide; do not treat it merely as a nuisance.
