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.

E & OE Instructions Part number IN1011 Ed.3

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.

E & OE Instructions Part number IN1011 Ed.3

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.

For additional chimney information see the installation guide included with the appliance or contact

the Solid Fuel Association (see yellow pages).

E & OE Instructions Part number IN1011 Ed.3

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.

HAVE YOUR STOVE FITTED AND MAINTAINED BY EXPERIENCED PROFESSIONALS.
