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 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 burn anything but natural wood or approved coals on this appliance.

 Due to the 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 anyway, even when the stove is cold.

 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 stove to emit smoke, do not treat it as merely a nuisance, this smoke will indicate that carbon monoxide is being emitted into the room. Turn the stove to its minimum ﬁring rate, open windows and allow the stove’s fuel to burn out before closing the windows. Do not re-light the stove without consulting a qualiﬁed engineer.

 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, see installation guide for boiler cleaning information, 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.

 Harmony 1 with 3kW boiler and Harmony 3 with 11kW boiler.

We would recommend that after the ﬁrst weeks of use the cast iron top plate is removed and that the accumulation of soots is monitered, then after two weeks it is inspected again. This will allow you to gauge the frequency that the boiler will need to be cleaned, see the installation guide for boiler cleaning information.

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.

Wood and Multifuel 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 you 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. The air is supplied as slowly as possible so as not to blow out any established ﬂames. 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.

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.

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 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 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.

Choice of Fuels

Bituminous House Coal

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.

Smokeless Coal

We recommend burning deep mined anthracite, a natural hard coal which is classiﬁed as being a smokeless fuel; specifying the sizes of “small nuts” or “large nuts” (preferably large nuts) will give most visually attractive and efﬁcient burning. Smaller sizes than this will tend to choke the air ﬂow too easily making long burning times without attention problematic. 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.

House Coal

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. However it is not classiﬁed as a smokeless 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. Most manufactured coal contains some petroleum based coke ingredients. Before burning them please conﬁrm there suitability with the coal manufacturer.

Instructions Part Number IN1145 Ed A

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. All logs should be split and ideally, quartered.

Stove Model Ideal Log Length Maximum Log Length

Harmony 1 with 3kW boiler 11 inches, 280mm 18 inches, 457mm

Harmony 1 with 6kW boiler 10 inches, 250mm 17 inches, 432mm

Harmony 3 with 7.5kW boiler 17 Inches, 432mm 22 Inches, 558mm

Harmony 3 with 11kW boiler 14 Inches, 356mm 19 Inches, 482mm

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, 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.
