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 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.

 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 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.

 The Hwam models Beethoven, Vivaldi, Mozart, Ravel and Hwam 30 are considered suitable for exemption under the Clean Air Act only when burning untreated dry wood. The appliance should only be used to burn wood or authorised fuels. For details of authorised fuels that are suitable for the appliance please contact your appliance distributor.

 The Hwam models Beethoven, Vivaldi, Mozart, Ravel and Hwam 30 are considered as exempt for use in smoke control areas if they have been modiﬁed to ensure the air wash/secondary air control cannot be fully closed. If this modiﬁcation has not been carried out by the manufacturer or Distributor then the appliance is not considered exempt under the Clean Air Act.

Before Operating this Appliance

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.

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 gases, 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 gases it will ignite. Unburned gases 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 gases 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 gases 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 gases 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 gases 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.

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.

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” 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. 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 considered an approved 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.

Smoke control area`s

The Hwam models Beethoven, Vivaldi, Mozart, Ravel and Hwam 30 are only considered suitable for exemption under the Clean Air Act when burning untreated dry wood. The appliance should only be used to burn wood or authorised fuels. For details of authorised fuels that are suitable for the appliance please contact your appliance distributor.

Always riddle the grate before putting on loadings of coal to give the initial release of gases sufﬁcient air with which to burn; failure to do so may allow the stove and ﬂue to ﬁll with gases 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 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 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 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.

Stove Controls

Burn Rate Control

The rate at which the stove burns is controlled by adjusting the air entering the stove. Moving the control from minimum to maximum increases the size of the air inlets, primary or secondary air, in the automatic combustion system.

For the position of this control on the various stoves see the following pages which describe the lighting and operating of the stoves.

The Automatic Combustion System

A bi-metalic coil heated by the ﬂue gases moves a cam which raises and lowers, dependant upon the heat of the ﬂue gases, a plate or plates which exposes or closes 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 10001200° Celsius there is only a need for air above the ﬁre, i.e. secondary air.

3) The burning-out phase. The temperature falls, the air supply above the ﬁre is gradually reduced, and the lower damper opens, i.e. primary air.
