IMPORTANT

.  The installation of this appliance must comply with all current BS 8303 local regulations, including those referring to national and European Standards before it can be operated. The stove is not suitable for a shared ﬂue. However, for England and Wales, only, the coming into force on 1st April 2002 of SI 2002 No 440 exempts the householder from this legal requirement for the installation of solid fuel ﬁred appliance whose rated heat output is 50kW or less in a building having no more than 3 storeys (excluding any basement) if a Competent Engineer is employed who is registered under the Registration Scheme for Companies and Engineers involved in the Installation and Maintenance of Domestic Solid Fuel Fired Equipment operated by HETAS Ltd. These registered Competent Engineers may also carry out associated building work necessary to ensure that the installed appliance complies with Building Regulations without involving the Local Authority Building Control Department.

 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.

 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. If it is possible for children or inﬁrm adults to come into contact with the stove, ﬁt a suitable ﬁre guard.

 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 be sought from a qualiﬁed engineer.

 The user should be advised that 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.

 Our range of stoves is capable of operating with outstanding efﬁciency if the ﬂue system is correct. Because so little heat is wasted to the ﬂue it is possible that moisture within the products of combustion will condense if the heat losses within the ﬂue way are too great and allow the ﬂue gases to cool. For this reason we recommend that the stove is ﬁtted with a suitable ﬂue liner, the same diameter as the ﬂue spigot, to prevent the possibility of acidic damage to the fabric of the chimney and damage to the stove which will reduce the longevity of the stove.

 When correctly installed, the stove is designed to produce heat, safely. It cannot do so if the installation is less than absolutely stable, constructed of materials suitable for such an installation and consideration has not been given to the possibility of people with less than ideal common sense operating it.

 Have the existing chimney swept by a chimney sweep. Although you will be lining the chimney, any deposits left in the chimney will cause problems and may become a ﬁre hazard.

 Your attention is drawn to the precautions and responsibilities under the Health and Safety at Work Acts, and whatever new legislation being introduced during the life of this document.

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.

E & OE Instructions Part number IN1244

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.

Multifuel And Wood Stoves

E & OE Instructions Part number IN1244

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.

Peat (Should Not Be Burnt in a Smokeless area)

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.

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.

E & OE Instructions Part number IN1244

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 “softwood”. Typically all broad leaf trees that lose their leaves in the winter are called hardwoods, and the evergreen conifers are called softwoods. 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 as 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.

E & OE Instructions Part number IN1244

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.

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 1000-1200° 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.

Grate Cover Plate

Your HWAM stove is supplied with a loose cover plate for the riddling grate. This is a 3 mm thick steel plate. It is placed on top of the riddling grate and prevents the embers from falling into the ash pan. The cover plate is raised approx. 8 mm above the grate, thus ensuring that the automatically controlled primary combustion air is distributed evenly at the base of the combustion chamber.

E & OE Instructions Part number IN1244

First Lighting of the Stove

When you light the stove for the ﬁrst few times it should be with small ﬁres increasing in size, as all the materials must be given time to adapt to the effects of heat. The paint on the body of the stove will be fully hardened after the stove has been cured, however the door and the ash pan should be opened very carefully before this as there will otherwise be a risk that the gaskets will stick to the paint.

Curing

The paint may initially give off unpleasant fumes and an odour, so make sure that the room is well ventilated. The paint will be soft, so care must be taken with the stove for the ﬁrst 6-8 ﬁrings. This is called curing and is not a fault of the stove and will stop.

Soapstone Finish

Soapstone must gradually be conditioned to heat. Soapstone may contain water, which is why you must be cautious when you ﬁre your stove for the ﬁrst time to keep the ﬁre low for the ﬁrst two hours. This will allow the soapstone to dry slowly and release the tension in the stone without any damage to the soapstone.

We recommend following the procedure below:

First ﬁring

Place two lightly crumpled sheets of tabloid sized newspaper in the stove. Then lean some small, extremely dry kindling with a diameter of between 3–5cm vertically against the paper in a conical formation, leaving space between each piece and light it. Make sure the air controls are set to maximum and leave the door of the stove slightly open. Keep the door slightly ajar until the kindling is burning brightly, then shut the door.

Do not leave the stove unattended with the door open.

After it has been lit and when it is burning well, add a similar amount of kindling.

Adjust the air inlet control to mid/low setting. Using small logs keep the ﬁre burning low for two hours then gradually build up the ﬁre.

Always use the glove supplied with the stove when loading with fuel or operating any of the controls or handles.

E & OE Instructions Part number IN1244

Wearing the stove glove place a few logs larger than kindling wood over, but not smothering the kindling.

When the previous loading of wood is burning brightly add two larger split logs to bridge the ﬁre. Always avoid putting wood directly onto wood burning with ﬂame, try and leave air space under the wood for the ﬂame to form, because the new, cold log will tend to cool the ﬁre.

Reduce the burn rate control setting when the ﬁre is established to the desired heat output and set the air wash control to the mid setting. See the individual lighting and operating instructions for the stoves on the following pages.

Putting new logs bark side down, will give you both maximum efﬁciency and best visual effect as it begins to burn.

At the rear of the combustion chamber you will observe that there are a series of holes or slots, these are there to allow air into the combustion chamber and should NOT be covered at any time

Important!

Do not open the ash pan door when lighting the stove and always keep it closed when the stove is in use, otherwise you may destroy the automatic combustion control.

E & OE Instructions Part number IN1244

General Maintenance of the Stove

Ash Removal

The ash pan should NOT be removed and emptied when the stove is operating. Removal of the ash pan when the stove is lit will allow unregulated air to enter the stove which can damage the automatic combustion control system. Do not allow ash to block the combustion air slots/holes at the rear of the combustion chamber. We recommend that these slots/holes are vacuumed regularly.

The embers within the ashes may remain alight for up to 24 hours after the stove has gone out, so they must be disposed of in a non combustible container.

Cleaning the Stove

Cleaning the Glass

Before attempting to clean your stove’s glass the stove must be extinguished and allowed to cool, as for safety reasons it would be potentially unsafe 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 dish washing 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.

Check the condition of the seals around the glass regularly for signs of leakage, replace only using the manufacturer’s sealing gaskets.

The Stove Body

Any maintenance of the stove should only be carried out when it is cold. Daily maintenance is limited to vacuum cleaning the stove externally, using the soft brush attachment. You can also dust the stove using a dry, soft cloth or brush, but only when the stove is cold.

Maintaining Painted Surfaces

If the stove is scratched, or the paint ﬂakes off over time, it can easily be repaired with ﬁne emery paper and a special spray paint.

Spray Paint

Order product number HW99-0043BL for black surfaces, and HW99-0043GRY for grey surfaces

Once a year, the stove should be thoroughly serviced by a suitably qualiﬁed heating engineer. The combustion chamber should be cleared of ashes and soot. Door and ﬁttings should be lubricated using a copper-based grease. The rope seals on the doors and glass should be replaced before the start of a new heating season. The instructions for this can be found in the installation instructions supplied with the stove.

E & OE Instructions Part number IN1244

Maintenance of Soapstone

What is soapstone?

Soapstone is a natural material, a natural stone, which absorbs and stores heat effectively. The result is that the heat from the stove is given off over a longer period of time. There are different types of soapstone. The type is determined by the composition of minerals of the stone e.g. talcum powder, magnesium and chloride. This results in different shades and structures in areas and lines of the stone. Soapstone must gradually be conditioned to heat. Soapstone may contain water, which is why you must be cautious when you ﬁre your stove the ﬁrst 3 times. For each time the temperature may be increased. This will allow the soapstone to dry slowly and release the tension in the stone without any damage to the soapstone. See the ﬁrst lighting instructions on page 23.

Maintenance of soapstone

Cleaning the soapstone can be done with a pH neutral (pH7) cleanser.

• The soapstone must be at room temperature.

• Moisten the stain with undiluted cleanser and leave it to soak for a few minutes.

• Wash the surface with clean, hot water.

Difﬁcult stains can be removed carefully with acetone or colourless spirit. Be careful not to get these solvents onto the painted surfaces of the body of the stove as they will remove the paint.

Alternatively the stains can be sanded with very ﬁne sanding paper. If the soapstone is sanded with water and wet sanding paper it is possible to obtain a smooth surface.

Repair of small scratches or strokes, can be made by using very ﬁne sanding paper.

• The soapstone must be at room temperature.

• Sand the surface with very ne sand paper until the scratch has disappeared – remember to use a sanding block

to ensure an even surface.

• Polish with water and wet very ne sand paper if a smooth and even surface is desired.

In case you have more than one soapstone on your stove, all stones can be polished to an even result.

E & OE Instructions Part number IN1244

Operational Problems

Blackened glass

The wood is too damp. Only use wood stored for at least 12 months under cover and with a moisture level not exceeding 25%.

Smoke in the room when opening door

Open the door slowly, a few millimetres at ﬁrst, then gradually to allow the pressure changes within the stove to equal out. Insufﬁcient chimney draft. See page 10, Flue Draught Measurement or contact a chimney sweep. Soot door leaking or dislodged. Replace or reﬁt. Never open the door when there are still ﬂames on the wood.

Uncontrollable combustion

Faulty seal in door or ash pan. Fit new seal. If there is an excessive chimney draft, it may be necessary to ﬁt a draught stabilizer or a stabilizing cowl (See IN1173).

If the steel plates in the combustion chamber develop scales or become deformed, this is due to excessive heat caused by over ﬁring the stove. This can be caused by excessive chimney draught, incorrect operation of the stove or incorrect fuel type, e.g. a petroleum coke based product. If over ﬁring is evident contact your local retailer who can advise you on the most suitable remedy.

Fulmination

A stove may sometimes give off a loud noise, and this is known as fulmination. Most stoves will make a “ticking” sound when heating up and cooling down. In a few cases this normal ticking will be replaced by a number of loud bangs. This is due to tension in the construction which is released during heating and cooling and has no practical signiﬁcance for the function of the stove and does not constitute a safety risk or a fault in the construction of the stove. In some cases it may be possible to remove this tension by allowing the stove to heat up very quickly.

Cracked glass

The glass in the stove door is a special ceramic glass that can stand extremely high temperatures, but it is particularly sensitive to knocks and blows at high temperatures and when heating up and cooling down. So if the door is closed with a bang or is subjected to knocks and blows in other ways, there is a high risk that the glass will crack – typically at the corners where it is secured to the door. If an accident should happen it is possible to order a repair kit containing glass, gaskets, etc., and instructions for replacing the glass from your local retailer or directly from Euroheat.

White or opaque glass

If the glass becomes white and opaque and cannot be cleaned as normal, it may have been damaged. The glass in the stove door is a special ceramic glass that can tolerate gentle ﬂame impingement, however ﬁerce ﬂames which are directed onto the glass will cause it to revert irreversibly to its original opaque state. Never burn any manufactured wood based products bonded with adhesive such as chipboard, burn only natural unadulterated wood as manufactured by nature and only smokeless fuels which have been approved for use in an enclosed appliance.

E & OE Instructions Part number IN1244

The combustion chamber lining has cracked or broken

The ﬁreproof Skamolex lining in the combustion chamber is made of vermiculite, which is a specially manufactured material that can withstand very high temperatures and also provides efﬁcient insulation and thereby ensures the optimum temperature and combustion in the combustion chamber. The material is porous and cannot withstand knocks or blows. Cracks are usually caused by a blow to the material with a piece of wood or similar. This is not detrimental to the insulating effect as long as the stones are still correctly placed in the stove. The liners should be replaced when they have been worn down to approximately half their original thickness. After this they will no longer provide proper insulation and therefore do not ensure the correct combustion temperature, nor can they protect the stove against the high temperatures in the combustion chamber.

The door will not open

If the door cannot be opened, this will normally be due to the heat of and tension in the material. Wait until the stove is cold and try again. In very rare cases the closing mechanism on the door may have broken. This will make it necessary to obtain the help of your stove distributor.

Rust

The stove will not rust if it is correctly installed and connected. When the inside of a stove rusts this is often due to the fact that it is exposed to dampness from the chimney when not in use during periods of warm wet weather. To minimise this risk, the stove can be lit during these periods to ensure that it is thoroughly dry inside. In some properties, where the temperature is often low indoors during the winter, the temperature in the combustion chamber can become so low that water from the stationary air will condense on the metal surface of the stove. This water may lead to a rust attack.

To avoid this we recommend ensuring there is a draught through the stove, possibly by allowing the air supply to the stove to remain slightly open during the winter. The metal surfaces within the stove can also be sprayed with “WD40” or a similar water repellent to protect them from the effects of moisture.

If the outside of the stove rusts, this will generally be because it has been stored in damp surroundings for a longer period of time and water has been able to form on its surface. If this does occur, it is possible to order a spray paint to match the colour of the stove.

Technical Details Intermittent Operation

Intermittent operation is when the appliance is used for short ﬁring periods for example 45 minutes to 2 hours. This is a common operation in warmer weather such as cold spring evenings. The information provided below where indicated as HETAS approved is from the current CE standards EN 13240:2001 and EN 13240 A2:2004. The test fuel is wood.

* Air requirement equivalent area. Building regulations Document J, advises that an air supply should be installed for appliances with a heating output over 5kW. Document J indicates that there should be sufﬁcient advantageous air for heating outputs below this amount. With modern properties this may not always be the case and/or more free air may be required. Continuous or intermittent operation will result in different heating outputs due to the nature of the fuel and the appliance. If in doubt increase the suggested area listed or contact your HETAS approved engineer for assistance.

Hearths

The stove should stand wholly above a hearth constructed of suitably robust materials and should be able to accommodate the weight of the appliance and its unsupported ﬂue components. The materials should conform to local Building Regulations and British Standards.

If the stove is not to stand in an appliance recess, a hearth made of non-combustible board/sheet material or tiles of at least 12mm thick may be used as long as the ﬂoor can accommodate the weight of the appliance and its unsupported ﬂue components. If it is installed on a wooden ﬂoor or similar, the ﬂoor must be covered with a non-combustible material, a minimum of 12mm thick, to a distance of 300mm in front of the stove and 150mm to each side measuring from the closed door of the combustion chamber.

The Hwam range of stoves have been tested and conform to standards where the hearth temperature does not exceed 100°C This means a hearth of 12mm of noncombustible material can be used.

Do not be tempted to ﬁt the stove into an unsuitable ﬁreplace. Beyond the requirements of Building Regulations and access to facilitate servicing the stove, providing a setting which will compliment a stove is not a luxury, it is the practicality of making the most of an investment. A good builder or ﬁreplace specialist will be able to transform even the most utilitarian of ﬁreplaces. Whether altering its proportions to those of the “Golden Mean” ideal, see below, or exposing a wooden or stone lintel or simply removing superﬂuous detailing for a comparatively small cost, and the result will be a pleasure for many years.

“Golden Mean”

1. The stove must always stand perfectly level. The provision of a suitable level hearth within the recess is an important consideration when planning a ﬁreplace.

2. Sufﬁcient space should be allowed for service work.

3. At least the minimum clearance from inﬂammable materials and conforming to the current Building Regulations.

4. Sufﬁcient space around the stove so that the controls may be operated without the risk of injury to the operator.

5. Mounting brackets should be installed to facilitate the secure ﬁtting of a ﬁre guard, if one is to be ﬁtted to protect the young, elderly or inﬁrm.

6. Curtains and soft furnishings should be a minimum of 1m from the stoves body or the surface temperature of these furnishings must not exceed 65°C.

7. The mounting of expensive paintings, mirrors and plasma screen televisions above a ﬁreplace is not recommended.

Fitting The Internal Parts

Before the stove is installed, you must ensure that all the internal parts are ﬁtted correctly.

7 8

1, Bafﬂe plate should be placed on the steel rail and the holder at the front middle.

2. The bafﬂe plate is suspended on three hooks beneeath the top plate. One of these hooks has an additional ﬂap that is bent upwards for protection when in transport. This should be removed with a screwdriver before installation.

3. Grate cover plate. Should always cover the grate.

4. Rear ﬂue outlet. If your stove was ordered as top ﬂue outlet this will be factory ﬁtted and sealed.

5. Removable rear plate. Covers the automatic system, this must always be ﬁtted if the stove is installed near a combustable wall.

6. Loose heat shield under the ash pan. This can be used as a lid when the ash pan is removed for emptying.

Grate Cover Plate

Fresh Air System

Instead of letting the air from the room into the stove for combustion, it is possible to take in fresh air from outside and introduce this directly via a duct into the back or the base of the stove.

Today, many modern dwellings are so airtight to conform with building regulations that it is an advantage to attach a fresh air intake to the stove. This continually supplies the air for combustion while the stove is in use but as the air is ducted directly into the back of the stove it stops cold fresh air mixing with the warm air in the room chilling the room or causing draughts.

Fresh Air Systems are available. See www.euroheat.co.uk for further information.

E & OE Instructions Part number IN1244

Automatic Combustion Control

30°

Lift off the rear panel. On a cold stove, the starting point of the mechanism is controlled. The starting point on a cold stove is about 30° above horizontal. It should move easily and spring loaded when you push it, no matter if the stove is cold or hot. With a rising or falling temperature it should move gradually. The damper plates must be dry and clean and slide together unhindered. Control bars and slide gates may have to be lubricated with a proprietary lubricant such as WD40 or a PTFE based product such as Amberglide.

Insulation (Skamolex)

The mica board insulation material of the combustion chamber may, in time, become worn and damaged. Cracks in the insulation have no effect on the efﬁciency of the stove. The insulation should be replaced, however, when it is reduced to less than half the original thickness due to wear and tear.

Maintenance Instructions

Flue Draught Measurement

A ﬂue draught which is too low will result in the stove being difﬁcult to light, responding only slowly to demands for increased output and unable to reach its full heating output. If this is the case rectiﬁcation work of the chimney construction should be undertaken. A ﬂue draught which is too high will cause difﬁcult control conditions, and makes it possible to over ﬁre the stove, which can seriously damage it. In this instance a ﬂue draught stabiliser may need to be ﬁtted or if it is wind assisted excessive ﬂue draught a stabilizing cowl may need to be ﬁtted.

The negative pressure created within the combustion chamber of the stove must be measured using a test hole drilled into the ﬂue, as close to the stove as possible and before any draught stabilizer that may be ﬁtted to the ﬂue. To ensure a constant air inlet size the readings should be taken with the air inlet controls set at maximum.
