GB CHOICE OF FUEL All sorts of logs, such as birch, beech, oak, elm, ash, conifers and fruit trees can be used as fuel in the tiled stove. Different types of wood have different density, the higher the density the higher the energy value. Oak, beech and birch have the highest density. Fresh wood is about 50 per cent water. Some of the water circulates freely between the fibres and some of the water is bound in the cells. The wood must always be dried so that the free water evaporates. The timber is ready for use when the moisture content has fallen below 20 %. If wood with a higher moisture content is lit, a large part of the energy content of the wood is used boiling off the water. If the wood is damp, the combustion is also poor, layers of soot and tar build up in the chimney and could, at worst, lead to a chimney fire. In addition, it causes the glass of the tiled stove to soot and may cause discomfort to those living nearby. To ensure thoroughly dry wood, the wood should be cut in the winter and stored, well aired, under a roof. Never cover the wood pile with a tarpaulin to the ground. The tarpaulin will then act as a sealed cover and the wood will be prevented from drying. Always store a small amount of wood indoors for several days before use, so that the surface moisture has time to evaporate. The moisture content can be easily checked by weighing a small test piece of wood before and after it has been dried at an oven temperature of 80° C for 24 hours. Calculate the moisture content by dividing the weight of evaporated water by the total weight of wood including water. m -m Moisture content in %: before after m x 100 before Warning! Under no circumstances may pressure impregnated wood, painted or glued wood, chipboard, plastic or colour brochures be used as fuel in a tiled stove. All these materials can create hydrochloric acid and heavy metals that are damaging both to the environment and the tiled stove. Hydrochloric acid can also attack the steel in the chimney or the mortar in a stone built chimney. The correct size of wood is also important for combustion. The size of the wood should be: Kindling wood: Finely chopped wood Length: 25 -35 cm Diameter: 2 - 5 cm Weight per lighting: 2.5 kg (approx. 10 - 12 finely chopped pieces) Wood: Chopped wood Length: 25 - 35 cm Diameter: 7 - 9 cm Normal weight: 2.0 kg (2-3 logs per load) Max weight: 3.0 kg (3-4 logs per load) 12 kg per lighting (followed by at least 9 hours cooling) 24 kg per 24 hours 18 LIGHT THE FIRE AS FOLLOWS: It is important that the correct amount of wood is used, especially when lighting. If you are lighting the fire for the first time you should use a set of scales to see how much 2.5 kg kindling is. Also check what the normal and maximum weights look like. The tiled stove is only intended for use with the door closed. Always open the door carefully and slowly to prevent blow back because of the changing pressure in the stove. The function of tiled stoves differs depending on the draft conditions in the chimney. Achieving the correct setting for the combustion air damper and start damper and the appropriate amount and size of wood usually takes a few attempts. Lighting Important! Note that if too little kindling is used when lighting, or if the wood is too thickly cut, the fire box will not reach the correct operating temperature. Incorrect lighting can lead to poor combustion with heavy sooting and may result in the fire going out when the door is shut. If your house has mechanical exhaust air ventilation you will need to open a window near the tiled stove before lighting the fire. Leave the window open for a few minutes until the fire has caught. In order to obtain a good bed of embers, there should always be a thin layer of ash and charred pieces in the tiled stove. 1. Open the combustion air damper, flue damper and start damper to the fully open position. 2. Place some newspaper or a fire lighter block, and approximately 2.5 kg kindling in the middle of the tiled stove. The wood should be piled alternately across and lengthways. 3. Light the fire. Leave the door ajar with an opening of about 10 mm to the holder. 4. When the fire has caught fully after approx 10-15 minutes, close the doors completely. With good draft in the chimney the start damper is moved to approx 1⁄4 of the fully open position. 5. When the first wood refill is made and has caught, the start damper can be closed. How early the start damper can be closed varies. This depends on how hot the tiled stove is regarding lighting and on the draft conditions in the chimney. Wood loading Just before the fire has burnt down and the flames have gone out it is time to add more wood. 1. Open the door handle slightly and let the vacuum in the firebox equalise for a few seconds before opening the door completely. 2. Add 2-3 logs of a combined weight of approx 2-2.5 kg. Lay the logs so that there is space between them. This is to achieve the correct air mixture. Then close the door. 3. The combustion damper must be completely open for 2- 3 minutes until the logs turn black and catch fire. If you wish for slower combustion, the supply of combustion air can now be reduced. The conditions for controlling combustion vary depending on the temperature in the tiled
stove and the draft in the chimney. Remember that the fire must always burn with bright clear flames. 4. Add two more loads of wood of 2-2.5 kg each. Then allow the tiled stove to give off the accumulated heat for 9-12 hours before repeating the lighting procedure. Do not exceed the permitted amount of wood of 12 kg per lighting instance with a following cooling period of at least 9 hours. Maximum permitted weight of wood is 24kg over 24 hours. 5. When the glow has gone out the combustion damper and the flue damper can be shut. This is to prevent heat leakage through the chimney during the cooling period. Important! It is important that the wood catches fire quickly. Quick lighting is achieved by opening the combustion air damper fully or by leaving the door ajar for a moment. Pyre lighting causes thick smoke and can cause quick gas ignition with the risk of damage to property and personal injury. It is important that the flue damper is not closed until the glow in the tiled stove has gone out. DAMPER Below the door of the tiled stove there is a control for the combustion damper. The control is open when it is pulled out. The combustion air damper must be fully out during lighting and at the start of the first loading. The supply air can first be controlled when the tiled stove and chimney are hot. How much the supply air can be controlled depends on how hot the stove is and the strength of the draft in the chimney. When the glow has gone out, the combustion damper can be shut completely. There are two damper controls on the side of the upper section of the tiled stove. The damper control that moves in and out controls the start damper. The start control is open when it is pulled out. The twist control controls the flue damper. When the control is vertical the flue damper is open, when it is horizontal it is closed. A label with three positions of the flue damper and the start damper is supplied with the tiled stove. The label is static adhesive and is applied to the side of the tiled stove next to the flue damper by moistening the surfaces with water. • START. When starting, the start control must be open and pulled out. The flue damper must be vertical and open. • NORMAL FIRE. For normal burning the start damper must be closed and pushed in. The flue damper must be vertical and open. • CLOSED. After completed burning, the start damper must be closed and pushed in. The flue damper must be horizontal and closed. 1 GB GENERAL A correctly lit tiled stove gives good heating economy and warmth for a long period of time. The tiled stove should be lit regularly with cooling down periods of 9-12 hours. It is therefore recommended that fires are lit twice a day, which gives even heating for a long time. The fire should not be too big. Normal fires require about 2 kg of wood per load. The recommended amounts are 2.5 kg of kindling followed by three loads of wood, which totals approximately 9 kg per fire. Externally, the tiled stove should never be hotter than one can touch without getting burnt, which is about 65°C. The largest permitted weight of wood is 3 kg per wood load and maximum 12 kg per lighting followed by a cooling period of at least 9 hours. The maximum weight of wood per 24 hours is 24 kg and refers to cut birch or other broadleaf wood with 18 % moisture content. When lighting the same weight of conifer wood, significantly higher stove temperatures are reached. Exceeding the largest permitted weight of wood can cause the tiled stove and nearby building parts to overheat. The service life is shortened and parts of the tiled stove may be damaged and the warranty will no longer apply WHEN THE TILED STOVE IS NEW Allow the tiled stove to rest for a week or so before lighting for the first time to give the adhesive time to harden. Only light the stove for a max 2 hours the first few times. When the tiled stove is lit for the first time a particular smell may be detected, which indicates an oil coating and excess paint on the panels. After a number of fires the smell will disappear. MAINTENANCE OF TILED STOVE During burning the glass can become sooty, even when burning dry wood with a moisture content of 15 - 20%. Wiping with dry paper is often sufficient when cleaning regularly. If the soot has been on the glass for longer it can be removed using cleaning agent or a specific soot removal agent. These cleaning agents can be purchased at your local supermarket or your local tiled stove dealer. ● Never use cleaning agents that contain any abrasives, these can damage the glass. ● Ensure that the no embers remain when removing ash from the stove. The ash must be stored in a fireproof container with a lid for at least least a week before being disposed of. ● The tiling is cleaned using soapy water, dry using dry cloths. ● Checking the gaskets is important from a combustion point of view, because worn gaskets reduce combustion efficiency when the tiled stove burns leaked air. ● Painted parts of the tiled stove can be cleaned with a damp cloth and, if necessary, a little washing-up liquid. Brass components must be polished regularly to retain their shine. Damage, such as scratches, to painted parts can be repaired using Cronspisen touch up paint. Contact your dealer.
