46ENERGA 70-55 TUNNEL8 GENERAL HINTS8.1 TIPS• Burn dry wood only. Damp wood not only burns poorly, it causes more pollutionin the appliance (window), the chimney, your room (when opening the door of theappliance, for instance) and the environment. Wood can only be classified as dry if ithas been stored under a Dutch barn for at least two years (not covered with plastic).Never use painted or impregnated wood. The gases emitted when burning painted orimpregnated wood are aggressive and will affect the appliance, the environment andyour health.• Ensure that your fire burns well. The smoke generated should be translucent or whiteand the windows of the fire will remain clean. We recommend that you do not ‘pinchoff’ your fire (by closing all air openings). Doing so will hinder combustion which,apart from polluting the atmosphere, will lead to deposits of soot and tar in yourchimney (which, unchecked, will increase the risk of chimney fire).• Keep the door shut when the fire is burning. Doing so improves the performance ofyour fire 8 - 10 times, benefiting the environment and the heat in your home (lesstopping up, see section 8.2). You will also prevent fire damage from any particles thefire ‘spits’ out (this is a particular problem with softwood from conifers). If your floorcontains flammable material, an extra floor plate is required.• Avoid lighting a fire in misty or still conditions. If the wind is still, there is hardlyany draught in the cold chimney. As smoke is heavier than air, there is a chancethat smoke will enter the room. If there is mist in the air, smoke coming out of yourchimney will cool quickly and fall, causing problems in your area.• Do not extinguish your fire with water - let it burn out. The part of the inner lining thatis in direct contact with the fire is clad with fire-resistant material. Sudden changes intemperature may lead to it deforming or cracks appearing.• Chimney fire.If, despite all the precautions, a fire should occur in the chimney (you generally noticethat because of a roaring sound in the chimney), do the following:• Immediately shut the chimney flap (if fitted).• Immediately shut the air supply to the fire.• Call the fire brigade (( 112).• Quickly quench the fire in the appliance with sand or soda in order to preventsmoke in your house.• Never use water to put out the fire.• Ventilate.• If there has been a fire in the chimney, have it swept and inspected for damageand leakage.
