GB 30 Choice of fuel All types of wood such as birch, beech, oak, elm, ash, softwoods and wood from fruit-trees can be used as fuel in the stove. Different types of wood have different densities. The denser the wood, the greater the energy value. Beech, oak and birch, for example, are all very dense. Fresh wood comprises 50% water, some of which circulates freely between the fibres, while the remainder is stored in the cells.
GB 31 Stoking the fire When the stove is new Important! For effective control of the heat output, it is important to have a thick bed of glowing embers and a high temperature in the fire-box. LE K When the fire has burned down to the embers, it is time to stoke it with more wood. 1. Open the door a fraction and allow the pressure in the fire-box to even out for a few seconds before opening the door fully. 2. Stoke with 2 or 3 logs that together weigh between about 1.5 and 2.5 kg.
GB 32 Possible causes of operating problems and remedies Poor draught in the stove after installation Abnormally large soot deposits on the glass • Check that the length of the chimney corresponds to the requirements: it should rise 1 metre above the ridge of the roof, and its total length should be at least 3.5 metres • Check that there is no blockage in the chimney that prevents smoke and fumes from escaping, and that there is no house or tree nearby that is affecting the wind around the chimney.
