We hope you will enjoy your new Hase stove. [. . . ] Light the ignition material at several places. Once the wood is lit sufficiently on all sides close the ash drawer, and some 10-15 minutes later the primary air slide (I Set secondary air slide (II) later to ideal position (after around 15-20 min. Place logs with one end to the front of fire box. Open fire box door Wood should be added when the flames of the prior fire are about to die Close fire box door Set primary air valve (I) to zero Close fire box door Do not attempt to slow down the combustion by reducing the air supply. Emptying the Ash Drawer For safety`s sake, please make sure that you only dispose of ashes once they are cold. Slide the lid onto the ash drawer so that it is closed; this prevents ashes from flying around, which in turn means your home stays clean. to place the ash drawer back into the stove , proceed in the reverse order. Piled up ashes can prevent or even block the primary air supply to the stove. Ensure that the ventilation path for the primary air between the ash drawer and the bottom of the ash compartment remains clear. When heating with wood, this can result in an incomplete burning process and pose the risk of explosive-like combustion of the accumulated wood gases (deflagration). The Combustion Process A piece of wood burns in three phases. In a wood fire, however, these processes take place both consecutively and simultaneously 14. For the evaporation to occur, the wood must be supplied with heat during the warming up phase; this is achieved by using small wood logs. 2 Degasification Phase At temperatures of between 100°C and 150°C, the contents of the wood start (slowly at first) to disintegrate and gasify and the wood begins its thermal decomposition. at temperatures above 150°C , the gas development increases strongly. The proportion of volatile components makes up around 80% of the wood substance. At a temperature of about 225°C (ignition temperature), the actual combustion begins with the ignition of the resulting gases and the release of heat. There must be an adequate supply of oxygen available for this purpose. The reaction process is now so rapid that the largest amount of heat is released at this point; flames can reach temperatures of up to 1100°C. These burn slowly, almost without flames, at a temperature of approx. Crucial to a clean and efficient combustion process is a complete (as possible) chemical reaction of the wood gases with the oxygen in the combustion air. With your Hase stove, the combustion air is pre-heated and guided into the fire box via wide air inlet openings, enabling a good and thorough mixing of the gases with the air. [. . . ] The sealing strips are wearing parts and thus have to be replaced in line with the frequency of use. Possible Problem The wood does not light or lights only slowly. The wood burns without a bright, yellow flame, smoulders or even goes out. Possible Cause - The wood is too thick. [. . . ]
