Termo ISOTTA – DSA20 7199701 Rev.05 – EN2. TECHNICAL DESCRIPTIONLa Nordica thermoheating stoves are suitable for heating homes using a centralised heating system made up fromradiators or heat convectors entirely or partially replacing the traditional gas or diesel oil boiler. They are ideal forholiday apartments and week-end homes or as auxiliary heating throughout the entire year.Wooden logs are used ad fuel.The fireplace is found inside the boiler, is built in 4 mm thick steel and is reinforced using welded nails. The water inthe heating system circulates in the boiler, which absorbs the heat produced in the fireplace.A swivelling, removable grid is found inside the fireplace.The hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C). This allows a wonderfulview on the burning flames and avoids any possible output of sparks and smoke.The heating of the environment is made:a) radiation: the heat is radiated into the environment through the panoramic window and the hot externalsurfaces of the thermoheating stove;b) by conduction: radiators or heat convectors of the centralised system fed by hot water produced by thethermoheating stove itself.The thermoheating stove has regulators for primary and secondary air, with which the combustion air is adjusted.PRIMARY air controlWith the primary air control (Picture 1 A) is adjusted the passage ofair through the ash drawer and the grate in the fuel direction. Theprimary air is necessary for the combustion process. The ashdrawer must be regularly emptied, so that the ash does not obstructthe primary air entry. Through the primary air the fire is also keptalive.During wood combustion, the register of primary air must beopened only for a while, because otherwise the wood burns fastand the stove may overheat. For the correct arrangement, see thetable on chapter 10.SECONDARY air controlOver the door of the hearth there is the secondary air control(Picture 1 B). This regulator must be open (the lever must bemoved to the right), especially for wood combustion, so that un-burnt carbon does not undergo a post-combustion. See chapter 10.Through this register it is possible to adjust the power of the stove.Leaving it slightly open, according to the flue of the chimney, it ispossible to keep the glass clean.3.
