TermoSovrana DSA30 7094211 – ENThe emission of heat from the furnace is adjusted with the registers placed on the front of the thermocooker. Thesemust be open according to calorific need. The best combustion (minimum emissions) is reached when, loading wood,most air for combustion passes through the secondary air register.IMPORTANT: during normal cooker operation, the register lever, Picture 1 pos. E must remain completely inserted(pushed inwards on the cooker). In this way, excessive fuel consumption is avoided (register closed).The register regulation necessary in order to obtain nominal calorific output is the following:Fuel PRIMARY air SECONDARY airWOOD OPEN OPENThe intensity of combustion and therefore the calorific output of your thermocooker are influenced by the chimney.Good chimney draught requires less regulation of the quantity of combustion air, while insufficient draught requires alarger quantity.IMPORTANT: to check that combustion is taking place correctly, verify that the smoke which comes out of thechimney is transparent. If it is white, it means that the thermocooker is not regulated correctly or the wood is toowet; if, on the other hand, the smoke is grey or black, this means that combustion is not complete (a greaterquantity of secondary air is necessary).11. OVEN USEAfter having cleaned the furnace grill, load the fuel. Thanks to the supply of air for combustion, the oven temperaturecan be influenced slightly. Sufficient chimney draught and very clean channels for the flow of scorching flue gasaround the oven are essential for a good cooking result. The flue gas register must be completely drawn towards thefront of the thermocooker.The oven pan can be placed on various levels. Thick cakes and large roasts should be inserted at the lowest level.Thin cakes and biscuits go on a medium level. The highest level can be used for heating or browning.The thermocooker is equipped with a cast iron furnace grill which can be removed using a specific handle. The upperposition optimises the use of the hotplate while the lower one optimises water and oven heating.12. ELECTRICAL POWER SUPPLY FAILUREIn the event of an unexpected electrical power supply failure during normal system operation, it will be necessary tocarry out these simple manoeuvres to prevent the water in the boiler starting to boil as a consequence of the lack ofpump operation.1 Close the primary and secondary air regulators completely in a way to suffocate the flame as much as possible.2 Open the oven door in order to favour the elimination of the internal heat.3 Open the flue gas register by pushing the knob placed on the right hand side of the frame; in this way, it willdeviate the residual heat still produced towards the chimney.13. OPERATION IN TRANSITION PERIODSWARNING: For no reason turn on the fire before the system has been completely filled with water; doing socould cause serious damage to the entire structure. The system should be kept constantly full of water evenin periods in which the use of the wood burning stove/cooker is not required. During winter any non activityshould involve the addition of anti- freeze.During transition periods when the external temperatures are higher, if there is a sudden increase of temperature itcan happen that the combustion gases inside the flue cannot be completely sucked up.The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequentlyand increase the air for the combustion. Then, load a reduced quantity of fuel in order to permit arapid burning (growing up of the flames) and the stabilization of the draught.Then, check that all openings for the cleaning and the connections to the stack are air-tight.13.1. NORMAL COOKER USE.WARNING: For no reason turn on the fire before the system has been completely filled with water; doing socould cause serious damage to the entire structure.If the thermocooker is only to be used for cooking foods, for example during the summer period, it is necessary toraise the moveable grill to the highest level in order to exclude as much as possible the exchange surface capable ofpassing heat to the water; the flue gas register (Picture 1 pos.D) must be completely positioned to the RIGHT in orderto favour the exhaust of hot flue gases after having heated the cast iron hotplate.
