TermoSovrana DSA7094211 – EN 29• the construction materials of the products in question are not homogeneous; in fact cast iron and steel parts existside by side.• the temperature to which the body of the product is subjected is not homogeneous: from zone to zone, thetemperatures recorded vary from 300 °C to 500 °C;• during its life, the product is subjected to alternate cycles of ignition and switch-off during the same day and tocycles of intense usage and complete rest as the seasons change;• the new thermocooker, before it can be defined as “tested”, must be subjected to various start up cycles in orderto allow all the materials and the varnish to complete the various elastic stresses;• in particular at the beginning, it is possible to notice the emission of smells which are typical of metals subjectedto great thermal stress and varnish which is still fresh. This varnish, despite being baked at 250°C for a few hoursin the manufacturing process, must exceed the temperature of 350°C several times and for a certain duration,before incorporating itself perfectly with the metal surfacesIt therefore becomes important to follow these small precautions in the ignition phase:1. Make sure that there is significant air turnover in the place where the appliance is installed.2. When lighting for the first few times, do not load the combustion chamber excessively (about half of the quantityshown in the instruction manual) and keep the product lit for at least 6-10 hours continuously, with the registersopen less than shown in the instruction manual.3. Repeat this operation at least 4-5 times, according to your availability.4. Subsequently load more (nevertheless following the descriptions in the instruction booklet regarding themaximum load) and if possible, keep ignition periods long, at least in this initial phase, avoiding short on-offcycles.5. When lighting for the first few times, no object must be resting on the thermocooker and in particular onenamelled surfaces. Enamelled surfaces must not be touched during heating.6. Once the “testing” phase has passed, it is possible to use your product like you would a car engine, avoidingabrupt heating with excessive loads.To light the fire, it is suggested to use small wood pieces together with paper or other traded lighting means. It isforbidden to use any liquid substance as for ex. alcohol, gasoline, oil and similar.The openings for air (primary and secondary) must be opened together, the smoke register is to be adjusted for thecooker function, i.e. the command bar must be pushed to the back of the cooker (the eventual butterfly valve which isfound on the exhaust smoke pipe is also to be opened).When the wood starts to burn, it is possible to load other fuel, close the primary air register and check combustionusing secondary air following the instructions in paragraph 10. During this phase, never leave the cookerunsupervised.CAUTION: when lighting for the first few times, it is possible to find consistent flue gas condensation withslight leakage of water from the thermocooker; this is a phenomenon which should disappear in a veryshort time. If it results as persistent, it will be necessary to have the flue draught checked.Never overload the thermocooker. Too much fuel and too much air for combustion can cause overheatingand therefore damage the thermocooker. The damage caused by overheating is not covered by the warranty.10. NORMAL OPERATIONWARNING: 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 appliances with automatic door closing (type 1), must operate, for safety reasons, with the furnace door closed(with the exception of the fuel loading phase or any ash removal).Appliances with non-automatic door closing (type 2), must be connected to their own flue. Operation with the dooropen is only allowed under supervision.IMPORTANT: For safety reasons, the furnace door must only be open during the ignition phase and forloading wood whilst during operation and periods of non-use it must remain closed.The nominal calorific power of the thermocooker is reached with a minimum draught (depression) of 17 - 20 Pa (=1.7-2mm water).It is therefore necessary to always use the thermocooker with the door closed to prevent the “forge” effect. Thethermocooker must never be overloaded. Too much fuel and too much air for combustion can causeoverheating and therefore damage the thermocooker. The damage caused by overheating is not covered bythe warranty.
