TermoSovrana DSA32 7094211 – EN14.2. GLASS CLEANINGThrough a specific secondary air inlet, the formation of deposits of dirt, on the door glass, is effectively slowed down.It cannot, though, ever be avoided with the use of solid fuels (e.g. damp wood) and this should not be considered adefect of the appliance.IMPORTANT: the cleaning of the panoramic glass must only be carried out when the thermocooker is cold, inorder to prevent it exploding. Do not use cloths or products which are abrasive or chemically aggressive.The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary airregulator, enough draught of the chimney-flue and the presence of combustion air are the essential elements for theoptimal functioning of the appliance and for the cleaning of the glass.GLASS BREAKAGE: as the glass parts are in ceramic glass, resistant up to a sudden thermal change of750°C, they are not subject to thermal shocks. Their breakage can only be caused by mechanical shocks(knocks or violent door closing etc.). Therefore replacement is not covered by the warranty.14.3. ASH DRAWER CLEANINGAll LA NORDICA thermocookers have a furnace grill and a drawer for ashcollection. It is advisable to empty the ash drawer periodically and prevent itfilling up completely, so as not to overheat the grill. In addition, it isadvisable to always leave 3-4 cm of ash in the furnace.CAUTION: the ash removed from the furnace must be replaced in arecipient for fireproof material equipped with an airtight cover. Therecipient must be placed on fireproof flooring, away from flammablematerials until the ash is completely out and cool.IMPORTANT: if for whatever reason the grill is removed from the furnace,take care to reassemble it with the wider part of the slit facingdownwards. This is to aid furnace cleaning (Picture 13).14.4. MAINTENANCE ON THE WATER SYSTEMWith the system switched off, once a year carry out the following checks:• Check the operation and efficiency of the blowdown and safety valves. If they are defective, contact yourauthorised installer. IT IS STRICTLY FORBIDDEN TO REMOVE OR TAMPER WITH THE SAFETYDEVICES.• Check the thermal insulation of the filling pipe and the safety pipe.• Make sure that the system is filled and under pressure, checking the water level in the expansion tank; alsocheck that it is working properly and check the efficiency of the safety pipe.15. SUMMER SET ASIDEWARNING: The system should be kept constantly full of water even in periods in which the use of the wood burningstove/cooker is not required. During the winter, inactivity must be faced with the addition of antifreeze.After having cleaned the furnace, the chimney and the flue, ensuring total elimination of the ash and other residues,close all the furnace doors and respective registers and disconnect the appliance from the chimney.It is advisable to carry out the flue cleaning operation at least once a year; in the meantime, check that the seals arein good condition as, if not perfectly intact, they do not guarantee good appliance operation! In this case, it isnecessary to replace them.If appearance is to be maintained over time, protect the cast iron parts with neutral Vaseline.16. CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUEThe flue gas channel is the stretch of piping which connects the thermoproduct to the flue. In the connection, thesesimple but extremely important principles must be respected:• under no circumstances use a flue gas channel with a diameter less that that of the exhaust clamp with whichthe thermoproduct is equipped;• each metre of the horizontal stretch of the flue gas channel causes a slight loss of head which must becompensated if necessary by elevating the flue;Picture 13
