TermoSovrana DSA7094211 – EN 276. CONNECTION TO THE CHIMNEYCookers with automatic door closing (type 1) must operate, for safety reasons, with the furnace door closed (exceptduring the fuel loading or ash removal phases).Cookers with non-automatic door closing (type 2) must be connected to their own flue.Operation with doors open is only allowed when supervised.The connection pipe to the flue must be as short as possible, straight and watertight.Connection must be carried out with stable and robust pipes (we recommend a thickness of 2 mm) and behermetically secured to the flue. The internal diameter of the connection pipe must correspond to the externaldiameter of the cooker flue gas exhaust stub pipe (DIN 1298).CAUTION: if the connection passes particular compounds of flammable material, in the radius of 20cm around thepipe, all flammable material must be replaced by fireproof, heat resistant materials.For correct appliance operation, it is essential that sufficient air for combustion is introduced into the place ofinstallation (see paragraph 7).IMPORTANT: the unused flue gas exhaust hole must be covered with its respective cap (See chapter 18).The chimney pressure (DRAUGHT) must be at least 17-20 Pascal (=1.7-2 mm water). The measurement must alwaysbe carried out when the appliance is hot (nominal calorific power). When the pressure exceeds 20 Pascal (2 mmwater), it is necessary to reduce it through the installation of an additional draught regulator (butterfly valve) on theexhaust pipe or in the chimney.7. AIR FLOW IN THE PLACE OF INSTALLATION DURING COMBUSTIONAs the thermocookers draw their combustion air from the place of installation, it is essential that in the place itself, asufficient quantity of air is introduced. If windows and doors are airtight (e.g. built according to energy saving criteria),it is possible that the fresh air intake is no longer guaranteed and this jeopardises the draught of the appliance andyour health and safety. It is therefore necessary to guarantee a supply of fresh air through an external air inlet placedPicture 9CHIMNEY POT DISTANCES AND POSITIONING: UNI 10683/98Roof slope Distance between ridge andchimneyMinimum chimney height (measured from theoutlet)αααα A (m) H (m)15°< 1.85 m 0.50 m beyond the ridge> 1.85 m 1.00 m from the roof30°< 1.50 m 0.50 m beyond the ridge> 1.50 m 1.30 m from the roof45°< 1.30 m 0.50 m beyond the ridge> 1.30 m 2.00 m from the roof60°< 1.20 m 0.50 m beyond the ridge> 1.20 m 2.60 m from the roof>_ A>A0.5 mmin.
