CORTINA – CORTINA Forno24 7196100 Rev.08 – ENinside the connection pipe must correspond to the external diameter of the smokes exhaust small trunk ofthe stove. This is ensured by pipes according to DIN 1298.ATTENTION: Eventual flammable pieces in the area of 20 cm round the connection pipes must bechanged with fireproof and not sensitive to heat materials.For a good operation of the equipment it is essential that in the installation place it is introduced sufficientair for combustion (see chapt. 7).The depression on the chimney should be 12 - 13 Pa (=1.2 – 1.3 mm of water column). The measurementmust be done always with the equipment hot (rating calorific value). When the depression exceeds 17 PA(1.7mm of water column) it is necessary to reduce the same with the installation of an additional flueadjuster (butterfly valve) on the exhaust pipe or in the chimney.For safety reasons the door of the stove must be opened only for the loading of the fuel or forremoving the ashes, while during the operation and the rest, the door of the hearth must remainclosed.7. AIR ENTRANCE INTO THE INSTALLATION PLACE DURING THE COMBUSTIONAs the stoves take their combustion air from the installation place, it is essential that a sufficient quantity ofair is introduced in the installation room itself.In case of tight doors and windows (for example houses built according to the energy saving criteria) it ispossible that the air entrance is not guaranteed, compromising the draught, the welfare and the security ofthe people. It is necessary to guarantee a further air entrance through an external air intake, to bepositioned in the nearby of the appliance or through air connection towards outside or a near ventilatedroom, with the exception of thermal units place or garages (FORBIDDEN).The connection pipe must be flat with a minimum diameter of 120 mm, a maximum length of 4 m and withno more than 3 bends. If there is a direct connection with the outside it must be endowed with a specialwindbreak.The air entrance for combustion into the installation place mustnot be closed during the operation of the stove. It is absolutelynecessary that in the environment in which the stoves operatewith the natural flue of the chimney, it is introduced as much airas necessary for the combustion, i.e. up to 20 m³/hour.The natural recirculation of air must be ensured by some fixedopenings on the outside. The size of the necessary openings forair is fixed by the relevant prescriptions. Ask for information toyour chimney sweeper. The openings should be protected withgrids and should never be obstructed.An extraction hood (aspirating) installed in the same room or in aroom nearby, causes depression with output of combustedgasses (smoke, smell). As consequence the extraction hoodsshould not work at the same time of the stove.The depression in an extraction hood can at worst hypothesis, transforms the flue into an externalair intake, by sucking the smokes of the rooms with dangerous consequences for the people.OPTIONALFor a better comfort and corresponding oxygenation of environment, the stove combustion air can bedirectly withdrawn at the outside. In order to do that, the stove can be connected to the external air socketby an optional junction (Picture 8 - A) ( Kit Ø 120 ).8. ADMITTED/NOT ADMITTED FUELThe fuels admitted are wood logs. One must use only logs of dry wood (water content max. 20 %). Thesize of wood logs should be 30 cm’s long and 30 cm’s max in circumference.Picture 8A
