GIADA7196001 Rev.05 – EN 216. CONNECTION TO THE CHIMNEYFor safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of thefuel or for removing the ashes, while during the operation and the rest, the door of the hearth must remain closed.The appliances with constructive system 2 must be connected to their own flue. The operating with open door isallowed under supervision. The connection pipe to the flue must be the shortest possible, right, tight and according tothe current regulations.The connection to the chimney must be performed with stable and strong pipes (we recommend a thickness of 2mm). The pipe for smokes exhaust must be fixed hermetically to the chimney. The diameter inside the connectionpipe must correspond to the external diameter of the smokes exhaust small trunk of the stove. This is ensured bypipes according to DIN 1298.ATTENTION: Eventual flammable pieces in the area of 20 cm round the connection pipes must be changed withfireproof and not sensitive to heat materials.For a good operation of the equipment it is essential that in the installation place it is introduced sufficient air forcombustion (see chapter 7).The depression on the chimney (draught) should be 12 Pa (=1.2 mm of water column). The measurement must bedone always with the equipment hot (rating calorific value). When the depression exceeds 17 PA (1.7 mm of watercolumn) it is necessary to reduce the same with the installation of an additional flue adjuster (butterfly valve) on theexhaust pipe or in the chimney.For safety reasons the door of the hearth may be opened only during the loading of fuel. The hearth must remainclosed during the operation and the periods of non use.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 of air isintroduced in the installation room itself.In case of tight doors and windows (for example houses built according to the energy saving criteria) it is possible thatthe air entrance is not guaranteed, compromising the draught, the welfare and the security of the people. It isnecessary to guarantee a further air entrance through an external air intake, to be positioned in the nearby of theappliance or through air connection towards outside or a near ventilated room, with the exception of thermal unitsplace or garages (FORBIDDEN).The connection pipe must be flat with a minimum diameter of 120 mm, a maximum length of 4 m and with no morethan 3 bends. If there is a direct connection with the outside it must be endowed with a special windbreak.The air entrance for combustion into the installation place must not be closed during the operation of the stove. It isabsolutely necessary that in the environment in which the stoves operate with the natural flue of the chimney, it isintroduced as much air as necessary for the combustion, i.e. up to 20 m3/hour.The natural recirculation of air must be ensured by some fixed openings on the outside. The size of the necessaryopenings for air is fixed by the relevant prescriptions. Ask information to your chimney sweeper. The openings shouldbe protected with grids and should never be obstructed.An extraction hood (aspirating) installed in the same room or in a roomnearby, causes depression with output of combusted gasses (smoke,smell) even if the hearth door closed. As consequence a contemporaryoperation of the hoods is not possible.The depression in an extraction hood can at worst hypothesis,transforms the flue into an external air intake, by sucking thesmokes of the rooms with dangerous consequences for the people.OPTIONALFor a better comfort and corresponding oxygenation of environment, thestove combustion air can be directly withdrawn at the outside. In order todo that, the stove can be connected to the external air socket by anoptional junction (Picture 8- A) (Kit Ø 120 ).Picture 8A
