Termo ISOTTA – DSA26 7199701 Rev.05 – ENCHIMNEY CAPS - DISTANCES AND POSITIONING UNI 10683/98Inclination of theroofDistance between the roofridge and the stackMinimum height of the stack(measured from the outlet)αααα A (m) H (m)15°< 1.85 m 0.50 m above the roof ridge> 1.85 m 1.00 m from the roof30° < 1.50 m 0.50 m above the roof ridge> 1.50 m 1.30 m from the roof45° < 1.30 m 0.50 m above the roof ridge> 1.30 m 2.00 m from the roof60° < 1.20 m 0.50 m above the roof ridge> 1.20 m 2.60 m from the roof6. CONNECTION TO THE CHIMNEYThe appliances with automatic door closure (type 1) must function, for safety reasons, with the fireplace door closed(with exception of the fuel loading phase or removal of ash).The appliances that do not have automatic door closure (type 2) must be connected to their own flue. Functioning withthe door open is only allowed under surveillance.The thermoheating stove has an upper fumes pipe. The junction pipe for the connection to the chimney must be theshortest possible and the junction points of the single pipes must be hermetic. The connection to the chimney must beperformed with stable and strong pipes (we recommend a thickness of 2 mm). The pipe for smokes exhaust must befixed hermetically to the chimney. The diameter inside the connection pipe must correspond to the external diameterof the smokes exhaust small trunk of the stove. This is ensured by pipes according to DIN 1298.ATTENTION: whenever the connection passes particular composites of inflammable materials, all inflammablematerials within a range of 20 cm around the pipe must be replaced by non-flammable and heat resistantmaterials.For a good operation of the equipment it is essential that in the installation place it is introduced sufficient air forcombustion. This means that, through suitable openings, air must recirculate for the combustion, even with doors andwindows closed (see chapter 7).The depression on the chimney (CHIMNEY EFFECT) must be 17 – 20 Pa (=1.7 – 2 mm of water column). Themeasurement must be done always with the equipment hot (rating calorific value). When the depression exceeds 20PA (2 mm of water column) it is necessary to reduce the same with the installation of an additional flue adjuster(butterfly valve) on the exhaust pipe or in the chimney.7. AIR ENTRANCE INTO THE INSTALLATION PLACE DURING COMBUSTIONAs the stoves take their combustion air from the installation place, it is MANDATORY 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 25 m3/ora.
