Wood cooker – ROSA - ROSETTAInstructions for installation, use and maintenance – EN – Rev.05 236. CONNECTION TO THE CHIMNEYFor safety reasons the door of the appliances with constructive system 1, must be opened only for theloading of the fuel or for removing the ashes, while during the operation and the rest, the door of the hearthmust remain closed.The appliances with constructive system 2 must be connected to their own flue. The operating with opendoor is allowed under supervision. The connection pipe to the flue must be the shortest possible, right, tightand according to the current regulations.The connection to the chimney must be performed with stable and strong pipes (we recommend athickness of 2 mm). The pipe for smokes exhaust must be fixed hermetically to the chimney. The diameterinside 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 10 - 12 Pa (=1.0 - 1.2 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.Picture 7CHIMNEY CAPS - DISTANCES AND POSITIONING UNI 10683/98Inclination of the roof Distance between the roofridge and the stackMinimum height of the stack(measured from the outlet)αααα A (m) H (m)< 1,85 m 0,50 m above the roof ridge15° > 1,85 m 1,00 m from the roof< 1,50 m 0,50 m above the roof ridge30° > 1,50 m 1,30 m from the roof< 1,30 m 0,50 m above the roof ridge45° > 1,30 m 2,00 m from the roof< 1,20 m 0,50 m above the roof ridge60° > 1,20 m 2,60 m from the roof>_ A>A0,5 mH min.α (2)roof(1)ridge axis
