In the horizontal runs the duct must be slightly slanted (about 10°) and directed upwards to vent the air easily from the room to the outside. Filter version (K) The air is filtered through a carbon filter (for its installation see paragraph "Carbon filter") and recirculated into the room through the grating on the lower side of the chimney. If the hood is not supplied with carbon filter, then it must be ordered and mounted. This version is used when there is no exhaust duct for venting outdoors or when it is impossible to install one. The use of an unprotected flame is dangerous for the filters and could cause fires. ­ The hood cannot be connected to flues of other appliances that run on energy sources other than electricity. ­ When the hood is used at the same time of other appliances that run on energy sources other than electricity, provision must be made for an adequate air supply.
