exhaustion is carried out by means of an outlet duct and an air intake from outside. It is
recommended that the position at the exhaustion duct exterior portion should be in
accordance with the data of the following figures and table:

K from the floor level
2500
L from a vertically/horizontally-arranged outlet or pipe (**)
300
M from a front surface at a distance of 3 metres from the exhaust gas outlet
2000
N like the previous one, but with opening
3000
(*) In so far the balcony width does not exceed 2000 mm.
(**) If the pipe constructive materials were sensitive to the action from the flue gases, this distance should be
longer than 500 mm.
