INSERTO 60 – 70 – 70 To – 70 Pr – 70 H496090710 R – EN 19The minimum section must be 4 dm2 (for example 20 x 20 cm) for appliances whose duct diameter is lowerthan 200 mm, or 6.25 dm2 (for example 25 x 25 cm) for appliances with diameter greater than 200 mm.The draught created by the flue must be sufficient, but not excessive.A too big flue section can feature a too big volume to be heated and consequently cause difficulties in the operation ofthe appliance; to avoid this, tube the flue along its whole height. A too small section causes a decrease of the draught.The flue must be properly spaced from any flammable materials or fuels through a proper insulation or an aircavity.It is forbidden to let plant piping or air feeding channels pass in the same flue. Moreover, it is forbidden to createmovable or fixed openings on the same for the connection of further other appliances.5.1. CHIMNEY CAPThe draught of the flue depends also on the suitability of the chimney cap.Therefore, if it is handicraft constructed, the output section must be more than twice as big as the internal section ofthe flue.Should it be necessary to exceed the ridge of the roof, the chimney cap must assure the discharge also in case ofwindy weather (Picture 7).The chimney cap must meet the following requirements:• have internal section equivalent to that of the stack.• have a useful output section twice as big as the flue internal one.• be manufactured in such a way as to prevent the penetration of rain, snow, and any other foreign body in theflue.• be easily checkable, for any possible maintenance and cleaning operation.Picture 7Picture 8Picture 9(1) Industrial chimney capwith pre- fabricatedelements – it allows anexcellent discharge of thesmokes.( 2) Handicraft chimneycap. The right outputsection must be at leasttwice as big as theinternal section of the flue(ideal value: 2.5 times).(3) Chimney cap for steel fluewith internal cone deflector ofsmokes.50 cm (1) In case of flues side by side, a chimney cap must be higher thanthe other one of at least 50 cm in order to avoid pressure transfersbetween the flues themselves.(1) The chimney cap must not show hindrances within 10 m from walls,pitches and trees. Otherwise raise it of at least 1 m over the hindrance.The chimney cap must exceed the ridge of the roof of at least 1 m.2 m 10 m1m
