Chimney Cap - Nordica TERMOCAMINO 650 Anleitung

The draught created by your flue must be sufficient but not excessive.
An overly large cross-section may present a volume too large to heat and therefore cause problems in the
operation of the appliance; to prevent this, duct the flue for its entire height. A cross-section too small
causes a decrease in draught.
The flue must be adequately distanced from flammable or combustible materials by means of
insulation or an air gap.
It is forbidden to run it inside the piping of air feed systems or channels. It is also prohibited to make
moving or fixed openings on the flue for the connection of other different devices.

5.1. CHIMNEY CAP

The flue draught also depends on the suitability of the chimney cap.
It is therefore indispensable that the outlet cross-section be twice the internal cross-section of the flue when
making the chimney cap by hand.
As it will always rise above the roof ridge, the chimney cap must also ensure exhaust even in the presence
of wind (see Picture 9)

The chimney cap must meet the following requirements:
•
The internal cross-section must be equivalent to that of the chimney.
•
The useful outlet cross-section must be twice that of the internal cross-section of the flue.
•
It must be constructed in such a way as to impede the penetration of rain, snow, or any foreign body
into the flue.
•
It must be easy to inspect for any maintenance and cleaning operations.

(1) In the case of adjacent flues, one chimney cap must rise above
the other by at least 50 cm to prevent the transfer of pressure
between the flues.
10 m
(1) The chimney cap must not have any obstacles within 10 m from
walls, pitch, and trees. In such case, it must be raised at least 1 m
above the obstacles.
The chimney cap must rise above the roof ridge by at least 1 m.
(2) Hand made
chimney cap. The
right outlet cross-
section must be at
least twice the
internal cross-
section of the flue,
ideally 2.5 times.
