Connection to collective flues or single flues with natural draught
The UNI 10641 standard prescribes the design criteria and checking the internal dimensions of the
collective flues and single flues with natural draught for units with a sealed chamber equipped with a
fan in the combustion circuit.
If you are then going to connect the
Domicompact F 30 D Boiler
to a collective flue or a single flue with
natural draught, the flue must be expressly designed by professionally qualified technical personnel in
conformity with the UNI 10641 standard.
In particular, flues must have the following characteristics:
• Be sized according to the method of calculation stated in the standard
• Be airtight to the products of combustion, resistant to the fumes, heat and waterproof for the conden-
sate
• Have a circular or quadrangular cross-section (some hydraulically equivalent sections are permissible),
with a vertical progression and with no constrictions
• Have the ducts conveying the hot flue gases adequately distanced or isolated from combustible mate-
rials
• Be connected to just one unit per floor, for at most 6 units in all (8 if there is a compensation duct or
opening)
• Have no mechanical suction devices in the main ducts
• Be at a lower pressure, all along their length, under conditions of stationary operation
• Have at their base a collection chamber for solid materials or condensation of at least 0.5 m, equipped
with a metal door with an airtight closure.
