DOMIcompact F 24 B
Connection to collective flues or single flues with natural draught
If you are then going to connect the DOMIcompact F 24 B 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 standards and rules in force.
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 and heat and waterproof for the con-
densate
• Have a circular or square cross-section (some hydraulically equivalent sections are permissible), with a
vertical progression and with no restrictions
• Have the ducts conveying the hot fumes adequately distanced or isolated from combustible materials
• 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.
