If you are then going to connect the ECONCEPT SOLAR ST 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 cur-
rent standards and be suitable for airtight chamber units equipped with a fan.
In particular, flues must have the following characteristics:
•
Be sized according to the method of calculation stated in the current standards.
•
Be airtight to the products of combustion, resistant to the fumes and heat and waterproof for the condensate.
•
Have a circular or quadrangular cross-section, with a vertical progression and with no constrictions.
•
Have the ducts conveying the hot fumes adequately distanced or isolated from combustible materials.
•
Be connected to just one unit per floor.
•
Be connected to just one type of unit (or all and only forced draught units or all and only natural draught units).
•
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 equipped with a metal door with an airtight closure.
