Chimney system working with negative pressure does not has the silicon seal.
The available diameters to use with negative pressure are:
160, 180, 200, 220, 230, 250, 280, 300, 350, 400, 450, 500, 550, 600, 650, 700.
Positive pressure working:
When single wall system made in stainless steel Aisi 316L (1.4404) works with positive pressure (P1 class), it has the following designation in
accordance with the standard EN 1856-1:2003 :
Chimney System EN 1856-1
Where:
T200: temperature class
P1: pressure level
W: condensate resistance, the chimney system is fit for wet working
V2: corrosion resistance class
L50050: specification of internal wall material; material: 1.4404 (AISI 316L), minimum thickness: 0,50 mm
O60 :
the chimney system is not sootfire resistant and the minimum distance from combustible materials shall be
60 mm
Chimney system working with positive pressure has the silicon seal to obtain a perfect tightness of elements.
The available diameters for positive pressure working are:
80, 100, 120, 130, 140, 150, 180, 200, 220, 230, 250, 280, 300, 350, 400.
4) IDENTIFICATION METAL PLATE OF CHIMNEY SYSTEM
At the end of installation, the installer shall compile the identification metal plate of chimney system (supplied by manufacturer) and shall put it
near or at the base of single wall chimney system.
On this metal plate shall be written the installer data , the designation of installed chimney ( according to standard
nominal diameter and the distance from combustible materials declared by manufacturer.
Roccheggiani product designation according to the standard EN 1443 shall list the following information:
Single wall in stainless steel Aisi 316L (1.4404):
negative pressure working:
working:
Chimney System EN 1443
Where:
T250, T200: temperature class
P1, N1: pressure level (P1 is the positive pressure class, N1 is the negative pressure class ) O: non sootfire
resistant
W: condensate resistance, the chimney system is fit for wet working
2: corrosion resistance class for Italian market (note: C2 class applicable for French market) R00: the value of
thermal resistance is zero
C60: the installation distance of chimney system from combustible materials shall be 60 mm
