Air/flue gas routing
Single boiler system:
Implementation versions, condensing boiler
B23 Flue in a duct and combustion air directly via the boiler (open flue)
Connection to a moisture-resistant flue gas chimney with horizontal
B33
connection line
Combustion air supply and flue gas routing via the roof in a common
C33
pressure range
Vertical concentric roof outlet through a pitched or flat roof, vertical
C33 concentric air/flue gas routing for installation in a duct (balanced
flue)
Connection to a moisture-resistant balanced flue chimney (balanced
C43
flue)
Terminals of the combustion air and flue are in different pressure
C53
ranges (balanced flue)
Connection to flue on an external wall with horizontal eccentric
C53
connection line (length 2.5 m) (balanced flue)
The flue gas system has not been tested and certified with the appliance.
C63
It must meet the building requirements of the relevant country.
Connection to a moisture-resistant chimney and combustion air
C83
through an external wall (balanced flue)
Vertical flue for installation in a duct with horizontal eccentric
connection line, balanced flue ventilation air supply DN200. The
C93
terminals are in the same pressure range, combustion air supply via
existing duct (edge length in mm)
* Applies to horizontal connection line DN 200 with length of 2 m and an 87° bend (corresponds to 3 m effective length)
Comments:
•
Length of connection line: 2 m, 1 additional 87° bend (corresponds to 3 m effective length)
Duct cross-section = minimum annular gap to DIN 18160 Part 1
•
Available fan draught: MGK-2: 10 - 150 Pa
(maximum length corresponds to the total length from the appliance to the flue terminal)
Note:
•
Systems C33 and C83 are also suitable for installation in garages.
•
Where necessary, adapt the installation examples to the relevant Building Regulations and requirements in your country/region.
Discuss any questions relating to the installation of inspection covers and ventilation air supplies with your local flue gas
inspector.
•
The length dimensions refer to concentric balanced flue systems and flues, specifically only to original Wolf components.
•
The following balanced flues or flues with CE-0036-CPD-9169003 certification may be used:
- Flue DN 160, DN 200, DN 250 and DN 315
- Concentric balanced flue DN 250/350 and DN 315/400
•
The necessary identification labels are supplied with the Wolf accessory concerned.
•
Please also observe the installation information supplied with the accessories.
