4.6.3 Permitted connection types
Type COB-2-15/20/29/40
Appliance type
1, 2, 3
B23, B33, C33x, C43x, C53, C53x, C63x, C83x, C93x
Operating mode
Open ue Yes
Room sealed Yes
Can be connected to
Moisture-resistant chimney B23, B33, C83x
Balanced ue chimney C43x
Air/ue gas routing C33x, C53x, C93x
Certied air/ue gas routing C63x
Moisture-resistant ue B23, C53x, B33
1
An x indicates that all components of the ue are surrounded by combustion air and meet higher requirements for gas tightness.
2
For types B23 and B33, the combustion air is drawn from the installation room (open ue combustion equipment).
3
For type C, the combustion air is drawn through a sealed system from the outside (room sealed combustion equipment).
Table 4.8 Permitted connection types
The following balanced ues or standard ues with CE-0036-CPD-9169003 certication may be used
(Table 4.9 Permissible air/ue gas routing lengths [m]):
– Flue DN60 – Flexible ue DN83
– Concentric balanced ue DN60/100 – Flue DN110
– Flexible ue DN60 – Flexible ue DN 110
– Flue DN80 – Concentric balanced ue DN110/160
– Concentric balanced ue DN80/125 – Flue DN 160 (for cascade operation)
– Concentric balanced ue (on an external wall)
DN80/125
The necessary type plates and certicates are included with the relevant WOLF accessories.
4.6.4 Air/uegasroutinglengths
The calculation was made taking the pressure conditions into account (geodetic height: 325 m). The
specied lengths refer to concentric balanced ues and standard ues and apply to original WOLF
components only.
