5.6 Installing the concentric
connection, 60/100 mm diameter, to the
air/flue system for negative pressure
5.6.1 Installation instructions
Installation example:
Markings have been assigned to the air/flue system in ac-
cordance with EN 1443 and these indicate that the system
complies with the fundamental requirements of the construc-
tion products directive. The air/flue system is not approved
as part of the boiler.
The air/flue gas chimney must be designed and approved for
negative-pressure mode by the manufacturer.
The air/flue gas chimney's data plate is marked for operation
with condensing boilers and a flue gas temperature of at
least 120 °C.
▶ Take into consideration the regulations with regard to fire
resistance.
The Vaillant ecoTEC gas-fired wall-hung boilers that are
mentioned in these installation instructions are approved
in accordance with the European and British standard "PD
CEN/TR 1749: 2005, European scheme for the classification
of gas appliances according to the method of evacuation of
the combustion products (types) C43".
The length of the air/flue pipe must not exceed 1.4 m and
three elbows. This corresponds to a maximum length of 3.4
m for the C43 connection.
