Installation instructions
Installation example:
Markings have been assigned to the air/flue gas system in
accordance with EN 1443 and these indicate that the sys-
tem complies with the fundamental requirements of the con-
struction products directive. The air/flue gas system is not
approved as part of the boiler.
The air/flue gas chimney must be designed and approved for
negative-pressure operation by the manufacturer.
The air/flue gas chimney's identification plate is marked for
operation with condensing units 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.
