The boiler has been designed for use with a open-vented central heating system, and comes
fully tested and assembled. The boiler is easily mounted on any internal wall and can be
installed with either a horizontal or vertical RSF (room sealed fan assisted) flue. The boiler uses
a standard flue system (100 mm or 125 mm outside diameter). Flue extensions and additional
bends and elbows are available for the flue system to increase the flexibility. If desired, an
inhibitor may be used in the system. Guidance on the use of inhibitors is contained in these
instructions. The boiler has a built in diagnostic system which indicates the operational status of
the boiler. This feature provides key information to aid commissioning and fault finding. The data
badge is fitted to the combustion chamber cover of the boiler. See text of General Requirements
for installation requirements or notes.
The Valliant ecoTEC plus boiler is a state-of-the-art appliance which has been constructed in
