8.3.2 Air supply and flue gas exhaust in a room sealed installation
A ventilation cover is integrated into the condensing gas system boilers.
This cover houses a number of components, such as the burner and the
heat exchanger. Since this ventilation cover is part of the air supply
system, it is vital that it is always installed correctly.
To ensure optimal operation, the appliances must be connected to a
Worcester horizontal or vertical flue terminal. These terminals have been
developed specifically for Worcester condensing gas boilers and have
been comprehensively tested for trouble free operation when correctly
installed.
