NOTE:
On the basis of REGULATION
COMMISSION of 2nd August 2013:
"This natural draught boiler is intended to be connected only to
a flue shared between multiple dwellings in existing buildings
that evacuates the residues of combustion to the outside of the
room containing the boiler. It draws the combustion air directly
from the room and incorporates a draught diverter. Due to
lower efficiency, any other use of this boiler shall be avoided
and would result in higher energy consumption and higher
operating costs."
