: Connection to an exhaust duct venting
the combustion products outside of the
installation area, with the combustion air
being drawn directly from this area.
: Connection to an exhaust system of the
combustion products designed to operate
with positive pressure.
: Connection by pipes with horizontal
terminal units that simultaneously intake
the combustion air and discharge the
combustion products outside through
openings that are either concentric or
close enough together to be subjected to
similar wind conditions.
: Connection by pipes with vertical terminal
units that simultaneously intake fresh air
and discharge the combustion products
outside through openings that are either
concentric or close enough together to be
subjected to similar wind conditions.
: Connection with an individual system of
which the exhaust duct for the combustion
products is installed in an exhaust pipe
that is part of the building. The appliance,
the exhaust duct and the terminal units
are certified as an assembly that cannot
be dissociated.
: Connection by two ducts to a collective
duct system serving more than one
appliance; this system of collective ducts
features two ducts connected to a
terminal unit that simultaneously intakes
fresh combustion air and discharges the
combustion products outside through
openings that are either concentric or
close enough together to be subjected to
similar wind conditions.
: Connection to separate ducts for the
supply of combustion air and for venting
the combustion products; these ducts may
end in zones with different pressure levels.
