5.6.1 Practical connection examples: combustion air
and convection
Situation 1 - Recommended situation
The combustion air is connected directly to the fireplace from
outside. The outside air is not in contact with the room in
which the fireplace is installed or with the chimney breast. The
convection system is also connected directly to the fireplace.
There are no open connections between the interior of the
chimney breast and the room in which the fireplace is installed.
Situation 2
The combustion air is connected directly to the fireplace from
outside. The outside air is not in contact with the room the
fireplace is installed in or with the chimney breast. The convection
system is only in contact to the room in which the fireplace is
installed.
Situation 3
The combustion air cannot be connected directly to the fireplace;
this air must be taken from the room the fireplace is installed
in. This mainly occurs in an existing situation, in which the
combustion air can only be taken from the room the appliance
is in. The convection system must then be physically separated
from the combustion air; connect the lower and upper convection
gratings directly to the appliance. The combustion air reaches the
fireplace through extra openings in the chimney breast. see the
Technical data (Table 4) for the throughput of these openings.
The convection connections at the top of the fireplace must be
connected at all times.
