4.4.1 Ventilation requirements
of fireplaces
The central "aeronom WR
300/WR 400" ventilation units
may only be installed in rooms,
apartments and user units of a
comparable size, in which air-
ventilated fireplaces are
installed, if
1. a parallel operation of air-
ventilated fireplaces for liquid
or gaseous fuels and the air-
extracting equipment can be
prevented, or
2. the extraction of exhaust gas
from the air-ventilated
fireplaces is monitored by
special safety equipment. In
the case of air-ventilated
fireplaces for liquid or
gaseous fuels, the fireplace
or the ventilation system must
be switched off if the safety
device is triggered. In the
case of air-ventilated
fireplaces for solid fuels, the
ventilation system must be
switched off if the safety
device is triggered. Central
"aeronom WR 300/WR 400"
ventilation units for the
controlled ventilation and air
extraction of an apartment or
comparable living unit may
not be installed if there are
62
air-ventilated fireplaces in the
living unit that are connected
to exhaust gas systems,
which themselves have
multiple connections.
In order to permit the intended
operation of ventilation systems
equipped with the central
"aeronom WR 300/WR 400"
ventilation units, it must be
possible to shut off any
combustion air ducts or exhaust
gas ducts from air-ventilated
fireplaces.
In the case of solid fuel fire-
places, any shut-off device may
only be operated manually. It
must be possible to identify the
position of the shut-off device
from the setting of the operating
handle. This is considered to be
fulfilled if a soot blocking device
is deployed.
Only operate the ventilation
i
system at the same time as
an air-ventilated fireplace
only if using a differential
pressure control, see
Chapter 3.2.9 and 9.6.5.
Please observe the advice
i
contained in Chapter 7.2.2.
if a fan should fail.
