2.2 REGULATIONS FOR THE OPERATION
WITH FIREPLACES
Local requirements must be taken into con-
sideration by compliance with correspond-
ing standards, laws and directives.
The central ventilation units
with heat recovery may only
be installed in rooms, flats or
utilisation units of a comparable size in
which fireplaces dependent on room air are
installed, if:
•
simultaneous operation of room air-de-
pendent fireplaces and the air extraction
unit is prevented by safety devices, or
•
the flue gas evacuation of the room
air-dependent fireplace is monitored by
special safety devices.
-
In the case of room-air dependent
fireplaces for liquid or gaseous fuels,
activation of the safety device must
lead to the switch-o of the fireplace or
ventilation unit.
-
In the case of room-air dependent
fireplaces for solid fuels, activation of the
safety device must lead to the switch-o
of the ventilation unit.
The central ventilation units for the con-
trolled aeration and ventilation of a flat or a
comparable living unit must not be installed
if room air-dependent fireplaces in the
living unit are connected to exhaust gas
systems, which themselves have multiple
connections.
Shut-o device
Normal operation of the ventilation sys-
tems established by means of the central
ventilation units requires the possibility of
shutting potentially available combustion
air ducts as well as exhaust gas systems
o from room air-dependent fireplaces.
In the case of exhaust gas systems of
fireplaces for solid fuels, it must be ensured
that the shut-o device can only be oper-
ated manually. The position of the shut-o
device must be identifiable by the setting
of the operating handle. This specification
is considered as complied with if a shut-o
device against soot is used.
Fire protection requirements
With regard to the fire protection instal-
lation regulations for the set-up of the
ventilation unit, the provisions of national
law, in particular the building regulation
concerning the fire protection requirements
with regard to ventilation systems in the
relevant latest version must be observed.
Due to the heavy load as well as the irreg-
ular operation, the extract air of a kitchen
extractor hood must not be integrated into
the dwelling's ventilation system. Extract
air from such extractor hoods must be con-
ducted separately by means of an exhaust
air pipe over the roof. The supply air must
be provided for separately (e.g. by window
ventilation). If an extractor hood without
the separate provision of supply air is op-
erated, the balance of the air volume in the
dwelling is no longer kept and the proper
function of the dwelling's ventilation system
is no longer ensured (odour diversion, etc.).
Another option is to operate the extractor
hood in recirculation mode.
