Reco-Boxx ZXR / ZXA / Flat – Operation and maintenance instructions [03/ 2021]
Risk of death when operating with air-ventilat-
ed fireplaces.
Ensure sufficient supply air intake
during operation with air-ventilated fireplaces.
Note maximum permissible pressure difference
per residential unit. The consent of a professional
chimney sweep is needed in all cases. Ventilation
units may only be installed in rooms, apartments
or housing units of a comparable size, in which
air-ventilated fireplaces are installed if:
• a parallel operation of air-ventilated fireplaces
for liquid or gaseous fuels and the air-extract-
ing equipment can be prevented via safety
devices, or
• the extraction of exhaust gas from the air-ven-
tilated fireplaces is monitored by a special
safety device. In the case of air-ventilated fire-
places 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. In order to permit
the intended operation of ventilation systems
equipped with the central ventilation units with
heat recovery, it must be possible to shut off
any combustion air ducts or exhaust gas ducts
from air-ventilated fireplaces. For exhaust gas
ducts of fireplaces for solid fuels, the shut-off
device may only be operated by hand. 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.
