7.3.1 Planning safety measures
Together with the relevant authorities, engineers plan the safe-
ty measures that are required for simultaneous operation of a
ventilation unit and combustion equipment.
Alternate operation
Alternate operation means that when commissioning the
combustion equipment, the mechanical ventilation system is
switched off or cannot be started. Alternate operation must be
ensured by appropriate measures, e.g. automatically enforced
shutdown of the ventilation unit.
Simultaneous operation
For simultaneous operation of combustion equipment and a
mechanical ventilation system, we recommend choosing ap-
proved room-sealed combustion equipment (in Germany, with
dIBt approval).
If open-flue combustion equipment is operated in the dwell-
ing at the same time as a ventilation unit, combustion exhaust
gases must be prevented from penetrating the home due to
negative pressure in the room.
The ventilation unit may only be operated in combination with
intrinsically safe combustion equipment. This combustion
equipment has, for example, a draught hood or an exhaust gas
monitor and is approved for operation in conjunction with ven-
tilation units. Alternatively, external, tested safety equipment
can be connected to monitor the operation of the combustion
equipment. For example, you can install differential pressure
monitoring to monitor the chimney draught and to switch off
the ventilation unit in the event of a fault.
The equipment for differential pressure monitoring must fulfil
the following requirements:
- Monitoring of the differential pressure between the con-
nection piece to the chimney and the combustion equip-
ment installation room
- Possibility of matching the shutdown value for the differ-
ential pressure to the minimum draught requirement for
the combustion equipment
- Floating contact to switch off the ventilation function
- optional connection of a temperature capturing device so
that differential pressure monitoring is only enabled when
the combustion equipment is in operation and so that un-
wanted shutdowns due to environmental influences can
be prevented
Notice
differential pressure switches that use the pressure
differential between the outdoor air pressure and the
pressure in the combustion equipment installation
room as a response criterion are not suitable.
Notice
we recommend installing and regularly maintain-
ing a carbon monoxide detector in accordance with
eN 50291 for operation of any combustion equipment.

7.3.2 Commissioning
when commissioning the ventilation unit, it is important to
check and document in the commissioning log that combus-
tion exhaust gases are not penetrating the dwelling in a quan-
tity that is harmful to health.
Commissioning in Germany
Acceptance is carried out by the local flue gas inspector.
Commissioning outside Germany
Acceptance must be carried out by a specialist. In case of
doubt, you must involve an independent expert in the accept-
ance procedure.
7.3.3 Maintenance
regular maintenance of the combustion equipment is pre-
scribed. Maintenance includes checking the exhaust gas ex-
traction system, the free pipe cross-sections and the safety
equipment. The qualified contractor responsible must prove
that there is a sufficient flow of combustion air.
