INSTALLATIoN

Appliance description

- 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
Note
Differential pressure switches that use the pressure dif-
ferential between the outdoor air pressure and the pres-
sure in the combustion equipment installation room as a
response criterion are not suitable.
Note
We recommend installing and regularly maintaining a
carbon monoxide detector in accordance with EN 50291
for operation of any combustion equipment.
2.4.2 Commissioning
When commissioning the ventilation unit, it is important to check
and document in the commissioning log that combustion exhaust
gases are not penetrating the dwelling in a quantity 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 acceptance pro-
cedure.
2.4.3 Maintenance
Regular maintenance of the combustion equipment is prescribed.
Maintenance includes checking the exhaust gas extraction system,
the free pipe cross-sections and the safety equipment. The rele-
vant qualified contractor responsible must prove that there is a
sufficient flow of combustion air.
