ATTENTION
WARNING
IMPORTANT ☞
Compact ceiling-mounted units KWL EC 220/340 D
The KWL unit must not be operated at the same time as solid fuel fireplaces and not in residential units
with room air-dependent fireplaces, which are connected to multiple exhaust systems.
Any existing combustion air ducts and exhaust systems for solid fuel fireplaces must be capable of being
shut off for the proper operation of the ventilation system established with a ventilation unit with heat
recovery.
We recommend that you consult the responsible chimney sweep in order to accommodate your wishes
TIP!
before purchasing an underpressure monitoring system for fireplaces.
Monitoring systems are always integrated in the unit supply cable! (see circuit diagram SS-1043)
ATTENTION DANGER TO LIFE! The use of the external contact (function 1; enable/disable unit) of
