TIP!
2 .8 Fireplaces
The relevant applicable rules for the joint operation of fireplaces, ventilation, extraction hoods (Federal Asso-
ciation of Chimney Sweeps (ZIV)) must be observed!
General building regulation requirements
The ventilation units with heat recovery KWL can only be installed and operated in rooms with other room air-depen-
dent fireplaces if the exhaust duct is monitored by special safety devices, which switch off the ventilation unit KWL
when activated.
We recommend that you consult the responsible chimney sweep in order to accommodate your wishes before purcha-
sing an underpressure monitoring system for fireplaces.
2 .9 Protection against contact
The ventilation units are delivered with a fan protection guard as standard.
2 .10 Motor protection device
The ventilation units have an energy-saving, maintenance-free EC motor (interference-free, ball bearing-mounted)
with the highest efficiency factor., blocking protection and electronic restart.
2 .11 „Driving rain impermeability“ of the stainless steel external facia
The stainless steel external facia is a visual part and does not serve as driving rain impermeability .
The installation of wall installation sleeve through the outer facade has to be carried out on site driving rain-
proof by appropriate measures!
2 .12 Limits of use stainless steel
Stainless steel 1 .4301 can change colour slightly due to air pollution!
Regular cleaning reduces the risk of discolouring .
When used in cities and industrial areas with strong air pollution this stainless steel is endangered by corrosion to a
certain extent.
In environments with strong air pollution and in coastal areas with a high salt concentration in the air, this stainless
steel is not suitable without additional protective lacquering (acrylic clear lacquer).
