Exhaust vent
Exhaust vent for collection and upstream direction of escaping gases

Chimney with fan
Exhaust gases are better removed from the furnace and discharged. The B500 - P580 controllers can be used to switch the chimney with fan automatically (not for models L(T) 15.., L 1/12, LE 1/11, LE 2/11).*

Catalytic converter with fan
Organic components are catalytically cleaned at about 600 °C, broken into carbon dioxide and water vapour. Irritating odors are thus largely eliminated. The B500 - P580 controllers can be used to switch the catalytic converter automatically (not for models L(T) 9/14, L(T) 15.., L 1/12, LE 1/11, LE 2/11).*

* Note: If other controller types are used an adapter cable for connection to mains supply has to be ordered separately. The device will be activated by plugging in the socket.
