The air which is drawn in is cleaned by the grease filters and conveyed to the exterior by a pipe system.
Note: The exhaust air must not be conveyed into a functioning smoke or exhaust gas flue or into a shaft which is used to ventilate installation rooms which contain heat-producing appliances.
Before conveying the exhaust air into a non-functioning smoke or exhaust gas flue, obtain the consent of the heating engineer responsible.
If the exhaust air is conveyed through the outer wall, a telescopic wall box should be used.
