To avoid a fire hazard due to grease in the grease filter, a distance of 400
n
mm [15.75 inch] must be maintained between the flue gas pipes of the de-
vice and the grease filters of the extractor hood/ventilation ceiling.
An up-current socket is not required.

The flue gases must be discharged into the open air via kitchen ventilation
n
systems. The flue gases from the gas device with type A flue gas connection
are first discharged into the room and promptly discharged via kitchen ven-
tilation systems.
By monitoring the flue gas discharge, it must be ensured that the gas supply
n
to the burners is only released if extraction is ensured.
