WARNING
Risk of death
Risk of poisoning from flue gases that are drawn
back in. The exhaust air must not be conveyed
into a functioning smoke or exhaust gas flue or
into a shaft that is used to ventilate installation
rooms that contain heating appliances. If the
exhaust air is to be conveyed into a non-
functioning smoke or exhaust gas flue, you must
obtain the consent of the heating engineer
responsible.

As a result of long rough exhaust air pipes, many
pipe bends or pipe diameters that are smaller than
6" (150 mm), the optimum extraction performance is
not achieved and fan noise is increased.
