suction branch tube.
Precautions must be taken to avoid the black-flow of gases into
the room from the open flue of fans or other open-fire
appliances.
NOTE: Installation and connection of the fan should be done by
a qualified person in accordance with the IEE wiring regulations.
Prior to connecting the fan to power supply, it is necessary to
make sure that there is no visible faults on the rotor, case, grid
and that there are no foreign items in air flow part of the case,
which may damage rotor's blades.
