Flue Terminal Location
Installation Requirements
•
Where a horizontal flue is sited less than
2 m above a balcony, above ground, or
above a flat roof to which people have
access, a suitable terminal guard must be
fitted. This serves two purposes, to protect
the terminal against damage or
interference and to protect passers-by. A
terminal guard is available (Part No.
205792), this should be fitted centrally
about the terminal.
Note: Where a flue terminal is installed
less than 1 metre from a plastic, or painted
gutter, or 500 mm from painted eaves, an
aluminium shield 1 metre long, should be
fitted to the underside of the gutter or
painted surface. A suitable wall plate
should be fitted to the painted wall surface
of a mobile home.
•
IMPORTANT: It is absolutely
ESSENTIAL, to ensure that products of
combustion discharging from the terminal
cannot re-enter the building, or any other
adjacent building, through ventilators,
windows, doors, natural air infiltration, or
forced ventilation/air conditioning. If
products of combustion are found to be re-
entering any building, the appliance MUST
be turned OFF IMMEDIATELY.
