Publication No. 5102977 10
• Where a horizontal flue is sited less than 2m
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 (Sales Code:
PTERMGUARDEF), 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.
