135° Off-set kits are available for both concentric and
twin tube.
A Pitched Roof Flashing kit and Flat Roof Flashing kit
are available for use with the vertical flue systems.
If a horizontal flue is sited less than 2 metres 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.
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.
