Ridge Terminal
2.0 DESCRIPTION
The un-balanced ridge terminal flue system
comprises a number of the push fit socketted
concentric and single pipe components (shown
opposite), and is designed to allow air to be
taken from the roof space and the flue gases
to be discharged to atmosphere through a
suitable ridge tile terminal.
A-CLASS
Because the GulfStream
appliance the whole of the flue MUST be
installed with a continuous minimum fall of
3° back to the boiler. (50mm/metre)
Because the GulfStream A-CLASS
appliance,conventional ridge tiles and terminals
are not suitable. However special ridge tiles are
available from Redland, Marley and Sandtoft to
suit the ridge terminal supplied with this kit.
If it is proposed to use a ridge tile from any other
manufacturer, Gledhill Technical Department
should be consulted as soon as possible to allow
the necessary arrangements to be made.
It is important that the specification and
fixing of the ridge tile and terminal is checked
and confirmed as suitable before the flue is
installed.
It is also important that the flue terminal is
located as near as practical to the GulfStream
appliance and the route of the flue
A-CLASS
is checked and clear of any roof trusses or other
obstructions in the roofspace.
The roof space or other suitable compartment/
duct must be provided with adequate
ventilation openings to fresh air and be
adequately sealed from the rest of the dwelling
by means of a tight fitting trap door or similar.
WARNING :
The appliance takes it air for combustion
from the loft space.
Therefore ;
• The loft must not be used as a living
space.
• The air inlet terminal in the loft must not
be blocked.There must be at least 600mm
clear space around the air inlet terminal.
• The loft must have adequate ventilation.
Note: An equivalent 80mm single and
80/125mm concentric flue system is also
available. Please consult Gledhill Technical
Department if this is considered necessary.
