Flues; Flue Pipes - Stanley Tara Boiler Installation And Operating Instructions Manual

In adverse weather conditions, down drafts may be
experienced causing smoke or fumes to spill into the
room. If this occurs shut the appliance down by
closing the air controls. If the problem persists seek
the advice of a chimney sweep.

FLUES

Flues should be vertical wherever possible and
where a bend is necessary, it should not make an
angle of more than 45
flue runs should be avoided except in the case of a
back outlet appliance, when the length of the hori-
zontal section should not exceed 150mm.
In order to minimise flue resistance and to make
sweeping easier it is recommended to use 2 x 45
bends rather than a 90
The flue termination point must be located to min-
imise any wind effects.
pressure zones and turbulence can be created by
the roof and adjacent objects. Wind effects can also
be created by natural land contours.
To minimise the wind effects, the flue termination
point should be located a minimum of 1000mm from
the roof measured vertically and 2300mm measured
horizontally. Where this termination point does not
suffice it may be necessary to extend the flue pipe
so that the termination point is above the apex. (See

FLUE PIPES

A flue pipe should only be used to connect an appli-
ance to a chimney and should not pass through any
roof space.
Flue pipes may be of any of the following materials:
(a) Cast iron as described in BS 41: 1973
(1981), or
(b) Stainless steel with a wall thickness of
at least 1mm and as described in BS
o
EN 10095:1999 Specification for
stainless and heat resisting steel
plate, sheet and strip, for Grade 316
S11, 316 S13, 316 S16, 316 S31,
316 S33, or the equivalent Euronorm
88-71 designation, or
(c) Vitreous enamelled steel complying with BS
6999: 1989.
Flue pipes with spigot and socket joints should be fit-
ted with the socket uppermost.
Clearance to combustibles must be adhered to
when fitting the flue pipe.
The appliance is suitable for continuous operation
on solid mineral fuel and intermittent operation on
wood logs.
