Step 3
Lift the top edge of the baffle plate and place the
wedge shape on the boiler cross tank with the
pointed end facing up. Push the wedge down which
will push the baffle back into position. See Fig.11

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 from the appliance, when the length of
the horizontal section should not exceed 150mm
(6").
In order to minimise flue resistance and to make
sweeping easier it is recommended to use 2 x 45
bends rather than a 90

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
