Carefully remove the packing from
around
the boiler.
Fit the water flow
and
return fittings into the required positions
on
the boiler.
If
only one flow

one return connection is required, then they should preferably
be
positioned on opposite sides of the boiler.
Place
the
boiler
in
the
required installation position
and
remove
the
top
panel,
by
lifting
it
upward,
and
the
lower front panel
by

and
remove
the
4 screws located
in
the balanced flue outlet
on
the boiler.
Remove
the
access plate from
the
end
of the balanced flue duct,
and
locate the duct over the
four fixing holes
on
the outlet
of
the boiler. Ensure
that
the gasket is correctly fitted between the
two
faces.
The

then
be placed in position, face
down
again
with
a gasket in place.
The four fasteners should
be
tightened,
and
the exhaust tube slid into the duct
and
inserted into
the spigot. Joints should then
be
sealed
with
fire cement prior to fitting the access cover.
The
wind
cowl should
then
be
fitted over the
end
of the duct, ensuring the
gap
between
the
dish
and
the extension tube
on
the exhaust is not more
than
40 mm.
Locate
the
terminal
guard
basket over the
wind
cowl
and
