5.5.4 Insert the flue assembly into the wall, being
Fig. 35
careful to make sure that the outer air duct
comes flush to the inner surface of the wall.
5.5.5 Lift the boiler on to the wall (Fig. 34), locat-
ing onto the top coach bolts. Fit the two
lower coach bolts and tighten all four
securing bolts.
5.5.6 Working above the boiler pull the flue
exhaust duct towards the boiler in order to
engage tube 61 into its header 57A
(Fig. 31).
Position flue into elbow header and push so
as to locate inner and outer flue correctly.

Fit terminal cover plate if required.
Extension kits are available on order.
5.5.11
Each extension length extends the pipe by
approximately 1000 mm long up to a maxi-
mum of two extensions.
Pipeline length can be established using
the instructions in section 5.5 for rear flue
outlets and section 5.7 for side flue outlets.
Extensions must be installed with the
widened end of the air intake pipe and the ta-
pered end of the flue pipe aimed towards the
exhaust terminal. Extensions must be joined
together with the standard terminal pipe, in-
serted in each other as far as they can go.
If an extension must be shortened, this
must be done from the straight end, and
not from the widened or tapered end. To
measure the pipeline properly all compo-
nents must be assembled and total length
measured before cutting. The straight end
of the extension connects to the boiler. The
flue output pipe fits into the boiler header
until it stops. The air intake pipe should be
located approximately 2 mm from the boiler
header (Fig. 31).
When cutting both inner and outer ducts of
the extension, always ensure that the
reduced end (male) of the inner duct is
longer than the outer duct.
All joints must be sealed with the rubber
seals supplied.
It is important to put the centering spacer,
supplied with the unit, inside between the
two pipes, from the side opposite the
extension’s straight end.
NOTE: a suitable support bracket is availa-
ble from Ravenheat Manufacturing and
should be used to support flue length at
least every 1.8 metre preferably at each
joint this bracket should be rigidly secured
to wall and flue duct.
IN LINE FLUE BEND
Measure the distance between the flue
bends or the flue/terminal assembly. The
measurement should be taken from the
outer edge of the flue and bend (Fig. 398).
IMPORTANT: in line flue bend - 750 mm
must be deducted from overall length for
each 90
o
bend. Obtuse flue bend - 375 mm
must be deducted from overall length for
each 135” bend (Fig. 39 B).
