INSTALLING THE APPLIANCE FOR
REAR FLUE OUTLET (Fig.28-30-31-32)
5.5.1
Use adhesive tape to attach the template to
the wall, making sure that the centre line is
vertical.
- Mark the two holes for to fix the hanging
bracket on the wall as well as the centre
of the flue duct.
- Detach the template from the wall.
- Use a 10 mm. dia drill to make the 2 holes.
Insert the plastic expansion plugs.
- Cut or core drill a 105 mm. dia hole for
inserting the flue duct.
- Locate the wall hanging braket and fix by the
two coach bolts
Fit the elbow header positioning it
towards the required direction (Fig 28).
Fig 28
5.5.4
Insert the flue assembly into the wall, being
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.28), locating
onto the fixing jig wall bracket.
5.5.6
Working above the boiler pull the flue exhaust
duct towards the boiler in order to engage tube
61 into its header.
Position flue into elbow header and push so as
to locate inner and outer flue correctly ensuring
good seal is made with o rings.
5.5.7
Fit terminal cover plate and if necessary
terminal guard.
5.5.8
Extensions kits are available to order
for flue extension of up to 7 metres total
length.(Fig.31A).
5.5.2
Make sure that the rubber Ø 60 is locate into
the flue elbow header .
5.5.3
If using horizontal flue duct and it is too long
it can be shortened .
Shoud it be necessary to cut the flue,
always cut equal amounts from both inner and
outer pipes.
Always cut the end furthest from the terminal.
cut end must de-burred.
NOTE :
Add 30mm to overall flue length to
allow for cover plate. (Fig.12 - item 127)
Extensions must be installed with the widened
end of the air intake pipe and the tapered end
of the flue pipe aimed towards the exhaust
terminal. Extensions must be joined together
with the standard terminal pipe, and inserted 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 components must be assembled and
total length measured before cutting. The straight
end of the extension connects to the boiler. The
flue output and air intake pipes fits into the boiler
header until it stops. (Fig. 31- Fig. 31A).
When cutting both inner and outer ducts of the
extension, always ensure that the reduced end
(male) of the inner and outer duct are square and
to the same length.
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 available
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 secured to wall and flue duct.
5.5.9
Each extension length extends the pipe by
approximately 1000 mm long up to a maximum
of seven 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 tapered end of the flue
pipe aimed towards the exhaust terminal.
