9.3 Heating safety valve (3 bar RED) and
domestic safety valve (10 bar BLUE)
discharge, refer to diagrams 9.4.
Two short discharge pipes and washers are supplied in the
fittings pack, fit these to the heating safety valve 3 bar and the
domestic water safety valve 10 bar. The discharge must be

visible position outside the building, facing downward preferably
over a drain.
IMPORTANT NOTE:
To facilitate servicing of the appliance,
the discharge pipe MUST ONLY be extended using the
compression fittings supplied.
The pipes must have a continuous fall and be routed to a
position so that any discharge of water, possibly boiling or
steam, cannot create any danger to persons, damage to property
or external electrical components and wiring. Tighten all pipe
connection joints.

The filling loop extension knob is supplied in the discharge
safety valve pipe connection pack. Fit to the filling device on/off

9 Boiler Installation
10 Horizontal Rear Flue Installation
The
Horizontal Rear flue - kit No A2009700 is
suitable for installations that require a flue
length from 190mm minimum to 667mm
maximum, without extensions, measurement
taken from the rear of the boiler to outside
wall face, see diagram 10.4 (3.).
If a longer flue length is required a 1metre
pipe extension can be used to give a
maximum flue length of no more than 1500,
measurement taken from the rear of the boiler
to outside wall face.
10.1 Horizontal Rear Flue kit of parts, refer to
diagram 10.1.
10.2 Cutting Rear Flue, refer to diagram 10.2.
Important Notes
: After cutting ensure that there are no burrs.
10.3 Installation of Rear Flue assembly
• Fit rubber sealing collar
(C)
into groove at the outer end of the
flue assembly
(A)
and
(B), see diagram 10.3.
• Fit flue assembly
with attached rubber sealing collar into wall

assembly inwards to bring rubber sealing collar hard up against
external wall. The oposite end must exit the inner wall face by
40mm.
see diagram 10.4. (1.)
• Fit the plastic internal flange
(G)
over the flue, push along the
pipe until engaged against internal wall,
see diagram 10.4. (2.)
• Remove the backing from one of the wrap around self
adhesive seals
(D)
and carefully fit seal around the flue against
the internal flange at the inner wall face, trim to fit,
see diagram
10.4. (2.)
• Remove the backing from the other wrap around self adhesive
seal
(D)
and carefully fit seal around the front end of the flue that
is extending
40mm
from the inner wall face, trim to fit,
see
diagram 10.4. (2.)
• Fit the ‘O’ ring
(H)
into the adaptor
(F),
apply a small amount
of silicone grease to the ‘O’ ring when fitting.
• Ease the adaptor
(F)
over the seals,
see diagrams 10.4 (3.)
and 10.5.
•
Fit the adaptor sealing gasket
(G)
to the adaptor.
Preparing the boiler
• Lift the boiler up and engage boiler upper part onto the hanging
bracket.
• Fit the washers between the boiler pipes and the inlet and
outlet fittings on the fixing jig and connect the various couplings
between the boiler and jig.
Now the boiler is on the wall, slide forward the adaptor about
20mm. secure it on to the back of the boiler with the two screws
