Depending on site conditions it may be prefer-
able to install the terminal assembly prior to fit-
ting the twin flue pipes.
Fit the appropriate flashing plate to the roof and
insert the vertical flue terminal through the flash-
ing plate from the outside, ensuring that the col-
lar on the flue terminal fits over the flashing.
Push-fit the twin flue pipes onto the concentric
to twin converter ensuring that the exhaust pipe
connects to the exhaust connection on the con-
centric to twin converter.
If necessary cut the plain ends (male) of the twin
flue pipes to allow connection to the concentric
to twin converter.
NOTE
●
Before cutting twin flue pipes ensure allow-
ances have been made for connection onto the
previous piece and onto the concentric to twin
converter. The last twin flue pipes must be
pushed 50mm onto the male spigots of the con-
centric to twin converter.
●
You must ensure that the entire flue system is
properly supported and connected.
●
Ensure that any horizontal sections of pipe have
a minimum 1º fall towards the appliance (17mm
per 1000mm).

CONNECTING THE GAS AND WATER
The appliance is supplied with an accessory pack
that includes service valves.
The service valves are of the compression type.
The accessory pack contains sealing washers’ etc,
for use with the service valves. When connecting
pipe work to the valves, tighten the compression
end first then insert the sealing washers before
tightening the valve to the appliance.
NOTE
It will be necessary to hold the valve with one
spanner whilst tightening with another
4.6.1
GAS (fig. 6 & 14)
The appliance is supplied with a 15mm service
valve, connect a 15mm pipe to the inlet of the
valve and tighten both nuts.
NOTE
It will be necessary to calculate the diameter of
the gas supply pipe to ensure the appliance has
an adequate supply of gas.
4.6.2
FLOW & RETURN (fig. 6 & 14)
The appliance is supplied with 22mm service
valves for the flow and return connections, con-
nect a 22mm pipe to the inlet of each valve and
tighten both nuts.
NOTE
Depending on system requirements, it may nec-
essary to increase the size of the flow & return
pipe work after the service valve connections.
4.6.3
COLD WATER INLET (fig. 6 & 14)
The appliance is supplied with a 15mm stopcock,
connect a 15mm pipe to the inlet of the stopcock
and tighten both nuts.
4.6.4
HOT WATER OUTLET (fig. 6 & 14)
The appliance is supplied with a 15mm outlet
connection, connect a 15mm pipe to the outlet
connection and tighten both nuts.
4.6.5
SAFETY VALVE (fig. 6 & 14)
Connect the safety valve connection pipe to the
safety valve outlet and tighten. The discharge
pipe must have a continuous fall away from the
appliance to outside and allow any water to drain
away thereby eliminating the possibility of freez-
ing. The discharge pipe must terminate in a
position where any water - possibly boiling -
discharges safely without causing damage or
injury, but is still visible.
4.6.6
CONDENSE PIPE (fig. 6 & 14)
During normal operation the boiler produces con-
dense which is collected in a trap located in the
lower part of the boiler. A flexible pipe (condense
outlet pipe) is connected to the outlet of the trap.
The flexible pipe must be connected to a plastic
waste pipe only. The plastic waste pipe must
have a minimum of a 3º fall towards the drain. Any
external run of pipe should be insulated to pre-
vent the risk of freezing.
CONNECTING THE CONDENSATE OUTLET
Gently pull the condense outlet pipe down from
its location inside the boiler until approximately it
protrudes from the underside of the boiler. Con-
nect a suitable plastic (not copper) pipe (no less
than 21mm diameter) to the outlet pipe and
ensure it discharges in accordance with local
building regulations or other rules in force.
4.7
ELECTRICAL CONNECTIONS
The boiler is supplied with a 2-metre fly-lead. This
lead can be used for connection to the electrical
supply. Connect the fly-lead to a fused plug or
fused isolator in the following way:
●
brown wire to LIVE supply
●
blue wire to NEUTRAL supply
●
green/yellow to EARTH connection.
Insert the supplied 3-AMP fuse into the fused
isolator or fused plug.
Should the fly-lead be unsuitable, refer to 4.7.3
for details on how to connect the electrical supply
directly to the boiler.
The electrical supply must be as specified in
section 3/3A. A qualified electrician should con-
nect the appliance to the electrical supply. If
controls - external to the appliance - are required,
a competent person must undertake the design
of any external electrical circuits, please refer to
section 8 for detailed instructions. ANY EXTER-
NAL CONTROL OR WIRING MUST BE SERVED
