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 collar
on the flue terminal fits over the flashing.
The fixing holes for the wall-mounting bracket
should now be drilled and plugged, an appropri-
ate type and quantity of fixing should be used to
ensure that the bracket is mounted securely.
Once the bracket has been secured to the wall,
mount the appliance onto the bracket.
IMPORTANT
The vertical flue terminal cannot be cut; therefore
it may be necessary to adjust the height of the
appliance to suit or use a suitable extension.
Connect the vertical flue assembly to the boiler flue
spigot using the 60mm & 100mm clips, gaskets &
screws (supplied), ensuring the correct seal is
made. The flue support bracket (supplied with the
vertical flue kit) can now be fitted.
If the vertical flue requires extension/s or addi-
tional bend/s, connect the required number of
flue extensions or bends (up to the maximum
equivalent flue length) between the boiler and
vertical flue assembly (see fig. 8).
Ensure that any horizontal sections of the flue
system have a minimum 1º fall back to the boiler
(17mm per 1000mm).
NOTE
When cutting an extension to the required length,
you must ensure that the excess is cut from the
plain end of the extension (see fig. 8). Remove
any burrs, and check that any seals are located
properly. You must ensure that the entire flue
system is properly supported and connected.

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 & 10)
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 & 10)
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 & 10)
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 & 10)
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 & 10)
Connect the safety valve 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 freezing. The dis-
charge 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 & 10)
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 prevent
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.
