FITTING INSTRUCTIONS (cont.)
WATER SYSTEM
Connect the flow and return pipework from the
radiator(s) into the corresponding fittings on the boiler
manifold. Ensure all fittings are made water-tight.
Notes:
a)
The pressure relief valve must be piped to a
permanent drain-off on the outside of the
building. The drain must not discharge above
an entrance, window, or any public access
area. It should be clear of any electrical
fittings, and positioned so that any discharge
can be clearly seen. The terminating point of
the drain-off should be bent down at an angle
of 90°.
b)
It is recommended that isolation valves are
fitted to the pipework. A bypass, as shown in
Fig. 4
, must be fitted if TRVs are used on the
radiators.
c)
The flow and return connections are made to
the boiler by 2 x 15mm compression fittings.
ELECTRICITY SUPPLY
First isolating the electricity, pass the electrical supply
cables and any external control cables through the
cable strain reliefs in the base of the boiler, and wire
securely into the terminal block. The terminal block is
located within the casings at the top left-hand side of
the boiler.
Notes:
a)
This appliance must be earthed.
b)
It is recommended the boiler is fitted with an
external control, such as a room thermostat
or programmer.
c)
If the water in the system is to be subject to
freezing conditions during the pipework run,
the appliance should be fitted with a frost
thermostat. This will activate the boiler should
the temperature fall to a level which could
damage the installation.
d)
Incoming mains and controls cables should
not be routed close to heating pipes.
e)
The diagrams opposite are for reference only.
Refer to manufacturer's instructions for
specific fitting instructions for the room
thermostat or programmer.
f)
It is recommended that the boiler is wired via
a 13 amp RCD plug or switched fused spur.
g)
Remove the link wire between terminals 3 &
5 when fitting any external controls.

Important Note:
Before installation, please ensure that the supply
voltage to the appliance is above 207v. If the voltage
drops below this level, a temporary boiler malfunction
may result.
