INSTALLATION
In the last section, the fumes are expelled
through a vertical section.
Extensions and elbows can be added to ex-
tend the kit’s length.
Maximum equivalent length “
a
+
b
” (Fig. 6.9)
of 15 metres can be achieved utilising ex-
tensions.
Each additional elbow reduces the overall
acceptable length of the flue system as fol-
lows:
For the elbow of 45° (60/100 mm) loss 0,5 m
For the elbow of 90° (60/100 mm) loss 1 m
For the elbow of 45° (60 mm) loss
0,65 m
For the elbow of 90° (60 mm) loss
0,85 m

For the electrical connection to the boiler
use electric wires which conform to the cur-
rent regulations, with flexible cord, each
core having a cross section area
not less
than 0,75 mm
2
.
• Connect the electrical supply flexible
cord coming from the fused spur isolation
switch to the power supply terminal block
of the boiler (Fig. 6.13) keeping the same
connections for the live (brown wire) and
the neutral (blue wire). External 3 A fuse or
fused plug with same current rating is rec-
ommended.
Do not connect live wires to
terminals to which the room thermostat
must be connected.
• Connect the earth wire (yellow/green).
