Installation and Servicing
SECTION 2 - INSTALLATION
2.19 REPLACING PRE-FITTED MAINS CABLE
If it is necessary to use an alternative mains cable to the one pre-fitted
then use the following guide.
Replacement wiring should comply with notes in Section 2.18 and be
caried out by a qualified person to avoid a hazard.
1. Isolate the mains supply to the boiler.
2.
Remove the front panel. Refer to Section 3.2.
3. Swing the control box down into the service position, unclip and swing
back the installer wiring cover to latch into the retaining clips. Refer to
Section 3.8.
4.
Unplug the mains connector and release the cable from strain relief.
5. Unscrew the L N & E connections & remove wires from connector.
6.
Remove the mains cable by pulling back through the grommet .
7. Route the replacement cable through the grommet and re-fit in
reverse order.
8. Close the installer wiring cover ensuring that it is located correctly and
that the cable is retained into the strain relief as shown.
9. Swing the control box back up into the operating position and re-fit
the front panel ensuring a good seal is made.
NOTE. When making the mains electrical connections to the boiler it
is important that the wires are prepared in such a way that the earth
conductor is longer than the current carrying conductors, such that if the
cord anchorage should slip, the current carrying conductors become taut
before the earthing conductor.

2.20 EXTERNAL ELECTRICAL CONTROLS
Wiring External to the Boiler
The fuse rating should be 3A.
Wiring external to the boiler MUST be in
accordance with the current I.E.E. (BS.7671)
Wiring Regulations and any local regulations.
Frost Protection
If parts of the pipework run outside the house or if
the boiler will be left off for more than a day or so
then a frost thermostat should be wired into the
system.
The frost thermostat should be sited in a cold
place but where it can sense heat from the
system.
Note
. If the boiler is installed in a garage it may
be necessary to fit a pipe thermostat, preferably
on the return pipework.
