Installation
6.5.1. Drill the wall and plug using those supplied with the con -
nections kit, position the br acket and secure with the w all
bolts supplied. Note: It is highly recommended that a spir-
it level be used to position the appliance to ensure that it is
perfectly level.
6.5.2. Position the appliance on the hanging bracket and connect
the isolating valves supplied in the connection kit as shown
on the w all template (see also Sections 6.7 Gas
Connections, 6.8 Water Connections & F
6.6
Electrical Connection
For safety purposes, have a competent person carefully chec k
the electrical system in the property, as the manufacturer will not
be held liable for damage caused by the failure to earth the appli-
ance properly or by anomalies in the supply of power. Make sure
that the residential electr ical system is adequate f or the maxi -
mum power absorbed by the unit, which is indicated on the rating
plate. In addition, check that the section of cabling is appropriate
for the power absorbed by the boiler.
The boiler operates with alter nating current, as indicated in the
Technical Information table in Section 13, where the maxim um
absorbed power is also indicated. Make sure that the connections
for the neutral and live wires correspond to the indications in the
diagram. The appliance electrical connections are situated on the
reverse of the control panel.

In the event that the power supply cord must be changed, replace
it with one with the same specifications .
Note: The diagrams for the electrical system are indicated in sec-
tion 6.13.
Warning, this appliance must be earthed.
External wiring to the appliance must be carried out by a compe-
tent person and be in accordance with the current I.E.E.
Regulations and applicable local regulations.
The appliance is supplied with a fly-lead already connected, this
must be connected to a 240v supply fused at 3A and m ust facili-
tate complete electrical isolation of the appliance, by the use of a
fused double pole isolator having a contact separation of at least
3 mm in all poles or alter natively, by means of a 3 A fused three
pin plug and unswitched shuttered socket outlet both complying
with BS 1363.
The point of connection to the Electr icity supply must be readily
accessible and adjacent to the appliance unless the appliance is
installed in a bathroom when this must be sited outside the bath-
room (see section 6.2).
Should external controls be required, the design of the e xternal
electrical circuits should be under taken by a competent person,
see section 6.12 for further information.
6.7
The local gas region contr actor connects the gas meter to the
service pipe.
If the gas supply f or the boiler ser ves other appliances ensure
that an adequate supply is a vailable both to the boiler and the
other appliances when they are in use at the same time .
Pipe work must be of an adequate siz e. Pipes of a smaller siz e
than the boiler inlet connection should not be used.

Pipe Work:
Copper tubing to BS EN 1057:1996 is recommended f or water
pipes. Jointing should be either with capillar y soldered or com-
pression fittings.
Where possible pipes should have a gradient to ensure air is car-
ried naturally to air release points and w ater flows naturally to
drain taps.
The appliance has a built-in automatic air release valve, however
it should be ensured as f ar as possible that the appliance heat
exchanger is not a natural collecting point for air.
Except where providing useful heat, pipes should be insulated to
prevent heat loss and avoid freezing.
Particular attention should be paid to pipes passing through ven-
tilated spaces in roofs and under floors .
By-pass:
The appliance includes an automatic b y-pass valve, which pro-
tects the main heat e xchanger in case of reduced or interr upted
water circulation through the heating system, due to the closing
of thermostatic valves or radiators.
