2.4 Connection to the gas system

If necessary the local Gas supplier should be consulted, at the installation planning stage, in order to
establish the availability of an adequate supply of gas.
An existing service pipe must not be used whitout prior consultation with the local Gas supplier.
A gas meter can only be connected by the Local Gas supplier, or by a Local Gas suppliers Contractor.
Installation pipes should be fitted in accordance with BS6891.
Appliance inlet working pressure must be 20 mbar MINIMUM, for NG and 37 mbar minimum for pro-
pane.
Do not use pipes of a smaller diameter than the combination boiler inlet gas isolation valve (22 mm).
The complete installation must be tested for gas soundness and purged as described in BS6891.
All pipework must be adquately supported. An isolating gas valve is provided and must be fitted
on the boiler gas inlet. Please wait 10 minutes when lighting from cold before checking the gas
rate, this will ensure thermal equilibrium.

2.5 Electrical Connections

The unit must be installed in conformity with current national and local regulations inc 16th Edition &
B.S 7671 .
Connection to the electrical supply.
The boiler must be connected to a single-phase, 230 Volt-50 Hz electrical supply.
The unit's electrical safety is only guaranteed when correctly connected to an efficient earthing
system installed according to current safety standards and checked by a professionally qualified
person . The manufacturer is not responsible for any damage caused by failure to earth the system.
Also make sure that the electrical system is adequate for the maximum power absorbed by the
unit, as specified on the boiler dataplate, in particular ensuring that the crossectional area of the
electrical cables are suitable for the power absorbed by the unit .
The boiler is prewired and provided with a cable for connection to the electrical supply The prewired
cable must be connected to the supply with a permanent connection and equipped with a double pole
switch which contacts have a minimum opening of at least 3 mm, and fused at max. 3A between the
boiler and the line. It is important to check the polarities (LIVE: brown wire / NEUTRAL: blue wire /
EARTH: yellow-green wire) and ensure they are correctly connected to the corresponding terminals on
the electrical supply .
The user must never change the boilers power cable. If the cable gets damaged, switch off the unit
and have it changed only by professionally qualified personnel. If changing the electric power cable,
use only "HAR H05 VV-F" 3x0.75 mm
5 Core cable must not be used to replace the existing 3 core!
