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 without 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 size 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 should be fitted on the boiler gas inlet. Please
wait 10 minutes when lighting from cold before checking the gas rate. Gas pressures should be checked after
the boiler has operated for 10 minutes to ensure thermal equilibrium.
The connecting kits shown in fig. 7 are supplied as standard.
2.5 Electrical Connections
The unit must be installed in conformity with current national and local regulations.
Connection to the electrical supply
The boiler must be connected to a single-phase, 230 Volt-50 Hz electric supply.
The unit’s electrical safety is only guaranteed when correctly connected to an efficient earthing system installed
according to current safety standards. Have the integrity of the earthing system checked by professionally
qualified personnel. 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 used by the unit, as specified
on the boiler dataplate, in particular ensuring that the cross section of the system’s cables is suitable for the
power used by the unit.
The boiler is prewired and provided with a cable for connection to the electricity supply. The connections to the
supply must be made with a permanent connection and equipped with a double pole switch whose 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 respect
the polarities (LIVE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) in making connections to
the electrical supply.
The user must never change the unit’s 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 solely
“HAR
H05 VV-F”
3x0.75 mm
2
cable with a maximum outside diameter of 8 mm.
5 Core cable must not be used to replace the existing 3 core!
