3.9 Gas connection
The connection to the gas supply must be carried out by professionally qualified personnel, registered
in accordance with current legislation and CORGI.
When connecting the boiler to the gas supply pipe, only use appropriate gas fittings in accordance
with the Gas Safety and Use Regulations..
Before installing the boiler, check the following:
■ The pipe work must have a section appropriate for the flow rates requested and the pipe lengths installed, and
must be fitted with all the safety and control devices provided for by current standards.
■ The gas supply line must be a minimum of a 22mm diameter pipe with an uninterrupted supply from meter to
boiler and comply with current standards and regulations.
■ Check the internal and external seals of the gas supply system.
■ A gas shut-off valve must be installed upstream of the appliance
■ Before starting up the boiler, make sure that the type of gas corresponds to that for which the appliance has
been set-up
(see gas type label inside the boiler).
■ The gas supply pressure must be between the values reported on the rating plate inside the appliance.
■ Prior to installation, it is good practice to ensure that there are no machining residues on the gas supply pipe.
■ Conversion of the appliance from natural gas to LPG or vice versa must be carried out by qualified personnel.
3.10 Electrical connections
The connection to the mains power supply must be carried out by professionally qualified personnel,
registered in accordance with current legislation and authorised by Radiant Bruciatori.
Always check to make sure that the appliance has an efficient earth system. This requirement is only
satisfied if it has been properly connected to an efficient earth system installed in accordance with the
requirements of current safety standards (Standard CEI 64-8 Electrical Installations). This basic safety
measure must be checked and verified.
In case of doubt, have the electrical system checked by a qualified electrician. The manufacturer will not be
held liable for any damage or injury caused as a result of an inefficient or inexistent earth system.
■
The boiler is manufactured to European standard X4D for Electrical Protection.
■ The boiler functions with an alternating current of 230 V and 50 Hz and has maximum power absorption of 180
W. The boiler should be protected by a 3 amp fuse. The connection to the mains electricity supply must be via a
single-pole switch, with at least 3 millimetres gap between open contacts, mounted upstream of the appliance.
Make sure that the positions of the live and neutral wires correspond to the wiring diagram.
■ Ensure the domestic power supply is checked by a qualified electrician to ensure that it can support the
maximum power absorption of the appliance, as indicated on the rating plate. In particular, make sure that the
cable sizes are adequate for the power absorbed by the appliance.
■ The power supply cable must not be replaced by the user. if the cable is damaged in any way, switch off the
appliance and have the cable replaced by a suitably qualified electrician.
■ When replacing the power supply cable, only use cables of the same characteristics (HO5 VV-F 3x1) with
maximum external Ø 8 mm;
When using an electrical appliance, a few fundamental rules must be observed:
Do not touch the appliance with damp or wet parts of the body or when barefoot.
Do not pull on the electric wires.
Do not leave the appliance exposed to atmospheric elements (rain, sun, etc,) unless these conditions have been
expressly provided for.
Do not allow the appliance to be used by children or anyone unfamiliar with its operation.
