BOILER OPERATION AND ADJUSTMENT PROCEDURES FOR USERS
Before turning on the boiler read the following warnings carefully .
Make sure that the warranty booklet carries the stamp of the CORGI registered technician (you can check this by contacting
corgi on 01256.372200) responsible for installing the boiler. Installation, starting up for the first time, adjustments and
maintenance operations must all be carried out solely by qualified technicians. Incorrect installation may cause damage to
persons, animals or property for which the manufacturer cannot be held liable.
WARNING!
⇒
Do not start the boiler unless you are sure it has been thoroughly tested by an authorised technician.
⇒
Check that the regulations regarding air intakes and ventilation of the room where the boiler is installed have been
fully complied with (see installation instructions p.2).

The anti-freeze system will come into operation only if the boiler is in the «ON» position (with selector switch 1 in
fig. 1 turned to the summer or winter position) and the gas supply turned on. The manufacturer can accept no
responsibility for damage to the boiler caused by lack of observation of these requirements.
⇒
If the boiler should freeze up, under no circumstances attempt to turn it on but call the RADIANT HELP LINE
immediately.
