BOILER OPERATION AND ADJUSTMENT PROCEDURES FOR USER
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.
⇒ The anti-freeze system will come into operation only if the ON/OFF switch 1 (see fig.1) is ON 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.

Turning on procedure for electronic ignition
§ turn on the gas cock situated under the boiler grill;
§ set the ON/OFF button 1 (see fig.1) to ON position ;
§ make sure that no flashing value is on the display (14); if value 04 is flashing and no.8 light is ON it means water
deficiency in the system: open the tap on the filling loop and fill the system until a pressure of 1.5 bar has been
reached (light no.11 ON) and then close the tap on the filling loop.
§
The automatic ignition system will turn the burner on.
§ Should the boiler fail to ignite: if the display (14) shows value 04 flashing, it is necessary to repeat the procedure of
filling the system; if the display (14) shows value 01 flashing wait 3 minutes; set the ON/OFF button (1) to OFF
position and then ON position (fig.1). It may be necessary to repeat the procedure a few times to purge air
from the pipes. Do not repeat the procedure for more than 3 times. If locking-out persists, turn boiler OFF and call
an authorised radiant service engineer.
After a regular boiler ignition, push Pad 6 to select heating mode (led 9 ON intermittent) or D.H.W. mode (led 8 ON
intermittent);
