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

Turning on procedure for electronic ignition (only for U.k. and Ireland):
turn on the gas cock situated under the boiler grill;
turn selector switch 1 to the symbol denoting winter (see fig.2);
make sure that 6 light is ON (see fig. 2 pag. I) and the no.14 or no.15 lights are ON (see fig. 2); if light no.13 flashes, 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.15 ON; see fig. 2) and then close the tap.
The automatic ignition system will turn the burner on.
It may be necessary to repeat the procedure a few times to purge air from the pipes. To repeat the ignition procedure press
release button 2 (see fig. 1) and then try the ignition procedure once again. If the boiler does not start, press the reset button
(see fig. 1 pag. I). IMPORTANT should the boiler fail to ignite wait 3 minutes before pressing button again.
If locking-out persists, turn boiler OFF and call
RADIANT HELP LINE - 01329.828555.
