Page 30: Soft Ignition
Soft ignition Soft ignition pressure is automatic and it needs no adjustment. • The ignition is achieved by means of a burst of electrical sparks, while the burner is supplied with gas, initially to the MIN pressure set on the valve gas, then pressure increases gradually (soft igni- tion ramp) until the ignition takes place. -

Gas conversion ATTENTION: the operations described below must be carried out only by qualified personnel (authorized by the Manufacturer or by the local authority, if required by the regulation). For gas conversion, use the nozzles supplied by boiler manufacturer only. Using LPG, it is absolutely necessary to install a suitable pressure reducer upstream the boiler. -

Page 46: Addendum
Addendum Outdoor Sensor Kit Installation and setting The Outdoor Sensor manages automatically the CH flow temperature** as a function of the outdoor temperature, thus avoiding the user to adjust it manually. This function is also named "shifting tempera- ture"� that's the temperature of the heating elements. Don't mistake it with the room temperature (managed by the room thermo- stat or by the Remote Control, but not by the boiler) that doesn't depend on the first one. -
Page 47: Remote Control Kit
Remote Control Kit This remote control is more than a simple room thermo- stat. Thanks to this, it is possible to manage the boiler in all its settings like DHW and CH temperature adjustment, boiler reset in case of boiler block, and of course it works as a room thermostat both in manual and weekly program mode. - Page 48 Notes Green Heating Technology...
