1. TECHNICAL CHARACTERISTICS AND DATA
1.1 Introduction
Our appliance is a high-efficiency heat generator for central heating running on natural gas or LPG
(configurable at the time of installation).
The boiler shell consists of a copper laminar exchanger whose particular shape guarantees high
exchange efficiency under all operating conditions and an open-flue burner equipped with electronic
ignition and ionization flame control.
The boiler is totally sealed off from the installation room: the air needed for combustion is drawn from
outside and the flue gases are expelled by a fan. The boiler outfit moreover includes a variable speed
circulator, expansion tank, safety valve, filler cock, air pressure switch, water pressure switch,
temperature sensor and a safety thermostat.
Thanks to the control and adjustment system, unit operation is for the most part automatic. The power
for heating is automatically governed by the control system according to the indoor characteristics, the
characteristics of the building and of its location.
There are 5 LEDs on the control panel providing information on the units operating status.
