1. OPERATING INSTRUCTIONS

1.1 Introduction

Dear Customer,
Thank you for choosing the OPTIMAX HE PLUS 18 S, a FERROLI wall-mounted boiler of the latest
generation, featuring advanced design and cutting-edge technology.
OPTIMAX HE PLUS 18 S is a high-efficiency condensing pre-mix appliance for heating with extremely
low emissions, running on natural gas or LPG.
The boiler consists of an aluminium laminar heat exchanger providing effective condensation of the
water vapour contained in the flue gases, permitting extremely high efficiency.
Above the heat exchanger, in the boiler, there is a pre-mix burner, with a large ceramic surface, equip-
ped with electronic ignition and ionization flame control, which achieves extremely low emissions while
ensuring high reliability and long life operation.
The boiler is totally room sealed from the installation room: the air needed for combustion is drawn
from outside. The boiler also includes a modulating speed fan, modulating gas valve, pump, expansion
vessel, safety valve, temperature sensors, a safety thermostat and a low water pressure sensor.
Thanks to the microprocessor control and adjustment system with advanced self-diagnosis, unit ope-
ration is for the most part automatic. The power for heating is automatically governed by the control
system.
The user only has to set the temperature desired inside the home by means of a room thermostat and
appliance temperature control. The adjustment and control system will provide optimum operation
throughout the year.
The display continuously provides information on the unit's operating status and it is easily possible
to obtain additional information on the sensor temperatures, set-points, etc. or configure them. Any
operating problems associated with the boiler or system is immediately signalled by the display and, if
possible, corrected automatically.
