1. OPERATING INSTRUCTIONS

1.1 Introduction

Dear Customer,
Thank you for choosing the 

FERSYSTEM TECH 38 C

, a FERROLI wall-mounted boiler of the latest 

generation, featuring advanced design and cutting-edge technology. 

FERSYSTEM TECH 38 C

 is a high-efficiency 

condensing pre-mix

 appliance for heating and hot water 

production 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, flow sensor, temperature sensors, a safety thermostat and a low water pressure switch.
Thanks to the 

twin microprocessor

 control and adjustment system with advanced self-diagnosis, unit 

operation 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.
