3.1.1. GENERAL USE WARNINGS
WARNING
Before starting the boiler the User must
make sure that the First start-up certificate has the
stamp of the technical Support Centre proving the
testing and the first start-up of the boiler.
WARNING
To validate the warranty, the boiler must
be started by a technical Support Centre authorized
by RADIANT no later than 30 days from the date of
installation.
WARNING
In order to take advantage of the guarantee
provided by the manufacturer, the customer should
carefully and exclusively observe the instructions
given in the USER section of the manual.
ATTENTION
This machine may be used only for the
purpose for which it has been designed: heat water
to a temperature below boiling point at atmospheric
pressure. Any other use is considered wrong and
dangerous. The manufacturer is excluded from
any contractual or out of contract responsibility for
damage caused to people, animals or property due
to incorrect use.
DANGER
The boiler should not be used by persons
(including children) with reduced physical, sensory or
mental capacities or without suitable knowledge or
experience unless they are instructed on the device
use or monitored by a person responsible for their
safety.
DANGER
DO NOT obstruct the air vents of the
location in which the gas device is installed to prevent
the formation of toxic explosive mixes.
DANGER
If you sense a gas odour in the location in
which the boiler is installed, proceed as follows:
› DO NOT use electrical switches, the telephone or
any other device that might generate electrical
discharges or sparks;
› Immediately open all doors and windows to
create an air exchange that can quickly clean
the location;
› Close the gas valves;
› Request immediate intervention of qualified
staff.
DANGER
The use of the electrical power boiler
implies respecting some fundamental rules such as:
› DO NOT touch the device with wet and/or humid
parts and/or with bare feet;
› DO NOT pull the electrical cables;
› DO NOT leave the device exposed to atmospheric
agents (rain, sun, etc.) unless specifically
intended;
› in case of cable damage, turn off the device and
contact qualified professional staff to replace it.

3.1.5. START-UP
Before starting the boiler make sure that it is
powered and that the gas tap below the boiler is
open.
To start the boiler press the function key ‘
’ and select the desired operating mode. If the
symbol is displayed fixed, it means that the function
was activated.
3.1.6. OPERATING MODE
ONLY HEATING MODE
In this mode the boiler meets only the demands of
heating.
To switch the boiler to ONLY HEATING operating
mode, press the function key ‘ ’, the symbol ‘
’ will appear fixed on the display, indicating that
the function is enabled.
Whenever heating energy is needed to heat the
rooms the automatic start-up system will start the
burner; this is indicated by displaying the symbol ‘
’ blinking.
ADJUSTING THE HEATING TEMPERATURE
You can adjust the temperature using keys ‘ ’
and ‘ ’ of the heating circuit :
· press key ‘ ’ to decrease the temperature.
· press key ‘ ’ to increase the temperature.
The heating temperature adjustment field ranges
from 30 °C to 80 °C (25 °C – 45 °C for floor systems).
OFF MODE
In this mode the boiler no longer meets the heating
demands, the anti-freeze and pump anti-locking
systems still remain active.
To switch the boiler to OFF operating mode, press
the function key ‘ ’, the symbol ‘ ’ will
appear fixed on the display, indicating that the
function is enabled (for non condensing models
will appear the message ‘OFF’).
If the boiler was previously r unning, it will be turned
off and the post-ventilation and post-circulation
functions will be enabled.
If you have to deactivate the boiler for a long period
of time, proceed as follows:
› contact the Technical support centre that will
empty the water system, where no anti-freeze
is intended, and will cut off the power, water and
gas supply.
› Or leave the boiler in OFF operating mode
keeping active the electrical and gas supplies so
that the anti-freeze function may activate.

3.1.7. INFORMATIONAL NOTE ON
ANTI-FREEZE FUNCTION
The boiler is protected against freezing thanks to
the electronic board preparation with functions
that start the burner and heat the concerned parts
when their temperature goes below the minimum
pre-set values.
WARNING
This function is available only if:
› the boiler is powered;
› the gas supply is open;
› the pressure of the system is proper;
› the boiler is not blocked.

3.1.8. SYSTEM FILLING
To restore the water pressure inside the system
open the loading tap “R” (fig. 1) and make sure
using pressure gauge “M” (fig. 1), that the system
pressure reaches 1.2 bar (see fig. 2).
After performing this operation, make sure that
the loading tap “R” (fig. 1) is properly closed.
After the water pressure reset the boiler will
automatically perform a 2 minutes system relief
cycle. Throughout this function the display will
show the code “F33”. The boiler can work normally
only after completing the operation.
