* open the gas tap;
* set the power mains switch to
ON;
* set the desired boiler
operating mode through switch
A
Summer/OFF/Winter/Anti-
freeze; power light B comes on.
Sselecting the Summer mode
the boiler supplies DHW only;
selecting the Winter mode the
boiler supplies both central
heating and DHW; with the
Anti-freeze mode central
heating and DHW functions are
not active and the boilers is
protected against freezing;
* set the temperature value
desired for the central heating
through the CH regulator C;
* set DHW temperature through
knob
D; if the water
temperature in the storage tank
is lower than the one set on the
boiler, the boiler automatically
heats it to the set value. The
boiler prioritizes DHW and
water tank temperature
holding functions to central
heating function. Control
knob allows setting of
temperature in a 40 °C to 60 °C
range: when the knob is in
middle position DHW is set to
approximately 50 °C;
* set room temperature through
the ambient thermostat if
available;
Warning: when starting the
boiler after a long period of
inactivity, particularly boilers
powered by LPG, air bubbles
may be present in the supply
line.
Before switching on the boiler
switch on another gas powered
device (e.g. Light a kitchen gas
appliance).
The boiler may still shut down
once or twice.
If boiler shuts down use the
reset button F to resume
operation (see below).
1.2.2 Boiler shutdown
In case of malfunction the boiler
automatically turns off: the
shutdown light E on the control
panel comes on. Then follow
the below instructions:
* check that the gas tap is open
and that gas is flowing, for
example by lighting a kitchen
gas appliance;
* if there is gas supply wait for a
minute before restarting the
boiler using reset button F if the
boiler does not restart, try to
reset the boiler three additional
times. Should the boiler still not
resume operation, call an
authorised Service Centre or
qualified maintenance
personnel.
If the boiler shuts down
frequently, this indicates that
there is a recurring
malfunction. In this case
contact qualified personnel or
an authorised Service Centre
for maintenance.
WARNING
In order to prevent flue gas
leaks, natural draught boilers
are fitted with a safety device
with automatic reset. When
the safety device detects a
leak, the boiler holds standby
mode for 15 minutes.
Should the above mentioned
boiler status frequently
occur, the flue system is not
properly functioning. In this
case contact a qualified
technician to check the flue
system. A persistent
malfunction in the flue
system might put people and
animals at risk.
1.3 Maintenance
The boiler must be serviced
once a year.
Correct servicing ensures boiler
performance, prevents
environment pollution and
potential danger for people,
animals and property.
The boiler must be serviced by
qualified personnel. FONDITAL
strongly recommends
customers to refer exclusively
to qualified personnel.
The user may only clean the
exterior boiler housing using
domestic products .
Do not use water!
1.4 Information for the user
The user can access only the
parts of the boiler which can
be reached without using
tools: it is therefore forbidden
to disassemble the exterior
cover of the boiler and
tamper with the interior parts.
NO-ONE, INCLUDING
QUALIFIED PERSONNEL,
MAY MAKE MODIFICATIONS
TO THE BOILER.
FONDITAL cannot be held
liable in the event of injury to
persons and animals and
damage to property resulting
from tampering or improper
operations on the boiler.
If the boiler is inactive and
disconnected from the power
supply for long periods the
pump might be blocked and it
may be necessary to manually
turn the pump rotor to resume
its operation.
The above mentioned
operation, which requires
disassembling the boiler
housing and accessing internal
parts of the boiler, must be
performed by qualified service
personnel.
It is possible to prevent the
pump from blocking by adding
special filming products suitable
for multi-metal systems to the
water.
If the boiler is not disconnected
from the mains power supply,
