This appliance is designed to produce hot water for domestic use.
It should be connected to a heating system and a distribution
network for domestic hot water, both of which must be compatible
with its performance and power levels.
The use of the appliance for purposes other than those specifi ed is
strictly forbidden. The manufacturer cannot be held responsible for
any damage caused by improper, incorrect and unreasonable use of
the appliance or by the failure to comply with the instructions given
in this manual.
Installation, maintenance and all other interventions must be carried
out in full conformity with the governing legal regulations and the
instructions provided by the manufacturer. Incorrect installation
can harm persons, animals and possessions; the manufacturing
company shall not be held responsible for any damage caused as a
result. The boiler is delivered in a carton. Once you have removed all
the packaging, make sure the appliance is intact and that no parts
are missing. If this is not the case, please contact your supplier.
Keep all packaging material (clips, plastic bags, polystyrene foam,
etc.) out of reach of children as it may present a potential hazard.
In the event of a fault and/or malfunction, turn the appliance off ,
turn off the gas cock and do not attempt to repair it yourself. Contact
a qualifi ed professional instead.
Before any maintenance or repair work is performed on the boiler,
make sure you have disconnected it from the electricity supply
by switching the external bipolar switch to the “OFF” position and
removing the fuse.
All repairs, which should only be performed using original spare
parts, should be carried out by a qualifi ed professional. Failure
to comply with the above instructions could compromise the
safety of the appliance and invalidate all liability on the part of the
manufacturer.
In the event of any maintenance or other structural work in the
immediate vicinity of the ducts or fl ue gas exhaust devices and
their accessories, switch the appliance off by switching the external
bipolar switch to the “OFF” position and shutting off the gas control
valve. When the work has been completed, ask a qualifi ed technician
to check the effi
ciency of the ducting and the devices.
Turn the boiler off and turn the external switch “OFF” to clean the
exterior parts of the appliance.
Clean using a cloth dampened with soapy water. Do not use
aggressive detergents, insecticides or toxic products. If the appliance
is used in full compliance with current legislation, it will operate in a
safe, environmentally-friendly and cost-effi
cient manner.
If using kits or optional extras, make sure they are authentic.
