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.
