manuale d’uso

Dear Customer,

Thank you for choosing an ARISTON boiler.

We guarantee that your boiler is a reliable and

technically sound product.

This manual provides detailed instructions and 

recommendations for proper installation, 

use and maintenance.

Remember to keep this manual in a safe place

for future reference i.e. by the gas meter.

Your local ARISTON Servicing Centre is at your 

complete disposal for all requirements.

The  installation  and  first  ignition  of  the  boiler  must  be 

performed by qualified personnel in compliance with current 

national regulations regarding installation, and in conformity 

with  any  requirements  established  by  local  authorities  and 

public health organisations. 

After the boiler has been installed, the installer must ensure 

that the end user receives the declaration of conformity and 

the  operating  manual,  and  should  provide  all  necessary 

information as to how the boiler and the safety devices should 

be handled.

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 specified 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. 

In  the  event  of  any  maintenance  or  other  structural  work  in  the 

immediate  vicinity  of  the  ducts  or  flue  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 valve. 

When the work has been completed, ask a qualified technician to 

check the efficiency of the ducting and the devices. 

If the boiler should be out of use for a prolonged period, it is 

recommended that the electrical power supply be disconnected 

and that the external gas cock be closed. If low temperatures are 

expected, the boiler and system pipe work should be drained in 

order to prevent frost damage.

Turn the boiler off and turn the external switch “OFF” to clean the 

exterior parts of the appliance. 

Do not allow children or inexperienced persons to use the 

appliance without supervision.
