This appliance has been manufactured 
specifically for room heating and must be used 
for this purpose. Contractual liability of the 
manufacturer in respect of damages caused 
to people, animal or premises by incorrect 
installation, settings, maintenance or by 
improper use of the heater is excluded.

During the initial start-up, there may be the 
formation of odours and fumes due to the 
evaporation of the oil added to protect the 
heat exchanger during storage; this is normal 
and will disappear after a short period. It is 
recommended to ensure suitably ventilation 
for room.

If the appliance is to remain 
unused for long periods, it is 
recommended that the following 

operations are carried out:

•  Turn the appliances’ electrical supply off via 

the local isolator.

•  Close the main fuel supply valve

•  If there is a long period of time between 

operation, it is recommended that you 
contact your installer to carry out the new 
start-up.

The heater shall be fitted with approved 
accessories only. The manufacturer is not liable 
for damages arising from the improper use 
of the heater or from the use of non-original 
materials or accessories. References to Laws, 
Regulations, Directives and Technical Rules 
mentioned in this manual are provided only for 
information purposes and are in force when 
the manual is printed.

The introduction of new provisions or 
amendments to current laws does not 
represent an obligation of the manufacturer 
towards third parties. Repairs or maintenance 
are to be performed by trained personnel only. 

Do not modify or tamper with the appliance, 
the manufacturer will not be held responsible 
for any third party modifications to the heater. 

The services that are to be connected (fuel 
pipes, power supply, etc.) must be suitably 
secured and must not be dangerous with the 
risk of tripping.

The manufacturer is responsible for the 
product compliance with Laws, Directives or 
Construction Rules in force when the product 
is marketed. The knowledge and observance 
of the laws and standards regarding 
plant design, installation, operation and 
maintenance are the sole responsibility of the 
designer, installer and user. 

The manufacturer shall not be held responsible 
for failure to comply with the instructions 
of this manual, for the consequences of any 
operations carried out and not specifically 
provided for or for translations open to 
misinterpretation.

The electrical system must feature suitable 
individual and independent electrical 
protection for each appliance which, in case 
of accidental failure, will be activated on the 
single appliance without prejudice to the 
proper operation of the other units present on 
the installation.

Note: 
The appliance is designed to be operated 
with the heating capacity and the air 
flow rate specified in the Data Sheet. If 
the heating capacity is too low and/or 
the air flow rate is too high, combustion 
products may condensate, resulting in 
the irreparable corrosion of the heat 
exchanger. If the heating capacity is too 
high and/ or the air flow rate is too low, 
overheating of the heat exchanger may 
occur, resulting in the  activation of the 
high temperature safety devices and could 
cause damage to the exchanger

Disposal instructions

Disposing of the appliance must be done by an 
authorised company and in compliance with  
the applicable laws. Before taking waste to 
Authorised Collection Centres, dismantle and 
separate the various materials that compose it 
which in summary are
