1.1 General safety instructions  

 

This appliance must only be used for the function for which it was designed: "Gas fired air heater". Any 
other use is to be considered improper and dangerous. Franco s.r.l. cannot be held responsible for any 
damage resulting from improper, incorrect and unreasonable use or if the appliance is used in systems 
that do not comply with the safety regulations in force. 

 

Check the integrity of the appliance when  you open the packaging, paying particular  attention to the 
presence of damage or deformation that could lead to breakage and/or malfunction during use. In such 
cases,  do  not  connect  the  machine to the  electricity  and  gas mains.  Periodically  carry  out  a  general 
check of the appliance.

 

 

Observe the safety rules indicated for electrical equipment and in particular:  

 

  Follow the installation instructions of the appliance. 

  Do not place any objects on the air heater. 

  Do not allow children and/or incapacitated persons to operate the unit without proper supervision; 

  Do not touch the unit during operation or during the cooling phase. 

  Never immerse the device in water or any other liquid. 

 

  Do not put any objects inside the machine as this may cause irreparable damage. 

  Do  not  use  accessories,  spare  parts  or  components  not  specified  or  supplied  by  the 

manufacturer. 

  Avoid touching the device with wet or damp hands. 

  Do not pull the power cords or expose them to a risk of shearing. 

  Do not leave the device directly exposed to the weather (rain, sun, etc.). 

  In case of failure or malfunction, turn it off immediately and disconnect the power and gas supply.  

  Do not attempt to open or tamper with the appliance: contact a qualified technician. 

 

1.2 Guidelines for the correct disposal of the product  

 

Pursuant to European Directive 2012/19/EU: 
At the end of its useful life, the product must not be disposed of with urban waste. 
It can be delivered to the special separate waste collection centres set up by the municipal 
authorities,  or  to  retailers  who  provide  this  service.  Disposing  of  the  product  separately 
avoids possible negative consequences for the environment and for health deriving from 
its inappropriate disposal and allows the recovery of the materials of which it is composed 
in  order  to  obtain  an  important  saving  of  energy  and  resources.  To  emphasize  the 
obligation to dispose of electrical and electronic equipment separately, the product bears the crossed-
out wheeled bin mark.
