INSTALLATION 

 

WARNING! 

The following operations must be carried out by qualified personnel only. 
 
ELECTRIC CONNECTIONS AND SETTINGS: 

WARNING! 

The main heater electricity supply has to be provided with grounding and a magneto-thermal switch 
with a differential. The power wire has to be connected to a switch board linked to a disconnecting 
switch. 

The  basic  equipment  of  the  heater  includes  all  control  and  safety  devices  which  can  guarantee  the  correct 
functioning  of  the  machine:  control  board,  room  thermostat  (2),  fan  and  manual  safety  thermostat  are  already 
connected.      
The following operations have now to be carried out: 
 

 

Plug the power wire in after having read the adhesive label that shows electricity supply characteristics; 

  
After  having  completed  those  operations,  make  carefully  sure  that  all  the  electric  connections  match  with  the 
wiring  diagram.  When  the  heater  gets  turned  on  for  the  first  time,  you  should  make  sure  that  the  fan  does  not 
absorb more current than the maximum indicated limit. Eventually, to regulate the burner, follow the instructions 
of the burner manual.  

 
HOT AIR DUCTS CONNECTION 

The space heater provides heat by releasing and diffusing hot air. 
An air head which can be connected to air ducts, if the users chooses this option, is supplied with every machine. 
In this case, and in particular if the diameter and length of the ducts get changed, or if the number of bends gets 
modified,  air  output  may  vary.  Consequently,  it  is  very  important  to  check  and  regulate  air  output  when  any 
modification is made to air heads or ducts. 
In all circumstances, you should make sure that: 

 

The fan engine does not absorb more current than the maximum indicated limit. 

 

The air flow volume matches with its recommended level. 

 
CHIMNEY AND CHIMNEY FLUE CONNECTION 

Efficient combustion and trouble-free working of the burner depend on an efficient smoke evacuation: 

 

The pipe which through which smoke passes should as short as possible and ascending. 

 

There should be no sharp bends and the diameter of the pipe should never be reduced. 

 

Every heater should have its own chimney. 

 

The chimney draught should at least enough and adequate for the needs of the equipment. 

 
  

WASTE PRODUCTS ANALYSIS 

The probes to check the combustion waste products composition and smoke temperature have to be positioned as 
the picture below indicates. 

 

When  those  tests  have  been  completed,  the  hole  drilled  has  to  be  sealed  using  a  high  temperature  resistant 
material which will ensure that the pipe remains airtight.
