Wall Hung Boiler – Cod. 99817NA – July 2001 

 

 

TECHNICAL DATA 

 

Type B unit 

Type B boilers have open combustion chambers, and must be connected to a 

flue duct to convey combustion exhaust out of the room. Air for combustion is 

taken directly from the room in which the boilers are installed. 
 

Type C unit

 

Type C devices are devices in which the combustion circuit (air intake, 

combustion chamber, exchanger, combustion exhaust) is sealed off from the 

place where they are installed.
