Gas Fireplace

Abstract

A gas fireplace comprises a support and housing frame, a gas combustion chamber, at least one chimney duct for releasing flue gases, coming from said combustion chamber, at least one inlet duct for external comburent air leading to said combustion chamber, a ventilation and heating circuit designed to suck environment air, and heat and fed it at least partly into the space where the fireplace is located, and at least one motor-driven fan designed to operate in said ventilation and heating circuit. The gas fireplace further comprises at least one silencer device provided along said ventilation and heating circuit.

1 . A gas fireplace comprising a support and housing frame, a gas combustion chamber, at least one chimney duct for releasing flue gases coming from said combustion chamber, at least one inlet duct for external comburent air leading to said combustion chamber, a ventilation and heating circuit designed to suck environment air, and heat and feed it at least partly into the space where the fireplace is located, and at least one motor-driven fan designed to operate in said ventilation and heating circuit, wherein at least one silencer device is provided along said ventilation and heating circuit.  
   
   
       2 . A gas fireplace as claimed in  claim 1 , wherein said at least one silencer device is arranged upstream or downstream of a respective motor-driven fan.  
   
   
       3 . A gas fireplace as claimed in  claim 1 , wherein the or each chimney duct and a respective inlet duct for external comburent air are arranged one inside another thereby delimiting a gap through which a comburent air flow is in countercurrent heat exchange relationship with flue gases flow in said chimney duct.  
   
   
       4 . A gas fireplace as claimed in  claim 1 , wherein said inlet duct for external comburent air is designed to feed comburent air to said combustion chamber with no pre-heating of the comburent air.  
   
   
       5 . A gas fireplace as claimed in  claim 1 , wherein said ventilation and heating circuit comprises at least one ventilation chamber.  
   
   
       6 . A gas fireplace as claimed in  claim 1 , wherein said motor-driven fan has a suction side thereof in fluid communication with at least one ventilation chamber and a delivery side thereof in fluid communication with at least one heated room air feeding duct.  
   
   
       7 . A gas fireplace as claimed in  claim 1 , wherein said at least one ventilation chamber is located in heat exchange relationship between said at least one comburent air chamber and said combustion chamber.  
   
   
       8 . A gas fireplace as claimed in  claim 1 , wherein said at least one ventilation chamber is located outside said at least one comburent air chamber and in heat exchange relationship therewith.  
   
   
       9 . A gas fireplace as claimed in  claim 1 , comprising a hood delimiting an upper space for room air to be heated and conveyed to said ventilation and heating circuit.  
   
   
       10 . A gas fireplace as claimed in  claim 1 , comprising at least one humidification device for heated air delivered into the room.  
   
   
       11 . A gas fireplace as claimed in  claim 1 , wherein said at least one combustion chamber of said ventilation and heating circuit in heat exchange relationship with said at least one comburent air chamber and said combustion chamber has a plurality of finnings.
