Vaillant coaxial chimney is a special chimney for condensing boilers consisting of two parts. One part is coaxial 60/100 built on the principle of "pipe in pipe" for connection to the outputs of the boiler with a capacity of up to 33 kW. The second part is a turn with a transition of 60 mm. to 80 mm. for connecting chimneys with a diameter of 80 mm. up, Oxygen for combustion is forcibly taken from the shaft in the wall of the house, and then enters the outer pipe of the coaxial chimney with a diameter of 100 mm (steel). Combustion products are emitted through the inner pipe of the coaxial chimney with a diameter of 60 mm (polypropylene PP) and then pass into the chimney of 80 mm. purchased separately. The 60/100 boiler connection angle has a special “two-piece” for inspection and cleaning of the chimney and is suitable for acceptance of the chimney by the Ministry of Emergency Situations employees as a “cleaning hatch”. The 60-80 transition angle has a special device for fastening in the shaft, which allows accepting the load from additional vertically installed chimneys. #chimney#Coaxialchimney#chimneyforcondensingboiler#coaxialchimneyVaillant#chimneyVaillant#plumber#plumberBrest#chimneyforexistingshaft#plumbingconstruction
