Common venting up to four boilers.
Gas fuel flexibility (NG/LPG/LNG) with a simple electronic conversion.
Low inlet gas pressure requirement (NG) as low as 4 inches of water column for compatibility with a range of supply pressures.
Large water content extends burner run time and reduces cycling.
No dedicated boiler pump required due to extremely low water pressure drop through the heat exchanger – no low-loss header required.
Generous stainless steel heat transfer surface area for maximum heat extraction.
Seamless integration with building management systems.

VITOCROSSAL 300

CA3B Series high-efficiency, gas-fired condensing boiler with Inox-Lamellar heat exchanger surface made of high-grade stainless steel. Rated input: 2500 to 6000 MBH
