- Flexibility for venting through the sidewall or chimney applications and combustion air options of sealed combustion or room dependent
- Common venting up to four boilers *
- Gas fuel flexibility NG/LP (Dual Fuel**)
- Low inlet gas pressure capability as low as 4" w.c. (NG) 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 heat exchanger
- Vitotronic 300 GW6C can be used as a single boiler control or as a cascade primary/secondary control system
- Seamless integration with building management systems

Exceptional performance and reliability
The titanium infused stainless steel Inox-Lamellar heat exchanger surface provides maximum heat extraction while maintaining a compact size. Its smooth, corrosion-resistant surfaces allow condensate to simply run off – a "self-cleaning" process that ensures continuous condensing efficiency, reduced maintenance costs and longevity.
Combined with our fully-modulating pre-mix cylinder burners, the Vitocrossal 300 CA3B achieves outstanding thermal efficiencies over 96% and delivers exceptional performance and reliability at an attractive price.
