Viessmann Gas Boilers – Vitocrossal 300
Viessmann Gas Condensing Boilers: 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
- Low emissions and quiet operation from fully-modulating Viessmann pre-mix cylinder burners (up to 3)
- Total burner modulation turndown ratio of up to 16:1 precisely matches load per boiler
- The fully assembled boiler simplifies installation and commissioning
- 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
- Easy changeover from NG to LP with a simple turn of a key (Dual Fuel models)
- Low inlet gas pressure capability as low as 4″ w.c. (NG) for compatibility with a range of supply pressures
- Large water content extends the burner run time and reduces cycling
- No dedicated boiler pump required due to extremely low water pressure drop through the 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
