  • Gas Adaptive Control (GAC) system: combustion automatic control to maintain constantly the highest level of efficiency
  • Telescopic connection pipes with gas and mains water valves for outdoor wall-mounted installation available as optional
  • Covering kit for open air wall-mounted installation available as optional
  • Hydraulic circuit automatic filling
  • Minimum working temperature: -15°C
  • Connection to rigid and flexible Ø50 mm flue pipe: solution for chimney refurbishment and replacement of an existing open flue gas boiler, 40 max length (mod. 24 kW)
  • Digital control panel with back-lighted LCD display
  • High efficiency full modulating circulating pump
  • Integration with solar system option
  • Completely painted, also on the back to grant a higher protection against
    atmospheric agents
