Project Description
Features
- Wide modulation ratio up to 1:7 better efficiency and noiseless operation
- 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
