Biasi SG Pro Series
Page 7
The BIASI SG Pro-series boilers are wet base design, sectional, cast-iron boilers for
forced hot water heating systems. The boilers are shipped pre-assembled from the factory in
lengths from three to seven sections. They are designed for firing with oil or gas power
burners, which are packed separately along with the jacket and controls for shipping purposes.
When the boiler is received, check the contents to ensure that there is no shortage or
damage to any part of the boiler system. With every boiler you should receive a boiler block,
jacket, trim kit and a burner (oil or gas).
