The Series 4S uses the very latest design techniques and standards. Its furnace is designed for low volumetric release rates of no more than 136,000 btu per hour per cubic feet. The design incorporates positive water flow circulation and maximum heat transfer to maximize ratings. The lower the release rates, the easier the boiler works. The Series 4S is also easily converted to a Low NOx product when needed. All external trim piping is designed and installed in accordance with the ASME Code and is certified by an independent inspection agency for compliance.
