Weil-mclain 672619163713 EG-40 45 Series Gas Boiler Section Assembly with Tankless Opening

Product Description

The Weil-McLain 672619163713 is a cast iron section assembly designed for use with EG-40 and EG-45 Series 1 through 5 atmospheric gas boilers. This assembly includes a tankless opening and is built to support both water and steam heating systems running on natural gas. HVAC technicians and boiler installers rely on this type of section assembly when building or rebuilding EG-series boilers from the ground up. Cast iron construction gives the assembly long-lasting durability and excellent heat retention, which are key requirements for residential and light commercial heating applications. The EG series from Weil-McLain has been a trusted platform in the hydronic heating industry for decades, and replacement or new-installation assemblies like this one keep those systems running efficiently. This section assembly is a core structural and functional component of the boiler. It houses the heat exchanger sections that transfer heat from the combustion gases to the water or steam in the system. The tankless opening allows for integration of a tankless coil, which can provide domestic hot water when paired with the correct coil accessory. Installers should consult the boiler manual to identify all additional required components needed for a complete boiler installation. This assembly is not a standalone unit and must be combined with other specified parts to form a fully operational boiler. Proper sizing and compatibility with the EG-40 and EG-45 Series 1 through 5 models must be confirmed before ordering. This part is intended for use with natural gas configurations only and is not rated for propane or oil-fired applications.
