Weil-mclain 672619163751 Block Section Assembly EG-65 with Tankless Opening

Product Description

The Weil-McLain 672619163751 Block Section Assembly is a cast iron boiler section designed for use with the EG-65 series boiler. This assembly includes a tankless opening, which allows for the integration of an indirect water heating coil or tankless heater within the boiler block. HVAC technicians and heating professionals rely on block section assemblies like this one to repair, replace, or expand the heating capacity of cast iron sectional boilers. The EG-65 is a long-standing Weil-McLain residential and light commercial cast iron boiler known for its durability and reliable hydronic heating performance. When a boiler section cracks, leaks, or fails due to thermal stress or age, replacing the individual block section is often more cost-effective than replacing the entire boiler. This part restores proper water flow, pressure containment, and heat transfer within the boiler block. Cast iron sectional boilers are built in sections that are connected using push nipples and draw bolts, allowing individual sections to be replaced in the field. The tankless opening on this block section provides a port for mounting a tankless coil, enabling domestic hot water production directly from the boiler. This is a common configuration in older hydronic heating systems where a single boiler serves both space heating and domestic hot water needs. Heating contractors, boiler service technicians, and mechanical engineers working on EG-series Weil-McLain equipment will recognize this as a direct OEM replacement section. Proper installation requires following Weil-McLain assembly procedures including section alignment, nipple seating, and pressure testing before returning the boiler to service. This part weighs approximately 200 pounds, which is typical for a cast iron boiler block section of this size and should be handled with appropriate lifting equipment during installation.
