Product Description

The Weil-McLain 672619218864 is a cast iron natural gas steam boiler from the EG Series 6 collection. It is designed for residential floor-mount installations where reliable steam heat is needed. This unit delivers 100,000 BTU input and 85,000 BTU heat output, making it well suited for older steam heating systems found in homes and multi-family buildings. HVAC technicians and heating contractors will recognize this boiler as a dependable replacement or new-install option for steam-based hydronic systems. The cast iron heat exchanger is built for long service life and holds up to the repeated thermal cycling common in steam applications. The boiler runs on natural gas only and uses a spark ignition system for intermittent electronic ignition. This eliminates the need for a standing pilot, which reduces fuel waste between heating cycles. The unit is rated up to 84% AFUE, helping to limit fuel consumption over the heating season. Access to controls is straightforward, which speeds up commissioning and routine service calls. The boiler comes packaged with several key components already included: a 15 psi ASME relief valve, gauge cocks and glass, and a syphon. These pre-included parts reduce job site sourcing time and help installers get the system running faster. The supply pipe connection measures 3 inches and the return pipe connection measures 2.5 inches, which are standard sizes for steam systems. The unit measures 33.75 inches tall, 27.625 inches deep, and 17 inches wide. It operates on 120V single-phase power with an automatic vent configuration. The boiler carries ASME H certification and is UL Listed, meeting the safety and code requirements for residential steam heating equipment.
