Weil-mclain 672619218871 Pegtm Series 5 Packaged Gas-fired Cast Iron Steam Boiler 125 Mbh 82.9% Afue

Product Description

The Weil-McLain 672619218871 is a packaged gas-fired cast iron steam boiler from the PEGTM Series 5 collection. It is built for residential floor-mount installations and delivers 125 MBH of input capacity with a BTU heat rating of 146,000 BTU per hour. The unit runs on natural gas only and achieves an 82.9% AFUE rating, giving homeowners solid fuel efficiency without the complexity of a condensing system. HVAC professionals will recognize this as a dependable drop-in replacement or new-install option for steam heating systems in older homes and multi-unit residential buildings. Cast iron construction means the heat exchanger holds up to the thermal cycling demands of steam systems over many years of service. The boiler uses a spark ignition system, also known as intermittent electronic ignition, which eliminates the need for a standing pilot light and helps reduce gas waste. A high-limit pressure control is factory-installed to protect the system from over-pressurization. The unit ships with a 15 PSI ASME-rated relief valve, gauge cocks, a sight glass, and a syphon, so installers have the critical safety and monitoring components ready to go. The B-Vent or L-Vent configuration makes it compatible with standard residential venting setups, simplifying retrofit jobs. The supply pipe connection measures 3 inches and the return pipe connection measures 2-1/2 inches, which are standard sizes for residential steam systems. The cabinet is designed with easy access to the controls, cutting down service time on maintenance calls. The unit is CSA certified and UL listed, confirming it meets recognized North American safety standards. It covers up to 325 square feet of net AHRI steam radiation. Overall dimensions are 38-7/8 inches in height, 27-5/8 inches in depth, and 21-1/4 inches in width, making it suitable for tight mechanical rooms.
