Product Description

The Weil-McLain 672619218888 is a packaged, gas-fired cast iron steam boiler from the PEGTM Series 5 collection. It is designed for residential floor-mount installation and delivers reliable, consistent heat output for single-family homes and similar applications. This unit operates on natural gas and produces 150 MBH of input capacity with a BTU heat rating of 176,000 BTU per hour. The Annual Fuel Utilization Efficiency rating is 82.9% AFUE, meaning it converts a strong portion of the fuel it consumes directly into usable heat. Cast iron construction gives this boiler long-term durability and resistance to the thermal stress that comes with repeated heating and cooling cycles. HVAC technicians and heating contractors will recognize the PEGTM Series 5 as a dependable workhorse for steam heating systems in older residential buildings and retrofit projects. The boiler uses an intermittent electronic spark ignition system, eliminating the need for a standing pilot light and improving overall efficiency. A high-limit pressure control is built in to protect the system from unsafe pressure conditions. The unit ships with a 15 PSI ASME-rated relief valve, gauge cocks and glass, and a syphon, so technicians have the critical safety and monitoring components on hand from the start. The B-Vent or L-Vent configuration makes installation straightforward in homes that already have compatible venting infrastructure. The supply pipe connection measures 3 inches and the return pipe connection measures 2.5 inches, fitting standard residential steam piping layouts. The unit operates on 120 volts, single phase. Physical dimensions are 38.875 inches in height, 27.625 inches in depth, and 21.25 inches in width. It carries ASME certification, CSA certification, and UL listing, meeting the safety and compliance standards that professionals and inspectors require on the job. Net AHRI rated steam output is 392 square feet. Controls are easy to access, making routine servicing and troubleshooting faster on the job site.
