Weil-mclain 672619219427 Sgotm Series 4 Steam Oil Boiler 114 Mbh Cast Iron Heat Exchanger 85% Afue Burner Sold Separately

Product Description

The Weil-McLain 672619219427 is a residential oil-fired steam boiler built for reliable, long-term heating performance. Part of the SGOTM Series 4 collection, this floor-mounted unit features a cast iron heat exchanger that holds up to the demands of daily heating cycles in residential applications. Cast iron construction is a proven choice for steam boilers because it retains heat well, resists corrosion, and delivers consistent steaming times over many years of service. The boiler carries an AFUE rating of 84 percent, meaning it converts a high percentage of fuel into usable heat, helping homeowners manage energy costs through cold seasons. With an input rating of 133 MBH and a net output of 114 MBH, this unit is sized for residential steam heating systems that require a dependable heat source. The large water content design supports longer steaming times, which helps maintain even, comfortable heat distribution throughout the building. Two flue outlets are located on the rear and top of the unit, giving installers complete venting flexibility to work with a variety of existing chimney and vent configurations. This is especially useful during retrofits where vent routing can be a limiting factor. The unit comes with full steam trim, including a probe-style low water cutoff, steam pressure gauge, gauge glass, cocks, and guard. A barometric damper and a swing-away burner mounting door are also included. The burner is sold separately, and compatible options include Carlin, Beckett, and Aiello burners, giving HVAC professionals the flexibility to match the burner to the specific job requirements. The unit is ASME certified, CSA certified, and UL Listed. It operates on 120V single-phase power with a natural draft vent system and an intermittent spark ignition system. The supply pipe connection is 2.5 inches and the return pipe connection is 2 inches. Overall dimensions are approximately 16.875 inches deep, 35.625 inches tall, and 20.25 inches wide. Introduced in an updated Slate Gray color in 2021, this boiler is a solid choice for residential steam heating installations and replacements.
