1 GOLD SERIES OIL BOILERW ater with Tankless Heater | Chimney Vent | 86-295 MBH Series 3 | Efficiency 85-87%**ENERGY STAR requires a minimum of 87% AFUE, which is only achieved by these models by reducing the burner rate and installing the optional vent damper kit. See Ratings chart on next page.*APPLICATIONS INCLUDE:ResidentialLight CommercialMultiple BoilersRadiant And Much MoreHIGH EFFICIENCY CAST IRON boiler Provides space and domestic hot water heating Durable cast iron heat exchanger design Made with Weil-McLain qualityNOTES:** Add P for packaged boiler ( wtgo -3 through wtgo -6 only). Add A for boiler only ( wtgo -3 through wtgo -9).
2 (1) No. 2 fuel oil-Commercial Standard Specification CS75-56. Heating value of oil-140,000 BTU / Gal.(2) Based on standard test procedures prescribed by the United States Department of Energy at combustion condition of CO2 and " draft.(3) MBH refers to thousands of BTU per hour.(4) AHRI gross output.(5) Net AHRI ratings are based on net installed radiation adequate for the requirements of the building, including a piping and pickup allowance of for normal conditions. Provide additional allowance only for unusual piping and pickup loads. (6) Tankless heater rating is in gallons of water per minute, heated from 40oF to 140oF with 200oF boiler water temperature-tested in accordance with I-W-H Testing and Rating Standard for Indirect Tankless water Heaters Test with Boilers.
