(1) 1000 Btu/hr (British Thermal Units Per Hour)
(2) Heating Capacity and AFUE (Annual Fuel Utilization Efficiency) are based on DOE (Department of Energy) test procedures.
(3) Net AHRI Ratings based on piping and pickup allowance of 1.15. Contact Technical Support before selecting boiler for installations
having unusual piping and pickup requirements, such as intermittent system operation, extensive piping systems, etc.
*Max CH Supply temp 176° F (80°C)
