(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.
