Notes

1. Based on standard test procedures prescribed by the United States Department of Energy.

2. Net I=B=R ratings are based on net installed radiation of sufficient quantity for the requirements of the

building and nothing need be added for normal piping and pickup. Ratings are based on a piping and pickup

factory of 1.15. An Additional allowance should be made for unusual piping and pickup loads.

AHE boilers tested at 50 PSI working pressure.
