Notes:
1. Based on standard test procedures prescribed by the United States Department of Energy. Ratings also referred to as AGA/
CGA Output.
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 allowance of 1.15. An additional
allowance should be made for unusual piping and pickup loads.
Boilers are tested for 50 lbs working pressure. GV boilers are not available for millivolt systems.
