Notes:

 

 

1. The ratings are based on standard test procedures prescribed

HIGH ALTITUDE

LABEL

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 allowance of 1.15.

3. Copper-fins require special gas venting. Use only the vent materials and methods specified in the Installation and Service Manual.

4.The Copper-fin is orificed for operation up to 2000 feet altitude. The appliance will be derated 4% per 1000

feet above 2000 feet elevation. Consult the factory for

installations above 2000 feet elevation.

 

5. Ratings have been confirmed by AHRI.
