I=B=R Ratings are determined from tests made in accordance with the I=B=R Testing and Rating Code for Baseboard Type of Radiation, including an allowance of 15% for heating effect permitted by the Code.

Ratings based on active length. Active length same as total length.

**The Hot Water Ratings at 500 lb. Flow Rate are based on a standard water flow rate of 500 lbs. per hour (one gallon per minute) through the Base-Ray. These ratings should be used for all installations except as noted under 2000 Lb. Flow Rate.

*Add ½" to length for each bushing. Add 5" to length for each valve enclosure.

***Based on ¾" pipe connections.
