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
*Add ½" to length for each bushing. Add 5" to length for each valve enclosure.
***Based on ¾" pipe connections.
