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 2000 lb. Flow Rate are limited to installations where the water flow rate through the Base-Ray is greater than 2000 lbs. per hour (four gallons per minute). Where the water flow rate through the Base-Ray is not known, the rating at the standard flow rate of 500 lbs. per hour must be used.

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

***Based on ¾" pipe connections.

9A Base-Ray Water Content - 2.5 lbs. or .3 gal. per linear ft.
