HOT WATER RATINGS
BTU/HR. per linear ft. with 65˚F entering air
† Millinches per foot. *Ratings at 140˚F and lower temperatures determined by multiplying 150˚F rating by the
applicable factor specified in Table E in the I=B=R Testing and Rating Standard for Baseboard radiation.
NOTE: Ratings are for element installed as per drawing shown in “Dimensional Data” window (open “Dimensional Data” window to view) with damper open, with
expansion cradles. Ratings are based on active finned length (5" to 6" less than overall length)and include 15% heating effect factor. Ratings are also based on 3/4"
(BL-75) or 1/2" (BL-50) nominal copper tubing with 2-5/8" x 2-1/8" x .009" aluminum fins, bent to 2-19/64" x 2-1/8" or 2-5/16" x 2-1/8", spaced 56.35 per linear foot (BL-
75) or 55 per linear foot (BL-50) (unpainted). Use 4 gpm ratings only when flow is known to be equal to or greater than 4 gpm; otherwise, 1 gpm ratings must be used.
