† 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.
With 65˚F entering air.
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 o verall length)and include 15% heating effect factor.
Ratings are also based on:
81-A: 3/4" nominal copper tubing with 3" x 3-1/4' x .024" alumin um fins spaced 48 per linear foot (unpainted);
83-A2: 3/4" nominal copper tubing with 2-3/4" x 2-1/2" x .011" alumin um fins spaced 55 per linear foot (unpainted);
84-A3: 1" nominal copper tubing with 3" x 2-1/2" x .011" alumin um fins spaced 48 per linear foot (unpainted);
85-AX: 1-1/4" nominal copper tubing with 3" x 3-1/4" x .020" alumin um fins spaced 48 per linear f oot (unpainted);
86-AX: 1-1/4" IPS steel with 3" x 3-1/4" x .028" aluminiz ed steel fins spaced 48 per linear foot (unpainted);
Use 4 gpm ratings only when flow is known to be equal to or g reater than 4 gpm; otherwise, 1 gpm ratings must be used.
