*Ratings are in accordance with standards established by The Steam Heating Manufacturers Association (SHEMA) no safety factor required.
**To convert Square Feet EDR to pounds of condensate per hour: Divide the square foot ratings by 4.
 One Square foot EDR is equivalent to net emission of 240 BTU per hour with 215°F steam in the radiator surrounded by 70°F air     temperature.
***Basic ratings for trap pressures greater than 25psi are given in lbs of condensate per hour.
 One pound of condensate is equivalent to approximately 1000 BTU, 1000 BTU is equivalent to approximately 4 square feet EDR.
