* Ratings are in accordance with standards established by The Steam Heating Equipment 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.
