  • Steam main vent sizing

    Currently have a 2" main x 40 ft with one Hofmann #77 and one Hofmann #75. Is this adequate? Other main is 2" x 36 ft with one Hofmann #75 and one Hofmann #35. Is this adequate? If not, please recommend proper Gorton sizes. Thanks
  • Not Hofmann

    These are Vent-Rite, not Hofmann vents. My error.
