Help me swap my Gorton #1 main vent (with free used Hoffman 75) ?

60 foot main. 2. diameter. Likely Gorton #1. Once boiler starts, it takes 10 mins to heat to the end of the main. Can't recall how long it took for steam to heat the boiler riser. Friend has spare Hoffman 75 vent he gave me.

  1. Not sure how to cut away ceiling to access old Gorton #1
  2. Not sure how much I need to cut away to fit large wrench horizontally with ceiling.
  3. Can I hand tighten the Hoffman 75? Or does it need to be snugged down with wrench? Tight space to fit huge wrench
  4. What wrench do you guys use for this? Pipe wrench is too wide to access nut.
  5. Does Gorton #1 and Hoffman #75 have same thread size? Direct swap?
