Hi everyone. I’m hoping for a little guide and help here. I’m converting from oil to gas. I passed inspections on my gas line and also new chimney liner... now that I have the gas inside, I am trying to finish my new boiler. I will post pics of the recent progress of the boiler. Hoping for someone to tell me what’s left in completion.
So, due to the way i had to come out the chimney to the damper, I had to cut some of the copper pipes...
question 1: boiler comes with a water cut off 24vdc but I have a hydrolevel water feeder vxt-120.. how do I go about wiring these two together, or do I need to get a vxt24.

Question 2: do I need a water expansion tank?

Question 3: from the pics, is there anything else missing that you notice, to finish boiler?
I know I have to install two drain valves on each side of boiler

Question 4: can I connect the circulator direct to the shutoff switch power? And also, does anyone know got the heck to undue a 3” Flange stuck on a piece of black pipe!? Lol

    Forgive me, sir or madam, but you are asking some incredibly basic questions for someone who is trying to install a steam boiler, and I have to wonder if you are not, perhaps, in way over your head.

    You would be very wise to acquire the book The Lost Are of Steam Heating from this site and study it. Then also study the boiler manufacturer's piping diagrams for the near boiler piping (I see at least one serious error on a quick glance).

    And no, on a steam heating system you do not need an expansion tank...

    But you do need to use components designed for an open system on that condensate hot water loop if i'm not mistaken

    @mattmia2 thank you for your insight. I am the homeowner and yes it’s my first time installing a boiler(replacing an oil one to a gas one with original piping), but I’m pretty savy with piping, low voltage and electrical wiring. Also, I am checking out that book now. And it’s actually really interesting!
    What serious error did you see from the pics?
