I am currently in the process of replacing my 30 year old Oneida 110K BTU boiler with a new Weil-McLain SGO-3 114K. The only snag I see is the old boiler has two riser pipes and the new one only has a place for one. Everything else looks pretty straight forward. Any comments or suggestions would be appreciated. I know steam heat is kinda rare these days but we heat mostly with wood and like the steam heat when we do use it. Thanks.
