We've finally finished a plan for the boiler install. These are two stage-fired Slantfin Intrepid TR50s paired with two Riello #G400 series .#C8554115 I'm looking for any feedback concerning the feasibility of this schematic and any changes or problems those experienced with their install can see.
This is for a two-pipe Trane VaporVacuum system. The thinking with this layout is as follows: with this design there is still only one steam main leading up to
the house supply. It allows us to have the two boilers close together
with the fronts facing.outwards and gives exactly identical
piping over to the main steam line. We shouldn't need a condensate tank
because the boiler levels will even out because each has its own
condensate return with each boiler having a Hartford loop and they are
both connected together through the condensate return and the level in
the condensate will even out in the two boilers.This will ensure
the system is a closed one allowing a vacuum to be pulled. With this we won't need a condensate tank or two separate boiler pumps with boiler
float level switches, both which would be difficult to seal and maintain
a vacuum not to mention the increase in cost and complexity.

I hope someone replies to this. I know it's late in the heating system, but we'll be working on this over the summer. Thank you everyone for the help thus far. Colleen
