Someone recently asked for this in a post. I didn't bookmark it and have looked through the regular suspects recent ones with no luck. So here it is. I used the ideas extensively in my install and found it useful in many regards. I hope others do, as well. :)

    Ur Welcome! The only thing I didn't incorporate (besides a two-staged gas valve) was the piping arrangement for multiple boilers. As shown here one can completely isolate the boilers. That's not necessary and skeeping stuff equal much harder. I did mine as SF and the pros on this site suggested.

    I added insulation between the block and jacket of my old V7 boiler and found it cut the losses a little bit.

    When I had the new G8 installed in 2012 I did the same and found it cut almost half a minute of the time it takes to raise steam to the boiler riser, that is not a lot but given the number of times a boiler fires in a season every little bit helps.

    That's what was so great about this info. It quantifies all those things we try to do ie CPH. multi-staged firing, twinning, standby and jacket losses and let's one see the ADDITIVE effect of it all. It also influenced my decision to go with a wet-based boiler.
