Slant fin intrepid TR 30 boiler

LPM

Slant fin steam boiler piping to manufacture specifications have a TR 30 boiler was piped with 2" header and 1"1/4 Hartford loop
I had surging and priming problems boiler was flooding
I read the slant fin TR 30 installation manual
And piped to manufacture specifications
3" steam header and 1"1/2 Hartford loop
Flushed and skim no more problems boiler working great
When talked to slant fin Rep (Perry)
I was told that good no more problems
But the header should be 2"1/2 and the Hartford loop 2"
Look at slant fin piping installation manual
It shows 3" header and 1"1/2 loop
I was told it could be a misprint
And would get back to me
If it's is an error shame on slant fin

Is this gas or oil? They have different specs depending. I always spoke to the technical support. I don't see a problem exceeding the minimum requirements; It can only help as you see.

It's Oil boiler

slant fin piping installation manual

The header has to be at least as large as the risers so with the recommended 3" riser you need AT LEAST a 3" header. I don't see how that can be wrong...they're very picky about their piping and wouldn't recommend downsizing the header from the riser. On my install of TR50s I used a 4" header. I think my HL is 2", but only because I kept and reused the original 2" iron piping. Their separate venting pdf is wrong, in that it's for the Galaxy atmospherics and not the Intrepids. I pointed it out last year...they agreed, but I see they haven't changed it. It's correct in the install manual.
