It's a small boiler about 23 x 28" x 36" tall on 2" thick blocks, in a low basement(65"). Doesn't leave much room above for a fill-trol (27" tall) and circulator pumps.
I am thinking of piping the feed line up, 25" and behind the boiler 45" to the wall then 1 foot or so to the right to leave room to service the vent. Then mount the fill-trol, circulator pumps, flow checks along the wall.
I like TGMC's and Freddy's comments, maybe a combination of both.
