Inspections needed on condensing boilers!
See attached pic, I had brought this up to a couple of the mfrs that I was concerned about this happening. Found this one today while looking over some other work customer wanted done. Smelled gas in boiler room, go figure. Ps, this is a 285 wall mount, union was tight on trap also. They need to have retainer pin or cable to keep this from happening.
