In Reply to: Cleaver Brooks rear door hole posted by Angus on February 02, 2007 at 03:15:39:
: I have 3 Cleaver Brooks 700hp boilers.
: Model # CB100-700-150
: I've noticed some combustion gas leaking out of the bottom of the rear door on one of them. We found a small bored hole at the very bottom of the door approx 1/4 in diameter. The other two have this as well but are not leaking any gas. I've never noticed these before and am wondering what they are for. Maybe cheater holes?
The leak is most likely from a warped rear head causing the outer door gasket to leak. Or just a bad gasket.
