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?
