Also, check your controls. When the blr is cool, light it off and blow it down to a floor drain or a couple of buckets to check that the water in the glass drops and the feeder opens if you have one, and that the low water cut off kills it. Don't go too low for too long when the boiler is too hot. The gage glass should have the bonnets removed and rod out any deposits that are built up. Also, get the blowdown fitting on the bottom of the glass working if it isn't. With that you can blow out the top and bottom fittings (one at a time at pressure). If your glass is filthy you could remove it to clean. If it's 25 or more, it might break long before it comes out.
