Hi everyone, Just noticed my first crack in one of the stones of my Manny. On the lower center left side stone. Long hairline crack the runs both down the stone and across the stone, with a very small notch out of the stone where the two lines meet. Weeping some creosote. I know this is common and won't effect the stoves performance (per the Hearthstone statements), but wasn't fun to see any way. This is year three of full time burning with the stove. Cheers!
