cracks in firebrick?????

PostBy: Jack Magnum On: Wed Feb 18, 2009 3:42 am

I have a TLC-2000 Harman and on my first heating season. I had it down for a day to clean it and noticed a few of my firebricks have big cracks in them . Is this normal ? How or why did this happen ?

Bricks will crack on occasion. As long as they stay in place it's fine. If they fall apart then replace 'em. Sometimes they'll go for years. Of course feel free to replace broken ones if you desire. Lot's of people will go over their stove during yearly super clean & replace them then. They are called stove bricks, half bricks, or split bricks.

While they are probably fine Jack, for the few bucks it will cost to replace them, I would do that b4 relighting next Fall. Just for Peace of Mind.

Edit: & if you haven't added another layer of bricks on top of the originals, I would do that too. (Makes top loading easier & gives you a deeper coal bed)

Also a quick fix is to get some fireplace mortar that comes in tube and can be applied with a calking gun. Shoot it in the joints and put the brick back together and let it cure with a low fire. It's a good fix if getting the new bricks in is at all difficult. holds up pretty well too.

Yep Fireplace mortor does it. I used this method before I stocked up on extra bricks. They are cheap, locally 5 for $10. I cracked alot of them in my FireplaceXtrordinaire, but just on the left side of the firebox. I figured out why, last year; I throw the wood in from the right door, and sometimes the logs hit the left side firebricks. Ooops!

Not that it matters but we also call them Pony Bricks. I have no idea why but thats what we call them on our jobs.
