Throat Question

[Jerry Simon]

Masonry fireplace with a throat constructed of pieces of clay flue tile. Is that okay? If not, why not?

[kurt]

No, it's not a continuous liner. Cinders get caught in the gaps between the pieces of tile.

Or maybe not. Hard to tell without a pic.

irc section 10 does not list flue tile

Masonry fireplaces shall be constructed of solid masonry units, hollow masonry units grouted solid, stone or reinforced concrete. When a lining of firebrick at least 2 inches (51 mm) in thickness or other approved lining is provided, the total minimum thickness of back and side walls shall be 8 inches (203 mm) of solid masonry, including the lining.

The width of joints between firebricks shall not be greater than 1/4 inch (6.4 mm). When no lining is provided, the total minimum thickness of back and side walls shall be 10 inches (254 mm) of solid masonry. Firebrick shall conform to ASTM C 27 or C 1261 and shall be laid with medium-duty refractory mortar conforming to ASTM C 199.

Thanks, Barry 2006

Since I've never seen such in 23 years doing this, I figure it wasn't *right*. Now up to the Level II folk. I will be following up with client to see what Level II folk say.
