Broken Chimney Tiles

I have some broken chimney tiles in the chimney I want to exhaust a coal stove out of. Does this matter? My understanding is the tiles are to contain chimney fires which should not happen with a coal stove (unlike wood).

The tile is there because of its high temperature resistance, yes. Without inspecting the chimney personally, it would be difficult to answer. If it has a good draft and the tile damage is minor, you can probably use it. A local chimney sweep (dirty guy in top hat :) ) could probably answer that question. The first thing to look for is, are any tiles loose or badly cracked? This would indicate a problem that may continue and needs to be addressed if you plan to use it safely. A piece of tile could break out and possibly block your flue while you are operating your unit. Water is the usual suspect in a lot of these cases. It gets into cracks and then freezes, taking your chimney apart a little at a time. This is why it is so important to keep the top and exterior of your chimney sealed and pointed up. Another factor would be its construction. It may have been assembled improperly and or has all or a portion done with substandard materials. More than likely, the chimney is sound and can be used with or without some minor repairs. Have someone that knows what they are doing look at it prior to using it.
