Gas log sets and unlined chimneys?

Just did a 1920’s home that had a simple gas log set in a traditional wood-burning masonry fireplace. The damper was blocked from closing completely. The chimney was unlined and appeared to be in good shape albeit needed cleaning (very limited view though).


The gas furnace vented through a separate smaller unlined masonry chimney in poor condition.

So...I know the furnace chimney needs a liner, but what are the feelings about log-sets? My thought is that with the relative infrequency of use, the hotter gases (no heat-exchanger), and the fact that any rubble would be obvious, that this isn't a real problem or safety hazard. Am I wrong?

Aha…


I just found the answer to my own question over at one of those other sites.

According to Dale W. Feb, of the Fireplace Investigation, Research & Education Service,...a liner is NOT required for a log-set.

Can't get a better source than that!
