We didn't know, or ask, but Heatilator made a replacement kit for just this situation. Big mistake on our part.
Now, to do it again, I'd go for a fireplace insert and new stainless steel stovepipe so you don't have to re-line the chimney. Chances are, if your chimney has ceramic tile, it may not be in good condition, collecting lots of creosote.

Ours may be a similar setup. It has a steel liner and there are vents on each side of the fireplace I haven't found a fan though.
