Question: Olympic Crest Wood Stove Happy Holidays!! I own the above stove and am in search of the transition collar that comes off the top of the stove and connects to an 8" stove pipe. Can you help?????????? Answer: We usually just ovalize 8" stove pipe for such jobs, but you might be able to use a part made my Vermont Castings for a similar stove. It's part #1855 and should be available at your local Vermont Castings dealer.
