I recently purchased a house and it has a stove. I grew up with a very old stove in my early years but I have never had to buy parts for one. It is a Sierra 7000 cat stove that wasn't loved by the previous owners. I inspected the stove after moving in and started by cleaning it. all of the bricks were cracked inside so i started by taking them out and ordered new ones. I then went on with cleaning it out the best i could so i could get a good look at it to make sure it was in working order and found the gaskets were all beat up pretty bad so i have them taken out. Then I had to clean out several inches of candle wax from the ash pan. for the life of me I could not find the cat so after some research I have found that the entire assembly was removed. I can not find a replacement as the stove is no longer manufactured. There is no parts diagram that i have been able to locate. The newer 8000tec is similar and still made. I have found that some of the features were unchanged however one thing that did change was the cat and the holder for it. after spending a good deal of time on the phone with the current manufacturer the new one have something like a 16 in gap between the two bolts that secure the holder and mine has a 13 inch gap. A little bit lost as for how to proceed. no one seems to sell any parts for the stove that I need and I don't know where to go from here. I love the features on this thing and my understanding is that it is a pretty good stove.
