I just got an old house and would like to keep the Sierra T4500 insert working.
I need to replace the fans as well as the ash container. I suppose the rusted ash container can be manufactured if needed with some steel and welding.
On the other hand I am not sure how to replace the fans. There are two of them. If you have any information on it please share.
I really love the insert I will be glad if I can keep it.

First off how is it installed? If it is just slid into the fireplace as these usually were originally that just isn't safe you need a liner hooked to it
 
Here are few pictures.
Two fans are just inserted on both sides of the fireplace.
As I know almost nothing about this please be more specific about what liners, etc.
If you know if there is anything on the market that can be used as a replacement for the fans please let me know.

Thank you for your help.

Pull the actual fan motor out and find the model number. Chances are a simple Google search will tell you if they are still available. And if not give you a comparable option.


As far as a liner. Most inserts like yours were simply slid into a fireplace. It was found that this caused several problems. The oversized flue and lack of connection lead to excessive creosote buildup. They are very difficult to clean properly. Because of those issues chimney fires are common and severe.

To fix these problems a properly sized and insulated stainless steel liner should be attached to the stove and run out the top of the chimney
 
Thank you for all the answers. As I read and educate myself on this subject now I know what liner is:)

Few more novice questions:
1. There is no liner in my chimney. Should I even bother with the existing insert or just replace it with a new one plus proper installation of liner?
2. How do I know if there is an acid corrosion of the chimney. There are some white discolor deposits on the chimney inside the house. Is it it?
3. What is a reasonable fee to a chimney specialist for an inspection (I am in Raleigh, NC)?

Thanks again
 
1. That is a decision you would have to make. Newer stoves are more efficient and have glass doors that actually stay clean so you can see the fire. But old stoves can still work well.
2. The white staining is probably from water infiltration into the chimney somewhere. Usually the top. Acid corrosion really isn't an issue especially because you will be relining.
3. Prices vary allot by area but 200 to 300 is probably a fair guess
