Hi,

I recently purchased a used woodstove for my basement family room. I
am wondering do I need to use some type of thimble or can I just run
the approrpiate lentgh of stovepipe through the 7" diameter hole
already present in my brick chimney to access the flue? I ask becuase
I am having difficulty finding a 7" diameter thimble, they all seem to
be 6" or 8" diameter.

I am anxious to finish the installation, but of course want to be safe.
Please lend any helpful advice.

Happy New Year!
