I have a traditional brick chimney which I no longer
use as I have switched to a high efficiency propane
furnace (so the smoke goes out through a small pipe).

Insulate around it as best you can and be sure to cap the top and block
the
base to prevent air from moving in or out.

What is the best way to cap the top?


Install a top damper. Google "top damper". This is a better way, I think,
because it is not permanent. If you sell the place, the new owner may want
to use the fireplace every now & then.
