counrty comfort wood stove

Can anyone tell me the pipe diameter of the Country Comfort cc300s stove? My stove is missing the adapter plate and I guess I need to have one custom made.

Thanks, and in return I would like to offer an online manual for the cc300 for anyone who needs it.

Thanks again!

I am currently looking for this manual (Country Comfort CC200), and looks like Follansbee Steel closed its doors in the beginning of 2012. I am looking to replace the fire bricks and repaint it. The manual would be helpful. Could you send or email me a copy. I am happy to reimburse costs. Thanks, Cathy
