Old CEMI wood burning fireplace insert - any info appreciated

Hello! The house I purchased a couple of years ago came with an old CEMI insert. I've recently had my chimney replaced and I'd love to get this old stove going again. The blower works and all parts appear to be functional. It doesn't look like it was used much, if at all. My next step is to purchase a chimney liner and I have to get some measurements from it to order the parts.

I've been trying to find a manual or any information whatsoever about this insert online and I'm coming up blank. I'm hoping someone here might recognize it and give me a few more details, such as a model number. I have found info on the CEMI Concept II - I believe this stove pre-dates that version.

Thanks very much.

 

What size is the connection for the stack?

It looks like it's a slammer, which if that's the case, you won't want to use it.

 

Wow...great doors on that...looks like the doors to a dungeon.
