I just picked up a Lopi wood burning insert that someone was going to trash. The sticker only says it is an LX. After many days searching I can only find articles (EPA emissions tables) on a Lopi "Flex LX....". I this the same model? If so I'm assuming I have a catalytic stove on my hands with no remnants of the catalytic element in there. Any information and insight on this would be most helpful and appreicated. It's a good looking insert, I rewired the blower and got that working, just needs some touch up and a few bricks....and a catalytic element if in fact it needs one.
