Greetings all. I recently purchased a log home with a wood stove. Grizzly 2LEX with catalyst by Derco, which appears to be discontinued. Probably installed around 1994. Anyone know what reputation these have? I'm totally new to wood stoves and trying to learn. Thinking of replacing it with something more modern but understand the EPA may have tweaked things since then. Still want to stick with a stove, however. Your wisdom appreciated. Thanks!
