Hi everyone! My husband and I purchased a home 2 years ago with a pellet stove in it. It's in great condition and looks to be an Enviro EF3 - we only used it a few times and we're trying to sell it this Fall because it's not very toddler friendly. Is there any way I can find out what year the model is? Any insight on how much to sell it for? It is in great condition and looks like it was sold for $3500 new. I've attached a photo. We're not very knowledgeable about this stuff, so hoping someone here can help. Thank you!
