I'm going to see a used insert that looked like a Lopi in the picture. Looking for a woodstove and this one LOOKS like a Lopi Revere but I am not sure. Would I be able to easily tell if this insert was instead intended for Pellets? Do the pellet stoves all have the line of circular holes above the door? If it is a pellet stove, I might actually buy it anyway and give it a try cause the price is right! But I am not sure how to tell the difference if there is no tag on the back, lol!
