We just moved into an older home with what I think is a Lopi fireplace insert. I don't know anything about them. I "think" it's gas since it had a dial and plug but really have no idea. I went to the Lopi website to see if I could find a user manual but no luck there. Can anyone help me out with proper use, etc.? No one has lived here for years so not sure if it even works or is safe to use. Excuse the clutter in the pics. We're still unpacking!
