Forgive me for my ignorance, I know nothing about stoves. My husband grabbed this stove from a friend, his friend had a lot of faith in this stove but it clearly needs a lot of work. I'm trying to find a manual for this thing or some type of idea on what needs to be replaced. Or perhaps someone could tell me if refurbing this fireplace would be pointless and it'd be more cost efficient to buy new or less beaten up. Help! Please!
