Looking for any reviews on these models.I have been told these are the same units.Anyone have any input to how well these units operate.I have a 1500sqft ranch home in Wisconsin.I am removing the original superior fireplace (only there for looks) and want to install a HighEfficient Fireplace.The dealers near me carry the Lennox line and Osburn line.Was told the Lennox line works well.Osburn line has no complaints.Any advice would be appreciated.
