Bob, I just put in a Regency Medium Insert (wood) a month ago! So far so good!! The POS zero-clearence fireplace was just that, a POS. Anything was an improvement & now I'm heating up 2K sq/ft of the house pretty well. http://www.regency-fire.com/pages/wiml.html
I think I need some gravity vents now, do you have any of those?
Has anyone seen that Chimney Sweep Log CSL? Whats the scoop on that?
