Hello folks, I spent so much time on here this winter it seems strange to not. Thanks to everyone who offered suggestions this winter. I have my chase opened up, my hearth installed up to the cement board and a new outlet installed for the blower on the stove. My wife picked out and we purchased tile for the hearth. I have my chimney quote from Dunamite buys (http://www.dynamitebuys.com/) I did decide to keep the chimney on the inside of the chase. I was very happy when I opened up the chase - I forgot that we insulated, drywalled and firetaped the chase so that made it a lot easier to move forward. Charlie at Blaze King suggested this http://www.condar.com/asv_instructions_english.html which I ordered yesterday. I will install it where the pipe from my gas fireplace was originally. I will post pics when it looks like something and I start on the chimney install.
