First of all thanks to all the folks questions and threads I've looked thru for an answer - unfortunately I did not find the solution as of yet. Truly there are far more creative then I and knowing this I'll do my best to explain. More than likely a couple pictures would help and I have them q'd up for that. 1st off the chase that had to be utilized is where it is and the reason for this is the bedroom above (limited to the space it has) somewhat made that decision for us. While it made that decision it didn't provide the solution to the problem we now face on the 1st floor. The Selkirk chimney is installed aft the Ceiling Connector mounted securely to the 1st floor ceiling which is/runs adjacent to the the existing brick chimney (venting the boiler and water heater in the basement) through both floors and out the roof as they do. Having to make provision for a new chimney chase and a couple of closets a stairwell to the attic was removed to make room for all three (2 closets and the new chimney chase). What was thought at one time to be a clever solution has turned into the conundrum we now face and that is that the Ceiling Connector (with the single wall stove pipe hanging down from it for eventual wood stove hook up) is far too close to the wall that the back of the wood stove will face - parallel installation. From the wall (1st floor - stove wall) the center of the 6" stove pipe exiting the bottom of the Ceiling Connector is but 9" (inches) to center. Leaving from the sheet rock/plaster&lathe a 6" space and that is that. The unit/ wood stove allows with the optional rear heat shield 13" (inches) to shield and 17" to pipe and this with double walled stove pipe. Again this is a conundrum to us. Any insight you may have or oversight that we've made thus far pointed out is much appreciated. Directly behind the wall of where the unit is placed in the parallel mock-up picture is the old bricked chimney. So at that point the wall has but plaster and lathe and a layer of 1/2 sheet rock now covering it a total of no more than 1 inch to gain. The wood stove room is relatively small as well and so the the tighter to the wall the better.
