This is my first post, but I have been lurking for a while gathering information to see if I would like to put a used smoke dragon furnace in the basement of my first home. I am looking to find a used furnace and connect to the existing ducting for my NG furnace. I have a 7x11 clay lined brick chimney that goes up the center of the house. I will put a liner in there. A 6" will be a tight fit, and using the insulation wrap will be impossible unless I get it ovalized and I am still not sure if that will work. Ovalized liners are pricey. Has anyone gotten the round liner and tried to ovalize it themselves? I heard about the pour down liners. Can a chimney balloon be used with that to stop it from filling all the way down to my old clean out. If I decide to pull the liner later, is that an option with the pour down?
The concern I have with ducting clearances is that the manuals I have read for different furnaces give different clearance requirements. Most agree on 18" the first 3 feet, 6" for 3-6 feet. Then they vary between 0 and 1" after 6 feet. All of my existing ducting is tight against combustibles. I figured I could get around the first 6 feet requirements by taking a round about path to get to the NG furnace plenum. Is the 1" of clearance beyond the 6 feet something that can be played with? I was looking at a few Yukon Jacks and WoodChucks, but they require a 1" clearance. The DAKA furnaces do not.
I have about 1300 ft1.5 story home with a full basement that has 1" foam on the block walls. It was built in the 40's and has good southern exposure once the leaves fall off the maples in the front yard. I am not considering a stove on the main floor at this time because I haven't found a way to make it work with the current floor plan and I am trying to get this done on a tight budget. (Ideally do the whole thing for under $2000.)
Thanks,
Glenn
