How do you connect a wood stove to a chimney?

This repair is best handled by a professional, but if you can get your hands on a good quality 316 Ti alloy flexible stainless steel liner or rigid liner sections, you may be able to handle it with help from a friend. Most liners come with instructions from the manufacturer. Follow these closely. Basically, you just push the liner down the chimney from the top and then hook it up to your wood burning appliance using a tee. Make sure the liner is large enough to handle the smoke. As a general rule, the liner must be at least as large as the outlet on the appliance. For example, if you hook up 6" smoke pipe to the top or back of your stove, then you need at least a 6" liner diameter. In some instances, the existing terra cotta or vitreous clay flue tiles must be removed before you can put in the liner. And remember, too, that for any solid fuel burning appliance (coal or wood) the liner has to be insulated with a ceramic wool insulation material or pour-down masonry based insulation mix. Probably best just to call a pro.

If you are prepared to do it yourself, it can be easy, depending on the height, steepness of your roof, etc..., shop the internet well, there are a very few quality, reputable, fair priced companies out there, make sure of warranty, and type of liner, based on the ss grade, and style of liner...
