In a wood stove installation what do the terms "single wall connector" and "double wall connector" mean?

Answer 1

A single wall is used to vent, such as a space heater, hot water tank, cook stove,etc. A double wall has a vent pipe inside a vent pipe. The space between each pipe (about half an inch) will help prevent the outer surface from getting as hot as the inside.Triple wall is also available. Put stack at least 2 feet above roof with a weather cap to prevent rain damage. Smoke stack brushes are the best way to clean stack. About once a week depending on use, to keep creosote from catching on fire in smoke stack. Good Luck and BE SAFE!

Answer 2

Single wall connector refers to the thickness of pipe that you use. Single wall uses one layer and is not a good idea for venting as most codes forbid it. Double wall or B vent is a better choice and is safer, the double wall connector fastens the pipe together. I would step up to A vent or triple layer if you can swing it for safety's sake. There is less heat transfer to the outside of the pipe.

Answer 3

Your wood stove manufacturer is one source for proper chimney installations, as well as your local fire codes. Air or solid insulation materials are used in the sidewalls of chimney flue sections that pass close to flammable materials and to keep the flue gases from condensing and forming creosote as they cool passing to the chimney cap. Metal flues for conventional gas and oil fired burners also use double walled insulated pipe for the same reasons. However, the newer "condensing" gas burners use 3 or 4 inch single wall PVC flue vent pipes because the flue gases are designed to be cooled and condense water vapor.

Answer 4

I believe this refers to the "chimney" In most localities double walled chimneys are required if you are using metal ducting.
