How to Install a Flue Pipe
A flue pipe is a metal pipe that lines the inside of a chimney, and sometimes it is a stand alone pipe that carries smoke or toxic fumes out of the home fireplace or stove. Most flue pipes are single strength and made out of galvanized metal sheets to ensure that the sheets do not rust. Hot gases emitted from the fireplace have a corrosive effect that degrades the galvanized coating after time.
Tools:
- Screw driver
- Sheet Metal Screws
- Replacement pipe
- Tape measure
- Pipe Crimper
- Allow the flue to cool thoroughly and be sure there is not a fire in the stove or fireplace.
- Determine the section of the pipe that you want to replace. Each of the sections of the flue pipe is attached to the other sections on its ends using sheet metal screws.
- Locate the screws on the section of the flue pipe that you want to replace, loosen them and remove them carefully using the right size of screwdriver. Make sure that you keep them in a safe place so that you do not lose them in case you may need to use them again.
- Slide the section of the flue pipe that you want to replace by twisting it back and forth to remove it from the other sections.
- Measure the length of this section that you have removed and cut out a replacement piece from another flue pipe, which equals this length.
- Crimp the end of the replacement section with a pipe-crimper and slide it over the end to crimp the pipe until it holds together. Repeat this crimping process until the entire end of the replacement section is thoroughly crimped.
- Slide this new section into the remaining sections of the pipe so that the overlapping is about one and a quarter inches. Then, fasten with sheet metal screws and tighten.
