How to Upgrade an Old Brick Chimney for Wood Burning Stove

Ensure that your old chimney is constructed of masonry with an open clay liner and is not sealed off. If your home is older, you might find more than one flue in your masonry chimney, but you only need one. These old chimneys were practical when you needed several fireplace chimneys, wood stoves or cook stoves in one house. If you suspect the chimney is old but doesn't leak, you would be safe to install a steel liner partially up the flue for your wood stove exhaust.

Instructions

- 1
  Clean out your chimney with the help of a chimney professional. This will remove any old carbon or creosote buildup left behind from the fireplace use.
- 2
  Measure at least a 3-foot section of the chimney liner for installing in your chimney. This will be long enough to create a draft for pulling air across the fire and pulling out the smoke. The smaller diameter of the liner will also help prevent creosote buildup.
- 3
  Push the liner up into the chimney opening, passing the damper area, leaving part hanging through the opening. Using self-tapping screws, screw the base of the liner to the end of the pipe that goes into the back of your wood stove.
- 4
  Connect the pipe to the back of your wood stove by sliding the sections together and screwing in a couple of self-tapping metal screws to hold the sections secure. Fire up the stove according to the manufacturer’s directions. The smaller section of chimney lining will help pull the smoke away and into the chimney.
