How to install a chimney pipe in a wood-burning stove through a wall?

Install your wood stove fireplace pipe through the wall only if you have no other alternative, because the stove will burn better the longer the fireplace stays inside the hot house, as it will have a better air flow and generate less creosote. You should also use a “Class A” chimney pipe which is rated for 2,100 degrees Fahrenheit (1,148 degrees Celsius) and approved to pass through walls, as this will save your home in the event of a fire. Keep reading to learn how to properly install your fireplace through the wall.


  1. Determine where the chimney will exit the wall and cut a hole that corresponds to the diameter of the chimney.
  2. Insert the supplied wall thimble or radiation shield into the hole and clamp or screw it into place. Put silicone putty on the joint between the wall and the shield or thimble.
  3. Attach the required horizontal chimney length to the clean stand and insert it through the wall inside the house. The fireplace should extend into the room at least four inches (10.16 cm). Put the pipe extension between the stove and the chimney and attach it with the screws provided.
  4. Insert a vertical section of the fireplace into the bracket and adjust the top section to the outside of the house with a wall bracket. Keep the fireplace at least 2 inches (5.08 cm) from the wall.
  5. Add additional chimney sections as necessary and adjust to the wall at least every 8 feet (2.44 m). Align the vertical seams so that the screw holes are aligned. Screw the sections together. The chimney should extend at least 3 feet (0.91 m) beyond the roof and be at least 2 feet (0.61 m) higher than anything within 10 feet (3.05 m).
  6. Engage the rain cover on top of the chimney and tighten it with the screws provided.


Tips and warnings

  • You can attach your fireplace to match the exterior of your home, but be sure to keep a 2-inch (5.08 cm) space between the fireplace and any flammable material.
  • Do not enclose the base of the clean support and do not fill the enclosure with insulation.
  • Check your fireplace at least every two months during the heating season to keep track of the creosote buildup.
