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

Install your fireplace stove pipe through the wall only if you have no alternative, because the stove will burn better the longer the fireplace stays inside the hot house, as it will have a better airflow and will generate less creosote.

You should also use a “Class A” chimney tube which is rated for 2,100 degrees Fahrenheit and approved to pass through walls, as this will save your home in the event of a fire. Read on to learn how to properly install your fireplace through the wall.


  1. Determine where the chimney will go through the wall and cut a hole that corresponds to the diameter of the chimney.
  2. Insert the supplied wall thimble or a radiation shield into the hole and place it or screw it into place. Put silicone putty on the joint between the wall and the shield or thimble.
  3. Attach the required length of horizontal chimney 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 tube extension between the stove and the chimney and attached with the screws provided.
  4. Insert a vertical section of the fireplace into the bracket and fasten the top of the 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 fireplace sections as needed and fit to the wall at least every 8 feet. Align the vertical seams so that the screw holes are aligned. Screw sections together. The chimney should extend at least 3 feet beyond the roof and be at least 2 feet (0.61 m) higher than anything within 10 feet (3.05 m).
  6. Insert the rain cover over the chimney and adjust with the supplied screws.

Tips & Warnings:

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