Chimney cap installation

A chimney cap keeps out animals from entering the chimney and prevents sparks from shooting out the chimney and causing damage.

  1. Find out the length and width of the chimney opening. Purchase a spark arrestor chimney cap.
    It has smaller holes, letting smoke exit the chimney but preventing sparks from doing the same.
  2. Install the cap on the chimney flue. Secure the cap tightening the 4 tensions screws, but be careful not to tighten the screws too much or the flue will crack.
  3. Secure the top of the chimney cap to the body of the cap, unplugging the holes if necessary.

  • The chimney cap doesn’t remove the risk of a fire happening. The chimney still requires cleaning and inspection.
