• 4" (102 mm) max.

Chimney Installation

Horizontal Termination

For a 5x8 vent pipe, a 10"x12" (254 mm x 305 mm) opening is required.

Vertical Termination

Stud-To-Stud Wood Framing

Diagram illustrating wood framing with steel studs, non-combustible board, and a metal header. Wood studs are shown with a non-combustible back wall and metal header.

NOTE: Dimension “Y” assumes the fireplace legs are set to a default height of 2", placing the glass opening at 4" above the floor. This “Y” dimension can change based on the client's desired viewing window height.

*All framing and finishing must be secured to the project's back wall, ceiling, or floor and must never bear weight on the fireplace. For more information, reference the Installation Manual.
