Installation and Fit
The TrueFlame 150 3DX is intended for a framed, built-in installation. It comes in a single-sided configuration with conversion components for left- or right-corner and three-sided layouts. At approximately 11 1/4 inches deep, it requires more wall depth than a slim electric fireplace.
Confirm framing dimensions, electrical requirements, clearances, and finish materials using the current cut sheet before construction begins. Professional installation is recommended.
