4. Installation
This trim kit is designed for use with the Dimplex BF39DXP firebox. It can be installed to provide a finished look whether the firebox is installed with or without a mantle.
4.1. Preparing for Installation
- Ensure the firebox is securely installed in its desired location.
- Clean the area around the firebox opening to ensure a smooth surface for the trim.
4.2. Attaching the Trim Pieces
- Identify the top, bottom, and side trim pieces. The longer pieces are typically for the horizontal sections (top and bottom), and the shorter pieces for the vertical sides.
- Align the first trim piece with the edge of the firebox opening.
- Using the provided mounting hardware, secure the trim piece to the firebox flange or surrounding structure. Ensure the screws are tightened sufficiently to hold the trim firmly in place without overtightening.
- Repeat the process for the remaining three trim pieces, ensuring they meet at the corners to form a continuous frame.

Issues related to the trim kit are typically minor and can be resolved with simple adjustments:
