A clean edge around the gathering.
BF4TRIM39 finishes the perimeter of BF39DXP / BF39STP with a four-piece metal frame. It creates a defined transition between the appliance and the surrounding wall or mantel while the firebox remains a separate part of the installation.
The exact model drawing shows an assembled width of 42¼ inches, height of 33¾ inches and depth of 1¼ inches. Check that finished footprint against the appliance position and surrounding wall rather than treating the nominal firebox size as the frame’s outside width.
Complete the firebox’s support, power and clearance planning first. The trim finishes the installation; it does not replace those requirements.
Measure the finish. Match the firebox.
Use the assembled frame measurements below for finish planning. Use the exact firebox guide for rough framing, support and installation clearances.

Let’s get your project right.
Does the number in the trim model mean its outside width?
No. BF4TRIM39 identifies the trim for BF39DXP / BF39STP. The annotated drawing gives an assembled outer width of 42¼ inches and height of 33¾ inches, with 1¼ inches of depth shown. The appliance name, trim outside dimensions and framed opening are separate measurements.
Which dimensions should my installer use for the fireplace opening?
Use the exact firebox’s framing instructions for the opening and support. The trim drawing describes the assembled finishing frame; it does not establish an alternate rough opening or reduce the firebox’s clearance requirements. Compare the completed wall and appliance position before choosing the trim.
Can I use the same frame on another BF size?
BF4TRIM39 is documented for BF39DXP / BF39STP. The other trim choices grouped on this page belong to different firebox sizes, rather than pieces that combine to make a larger surround. Match the full firebox model, not a similar overall appearance.
Is this a single panel or a four-piece frame?
The manufacturer identifies the product as a four-piece installation trim. The pieces finish the perimeter of the documented firebox. It is not an electric heater, a front glass door or the complete firebox; those parts have separate product identities.
Can this take the place of a glass door?
No. A perimeter trim and a glass-door accessory serve different roles. The exact BF39STP specification lists the BF4TRIM39 frame separately from its glass and door alternatives. Choose each item according to the selected firebox and installation rather than assuming the trim closes the front with glass.
Will it support the appliance or correct an oversized opening?
The trim is a finishing accessory. It does not provide the firebox’s structural support or make an unsuitable opening compliant with its installation requirements. Resolve the opening, support and surrounding materials using the firebox guide, then check the assembled trim’s coverage.
Should I buy all three trim options for one fireplace?
No. The model options are alternatives for different BF firebox sizes. Select the exact accessory that belongs to the appliance you have; the options are not additional border sections to order together.
What should I measure on an existing surround?
Record the full firebox model, the opening, the appliance’s finished position and the area available for the outside frame. Compare that with the annotated drawing rather than using the nominal fireplace width as the trim width. Keep the firebox’s service and control access available.
Does changing the trim affect the heater or wiring?
The finishing trim does not establish a new heat output or electrical connection. Follow the BF appliance’s own voltage, wiring and control instructions, and allow the appliance to cool and be safely disconnected before installation work. A decorative frame is not a power-conversion accessory.
What should I keep for fit and accessory support?
Keep BF4TRIM39, the firebox’s complete model number, the measured opening and finish details, and your purchase record. The documents below identify the related system. The separate trim does not automatically inherit the appliance’s electrical-component warranty period.
CONFIDENCE BEYOND THE FIRST FIRE
The right fit. The right support.
Keep the accessory model, complete appliance model and purchase record together for fit and support. Use the linked system resources for installation context; a separate accessory does not automatically inherit the appliance’s warranty period.
