Identify the part. Match the model.
The BF45DXP service table identifies 5900160400RP as the partially reflective glass panel at callout 12. Match that part number to the complete fireplace model before arranging a replacement.
The internal reflective panel is separate from a front-glass accessory, swing door or decorative finishing trim. Those parts perform different roles and should not be selected as substitutes for a damaged reflective panel.
The manufacturer service diagram is provided to help identify the selected component. It shows the surrounding appliance for reference; the purchase is the replacement panel only.
The right fit starts with the exact model.

Let’s get your project right.
Is this the outside front-glass panel?
No. The manufacturer parts table identifies 5900160400RP as partially reflective glass for the internal panel position, callout 12. It is separate from front-glass and door accessories.
Which BF45 model is documented?
The accepted service table identifies BF45DXP and its exact replacement panel code. Match the full appliance model rather than assuming any 45-inch Dimplex firebox uses the same glass.
Can I use a panel listed for BF33 or BF39 instead?
No fit substitution is established. The manufacturer table gives different partially reflective glass codes for the BF33, BF39 and BF45 columns. Match the BF45DXP row and part number.
Why is there a full fireplace in the technical image?
The manufacturer exploded diagram locates the panel within the appliance. Callout 12 identifies the relevant component; the full fireplace and the other numbered parts are not included in this service-part purchase.
Can I replace this with ordinary cut glass?
A similar physical size does not establish the required reflective properties, mounting or appliance suitability. Use the specified replacement part rather than choosing only by approximate panel dimensions.
Does this panel alter the heater output?
No new electrical or heating rating is established by replacing the reflective panel. The appliance remains governed by its own installation and operating requirements.
Will it repair every flame-display problem?
No. The service guide distinguishes the panel from lamps, the reflector mechanism, motor and control components. The actual fault should be diagnosed before selecting a replacement.
Are mounting brackets or other hardware guaranteed in the package?
The accepted manufacturer parts table identifies the selected panel but does not establish a complete hardware packing list. Do not assume that unrelated brackets, doors or trim are supplied with it.
Is replacement a normal front-access cleaning task?
The internal panel is a service component. Use the exact manufacturer service procedure and a qualified technician rather than treating it as an external decorative panel.
What details should I provide for a replacement request?
Keep the BF45DXP model/serial record, the 5900160400RP part code and a description of the diagnosed damage available. These identify the service part without relying on a generic “back glass” description.
CONFIDENCE BEYOND THE FIRST FIRE
The right fit. The right support.
Keep the exact accessory code, appliance model and purchase record together for replacement-part and fit support. This separate accessory does not automatically inherit the fireplace’s warranty period.
