Dimplex Deluxe 45" Built-in Electric Firebox
The Dimplex Deluxe 45" Built-in Electric Firebox (model BF45DXP) is the largest of the BF built-ins and the traditional end of the Dimplex range — a proper firebox shape with a brick-look interior and a log pile, meant to be built into a wall and finished with a trim or a door so that nothing about the result says "electric".
It is also the line Dimplex builds for commercial work. The glass stays cool to the touch, there is no flue and no fuel, and it meets the strictest building codes, which is why you find these in hotel lobbies, care homes and waiting rooms as often as in houses.
The Thing That Makes This Line Different: 240 V
Most electric fireplaces are a 120 V supplemental heater and nothing more. The BF series can be wired to 240 V, and at that voltage it produces 9,213 BTU — nearly double what a standard 1,500 W electric fireplace manages, and enough that Dimplex positions it as part of a primary heating plan rather than a top-up.
Decide this before your electrician roughs in. Converting later means pulling a new circuit.
Will It Fit? Rough Opening
| Framed opening width |
45" (114.3 cm) |
| Framed opening height |
32 7/8" (83.6 cm) |
| Framed opening depth |
16" (40.5 cm) |
| Firebox dimensions (W x H x D) |
44 3/4" x 32 3/4" x 15 3/8" (113.7 x 83.3 x 38.7 cm) |
| Installation height |
Floor level or mid-wall |
Note that the firebox is smaller than the opening in every direction. Unlike a linear fireplace with a built-in flange, this one drops into the hole and leaves a gap — the BF4TRIM45 trim kit or one of the door kits is what covers that gap. Budget for one of them; the firebox on its own does not finish the opening.
At 16" of framing depth this needs a purpose-built chase or a masonry opening — it will not go into any stud wall.
On the viewing area. Dimplex's sell sheet for the 45" prints a viewing width of 45 1/2", which is wider than the firebox itself at 44 3/4" and wider than the framed opening at 45". A window cannot be wider than the appliance it sits in, so that figure is wrong somewhere and we have left it off rather than repeat it. If you need the glass size for a surround, call us and we will measure a unit.
Electrical Requirements
| Voltage options |
120 V, 208 V or 240 V |
| Flame only, no heat |
245 W, 2.0 A |
| 120 V with heat |
1,440 W, 12.0 A — 4,913 BTU/h |
| 240 V with heat |
2,700 W, 11.25 A — 9,213 BTU/h |
| Connection |
Hardwired to a dedicated circuit, or the optional BFPLUGE plug kit |
Note that the heat output is the same across all three BF sizes — the 45" gives you a wider fire than the 33" or 39", not a warmer room.
Clearances
The BF series is a zero-clearance design, with one exception. From the installation manual: insulation and vapour barrier must be kept a minimum of 2" (5.1 cm) from the top of the unit, and no combustibles may be placed on the top surface of the fireplace. Everywhere else, framing can come right up to it.

Documents & Downloads
A note on the sell sheet. Dimplex's BF sell sheets label the three framing dimensions A, B and C, and the labels are transposed — the sheets print the framed opening width as though it were the depth. The figures on this page come from the installation manual and the 3-part architectural spec, which have it right. If your installer is working from the sell sheet and the numbers look odd, that is why; call us.
