Who it's for

Wrong buyer. You want a built-in look; every wall or built-in line is that.
Will it fit?
Dimensions from the specification sheet
Height, width and depth of the unit, from Amantii's specification sheets. The wall opening is the unit's width and height plus the clearance in the manual linked below; where Amantii publishes the framing opening it is in the second table. Glass, surround and weight are in the specifications.
| Model | Height | Width | Depth |
|---|---|---|---|
| CUBE-2025WM-LUMINA | 25‑1/4" | 19‑5/8" | 11‑3/4" |
| CUBE-FS2025-LUMINA | 25‑1/4" | 19‑5/8" | 11‑3/4" |
Clearances
An electric fireplace has no flue and no hot firebox; its clearances are about the heater outlet and the electrical box.
| Clearance | Minimum |
|---|---|
| In front of the heater outlet, to curtains, bedding, furniture | 36" |
| Combustible mantel or shelf above the heater outlet | per the installation manual for the model, linked below |
| Sides and back, to wood framing | 0"; the units are designed to be framed in wood |
| Floor | 0"; no hearth required |
Heat and power
120 V plug-in, 1,465 W; 5,000 BTU. The flames run without heat; the heater is fan-forced from the top of the unit, so nothing shows in front of the glass.

Questions people ask
Does it need a dedicated circuit?
Yes. The heater draws around 1,500 watts on 120 volts, most of a 15-amp circuit, so give the fireplace an outlet of its own and never an extension cord. Models with a 240-volt option are hardwired by an electrician.
How much does it heat?
The heater is supplemental: it warms the room you sit in, about 400 square feet on 120 volts, not the house. The flames run without heat on a few watts.
Can it go outdoors?
Only the models Amantii rates indoor-outdoor, and only under cover, protected from rain and direct sun; check the specification sheet linked below for your size.
Can I change the media later?
Yes. The log sets, glass and media kits are separate parts and drop into the media bed; the ones sold on this page are matched to the size.
What does the app do?
On WiFi models the Amantii app controls power, flame color, brightness and speed, the heater and timers from your phone; the remote in the box does the same from the sofa.
Can I return it?
Electric fireplaces are large, glass-fronted and shipped by freight. Confirm the size and the opening with us before you order, and contact us before returning anything.
Is it hard to install?
Wall mounts and freestanding units are a plug-in job. Built-ins need a framed opening from the specification sheet and an outlet or a circuit inside it; an insert needs the old fireplace retired and an outlet in the firebox.
What is the warranty?
Amantii's limited warranty is printed with the fireplace; we will confirm the term for your model before your order ships.
