Amantii 38" Traditional Signature Insert BI-TRD-38-SIG

Product overview

The Amantii TRD Signature is a 38-inch traditional firebox that pairs Amantii's electric flame with the Dimplex Optimyst water-vapour effect. Add the Optimyst cassette and a fine mist rises through the logs, catching the light like real flames and smoke.

Its tall, classic opening suits a traditional hearth or a modern feature wall, and optional liners in black glass, used brick red, wenge brown or dark brown let you set the tone. Change the flame from yellow to orange to red with a click, and let the ember bed glow beneath the logs.

Comfort and sound come built in. The heater holds the temperature you set, two speakers add a gentle crackle or stream your music over Bluetooth, and the remote or app puts it all at your fingertips. No gas, no venting and no emissions.

Key features

• Traditional firebox look. A tall 38-inch opening with a classic hearth shape for a true fireplace feel.
• Optimyst flame effect. A Dimplex Optimyst cassette uses ultrasonic mist to create realistic flames and smoke; Amantii recommends one for this model.
• Electric flame on its own. The Amantii LED flame works without the cassette, so you can enjoy the fire either way.
• Flame color at a click. Switch between yellow, orange and red flames, each with adjustable brightness.
• Ember and canopy lighting. The ember bed mixes red, green and blue light, and the canopy light offers 10 colors plus a cycling mode.
• Fire and sound. Two speakers play a crackling fire sound you can switch on or off in the app.
• Bluetooth audio. Stream music from your phone through the built-in speakers.
• WiFi app control. Control flames, heat and sound from your phone with the TuyaSmart app.
• Thermostatic remote included. A color remote sets flames, temperature and timer from across the room.
• Heat when you want it. A fan heater with a 59–83°F thermostat, rated 1,500 W at 120 V or 3,000 W when hardwired for 240 V.
• Timer and weekly program. Set an off timer from 30 minutes to 8 hours, or program daily on and off times for the week.
• Optional liners. Four liner finishes let you change the look of the firebox.
• Zero emissions. No fuel, no venting and nothing released into the room.

Installation and safety notes

Frame the opening to 38 1/4" W × 38 5/8" H × 20 7/8" D and leave at least 1/4 inch (6 mm) around the appliance. Keep furniture, curtains, bedding and other combustibles at least 3 feet (0.91 m) from the front, sides and rear. Let the unit reach room temperature before the first use if it has been stored in the cold.

Provide a 20-amp, 120-volt grounded branch circuit, ideally dedicated. A qualified electrician can hardwire the fireplace for 120 or 240 volts, grounded to local code. Never use an extension cord, and never run the cord under carpets or rugs.

The Optimyst cassette is wired into the fireplace harness with at least 14-gauge wire and fed by a water line. Openings in the bottom of the unit can carry the water and power lines. Do not slide the cassette too far forward, or it can touch the flicker assembly.

Amantii approves the TRD Signature for outdoor use in a protected location. Outdoors, the fireplace must be in an area protected from direct water, on the exterior of a main building and never in a standalone structure. Build an overhang to the front and to each side that extends at least half the roof-line height, measured from the base of the fireplace. For example, an 8-ft roof line needs a 4-ft overhang. The fireplace is designed to run in temperatures from 41°F to 95°F (5–35°C).
