Follow this step-by-step guide to safely mount your DREO Smart Wall-mounted Heater 517AS with ALCI plug. Includes tips on wall placement, wiring, and testing the safety plug.

Quick answer

Mount the DREO 517AS securely to a wall stud, plug it into a grounded outlet, and test the ALCI safety plug before first use.

Why wall mounting matters for the 517AS

Unlike portable space heaters, the DREO 517AS is designed to be mounted on a wall. This keeps it off the floor, reduces tripping hazards, and allows you to direct heat exactly where you need it—especially useful in bathrooms or tight hallways. However, incorrect mounting can lead to instability or poor air circulation, so following the steps below is critical.

What to know about the ALCI plug

The ALCI (Appliance Leakage Current Interrupter) plug is a built-in safety device that cuts power if it detects a ground fault—similar to a GFCI outlet. It is especially important in rooms with moisture, such as bathrooms. The plug has Test and Reset buttons; you must test it before each use to ensure it functions properly.

Installation steps for DREO 517AS

Choose the mounting location: Select a wall location at least 6 inches from the ceiling and 12 inches from any side wall or furniture. Ensure there is a standard 120V outlet within reach of the power cord. Avoid mounting directly above a bathtub or sink. Common mistake: Mounting too close to the ceiling or corners restricts airflow and reduces heating efficiency.
Mark and drill pilot holes: Hold the mounting bracket against the wall and mark the screw locations through the bracket slots. Use a level to ensure the bracket is straight. Drill pilot holes into wall studs—drywall anchors alone may not support the heater's weight. Checkpoint: Use a stud finder to locate solid wood or metal studs before drilling.
Secure the mounting bracket: Attach the bracket to the wall using the supplied screws and anchors. Tighten until the bracket is flush against the wall. Do not overtighten, as this can strip the holes or damage the bracket. Common mistake: Using anchors in drywall without a stud—the heater may pull loose over time.
Hang the heater and connect power: Align the heater's rear slots with the tabs on the bracket and slide downward until it clicks into place. Plug the ALCI cord into a grounded 120V outlet. The plug fits standard US receptacles. Checkpoint: Ensure the heater is fully seated on the bracket—listen for the click. A loose mount can cause instability.
Test the ALCI safety plug: Press the Test button on the ALCI plug. The power indicator should turn off. Then press the Reset button. The indicator should turn back on. If it does not, unplug the heater and do not use it—contact DREO support. Common mistake: Skipping the test before each use. A faulty ALCI plug may not protect against ground faults.
Set up smart features via the DREO app: Download the DREO Home app, create an account, and follow the in-app pairing instructions to connect the heater to your Wi-Fi network. Once paired, you can adjust ECO mode, set schedules, and control the heater remotely. Checkpoint: Place the heater within Wi-Fi range of your router during initial setup to avoid pairing issues.
