Retro Electric Fireplace Insert

The NShi 40 inch electric fireplace insert fits into an existing opening to replace a traditional wood or gas fire. It suits homeowners who want realistic flame visuals and supplemental heat without venting, gas lines or ash cleanup. The unit operates on standard 120V AC power and includes a six foot cable for a nearby outlet.

Recessed Installation & Common Issues

Slide the insert into a rough opening of roughly 37 to 37.2 inches wide, 8.86 to 9.06 inches deep and 26.6 to 26.8 inches high, then secure the flange against the surround. The front top vent blows warm air into the room, so keep the grille clear of curtains or furniture. A built-in overheat cut-off shuts the heater off if airflow is blocked, which is the most frequent cause of unexpected shutdowns.

Heat Output Decision Factor

Two heater settings deliver 750W or 1500W, equivalent to 5000 BTU, and are rated for spaces up to 400 square feet. If the area you need to warm is larger than that, this insert will not provide enough supplemental heat.

Questions about this item

How do I confirm the 40-inch insert is heating correctly after installation?

Set the heater to 750W or 1500W and feel warm air from the front top vent; the unit should raise the temperature in a room up to 400 sq ft. The auto-heat kill safety protection will activate if the unit overheats.

What comes in the box and what must I supply for the 40-inch recessed electric fireplace?

The box includes the 40-inch fireplace insert with resin logs, ember bed, three-sided brick interior, built-in speaker for crackling sound, and a remote control with timer. You must provide a 120V AC outlet within reach of the 6ft power cable.

Which heating setting should I choose between 750W and 1500W for the 40-inch insert?

Use 750W for gentle supplemental warmth in smaller spaces or milder weather; switch to 1500W for maximum heat output in rooms up to 400 sq ft. Both settings can run independently of the flame effect for year-round use.
