Frequently Asked Questions

  • The Trivista Primis 50-inch (NEFB50H-3SV) must be hardwired — it does not plug into a standard wall outlet. It is designed to be hardwired to either 120V or 240V, and because of this, professional electrical installation is strongly recommended. The 240V hardwire connection is required to unlock the full 9,000 BTU/2,800-watt heating output.

  • When hardwired for 240V, the Trivista Primis 50-inch outputs 9,000 BTUs and 2,800 watts, which is powerful enough to heat rooms up to 800 square feet. It features two heat settings — high and low — and also allows you to set a target temperature anywhere from 64°F to 82°F for precise comfort control.

  • Yes — the unit ships with included end panels that allow you to configure it as a 3-sided, 2-sided (corner), or 1-sided traditional built-in installation. This flexibility makes it suitable for a wide range of room layouts, from open-concept spaces to standard recessed wall applications, without purchasing additional components.

  • The unit itself measures 21.5 inches tall, 50 inches wide, and 9.5 inches deep. It is designed to be fully recessed into the wall, so framing must be planned carefully according to the minimum framing dimensions specified in Napoleon's installation manual — professional framing and electrical work is recommended before installation.

  • Napoleon covers electric appliances with a 2-Year Premium Warranty. Importantly, the manufacturer's warranty is only honored if the product is purchased from an authorized retailer — purchases made through unauthorized third-party sellers (such as some Amazon listings) may result in a denied warranty claim. Always verify authorized dealer status before purchasing.
