Dimplex Vital Spark 36" Built-in Electric Firebox FAQ
Can the Dimplex Vital Spark 36" be hardwired, or does it only plug in?
The Vital Spark 36" offers flexible installation. It is designed for 1500 watts at 120 volts and can be hardwired directly into your home's electrical system or converted to a standard plug-in using a plug kit. This makes it suitable for both new construction installations and retrofit projects where an outlet is already in place.
What size room can the Vital Spark 36" heat?
The Vital Spark 36" produces 5,118 BTUs from a 1500-watt fan-forced heater and is designed to supplement heating in spaces up to 1,000 square feet. It is intended as a supplemental heat source rather than a primary furnace, making it ideal for living rooms, bedrooms, dens, and finished basements.
Can I run the flames without turning on the heat?
Yes. The flame effect operates independently of the heater, so you can enjoy the lifelike flames year-round—even in warm weather—without producing any heat. This allows the firebox to function as a decorative centerpiece in any season.
How do I control the Vital Spark 36" firebox?
You have three control options: the included multi-function remote, the discreet built-in control panel on the unit, and the free Glen Dimplex Connect app for smartphones and tablets. The app allows you to adjust flame color, speed, brightness, and heat settings from anywhere with a Wi-Fi connection.
Does this electric firebox require venting or a chimney?
No. The Vital Spark 36" is a 100% vent-free electric firebox. It does not produce smoke, fumes, or emissions, so no chimney, flue, or gas line is required. This makes it safe and easy to install in nearly any room of the home, including apartments, condos, and basements.
What are the framing dimensions I need for installation?
The required framing/rough opening is 34 3/4" wide x 26 1/4" high x 9" deep. The firebox itself measures 37 1/4" W x 26 1/2" H x 9" D, with the trim flange overlapping the opening for a clean finished look. Always consult the installation manual for full clearance and combustible material requirements before framing.
Is the Vital Spark 36" approved for use in mantels, cabinets, or existing masonry fireplaces?
Yes. The Vital Spark 36" is approved for installation in existing wood-burning fireplaces (after proper preparation), custom cabinets and mantels, and new in-wall framed openings. Its slim 9-inch depth and fully recessed design make it especially versatile for retrofit projects.
What warranty comes with the Dimplex Vital Spark 36"?
The Vital Spark 36" is backed by a 2-year limited manufacturer warranty from Dimplex, covering defects in materials and workmanship under normal residential use. As an authorized Dimplex dealer, ElectricFireplacesPlus.com ensures every unit includes the full factory warranty, with support available by phone at (800) 974-4876 or by email.
