Classic Flame - SKU# 33EB304GRS - Classic Flame 33" Builders Box Fireplace Mantel with Electric Insert Set

The 33 inch Built-In or "Builders Box" electric fireplace insert is designed to be professionally installed in a permanant structure like an actual fireplace or wall cut out. The Built-In electric fireplace insert produces energy efficient heat, is environmentally friendly, and may be used with or without heat for year-round enjoyment. The 33 inch Built-In electric fireplace insert shares similar features to the 33 inch Mantel Insert, but there are some major differences between the two electric fireplace inserts. Unlike the Mantel insert, the Built-In ...- Should be hardwired into a home's electrical system.- Should be installed by a contractor or electrician.- Includes a flip down front panel for easy access to service the unit through the front only.- Requires separate purchase of thermostat.- Offers two heat output functions: 4,600 BTUs (heats 400 square feet) or 9,200 BTUs (800+ square feet).- Has a 3-prong plug to be hard-wired in 120v or 240v outlet.The Built-In electric fireplace insert is more expensive than the Mantel Insert, but don't make the mistake of cutting corners. If you plan to seal the Mantel Insert in a permanant structure, you will not be able to gain access to the back of the Mantel Insert when its time to service the unit. The Mantel Insert can only be serviced through the back. The Built-In is serviced through the front via a flip down front panel. In addition to a 33 inch Built-In, we offer this same unit in two larger sizes: 39 inch and 45-inch.  more
