What is the difference between the Built-In “Builders” Box and the Plug-In Firebox?
Both the Dimplex and Classic Flame Built-In Electric Fireboxes are designed to be installed and hard wired into a buildings electrical system (although plug kits are available). These units support either a 120-volt service or a 220/240 volt service. The 220V service produces higher heat output (9600 BTUs) than the 120V option (4600 BTU’s). This is different from our Plug-In electric inserts/fireboxes which are made to go directly into our corresponding mantels. They cannot be wired directly; instead they simply plug into any standard 120 volt household outlet.
