Think of our outdoor firebox as the canvas that lets you create your ideal fireplace. Built using the same rugged construction as our fireplaces, the outdoor firebox is a ventless design that’s certified for use with an outdoor burner. The optional stainless steel drain pan is available to help control and re-direct any moisture that collects beneath the fireplace. Protect your fireplace with the available weather doors. To be used with Empire Harmony gas logs and Empire Loft burner kits.
