It operates at up to 28,000 BTU\/h with a minimum output of 21,000 BTU\/h and delivers 99.9% efficiency, meaning virtually all combustion heat enters the living space rather than escaping through a flue. The unit includes an electronic ignition system with battery backup so it lights reliably even during power outages. A multi-function remote is included, covering IPI\/CPI ignition control, thermostat, flame height, blower, and integrated floor lighting. Licensed HVAC and hearth professionals typically handle installation to meet local mechanical and fuel gas codes.\u003c\/p\u003e\n\u003cp\u003eThis fireplace is suited for residential applications where venting is not feasible or desired. The F4686 fits into a framed rough opening of 29 inches H by 55 7\/8 inches W by 18 inches D. It ships with platinum crushed glass media and a standard black painted interior. Optional accessories include a porcelain liner, driftwood logs, river rocks, and decorative surrounds.
