The SL-350TRS offers the most compact dimensions available. This full featured fireplace creates unlimited installation opportunities without sacrificing the view of a beautiful Heat & Glo fire. The SL-350TRS features Heat & Glo's TR Technology that allows it to be vented off the top or rear while still maintaining a sealed combustion firebox. Additionally, the SL-350TRS is AFUE rated, meaning it has been tested and approved to the same standard used for today's energy efficient heaters. You can even regulate the temperature in your room using your fireplace and an optional wall or hand-held remote control thermostat.
