Have all of the beauty and ambiance of a traditional masonry fireplace without the hassle and pollutants of woodburning.

Available in 39”,44”,49”, and 43” See-through, our gas burning fireplace is the right choice for builders and homeowners looking for a hassle free gas only fireplace. The Burntech GBVS Series comes complete with our lightweight modular fireplace kit, a remote control operated realistic gas log set, and our patented B-vent components.


The lightweight modular masonry construction makes installation fast and easy. The GBVS uses a 10” B-vent flue system allowing installation with smaller framing dimensions than those required in wood burning fireplaces.  Flexibility in design allows the customer freedom of choice to install on either a concrete foundation or on wood framing.

Finish off your Burntech Fireplace system with firebrick of your choosing or use a Burntech Firebrick Liner kit (sold separately) available in herringbone and standard runningbond.


As with all Burntech fireplaces, the Burntech Gas B-Vent Fireplaces are covered by our Lifetime Limited Warranty on all modular masonry components*.
