564 Diamond-Fyre™

This 564 Diamond-Fyre GSR2 is a mid-sized gas fireplace that features a single ribbon burner and under lighting to illuminate a contemporary fire presentation. With a depth of only 16 1/4 inches, combined with a BTU output of 20,500, this fireplace is big on beauty and small on space. With a large turn-down ratio of up to 47%, and a low input of 11,310 BTUs with natural gas or 10,780 BTUs with propane, this allows for great flexibility for year-round use.

The 564 Diamond-Fyre GSR2 is an ideal solution for those looking for a more contemporary fire that replaces the traditional logs and embers with a sleek crushed glass floor and modern dancing flames. This fireplace now comes with the new GreenSmart wall mounted remote that allows you to operate the pilot (continuous to GreenSmart), accent light, flame adjustment and the standard 180 CFM blower.
