Product Overview
Chaska 335S Gas Fireplace Insert
The Kozy Heat Chaska 335S gas fireplace insert turns an existing masonry fireplace into a clean, efficient heat source. The 335S uses a millivolt valve system that operates without electricity, providing power-outage reliability that pure-electronic systems can't match.
The 335S delivers 36,500 BTU/hr input with an 80% efficiency rating - one of the most efficient inserts in Kozy Heat's lineup. Customize with nine screen front options, three media options (traditional log, rock and glass, or rock media), and a range of refractory linings.
The Chaska 335S is part of the Kozy Heat collection at Custom Fireside.
