The zero-clearance Flex Island fireplace insert is designed as a room divider, with four open sides enabling the hypnotic flame to be viewed from the front, back, left and right sides. The UL Listed Flex Island models come with a base component that holds the burner and a top component that lines the bulkhead above. The clean lines and 'all flame' configuration of the Flex 18IL means the entire viewing area is dedicated to the eye-catching flame, creating a harmonious blend of traditional style and contemporary design. The included AB3 Burner holds 0.7 gallons of clean burning e-NRG bioethanol and will deliver a magical dancing flame for up to 11 hours. It is designed to deliver robust performance with the power to heat approximately 215ft2, making it ideal for smaller residential spaces.
