EcoSmart Fire Flex 158SS - Single Sided Bioethanol Fireplace Insert / Media Wall


Architectural flames, limitless design freedom

 

The EcoSmart Fire Flex 158SS brings dramatic scale to your space with an expansive 4,030mm-wide viewing area and a single-sided design that showcases the flame from the front.

Designed for single-room applications, this zero-clearance bioethanol fireplace creates a striking focal point in feature walls, integrated cabinetry and fireplace settings. Choose the uninterrupted all-flame configuration, or opt for BX2 with two decorative boxes for a different architectural expression. Available with stainless steel or black burner finishes.

 

Key Features

 

True zero-clearance installation

Self-contained, zero-clearance construction provides exceptional installation freedom and flexibility for builders, architects, interior designers, landscapers and homeowners.

Indoor or outdoor application

Powered by clean-burning e-NRG bioethanol fuel, the Flex 158SS is suitable for indoor or outdoor installation. Bioethanol is a sustainable fuel choice made by fermenting plants such as sugarcane or corn.

Industry-exclusive decorative box

Optional or included box configurations are available for select firebox lengths. Fill the decorative box with a non-combustible accessory, or choose the optional eye-catching log set in a copper finish.

Warmth and atmosphere

The Flex 158SS combines a real bioethanol flame with warmth and a striking architectural presence, without a chimney. Heating performance varies by configuration and installation conditions; see the burner comparison below.

Installation flexibility

No chimney or flue is required. Installation must follow the manufacturer’s instructions, including ventilation and minimum room-volume requirements.

Additional Included accessories

Each Flex includes decorative Black Glass Charcoal and an integrated fire screen that sits flush behind the frame.
