Monessen Exacta 36" Ventless Firebox

The Monessen Exacta 36" Ventless Firebox combines advanced technology with a timeless design, providing efficient warmth and ambiance to your space. Paired with a Monessen vent-free log set, this firebox creates a cozy, inviting atmosphere with a sleek, clean look.

Designed with a louverless, minimal frame, the Exacta enhances your view of the flames, while hideaway screen pockets keep screens discreetly hidden when not in use, offering an uninterrupted view. The firebox’s angled construction and specially engineered air channels ensure efficient heating by circulating more warmth throughout the room, all without the need for venting, which keeps fuel costs low.
