Crafted for compatibility with traditional‑style fireplaces, it includes decorative outlet grilles, frames, 90° elbows, and mounting hardware, allowing warm air to rise and circulate efficiently through up to 10 feet of ducting for enhanced comfort and energy savings. This kit provides a simple, reliable way to extend the usable heat from your fireplace while maintaining a classic aesthetic.
