SS Vacu-Stack

The Vacu-Stack Is The Best Solution For Wind Induced Downdraft.
Stops wind from blowing into the chimney.
Prevents “wind induced downdraft” regardless of wind direction (even downward.) Accelerated air flow around the Vacu-Stack creates a venturi, causing flue gasses to flow up and out of the chimney.

Features:

  • 100% Stainless Steel Construction
  • Easy To Install, Self-adjusting Spring Fit
  • Wind Tunnel Tested
  • Tested To UL 103 Standard
  • Lifetime Limited Warranty

Note: For Class A, Single Wall and Masonry Chimneys.
A Masonry Adapter, purchased separately, is required when installing a Vacu-Stack in a masonry chimney. (Item# 1244 & 1216 Include Masonry Adapters.) Masonry Adapters Include Fasteners.
