Vacu-Stack Stainless Steel Chimney Cap
for Air Cooled Double & Triple Walled Metal Chimneys 10"
The Vacu-Stack Chimney Cap prevents "wind induced downdraft" regardless of wind direction
(even downward). Accelerated air flow around the Vacu-Stack creates a venturi causing flue
gases to flow up and out of the chimney. These models are specifically designed for installation
on double and triple walled air-cooled chimneys. These models feature seperate passages for cooling
air to flow uninterupted through convection cooled chimneys.
