This wind directional chimney flue cap helps prevent problematic downdrafts in the fireplace. This proven solution is ready to connect to Ventis Class-A chimney pipe. When installed, the pivoting hood is kept in proper position, relative to the wind, by the vane. Air movement past the hood creates a partial vacuum in the flue, enhancing efficiency and helping to prevent downdraft. The screen helps redirect wind for extra downdraft protection.
