Jenn-Air's ventilation system is designed to capture both cooking fumes, smoke and
steam. If the system does not, these are some ducting installation situations to check:
• 6" diameter round or 3 V4"x 10" rectangular ducting should be used. Note: 5"
diameter round ducting may be used if the duct length is 10' or less.
• No more than three 90° elbows should be used. Distance between elbows should
be at least 18".
• Recommended Jenn-Air wall cap should be used. Make sure damper moves freely
when ventilation system is operating.
• There should be a minimum clearance of 6" for cooktop installed near a side wall.
if there is not an obvious improper installation, there may be a concealed problem such
as a pinched joint, obstruction in the pipe, etc. Installation is the responsibility of the
installer and questions should be addressed first by the installer. The installer should
very carefully check the ducting installation instructions.
