1. For ceiling mount installations, be certain that overhead structure is sufficient to support the hood’s weight.
2. Any obstruction of the hood’s exhaust air outlet must be avoided. An air diverter directs the exhausted air to
the rear and sides. Zero [0”] clearance from top of diverter to ceiling or overhead obstruction is allowed,
however DO NOT block or obstruct the area around d verter open ng. A blockage can significantly impact
hood capture, which may result in unsatisfactory performance.
G les recommends to allow some clearance for future moving, service or maintenance.
