IMPORTANT SAFETY INSTRUCTIONS

Do not install kitchen cabinets above the range, since reaching
over a hot stovetop to access the cabinets can result in burns. If it is
necessary to install cabinets, you can reduce the risk of burns by
installing a range hood that extends at least 4 3/4" (12 cm) past the
bottom of the cabinets.
