NOTE: To prevent potential heat damage to drywall, do
not mount the device directly onto drywall. Mount a piece
of 1/2 in (13 mm) thick plywood between the device and
the drywall.
NOTE: To ensure proper ventilation, the device must be
installed vertically on a vertical surface. Install device
with 6 in (153 mm) of clearance from the top and bottom
of the device.
