CAUTION
Sharp edges. Use protective gloves when
installing the plate.
For safety reasons, the heat shield must be properly
installed. This prevents components from overheating
as a result of the recirculation of hot air from the
cooktop.
The heat shield is the same width as the cooktop. For
shipping, it is screwed to the burner box.
After unpacking the cooktop, unscrew the heat shield.
The heat shield will be able to rotate freely, as shown
in the illustration.
