Detector Replacement Requirements (Continued)
COOKING APPLIANCES
If the cooking appliance is located under an exhaust duct where
a detector has been mounted, it is normally not necessary to
utilize another detector for that cooking appliance, provided the
detector is not more than 12 in. (30 cm) into the duct. See
