- Drawing a kitchen hood without labeling every cooking appliance and its fuel source (gas or electric).
- Omitting the hood CFM exhaust rate or the exhaust fan manufacturer's specifications from the scaled hood drawing.
- Omitting make up air type, location and CFM supply rate for a kitchen hood.
- Ending a condensate drain at a receptor that is not on the approved list, such as one other than a floor sink and drain, hub drain, trench drain, mop sink standpipe, utility sink, lavatory wye branch tail piece or bathtub overflow pipe.
- Leaving out walk-in cooler/freezer details such as the quantity of refrigerant or the condensate drain termination point.
- Not labeling the type, location and size of roof accesses when equipment is installed on the roof.
