IMPORTANT SAFETY INSTRUCTIONS

When baking frozen pizzas or pies, place them on the wire rack
lined with parchment paper. Do not use the baking tray or the
roasting pan for frozen foods with a large surface area. The tray or
pan could become warped and difficult to remove from the oven
when hot. Frozen foods like french fries, chicken nuggets, etc. can
be baked on the baking tray.
