Odors and smoke are normal when the oven is used the first few times or when it is heavily soiled.
IMPORTANT: The health of some birds is extremely sensitive to the fumes given off by the oven. Exposure to the fumes may result in death to certain birds. Always move birds to another closed and well-ventilated room.
Aluminum Foil on oven bottom
IMPORTANT: To avoid permanent damage to the oven bottom finish, do not line the oven bottom with any type of foil or liner.
Covering the oven bottom can trap spills and debris resulting in odors.
For best cooking results, do not cover entire oven rack with foil because air must be able to move freely and the foil can trap debris causing odors.
