Please help. They delivered my new gas range today and will be hooking it up. I’ve been informed to do a burn off before allowing my Parrotlet Kai out of the sealed off room he has been living in for several weeks now. What exactly is burn off time and please tell me for how long? Someone mentioned it was the oven and they ran it on 400 for two hours while another person said it was the time it took the gas to run through all the burners. Are they both right? I’m very confused and need to get this right the first time. Any advice would be greatly appreciated. Worried.
