The sales lady at the local appliance dealer said it would be a bad idea to put a Wolf gas range into my island with a pop up downdraft. She said that because of the BTUs of the range there's an increased risk of fires being sucked down into tthe pop-up downdraft. Not sure I worded that right but it sounded scary. She said she'd feel much more comfortable selling me a Jennair freestanding range with down draft (pop up or integrated). Is this just her sales schpiel or does she raise a good point? Help!
