A:Answer Hi, thank you for your inquiry. Due to the innovations made to the Affinity models, the current model number you own (AGQ6700FS) and newly manufactured Affinity models are not compatible for stacking. Both appliances require different stacking kits because the specifications have changed. Due to safety concerns we do not recommend that they are stacked. We hope this information proves to be of assistance, we are also welcome to receiving any concerns or question you may have.
Best Regards-
