A:AnswerThe convection fan unit on the Breville Smart Oven Pro is on the right side of the toaster oven and appears to be well made/vented/protected so I'm thinking it should be problem free. I just took a look at my GE Profile dual fuel convection oven and that fan housing unit seems similarly well made/vented and I've had this oven 14 years! The Breville Smart Oven Pro is awesome! You will love it and not regret the purchase one bit! :)
A:AnswerLike most appliances sold in retail stores, it's rated for household use, by consumers. You should contact the manufacturer to see if there is a commercial variant.
A:AnswerThe geek squad warranty runs concurrently. The only advantage is that you don't have to ship the item to Breville if something goes wrong. Bestbuy will handle all that. And they might give you a replacement.
A:AnswerThe Smart Oven Pro includes a baking pan, broil pan, pizza pan. crumb tray, wire rack and sold separately is a bamboo cutting board accessory, pizza stone accessory, etc.
A:AnswerThe feet of the unit are inset from the sides of the toaster oven and they measure 17.5 inches. I would allow a bit of clearance due to manufacturing differences and the taper of the legs.
The width of the toaster oven measures 18.5 inches. I would think your 20 inch appliance slider would work just fine.
