Help! I'm installing this under cabinet range hood now. It measures 12" across the flat top of the hood, but the cabinet is 15" deep, so there'll either be a 3" gap behind the hood or in front of it.Gap behind will collect grease like no tomorrow. Gap in front isn't aesthetic. Any filler to fill behind would have to be flame resistant, I imagine? a stainless steel filler to match the hood would be ideal. Hood model is Cosmo U30.Is this normal? Any ideas?Thanks in advance.https://i.redd.it/ezqet2bbnax21.jpghttps://i.redd.it/7ns3qf7dnax21.jpg via /r/DIY http://bit.ly/2PWIRXN
