I've read the sticky about setting up an AP, but I'm using a zilla UTH instead of Flex Watt.
I taped the UTH to the bottom of the enclosure (sandwiching the thermostat probe between it and the cage) with aluminum foil tape, instead of using the adhesive backing... however I left the protective cover on the adhesive - should I have removed this and (I'm not sure) cleaned the adhesive off or covered it with something different?
I was only concerned that whatever you would normally peel off to expose the adhesive is flammable or dangerous under heat in some way.
