Help!!! Hot!

[steen]

I just got my corn's tank completely set up (it's getting here Friday!!!) and I plugged in the UTH. It's a ZooMed ReptiTherm U.T.H, made for 10-20 gal aquariums...and it's getting really hot! I'm not sure what it's supposed to feel like, but this seems awfully warm to me. It's been plugged in for an hour, and it's hot enough that I can't leave my hand on the glass very long. Do I need to worry about my baby burrowing in the substrate (aspen shavings) and burning itself?? Would it be ok to put a dishtowel or cage carpet between the substrate and the glass?? I don't want anything bad to happen to it... Please help!!!
