fire place and DVD cabinet

I noticed the cabinet containing our DVD player above the fire place in our 3600RL becomes very hot when the fire place is on for any length of time. Is this a danger to the DVD player, cables, and chords? Should the glass in the cabinet door be replace with some other type of vented material?

Tom, please do a search - this has been discussed before.

You need to raise the fireplace off of the carpet otherwise no air will circulate under the fireplace and it will overheat. I believe I used 3/8" plywood under the feet. Hope that helps.
