Gas fireplace overheating? Help!?

Recently had Valor gas fireplace installed. Noticed the brand new flat screen lcd tv screen had strange pattern developed, a swirl pattern you can see when tv switched off. Felt behind tv (mounted almost 2 feet above f/p, to code), and it was very very hot. Felt top of satellite receiver which is recessed and about 5 feet above fireplace, it was even hotter. Took temp readings today - after 3 minutes, both areas read 118 degrees (and climbing). The built in surround itself was hot to the touch. I believe it was built with drywall or cement board, not sure which. There is a power outlet that was installed when the f/p was installed (for tv/satellite) and I worry about fire hazard or melting wires with all the wiring inside the surround. Any suggestions on what the fix may be - and whether the high temps. are in fact a hazard in any way? Advice appreciated! p.s. fireplace company saying this is not a problem and suggested WE pay more and buy a blower to solve it - don't want a blower as that would make it so we can't use f/p if power fails. Will it ruin our electronics or more importantly, be a fire hazard if we continue using the f/p when such hight temps are present?
