Copper Cable (CAT5 and CAT3) and heat

One of my clients is worried about the cat 5 cable that I have running through his baseboard heating.  He is concerned that it will cause "slow downs" and can potentially cause a fire.  Do I have anything to worry about here.  I used PVC cable.

    Hmm.  Have you tested it with the heat turned on?  Does the cable get hot?  I wouldn't do it - especially with PVC cable - supposedly if it catches fire it gives off poison gas.  Is that the ONLY way to run the cable!?!?!

    I don't think it will cause "slow downs".

    The bigger problem with PVC clad cable is the potentially toxic fumes if it does burn. Getting any cables too close to a heat source is never a good thing. All the wires have is a plastic coating to keep them from shorting out. Heat melts platic pretty easy.. "Plenum" rated cable has a non-PVC jacket that is non-toxic if it burns.
