This is going to be similar to Grizburner's recent post, but with a different setup. Just had the P.E. Alderlea T5 installed. Fired it up, slowly at first due to some wetter wood (I know, I know-no lectures please)....anyway, finally got it firing pretty good and noticed some new stove smell in the lower level, no big deal. But then in the bedroom above, the insulated Excel piping started smelling like cat urine or maybe seafood of some sort. More disturbing was that it was very hot to the touch (no I don't have a thermometer yet). It was so hot that if you left your hand on it for more than a second you would be burned. Also, the seam on each section of stainless steel pipe was blackened. It was almost like the insulation in the pipe was burning?? WTF! What a buzzkill. I've already heard from some of you that a super hot insulated pipe means that likely something is wrong. I can't get a hold of the installer who put it in but will try tomorrow. I figured you guys probably know more anyway so.....any ideas?
