Hi All. I wish I had found this site a few weeks ago, but I have picked up some good info just browsing around. I bought a new 7100 a few weeks ago. I couldn't get much help with the installation, but my wife and I managed to get the unit up into the house and in place. (good to be married to an engineer). Everything seems to have fit together pretty well, but I am balking at the wiring. I'm definitely NOT an electrical guy, and the wiring instructions (page 38, Fig. 6.4) aren't crystal clear. Specifically I'm unclear on the ground wires. I have the 14-2 and 14-3 wires as called for. When I match the colors on the fireplace end, there is still a ground wire dangling out here. I reached around inside the unit but don't feel any stray wires in there. Electricity is all voodoo to me, but it is going to take time for either of the electricians I called to make the 30 mile drive out from town. Any help would be appreciated, and from the posts here it sounds like this is pretty basic stuff to most of you. Thanks.
