HAHAHA . . . This thread reminds me of the blind men trying to describe the elephant by touching it. Everyone has a different take . . . An exploded parts diagram will settle this discussion in seconds. Go on the web and find it....

It was nine blind men discribing different parts of an elephant.

Hahaha, that's hilarious! Sorry, I had mentioned the two furnaces in the original post but I should have emphasized it a bit more, my fault. Thanks for everyone's help I'll repost with better pics when I get the chance and I'll label them correctly just for kicks

Hey guys, finally got some photos of the two furnaces in full The only thing I really think I need to comment on is that a solid pipe is actually going into each of the sides of the furnaces, and I believe that is the actual gas line. Was in a rush so just took the photos and left.

The solid pipe is gas. Copper is NOT used on gas, so it is water feed or drain line or coolant.

Hope that helps.

Careful: copper is used for gas in meny places!!

Second from bottom picture is gas and electrical. The green hose looking line is probably the drain for the AC.
The picture above with the red shut off is the gas line.

The clear hose in the top picture is the AC drain. You can see the red gas shut off again in that picture on the left.
The big green lump in the next picture is the humidifier. The line going to that will be a water line.
