Thanks for stopping just short of some really descriptive names!
I understand the risk we took. (Now) and thanks for your help, despite the fact that you may have opened yourself to a lawsuit from my dead family!

Just a clarification since you think I'm such and idiot, was this unit was used in a new mobile home and was virtually brand new. it is the same size and make as my previous model, installation was a simple as removing some foil tape undoing
4 sheet metal screws and a wall bracket, undo the 2 power lines and the few thermostat wires, turning and sliding up the chimney, undoing the gas line flex hose sliding out the old unit.
sliding in the new then reversing everything that I did. not actually in that order. took less than 1/2 hour.

The longer I type, the less angry I become, because you are very right, and I got lucky. I didn't appreciate the way you made me feel, but it was important for others to read this and learn from my mistakes before someone does get hurt.
Don't assume the info you were given was right, and the few hundred dollars I saved may have cost me a whole lot more than money, right? who would have guessed that a new furnace that had been in use wouldn't have had an orifice in it? but, that is why I should have checked. there are many constructive ways to say the same things, I just took offense to having my ignorance pointed out to me.

Thanks for the help and the good advice. and we'll get a qualified tech in here if they'll come or start from scratch.
and thanks for the harsh words, they taught me a valuable lesson that i'm glad I didn't learn the hard way.
