It would appear that after blowing the crud out of an LP line (I wasn't smart enough to trap it into a rag to see what is was) things are working AND I am pleased to report that they are working even better than I had thought.

  I ran the heater last night for about an hour and got the interior temp up to almost 70 with an outside temp below 40.

Sooo, indeed the heater is toasty and I'm gonna like it!
