Well the moment of truth arrived today.  The heater guy came to set up the heater.  It appears that my free heater which was working when my friends took it down was not in safe storage.  Bottom line someone removed parts for the copper and aluminum.  It isn't worth repairing.  I was looking for a new heater and am most likely going to go with this.

They have a 120 BTU heater which should work for my greenhouse.
Anyone have any experience?  I have friends in NJ that sell them and say they are good and what they are using in there greenhouses.  Just curious.

Nothing in the link Sharon.

Maybe I chopped off something important

Well I own a heater and it is in the back of my van but the weather has prevented the installation.
