2 of us put together in 90 minutes.  The directions are not that great.  Call all sides "D" when 2 of the sides are different, and the same with the poles that are "F".  Pay attention to the schematic and don't fully tighten the screws until end.  With that said the bottom of the door doesn't close completely.  So far our ignition switch does work.  We put a tank from our grill in last evening and it worked!  Looking forward to more evenings with this little fireplace!!
