Query: Endless Summer Patio Heater - Don't Buy it

A couple of calls to customer service, many skinned knuckles and at least 8 hours of labor - and I still can't get this patio heater together (hence the name "endless summer?"). The hang up is "step 9" - attaching the gas line and regulator assembly. They simply don't attach. I've called the company and spoken to two people. They know this is a problem and kindly expressed their confidence in my ability to "get it done." I'm not a total incompetent and I'm a pretty strong guy. I've gone at this assembly in five different ways, lubed the fittings, etc. In my defense, my race car mechanic neighbor and a mechanical engineer friend also failed to mate these fittings. The replacement part I was sent also doesn't fit. At this point, I've got far more labor and frustration in this patio heater than it is worth - and, insult to injury, I'll likely have to pay to drop it off at the landfill.
