I have the older Espar B4 model and have used it for over four years in my Transit with no problems. It uses the Ford factory straw and doesn't have an altitude kit (my installer says he checked with Espar and the gasoline models don't need them). I've used the heater at altitude (up to 8400 feet). Also for skiing in the winter.
I've never had a problem starting the heater except when I have let the gas tank run too low. I'm not sure this helps you, but it might add a bit of grist to your diagnostic mill.
Cheers.
