I let my propane tank run out.. They just refilled it for me, but I can't figure out how to get the pilot light lit. can you help?

Procedures may vary from manufacturer to manufacturer, but you have to put it to a light postiion and hold it how as its lit until the termocouple gets hot enough to release... then you adjust it to the correct temprature.

If as you say happened you ran out of propane the possibility of air in the lines might mean this takes a lot longer than usual to relight.
