Purging Propane Lines

The camper in question has sat unused for possibly 10 years with no tanks attached, just the quick connect lines to the bottles dangling.

The first issue was the regulator. I guess it got fried just baking uncovered for all those years. That has been replaced.

Now I'm having great difficulty getting the stove top burners to light. One will kind of light with a very weak flame. The furnace will not light, and I haven't tried the water heater or refrigerator.

The order of the appliances from the tank back is: refig, heater, stove, water heater.

I've had all the burners wide open trying to get some propane to flow, but all get is the very weak flame that kind of sputters.

I realize there is likely air in the lines and that the heavier than air propane is only coming out of the regulator at 10-12 inches of water, but what am I doing wrong? What should I do differently?

    You have a leak somewhere.

    Rubber hoses don't last long when outside. I covered them with split-loom cable cover, this should help against UV but don't expect it to last forever.

    Black iron pipes and Tees corrode too, check them from time to time.
