I've worked with propane systems quite a bit and I've read multiple threads on different forums about the "open the valve slowly" theory and on just about every post pertaining to propane problems, that's the first thing that gets jumped on and it's always supported with several "my brother-in-law had the same problem" posts. I'm still trying to wrap around the idea that a properly functioning propane system that delivers enough propane in volume and pressure to sustain operation of a fridge and water heater, but will not allow a furnace to ignite, and I just can't get there. All propane devices operate at a regulated pressure of 11"WC. Would someone please explain how this can happen?
