LP issue? Maybe?
I noticed that if I am not using the gas as in the water heater or refer, but keep the tanks open, and go to switch the refer to gas, that it errors and I have to turn on a burner for a bit to get gas...

When NOT using any propane for extended periods and Propane is valved for service then LP Reg goes into 'Lock-up' condition (normal)
What this means is W/O propane demand the reg can NOT hold 11" WC and pressure will rise...reg then goes into 'lockup' to prevent over-pressurization of system
Then you have to place a 'demand' on system.....lowers system pressure/reg then controls pressure & flow.
Can take a few minutes to fill ALL lines in propane system as each appliance attempts to light off.
OPD only stops flow of liquid into cylinder during filling processat 80% liquid level
OPD will NOT stop flow of vapor out of cylinder thru service valve
*Excess Flow Limiting Check Valve inside the ACME Green Nut CAN trip if service valves are opened too fast
Ah, this makes perfect sense then.I just wonder what happens to the flammable gas that is already in the line, I can hear it escaping through the burner. Since I never shut the tanks off unless I am changing one, and still have plenty of gas, I know it isn't leaking anywhere, so guess the only puzzling part is what happens to the gas in the lines when the reg shuts down?
The WHOLE LP System downstream of reg is only at 11" WC (0.4 psi)
And there is NO FLOW
When you first place a demand (stove top burner, fridge/water heater/furnace etc)on system the line pressure drops faster then Reg can respond and begin controlling pressure.
Air/fuel ratio is out of whack UNTIL that controlled flow is established and reg is controlling system pressure
(air/fuel ratio for propane is very narrow range)
