This is what I'm experiencing. My guess is that my gas velocity is just too low when the burner is cranked way down. Anyone know of a fix other than opening up the valve a little more?
They do indeed. I have noticed one bad thing using them though. When I have the needle valve turned down very low while mashing and the PID turns on the solenoid valve, the gas flow is isn't great enough and combustion will actually back up into the burner venturi tube and I'll have no flame...
