This session will give you a run-down of how an LP system works with various appliances in your rig. LP gas is compressed by approximately 270 times by volume to create a liquefied form for convenient storage in containers. Therefore, the DOT cylinders and ASME tanks are made of heavy steel to withstand the pressure.
When the container valve is open and an appliance calls for fuel, the liquefied gas turns to vapor and passes through a regulator that adjusts the pressure to the specifications for the hoses, valves, and appliances. Once the valve is open, the LP vapor is available at the line to the appliance.
