LP TANK FILLING PRACTICES
Any LP gas tank associated with the motorhome should never be filled to more than 80 percent of total
capacity. Filling should always be done only when the motorhome is leveled. If the motorhome is not
level, the tank may be overfilled (i.e., more than 80 percent of capacity) and, thus, subject the motorhome
to possible fire or explosion from resultant uncontrolled gas flows.
LP GAS REGULATOR
As noted earlier, the LP gas regulator (Figure 4-2) is the
“heart” of the LP gas distribution system. This regulator
reduces and controls the pressure of the gas on the outlet
end to provide a constant supply of gas at a constant
pressure to the gas-operated appliances. The regulator has a
vent to relieve excess pressure on the inlet side of the
regulator, should excess pressure develop in the gas tank
and connecting gas line to that regulator inlet. The vent
would normally release the excess LP gas to the atmosphere
until the over-pressurization condition is eliminated.
