270 | Section 7 LP-Gas System ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ----------------- Monarch SE 2004
LP-Gas is compressed into liquid form in the tank. Only the vapor is used during
combustion by an appliance. As vapor is removed from the tank, the remaining
liquid will vaporize to maintain pressure that is removed during consumption.
This process will continue until there is no liquid remaining in the tank.
Temperature affects action of the liquid to vaporize. If temperature of the liquid
is - 44º F. the liquid remains stable with tank pressure, about 0 psi. If liquid
temperature is 100º F. the liquid quickly vaporizes with tank pressure, about
200 psi. Vapor pressure must remain relatively consistent regardless of temperature
so that appliance heat output remains stable. Vapor pressure regulation is performed
by the regulator.
