Rupture Disk
If pressure from pump or thermal expansion should
exceed safe limits, the rupture disk will burst, allowing
high pressure to be discharged through hose to ground.
When disk ruptures, it needs to be replaced. The
Rupture Disk should be replaced every two years.

Propane Cylinder Capacity
An important consideration with propane systems is the
capacity of the supply cylinder relative to the needs of
the burner. The burner operates on propane as a gas;
as gas is used from the propane cylinder, the liquid in
the cylinder boils to maintain gas pressure. This boiling
process cools the liquid, and in a heavy, continuous-
demand situation, the liquid temperature can fall to the
point at which it cannot provide gas as rapidly as is
needed. In this case, it may be necessary to warm the
propane cylinder by directing a warm spray, not over
120° F, on the cold cylinder or by manifolding two
propane bottles together to increase total vaporization
capacity. It is recommended that a minimum 30 lb.
vapor propane bottle be used on the machine.
