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°, on the cold cylinder, or by manifolding two
propane bottles together to increase total vaporization
capacity. It is recommended that a minimum 100 lb.
propane bottle be used on the machine, depending on
the length of running time desired.
Burner Features
Operated Automatic Valve
This machine is equipped with a thermopile self-
powered combination gas control. This system is
designed as a constant burning pilot. Lighting of the
pilot is accomplished by manually lighting the pilot. A
thermostat and flow switch control the main solenoid
valve.
Care of Main Burner
Due to condensation from heater coils dripping down
on the burners, scale build-up may occur in the burner
jet orifices.
1. To Remove Burner Manifold From
Water Heater Coil:
Turn off the gas at the main burner by turning
the knob to the “OFF” position on the gas valve
and main gas supply.
Disconnect the pilot and ignition lines from the
gas valve. Disconnect union in main burner line.
Slide burner manifold out through shell opening.
2. To Clean Burner Jets:
Select proper size drill for type of gas involved.
Use pine vise to hold drill and then ream out
each jet orifice.
CAUTION: Do not ream out orifices to a larger size.
