REFERENCE GUIDE
This is a backup safety feature, if the system pressure exceeds the set
pressure this device will stop the burner from firing.
Mechanical device that senses water flow
Steel piping wound together with an inlet for incoming cold water
and outlet for hot water to exit.
Means of connecting garden hose to pump inlet. Connect garden hose
here.
A device that moves fluid through a combination of suction and
displacement.
Fuel storage container for diesel fuels.
Vented cover for fuel tank.
Valve that regulates pressure and directs flow into bypass when
trigger is closed.
The air-cooled engine powers the pump.
Connection point for the high-pressure hose.
Filter in fuel line that removes water and screens out dirt and debris
from fuel.
Device that heats the water by forcing a flame across steel pipe.
Gas tank is a container for holding gas and gas cap is cover for gas
tank.
Used to divert water out to nozzle.
Section of wand to extend length and provide stability.
Rod to extend length.
Housing device for mounting switches and machine controls.
Device for protecting circuit from damage if overloaded or shorted.
Acts as an on/off device for power to burner components.
Control Device that limits the water temperature.
A space for storing nozzles.
Safety device that discharges hot water from the pump manifold
during long bypass operation.
System provides air, fuel, and ignition for combustion
Siphons cleaning chemicals into a law pressure washer spray
downstream of the pump.
Safety device that will open and relieve excess system pressure
Device for sensing if the burner has a flame
