WATER FLOW: Connect a pressurized water source to the INLET GAR-
DEN HOSE CONNECTION (1) and turn on the water supply.
The water then travels into the TRIPLEX HIGH PRESSURE PUMP (2)
which has an UNLOADER (6) that bypasses the water when the trigger
gun is closed. To protect the pump from heated water during this bypass
stage, a HEAT DUMP VALVE (5) will open at 140°F/60°C allowing the
heated water to escape. The Heat Dump Valve automatically resets when
the water cools. The PRESSURE SWITCH (7) controls the fuel supply to
the burner.
From there, the water will flow into the HEAT EXCHANGER INLET (10)
where it is heated when the burner is on. As the water exits the HEAT
EXCHANGER OUTLET (11), it enters a safety system which protects the
operator from danger. The safety system contains a HIGH TEMPERA-
TURE LIMIT SWITCH (12) which senses the water temperature and
shuts off the fuel supply to the burner if it gets too hot. If the unloader
fails to bypass the water or the burner remains on when the trigger gun
is closed, the SAFETY RELIEF (13) will relieve and allow water to exit
safely.
The heated water then flows through the HIGH PRESSURE HOSE (14)
and to the TRIGGER GUN ASSEMBLY (15) which allows the operator
to control the water spray. When the trigger gun is open, the water flows
through the LANCE (16) and exits the NOZZLE (17).
FUEL FLOW: The Fuel Pump draws fuel from the FUEL TANK (18)
through a replaceable FUEL FILTER (4) and into the FUEL PUMP (3).
Fuel exits the fuel pump, into a FUEL SOLENOID VALVE (8) which con-
trols fuel flow to the FUEL NOZZLE (9) where it ignites and burns in the
heat exchanger.
EMF SYSTEM: The patented Electro Magnetic Firing (EMF) System is an
integrated system which gives all the requirements for
combustion.
The BELT (1) from the power source turns the HUB (2) which has two
EXTERIOR MAGNETS (3) attached. As these magnets spin past the IG-
NITION MODULE (4), a magnetic flux is created from which the ignition
module produces a high voltage. This voltage arcs across the electrodes
giving the spark that is needed for ignition.
This hub has an INTERNALLY MOUNTED MAGNET (5) which spins past
a STATOR (6) that produces the voltage that controls the fuel supply to
the heat exchanger. In addition to this, the hub also spins the BLOWER
FAN (7) that forces the air into and through the heat exchanger.
The FUEL PUMP (8) is also connected to the hub by means of a flexible
coupler.
