Electrical:
This machine, when installed, must be electrically
groundedin accordanceto localcodes.Check for proper
power supply using a volt meter.
Placement:
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and
walls.(Two feet away from walls should be adequate.)
Water Source:
Thewater sourcefor thepressure washershouldbe sup-
plied by a minimum 5/8" I.D.garden hose with a city wa-
ter pressure of not less than 30 PSI. If the water supply
is inadequate, or if the garden hose is kinked, the at-
tached pressure washer will run very rough and the
burner will not fire.
Connection:
See Component Identification on page 7.
Venting:
Adding exhaust vent pipe to your oil fired burner is not
recommended because restricted air flow causes car-
bon build-up, which affects the operation, and increases
maintenance on the coil.If a stack must be used, refrain
fromusing90degreebends.Ifthepipe cannotgostraight
up then use only 45 degree bends and go to the next
size pipe.The overall pipe length must not exceed 6 feet
in length.
STARTING AND OPERATING
INSTRUCTIONS
To Start:
1. STOP!Read operator’s manual from both the pres-
sure washer and the HP before operating.Failure to
read operation and warning instructions may result
in personal injury or property damage.

The areas around the HP should be kept clean and free
of combustible materials, gasoline and other flammable
vapors and liquids.
The flow of ventilating air to the burner must not be
blocked or obstructed in any manner.
MAINTENANCE AND SERVICE
Winterizing Procedure:
Damage due to freezing is not covered by warranty. Ad-
hereto thefollowing coldweather procedureswhenever
the washer must be stored or operated outdoors under
freezingconditions.
During winter months, when temperatures drop below
32°F, protecting your machine against freezing is nec-
essary.Store the machine in a heated room.If this is not
possible use compressed air on the short hose end. By
injecting compressed air, all water will be blown out of
the system. Run anti-freeze through the system.
Rupture Disk:
Forsafety,each machineisequipped witharupture disk.
In the event the pressure of the water should exceed
8000PSI, therupture diskwill releasepressure andwa-
ter on to the ground.
When the disk ruptures, it will need to be replaced.
NOTE:Turn burner switch off.Then open spray gun
to cool heating coil or rupture disk will burst over
time.
AdjustableThermostat:
The adjustable thermostat can be set between 100°F to
225°F (37.8°to 108°C) . The temperature is dependent
on water flow and ambient water temperature.
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate
rapidly inside the coil pipes.This growth is increased by
theextremeheat buildup inthe coil.The bestprevention
for liming conditions is to use high quality cleaning de-
tergents. In areas where alkaline water is an extreme
problem, periodic use of Deliming Powder will remove
lime and other deposits before coil becomes plugged.
Deliming CoilsWith A Pressure Washer:
Periodic flushing of coils or optional float tank is recom-
mended.
Step 1 Fill a 5 gallon bucket with 4 gallons of water,
thenadd1lb.ofdelimingpowder.Mix thoroughly.
Step 2 Removethehigh pressurenozzlefrom thepres-
sure wand and put the wand into the bucket.
Secure the trigger on the spray gun in the open
position.
Step 3 Attach ashort section(3-5 ft.)of gardenhose to
the attached pressure washer to siphon solu-
tionfrom theelevated bucket. Startup pressure
washer, allowing solutionto bepumped through
pressurewasher andintoHPcoils andback into
the bucket. Solution should be allowed to circu-
late 2-4 hours.
Step 4 After circulatingsolutionflush entiresystemwith
freshwater.
Removal of Soot In Heating Coil:
In the heating process fuel residue, in the form of soot
deposits, may develop between the heating coil pipes
andblockair flowwhich affects burnercombustion.When
soot has been detected on visual observation, the soot
on the coil must be cleaned off.
Fuel:
Use clean fuel oil that is not contaminated with water
and debris.Replace fuel filter and drain tank every 100
hoursof operation.UseKerosene No.1orNo.2 Heating
Fuel (ASTM D306) or diesel only. NEVER use gasoline
in your burner tank.Gasoline is more combustible than
fuel oil and could result in a serious explosion.NEVER
use crankcase or waste oil in your burner. Fuel machine
malfunction could result from contamination.
Ignition Circuit:
Periodicallyinspect wires,spring contactand electrodes
for condition, security and proper spacing. (CAUTION:
10,000VOLTS)
Electrode Setting:
(See illustration below)
Electrodes Check : Periodically check wiring connections.
If necessary to adjust electrodes, use diagram.

10 HP SERIES OPERATOR’S MANUAL
Burner Nozzle:
Keep the tip free of surface deposits by wiping it with a
clean, solvent-saturated cloth, being careful not to plug
or enlarge the nozzle.For maximum efficiency, replace
the nozzle each season. Select nozzle size based on
the pressure washer you will be using:
Nozzle PressureWasher GPM
1.50 2 - 3
1.75 3 - 4
2.00 - 2.25 4 - 5
All nozzles should be 45°W
Fuel Control System:
The HP utilizes a fuel solenoid valve located on the fuel
pumpto controlthe flowof fuelto thecombustioncham-
ber.This solenoid, which is normally closed, is activated
by a flow switch when water is flowing through it.When
an operator releases the trigger on the spray gun, the
flow of water through the flow switch stops, turning off
thecurrent tothefuel solenoid.Thesolenoidthen closes,
shutting off the supply of fuel to the combustion cham-
ber. Controlling the flow of fuel in this way gives an in-
stantaneous burn or no burn situation, thereby eliminat-
ing high and low water temperatures, and combustion
smoke normally associated with machines incorporat-
ing a spray gun.Periodic inspection is recommended to
insurethat thefuel solenoidvalvefunctions properly.This
can be done by operating the machine and checking to
see that when the trigger on the spray gun is in the off
position, the burner is not firing.
Fuel Pressure Adjustment:
To adjust fuel pressure, turn the adjusting screw with a
5/32" Allen Wrench (located on the fuel pump) clock-
wise to increase, counterclockwise to decrease. Do not
exceed 200 PSI.
FIELD REPAIR INSTRUCTIONS
HP Fuel Pump:
1. Remove the13self tappingscrewswithrecess wash-
ers from the HP hood.
2. Remove louvered HP hood.(Item #22)
3. With a1/2" wrench,loosen (DO NOT REMOVE) the
two 5/16" - 18 x 1-1/2" serrated flange bolts that se-
cure the HP front panel.
4. With a 2.5 mm hex head wrench (Allen Wrench),
loosen the three set screws that hold the fuel pump
in the blower motor housing located on Idromatic
Boiler Assembly.
5. Carefully remove the fuel pump (Item #53) from the
blower motor, leaving the flexible zinc fuel line con-
nected, carefully bend the fuel line and fuel pump
away from the blower motor.
6. Locate the fuel pump/fan motor coupling.
7. Inspect the coupling for damage. The inside diam-
eter of fuel pump coupling requires flat on one side
to engage fuel pump, and the outside diameter re-
quires two male notches to engage the blower mo-
tor.
8. Perform a check to see if the fuel pump is turning
freely. Use an open end 7mm wrench or small ad-
justable wrench on fuel pump shaft.
9. Spin the fuel pump over in both directions using the
wrench for leverage. When the fuel pump is turning
freely (almost to the point you could turn it by hand)
it is ready to reinstall.
10. Align fuel pump coupler on pump shaft/fan motor.
Slide pump into fan motor. Secure pump with the
three set screws.
11. Test machine (make sure):
❑Blower motor spins
❑Fuel is on
❑Machine has power to it
❑Switch is on
❑Flow of water through machine
❑Thermostat is turned up
❑Flow switch is adjusted properly
12. When HP is operating properly, turn machine off,
tighten front panel, and install hood and 13 self tap-
ping screws with recess washers.
