machine should be located considering accessibility for the replacing of components and the refilling
of detergents, adjustments and maintenance. Normal precautions should be taken by the operator of
the machine to prevent excess moisture from reaching the power unit or electrical controls.
2. It is recommended that a partition be made between
the wash area and the machine to prevent direct
spray from the spray gun from coming in contact with
the machine. Excess moisture reaching the power
unit or electrical controls will reduce the machine’s
life and may cause electrical shorts.
3. During installation of the machine, beware of poorly
ventilated locations or areas where exhaust fans may
cause an insufficient supply of oxygen. Sufficient
combustion can only be obtained when there is a
sufficient supply of oxygen available for the amount
of fuel being burned. If it is necessary to install a
machine in a poorly ventilated area, outside fresh
air may have to be piped to the burner and a fan
installed to bring the air into the area.
4. 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 should be adequate).
WARNING: Avoid small areas or near exhaust fans.
Gas Codes:
Confer with local gas company and with proper municipal officials regarding any specific code or regulations
governing the installation. The installation must conform
to local codes.
Electrical:
The machine, when installed, must be electrically
grounded in accordance to local codes. Check for proper
power supply using a volt meter; check the serial plate
for the correct requirements.

accessible for test gauge connection shall be installed
immediately upstream of the gas supply connection for
the purpose of determining the gas supply pressure to
the burner, and to prevent damage to gas valve.
If a manual gas shut off valve is not in the gas supply line
within six feet of the machine and in an accessible location, one shall be installed.

NOTE: If the flue pipe exceeds 10 ft. in length, or contains more than two elbows, use next size larger pipe
and draft hood or the burner will not ignite. No movable
flue pipe damper should be used on any installation.
Draft Diverter:
Install the draft diverter above the heating coil. The
diverter enhances the draft through the burner by severing the chimney effect created in sections of furnace pipe
positioned below. It also helps prevent freezing of the
coil due to wind chill factors.

Venting:
If the machine is used indoors, regulations or ventilation
concerns may call for a chimney or furnace pipe.
When venting the machine, if the machine is to be in an
enclosed area with a chimney on it, be sure the chimney
is the same size as the stack on the machine. Poor draft
will cause the machine to soot and not operate efficiently.
When placing the machine for installation, position the
stack to be as straight as possible and to protrude through
the roof of the building at a proper location and at sufficient height to eliminate down-draft. The chimney of a
gas fired machine shall be installed with a down-draft
diverter located about 3 ft. above machine.
When the heating appliance is installed in a tightly closed
room without ventilation openings to the outdoors or other
rooms, provisions shall be made for supplying air for combustion through special openings, one near the floor line
and the other near the ceiling, each to be sized on the
basis of one square inch or more of free area for each
1,000 BTU input per hour (see Figure 4).
When a room is of unusually tight construction and has
a kitchen and/or bathroom ventilating fan, which may be
used for exhausting air outdoors -or has a vented fireplace — it is recommended that combustion air be supplied to the enclosed room through intakes extending to
the outside of the building and terminating in down-turned
fittings. These should be suitably arranged to prevent obstruction from snow or rain, and include a protecting
screen not smaller than 1/4 inch mesh.

to supply air for combustion when installed
in an enclosed room.
Water Source:
The water source for the machine should be supplied by
a 5/8" I.D. garden hose with a city water pressure of not
less than 30 PSI. If the water supply is inadequate, or if
the garden hose is kinked, the machine will run very rough
and the burner will not fire.
Water Connection:
Connect the high pressure hose by pulling the coupler
collar back and then inserting it onto the discharge nipple.
Secure it by pushing the collar forward.
Attach the wand into the spray gun using teflon tape on
the pipe threads to avoid leaks.
Inspection and Testing Gas Piping:
The building structure should not be weakened by installing the gas piping. The piping should not be supported by other piping, but should be firmly supported
with gas hooks, straps, bands or hangers. Butt or lap
welded pipe should not be run through or in an air duct
or clothes chute.
Before turning gas under pressure into piping, all openings from which gas can escape should be closed. Immediately after turning on gas, the system should be
checked for leaks. This can be done by watching the 1/2
cubic foot test dial for 5 minutes for any movement or by
soaping each pipe connection and watching for bubbles.
If a leak is found, make the necessary repairs and repeat the above test.
Shark HNG • Rev. 2/03a
Defective pipes or fittings should be replaced and not
repaired. Never use a flame or fire in any form to locate
gas leaks — use a soap solution.
After the piping and meter have been checked completely,
purge the system of air. DO NOT bleed the air inside an
enclosed room.
During pressure testing of the system at test pressures
in excess of 1/2 PSIG, the appliance and its individual
shut-off valve must be disconnected from the gas supply piping system or damage to the gas valve will occur.
Gas Pressure:
The ideal incoming gas pressure is 11 water column
inches or w.c.i. (minimum 9 w.c.i, maximum 14 w.c.i. or
1/2 PSIG). The correct operating manifold pressure for
natural gas is 3.5 w.c.i. The operating manifold pressure
for propane gas is 10 w.c.i. By adjusting the gas valve
pressure regulator between 3 and 4 w.c.i. a side range
can be achieved for natural gas.
If the desired input rating cannot be obtained within the
above manifold pressure adjusting range, then the next
size larger or smaller burner orifice should be used.

and dry.
The areas around the Shark washer should be kept clean
and free of combustible materials, gasoline and other
flammable vapors and liquids.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
GENERAL WASHING
TECHNIQUES
If dirt comes off relatively easy and no grease and oil are
present, cleaning with cold water will normally suffice.
However, when grease and oil are present, hot water
will greatly speed up the process.
Clean with the spray nozzle a foot or so from the surface
being cleaned. For more difficult cleaning, move the
nozzle in closer.
Shark HNG • Rev. 2/03a
Page 13
HNG SERIES PRESSURE WASHER
OPERATOR’S MANUAL
13
If the machine is equipped with a shut-off spray gun and
various nozzle patterns, use the wide patterns for easy
soil removal jobs and the narrow patterns on the more
difficult jobs or for tight areas such as cracks and holes.
In most cases, faster results and better detergent
economy is obtained by applying the detergent and letting it “set” for a few minutes, prior to rinsing. This enables the detergent to do its soil penetrating and loosening work.
Most cleaning work terminates with a high pressure rinse
as part of the normal cleaning procedure. In some cases,
however, the last operation may be application of a detergent (sanitizing, for example). After such work, run
the machine for 20-30 seconds to clear pump and lines.
MAINTENANCE AND SERVICE
Spray Nozzles:
Each machine is equipped with one or more spray
nozzles, depending on the model. Different spray nozzles
are calibrated for each machine, depending on the flow
and pressure of that particular model. Spray nozzles vary
in bore size and angle of spray. Popular spray angles are
0°, 15°, 25°, 40°. When ordering, please specify size and
angle of nozzle. Nozzle size for each machine is located
on the serial plate.
Unloader Valves:
Unloader valves relieve pressure in the line when a spray
gun is closed. Unloader valves are preset and tested at
the factory before shipping. Occasional adjustment of
the unloader may be necessary to maintain correct pressure. For valve adjustment contact your nearest Shark
dealer or call Shark technical support.
Winterizing Procedure:
Damage due to freezing is not covered by warranty.
Adhere to the following cold weather procedures whenever the washer must be stored or operated outdoors
under freezing conditions.
It is necessary to protect your machine against freezing
when temperatures drop below 32° F. Siphoning a small
amount of antifreeze into the system is recommended.
This is done by pouring a 50-50 mix of antifreeze and
water into the float tank and then siphoning 100% antifreeze through the detergent line with the pump on. If
compressed air is available, an air fitting can be screwed
into the float tank strainer fitting, and by injecting compressed air, all water will be blown out of the system.
The use of a draft diverter will prevent the wind chill factor from freezing the coil.
Shark HNG • Rev. 2/03a
Low Pressure Diagnosis:
(Machines with spray gun)
Refer to Troubleshooting Chart for low pressure. If the
trouble is found to be either the unloader or the pump,
your next step is to determine which is the problem. This
can be done by eliminating the unloader from the system and attaching the 50' discharge hose directly to the
pump. If high pressure is developed in this manner, the
pump is good and the unloader needs to be repaired or
replaced. If low pressure is still present, then the pump
needs repairing.
CAUTION: When using this procedure to test components keep the spray gun open at all times.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with an adjustable
thermostat. In the event the temperature of the water
should exceed its operating temperature, the thermostat will turn the burner off until the water cools.
Pumps:
Use only SAE30 weight non-detergent oil. Change oil
after first 50 hours of use. Thereafter, change oil every
three months or at 500 hour intervals. Oil level should be
checked through use of the dipstick found on the top of
the pump or by the red dot visible through the oil gauge
window. Oil should be maintained at that level.
HEATING COILS
To Check Water Heater Coil for Leaks:
With the main burners "OFF" start the pumping unit and
allow it to run for a few minutes. With a drop light or flashlight check the burner compartment. If no leaks are visible, and water is dripping from the coils then it is condensation from the flue gases when the burners are on.
Condensation from Heating Coil:
When cold water is being pumped into the water heater
coils, and the burners are on, condensation will form on
the coils and drip down into the burner compartment,
giving the appearance of a leaking coil, particularly on
cold humid days.
Deliming Coils:
In alkaline water areas, lime deposits can accumulate
rapidly inside the coil pipes. This growth is increased by
the extreme heat build up in the coil. The best prevention
for liming conditions is to use high quality cleaning detergents. In areas where alkaline water is an extreme
problem, periodic use of Shark Deliming Powder (part
#9-028008) will remove lime and other deposits before
coil becomes plugged. (See Instructions below for use
of Shark Deliming Powder.)

HNG SERIES PRESSURE WASHER
OPERATOR’S MANUAL
Periodic flushing of coils is recommended.
1. Fill a container with 4 gallons of water, then add 1 lb.
of deliming powder. Mix thoroughly.
2. Remove nozzle from spray gun assembly and put
spray gun into container. Secure the trigger on the
spray gun into the open position.
3. Attach a short section (3-5 ft.) of garden hose to
machine to siphon solution from an elevated container, or add mixture to the float tank. Turn pump
switch on allowing solution to be pumped through
coils and back into the container. Solution should be
allowed to circulate 2-4 hours.
4. After circulating solution, flush entire system with
fresh water. Reinstall wand assembly to spray gun.
Gas Valve Regulator Adjustment:
(See Fig. 5)
Adjustment of the built-in regulator isn’t normally necessary, since it is preset at the factory. However, field adjustment may be accomplished as follows:
1. Attach manometer at pressure tap port.
2. Remove regulator adjustment screw cap.
3. With small screwdriver, rotate adjustment screw
clockwise to increase or counterclockwise to decrease gas pressure.
4. Replace regulator adjustment screw cap.

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
the disk ruptures, it will need to be replaced. Torque to

PROPANE GAS (Vapor Fuel Only)
General Safety Precautions:
Have a qualified gas service person assist in any gas
burner installation or service. Few maintenance people
or mechanics are knowledgeable in gas controls or related safety practices. Since propane gas is heavier than
air, unburned propane gas will gravitate to the floor rather
than rise out of the stack. Hence, adequate floor space
and good ventilation are especially important with propane systems.
Shark HNG • Rev. 2/03a
Page 15
HNG SERIES PRESSURE WASHER
OPERATOR’S MANUAL

Gas Pressure Requirements:
All propane fired machines operate on gas phase only.
They are designed to operate at a pressure of 11 w.c.i.
(between 1/3 and 1/2 of one PSI), and are often operated at even higher pressures when extra heat is needed.
Exterior regulators are needed to control the system. Propane bottles are not included with the machine. A high
pressure regulator should be installed on the propane
bottle and a low pressure regulator attached to the pressure washer.
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.
If the water heater will be exposed to freezing weather,
an antifreeze solution should be circulated through the
coils by whatever means are available for the particular
system the water heater is used on.
BURNER TROUBLESHOOTING
Millivolt System Check:
This machine has a thermopile self-powered combination gas control. Before checking the millivolt system,
the following operations should be performed and observations made:
1. Inspect system for proper wiring.
2. The switch leads and all wire connections should be
cleaned and tightened to eliminate all unnecessary
resistance.
3. Clean and/or adjust pilot for maximum flame impingement on the thermopile.
4. If pilot will not remain lit when gas cock dial is released, check automatic pilot (Step D).
The millivolt system and individual components may be
checked with a DC millivolt meter having a 0-1000 MV
range. Conduct each check as shown in the chart below
by connecting the meter test leads to terminals as indicated. All readings are closed circuit.
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:
Because condensation from heater coils may drip down
on the burners, scale buildup 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. (Remove
the nuts from the U-bolts, item 28 on page 23). Slide
burner manifold out through shell opening.
2. TO CLEAN BURNER JETS:
Select proper size drill for type of gas involved. Use
vise to hold drill and to ream out each jet orifice.

C. System Resistance Check
(“C” Reading = Switch contacts CLOSED - Gas Cock
“ON” - Main burner should be ON)
If the “C” Reading is more than that specified
for the system being checked, this indicates the
resistance in the system is excessive and must
be reduced. To correct:
a. Clean and tighten switch leads and connec-
tions.
b. Shorten switch lead wires and/or replace
with heavier gauge wire.
c. Cycle switch rapidly to clean contacts.
D. Automatic Pilot Dropout Check
1. Hold gas cock dial depressed in pilot position until maximum output is observed. Then extinguish
pilot and observe meter.
2. Dropout of automatic pilot magnet (sound should
be audible) should occur between 120 millivolts
and 30 millivolts. If dropout occurs outside these
limits, change the automatic pilot magnet assembly.
A. Complete Millivolt System Check
(“A” Reading = Switch contacts CLOSED - Gas
Cock Dial “ON” - Main burner should come ON).
1. If the reading is more than 100 millivolts and the
automatic valve still does not come on, replace
the automatic valve operator.
2. If the closed circuit reading (“A” Reading) is less
than 100 millivolts, determine cause for low reading - proceed as follows:
B. Thermopile Output Reading Check
(“B” Reading = Switch contacts OPEN - Main burner
OFF).
If the minimum 250 millivolt reading is not obtainable, readjust pilot for maximum millivolt output.
If millivolt reading is still below minimum specified, replace thermopile.

PRESSURE EQUIVALENTS
Simply stated, pressure is the force exerted by a gas or liquid attempting to escape from a container. It is useful to
know how strong this “attempt to escape” is. Pressure can be measured with a manometer or with a pressure gauge.
At the lower levels, it is expressed in “water column inches” i.e. 11 w.c.i. Higher pressures are expressed in terms of
the force exerted against a square inch of area, for example, 125 lbs. per square inch (125 psi).
