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.

manual main shut-off valve. A 1/8" NPT plugged tapping
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.
