26. Exhaust gases should not be vented into a wall, a
ceiling or a concealed space of a building. Adraft
diverter must be installed to prevent down draft and
to allow cooling of exhaust temperatures. Down
draft diverters shall be
installed in the vents and located at a distance from
the pressure washer stack to achieve maximum
draft of 36" minimum. Exhaust gases that exceed
470°F (243°C) are not suitable for connection to
Type B gas vents.
Example of Down Draft Diverter for Gas Fired
Machines
WARNING: Do not spray machine
or any people, animals, or elec-
trical parts.
Follow the maintenance instructions
specified in the manual.
Propane Tank Safety Instructions
CAUTION: Only qualified persons should fill your
LP-gas containers.
1. Never allow your LP-gas container to be filled
above the maximum safe level as indicated by a
scale or the fixed liquid level gauge (outage). Do
not use the visible gauge for filling.
2. Do not use a wrench or pliers to close the service
valve or fixed liquid level gauge. These valves are
designed to be closed leak-tight by hand or screw-
driver as appropriate. If wrenches are necessary to
stop a leak, the valve needs repair or replacement.
3. When tightening the POL Nut (left hand thread) on
the service valve, draw it up snug with a proper
wrench. This is a machined male brass fitting
which seats securely against a female seat in the
POL valve – no pipe dope is necessary. Acme/
Type 1 valves have right handed threads which are
secure when hand tight, and on the Quick Discon-
nect/Type 2 Valves, the male connection is
inserted into the female connection on the cylinder
valve. (No wrenches required for both theAcme
and the Quick Disconnect.)
4. When using container, slowly open service valve
all the way. Listen to the regulator. A continuous
hiss may indicate a leak or an open valve on an
appliance.
5. Check all tank and the line connections periodically
to be sure they are tight. When testing for leaks,
use approved leak detector solution – not matches.
6. Make certain your container is properly fastened in
place.
7. Turn container with open part of container guard
towards frame. This protects valves and regulator
against flying rocks and mud. Transport container
in the proper position in which it is used, with the
valves closed and POL Plugs inserted for POL
Valves or Dust Caps for Acme Valves. Secure the
tank against falling or rolling.
8. Check for leaks after connecting.Apply approved
leak detector solution to connection, turn off all
burners and pilots, and open service valve. Leaks
will be detected by the growth of the bubbles. If
bubbles grow, tighten or repair the connection as
needed. Repeat leak test until problem is
corrected.
9. LP-gas is normally non-corrosive – you need not
worry about the inside of your container. However,
the outside should be kept free from rust by a
periodic coat of paint in a light reflective color. It is
very important to inspect and maintain the bottom
and foot ring on the container.
10. Do not store LP-gas containers indoors or in
enclosed areas. Do not expose LP-gas container
to heat. Always store with service valve closed and
plugged as required.
11. Do not attempt to repair any containers, container
valves, regulator or appliances by yourself. Use
only trained certified LP-gas service personnel to
perform repairs.

Operations
Installation
Place machine in a convenient location providing
ample support, drainage and room for maintenance.
Location
The location should protect machine from damaging
environmental conditions, such as wind, rain and
freezing.
1. The machine should be run on a level surface
where it is not readily influenced by outside
sources such as strong winds, freezing tempera-
tures, rain, etc. The machine should be located
considering accessibility for the replacing of
components and the refilling of detergents, adjust-
ments and maintenance. Normal precautions
should be taken by the operator of the machine to
prevent excess moisture from reaching the
machine.
2. It is recommended that a partition be made
between the wash area and 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 ade-
quate).
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 regu-
lations governing the installation. The installation must
conform to local codes (NFPA 54).
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.
Gas Piping
This machine shall be rigidly connected to the gas
piping outlet and equipped with external manual shut-
off valves adjacent to such machine.All gas piping shall
be approved and installed in accordance with the
Uniform Mechanical Code.
Install a gas union in the gas line adjacent to and
upstream from the control manifold and downstream
from the 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.

gas (Multiply values by 1000 to get nominal BTU/hr
capacity.
LP-Gas (Liquid petroleum gas or propane)
LP-gas is gas compressed into liquid form for easy
transportation and storage. It is also known as propane
or bottle gas. (Propane tanks are not supplied with this
equipment.)
LP-gas is flammable, is always contained under
pressure and the liquid can freeze skin. Therefore, in
the interest of safety, it is important to understand the
basic facts about LP-gas and LP-gas containers.
Federal DOT (Department of Transportation) regula-
tions require periodic inspections and re-qualifications
of cylinders. DO NOT USE damaged or rusted
containers.
DO NOT store LP-gas containers indoors or in
enclosed areas. Do not expose LP-gas container to
heat. Always store with service valve closed and
plugged as required.
CAUTION: Use LP-gas containers in proper
position.
Most LP-gas pressure washer heaters are designed to
operate on LP-gas vapor only. Therefore, all LP-gas
containers designed for vapor service must be trans-
ported, installed and used in the proper position. Do not
transport, install or use a vertical cylinder in a horizontal
or upside down position. Proper care must be taken to
position a horizontal container in the correct position for
vapor withdrawal. Liquid LP-gas could enter the
system designed for vapor only, possibly creating a
hazardous condition.
Always use a POL plug installed on a POL valve or a
dust cap on an ACME/Type 1 valve when transporting
or storing disconnected containers (full or empty).
Check for leaks after connecting.Apply approved leak
detector solution to connection, turn off all burners and
pilots and open service valve. Leaks will be detected by
the growth of bubbles. If bubbles grow, tighten or repair
the connection as needed. Repeat leak test until
problem is corrected.
Check all tank and the line connections periodically to
be sure they are tight. When testing for leaks, use
approved leak detector solution — not matches.
Improved Regulation: The second stage regulator
receives a relatively uniform pressure from the first
stage regulator. This helps the second stage regulator
to maintain appliance pressure at a nearly constant 11"
W.C.
Filling the LP-Gas Container
Only qualified persons should fill your LP-gas
containers.
CAUTION: Overfilling is hazardous!
DO NOT allow your LP-gas container to be overfilled.
Stop filling when liquid appears at the fixed level gauge.
Bleed off excess propane in a safe area. Most LP-gas
containers are equipped with a fixed liquid level gauge
which contacts the liquid level at 80% of container
capacity, allowing 20% for expansion. LP-gas
containers not equipped with a fixed liquid level gauge
can only be filled by weight.
In cold climates, in order to keep vaporization of LP-gas
at the highest level, keep the fuel levels above 50%.
Propane Tank Disposal:
Propane tanks present a real danger in the waste
stream, so it is essential to properly dispose of old
tanks so they do not injure you or sanitation workers.
The best way to dispose of unused propane tanks is by
calling a propane company to pick it up. Propane tanks
are not picked up by garbage collectors, and improper
disposal is illegal in some areas. If a propane tank is
unfit for service, one should contact a propane
company.

Operations
Combustion and Ventilation Air
Properly sized vents are vital for the safe and efficient
operation of a pressure washer installed in a confined
space. When combustion and ventilation air are
supplied from inside the building, each opening must
have an area of one square inch for every 1,000 BTUH
input. When combustion air is supplied from the
outside, each opening must have an area of one
square inch for every 2,000 BTUH for horizontal ducts
and one square inch for every 4,000 BTUH for vertical
ducts (refer to NFPA 54).
The purpose of venting a gas pressure washer is to
completely remove all products of combustion and to
vent gasses to the outside air without condensation in
the vent or spillage at the draft hood (except in cases of
downdraft or poor stack conditions). To assure correct
venting, use a strong, gas-tight insulated pipe with a
cross section equal to that of the flue collar or draft
hood outlet and of sufficient vertical height.
During vent installation, avoid sharp turns, long hori-
zontal runs and improper pitches. Maintain proper
support of vent connectors and joints, observe clear-
ances from all combustibles and top the vent outlet with
an approved cap.
Type “B”, due to its temperature rating, can only be
used with natural draft pressure washers. A“B” vent is
designed for exhaust temperatures not to exceed
470°F (245°C).
All venting installations must conform to local codes. In
the absence of local codes, refer to “National Fuel Gas
Code” NFPA 54 and be constructed of materials
approved by the Uniform Building Code.
The pressure washer includes a collar that will mate
with standard HVAC ducting. The user will be respon-
sible for installation of an exhaust stack. The exhaust
stack should include a Draft Diverter/Inducer, Damper,
Sampling Port and Rain Cap. An adapter can be
installed between the collar and stack to adjust the
diameter from 10” to 8” or 12” to 10”.
Size the stack according to the following (see also
applicable local and national standards regarding
installation of gas-fired appliances):
• 3.5 to 4.4 gpm 10” Collar 8” Stack
• 4.5 to 5.5 gpm 10” Collar 10” Stack
• 6.3 gpm 12” Collar 10” Stack
• 8 – 10 gpm 12” Collar 12” Stack
Draft Diverter/Hood The draft required to vent
combustion gases is created by the heat inside the
pressure washer coil.A draft diverter helps improve
draft into the stack without pulling more air through the
combustion box and decreasing combustion efficiency.
The draft diverter can also help prevent back drafting
that can inhibit combustion.The draft diverter should be
installed a minimum of 36” above the flue collar.
Power Vent (Draft Inducer) If this machine is going to
be installed on a 90° or extended exhaust vent run
length which may restrict air flow it is recommended
that a contractor install a power vent. When a
contractor has found it impossible to vent straight
through the roof power venting is recommended to
help eliminate exhaust restriction of this natural draft
machine. This draft inducer (power vent) must be
installed by a licensed contractor who can calculate
size, operation connections and associated damp-
eners. Since we are a manufacturer and not a licensed
contractor and as such we are unable to make recom-
mendations for suitable make and model of power
vents and compliance with local building codes.
Damper An exhaust stack can reduce thermal effi-
ciency by drawing in too much combustion air. This can
be controlled by adding a damper just below the draft
diverter. 8.753-473.0 - 8" Damper, 8.753-474.0 -10"
Damper, 8.753-418.0 - 12" Damper.
NOTE: Closing the damper can create high levels of
CO in the exhaust. Adjustments to the damper should
only be performed by a trained technician using a flue
gas analyzer. If an analyzer is not used the damper
should be set in the fully open position.

Operations
Sampling Port A port for sampling flue gases and
measuring the flue gas temperature should be placed
18” above the flue collar. The port should be covered
when sampling is not being performed. The size of the
port should be only slightly larger than the probe for the
flue gas analyzer.
Rain Cap A rain cap should be installed on top of the
stack to prevent rain water, leaves and debris from
entering the stack. Your installer may also recommend
specialty caps for high wind areas or cold weather
zones to help prevent back drafting. 8.717-731.0 - 10"
Raincap, 8.717-732.0 - 12" Raincap
Vents penetrating ceilings or walls should be double-
wall approved appliance vents and should be one to
two inches from combustibles. Vents passing through
enclosed spaces and vents exposed to the weather
should also be the double-wall type. Sometimes vents
have to be built of such great length that they come
apart at their joints under their own weight. These
should be screwed together at the joints with sheet
metal screws, usually three per joint. If the inspector
indicates that the vent is too close to combustibles, it
may be necessary to chisel away some of the combus-
tible or route the vent pipe around the combustible. The
cross-sectional area of any flue shall not be less that
the cross-sectional area of the flue vent connection
outlet of machine.
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.
High Pressure 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 canescape 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.
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 pressure washer and its indi-
vidual shut-off valve must be disconnected from gas
supply piping system or damage to the gas valve will
occur.
Gas Pressure
The ideal incoming gas pressure is 11 w.c.i (water
column inches). Minimum is 9 w.c.i., maximum is 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.
The gas pressure coming out of the regulator and going
to the burner ring has been factory set for elevations of
0 to 2000 ft. Altitudes greater than 2000 ft will require
adjustments to the gas manifold pressures. Consult
your local service dealer for high altitude adjustments.
In Canada, certification for installation at altitudes over
4500 feet above sea level is the jurisdiction of local
authorities. You should not readjust the burner ring gas
pressure. If you replace your gas valve, you will need to
adjust the new valve. Refer to your machine’s specifi-
cation plate for the correct pressure setting. Follow the
installation and adjustment instructions provided with
your replacement valve.
NOTE: Air for combustion and ventilation along with
exhaust flue sizing mustconform to methods outlinedin
current American Standard (ANSI-Z223.1) National
Fuel Gas Code or National Standard of Canada CSA-
149.1 and CSA-149.2 “Installation Code for Gas
Burning Appliances”.

Applying Detergent &
General Operating Techniques
WARNING: Some detergents may
be harmful if inhaled or ingested,
causing severe nausea, fainting or
poisoning. The harmful elements
may cause property damage or
severe injury.
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could damage
the pump. Prepare detergent solution
as required by the manufacturer. Fill a
container with pressure washer deter-
gent. Place the filter end of detergent
suction tube into the detergent
container.
STEP 2: Open detergent valve counterclockwise until
you obtain desired mixture. Detergent will mix with the
high pressure water stream.
STEP 3: With the motor running,
pull trigger to operate machine.
Liquid detergent is drawn into the
machine and mixed with water.
Apply detergent to work area. Do
not allow detergent to dry on
surface.
IMPORTANT: You must flush the detergent from
your pressure washer after each use by placing the
suction tube into a bucket of clean water, then run
the pressure washer for 2 minutes.
NOTE: If you remove detergent siphon tube from
container or allow container to empty, it will cause low
pressure by sucking air, which will damage the pump.
Thermal Pump Protection
If you run the engine for 3-5 minutes without pressing
the trigger on the spray gun, circulating water in the
pump can reach high temperatures. When the water
reaches this temperature, the pump protector engages
and cools the pump by discharging the warm water
onto the ground. This thermal device prevents internal
damage to the pump.
Cleaning Tips
Pre-rinse cleaning surface with fresh water. Place
detergent suction tube directly into cleaning solution
and apply to surface. For best results, limit your work
area to sections approximately 6 feet square and
always apply detergent from bottom to top.Allow
detergent to remain on surface 1-3 minutes. Do not
allow detergent to dry on surface. If surface appears to
be drying, simply wet down surface with fresh water. If
needed, use brush to remove stubborn dirt. Rinse at
high pressure from top to bottom in an even sweeping
motion keeping the spray nozzle approximately 1 foot
from cleaning surface. Use overlapping strokes as you
clean and rinse any surface. For best surface cleaning
action spray at a slight angle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern
and distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
extreme caution as pressure washer may
remove the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash
a small area, then check the surface for
damage. If no damage is found, continue to
pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will
damage the surface being cleaned.
Rinsing
Turn detergent valve clockwise to close. Operate
pressure washer and allow a few seconds for the
detergent to clear.
