INSTALLATION
Install a gas union in the gas line adjacent to and up-
stream 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.
Figure 1: Union Location
Union Connection
The following pipe sizes are just recommendations.
Always consult a local plumber and venting contrac-
tor for local codes and regulations during installation.
Pipe Sizing Chart for Natural Gas
The following chart is based on gas pressure in the
range 0-0.5 psi, specific gravity of 0.6 and pressure
loss of 0.5" W.C. Numbers are for straight schedule
40 pipe; fittings further reduce capacity. For example,
in 1" size, an elbow is equivalent to about 2.6 feet of
pipe and a tee is equivalent to about 5.2 feet of pipe.
Maximum capacity of pipe in cubic feet/hr of natural gas
(Multiply values by 1000 to get nominal BTU/hr capacity.
Place machine in a convenient location providing ample
support, drainage and room for maintenance (pgs 8-9).
Location:
The location should protect machine from damaging en-
vironmental 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 sourc-
es such as strong winds, freezing temperatures,
rain, etc.The machine should be located consider-
ing 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 machine.
2. It is recommended that a partition be made be-
tween 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.
Suffi cient combustion can only be obtained when
there is a suffi cient supply of oxygen available for
the amount of fuel being burned. If it is necessary
to install a machine in a poorly ventilated area, out-
side 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 mu-
nicipal officials regarding any specific code or regula-
tions 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 pip-
ing 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.

PRESSURE WASHER MANUAL
containers are equipped with a fixed liquid level gauge
which contacts the liquid level at 80% of container ca-
pacity, 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%.
Room Vents for 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 sup-
plied 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). See Figure 3.
NOTE: Air vents for combustion and ventilation
and exhaust flue sizing must conform to methods
outlined in current American Standard (ANSI-
Z223.1), National Fuel Gas Code of National
Standard of Canada CSA-149.1 and CSA-149.2
“Installation Code for Gas Burner Appliances”.
Exhaust Stack
The purpose of venting a gas-fired pressure washer is
to completely remove all products of combustion and
to vent gasses to the outside air without condensa-
tion in the vent or spillage at the draft hood (except in
cases of downdraft or poor stack conditions). Always
use strong, gas-tight, insulated pipe.
The design of this pressure washer depends on natural
draft (heat induced) to pull combustion gasses out of
the combustion chamber. The design of the exhaust
stack can have a significant impact on the proper
operation of the burner and coil.
During vent installation, avoid sharp turns, long hori-
zontal runs and improper pitches. Maintain proper sup-
port of vent connectors and joints, observe clearances
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.
Vents penetrating ceilings or walls should be double-
wall approved appliance vents and should be one to
INSTALLATION
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 pres-
sure 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) regulations
require periodic inspections and re-qualifications of
cylinders.DO NOT USE damaged or rusted containers.
DO NOT store LP-gas containers indoors or in en-
closed 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
transported, 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 cor-
rect 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 transport-
ing 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

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 com-
bustible 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 connec-
tion outlet of machine.
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
(Figure 4)
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.
See Figure 4.
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 contrac-
tor 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 li-
censed contractor who can calculate size, operation
connections and associated dampeners. Since we
are a manufacturer and not a licensed contractor and
as such we are unable to make recommendations for
suitable make and model of power vents and compli-
ance with local building codes.
Damper: An exhaust stack can reduce thermal ef-
ficiency 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.
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.
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.

PRESSURE WASHER MANUAL
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 sup-
ported 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 open-
ings 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.
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 com-
pletely, 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
individual shut-off valve must be disconnected from
gas supply piping system or damage to the gas valve
will occur.
Gas Pressure:
The incoming gas pressure must be a minimum of
9.0 wc-in and must not exceed 13.8 wc-in or ½ psig
to the control valve. Line pressure above ½ psig must
be regulated prior to the machine. The ideal supply
pressure is 13.0-13.5 wc-in. If the required BTU input
can not be achieved consult the factory for instructions
regarding changes to the nozzle orifice size and an
appropriate manifold setting.
NOTE: Any changes to the burner and manifold pres-
sure setting should only be performed by a trained
technician and adjusted using a flue gas analyzer.
The manifold pressure has been preset at the factory
according to the table below for optimum operation at
sea-level. The manifold pressure and BTU input will
be listed on the specification plate for the machine.
For Tech Tip Instructions
Combustion efficiency in a natural draft pressure
washer is significantly influenced by the heat created
inside the coil, the design of the coil and flue and the
length and diameter of the exhaust stack. The table
below shows data included in the operator’s manual
for flue and stack sizes and gas manifold pressure
settings. These sizes are critical for achieving proper
combustion and acceptable emissions.

Testing has shown that simply adding a 36” stack
extension to the flue adapter on top of the pressure
washer can reduce the outlet temperature by 5-10°F.
This occurs by inducing a higher pressure differential
at the exit of the coil and increasing the flow of air into
the combustion process and through the stack. Most
or all of the lost outlet temperature can be recovered
by installing and adjusting a damper in the stack.
However this adjustment must only be performed by
a trained technician using a combustion analyzer. An
adequate combustion analyzer can be purchased for
a little at $500 (Bacharach Fyrite Tech, Testo 310).
The analyzer must determine percent oxygen and/or
percent excess air as a minimum.
The damper should be installed 24-36” above the flue
adapter. The pressure washer can be operated safely
with the damper fully open but with the lower outlet
temperature. If the damper is closed too far there will
not be enough oxygen to burn all of the fuel. This will
cause higher and potentially dangerous levels of CO
in the flue gas emissions.
To adjust the damper for proper combustion and ef-
ficiency perform the following:
1. If there is no sample port for the analyzer probe,
drill a hole slightly larger than the combustion analyzer
probe through the exhaust stack at a point about 18”
above the flue adapter.
2. Insert the probe of the combustion analyzer so
that the tip is at the center of the stack.
3. Open the damper to the fully open position.
4. Start the pressure washer and allow it to heat up
for at least 20 minutes before making any adjustments.
5. Note the values for % Excess Air and/or % Oxygen.
6. Close the damper in small increments until %
Excess Air is between 20-30% and/or % Oxygen is
4-5%.

INSTALLATION
This process can also be used when turning down the
firing rate for high altitude installations above 2000 ft.
1. Adjust the gas pressure down 4% for every 1000
ft of elevation.
Example: Recommended firing rate for a 4.8@3000
is 4.2 wc-in. For an installation at 3500 feet reduce
this pressure by 16% by setting the manifold pressure
to 4.2*.84 = 3.5 wc-in.
A manometer capable of reading to at least the nearest
0.1 wc-in will be required for this adjustment. These
can be found for less than $200 (Extech HD700).
2. Follow steps 1-6 above to optimize the outlet
temperature of the pressure washer.
Installations Above 2000 ft:
Installation at altitudes greater than 2000 ft will require
adjustments to the gas manifold pressure.
For installations above 2000 feet the firing rate should
be reduced by 4% per 1000 feet. Example: Recom-
mended firing rate for a 4.8@3000 is 4.2 wc-in. For an
installation at 3500 feet reduce this pressure by 16%
by setting the manifold pressure to 4.2*.84 = 3.5 wc-in.
This adjustment should only be made by a properly
trained service technician. A manometer capable of
reading to the nearest 0.1 wc-in will be required for
this adjustment.
In Canada, certification for installation at altitudes over
4500 feet is the jurisdiction of local authorities.
Gas Valve Replacement:
If you replace your gas valve the manifold pressure for
the new valve will need to be adjusted to match the
specification plate for the machine. Follow the instal-
lation and adjustment instructions provided with your
replacement valve. A manometer capable of reading to
the nearest 0.1 wc-in will be required for this adjustmen
CAUTION: All gas conversion must be done by a
qualified service person in accordance with these
instructions and in compliance with all codes and
requirements. In Canada, gas conversion shall be
carried out in accordance with requirements of

Detergent
Valve
WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nau-
sea, fainting or poisoning.The
harmful elements may cause
property damage or severe
injury.
STEP 1: Use detergent designed
specifically for pressure wash-
ers. Household detergents could
damage the pump. Prepare de-
tergent solution as required by
the manufacturer. Fill a container
with pressure washer detergent.
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 1-2 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 solu-
tion 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.
