OPERATOR’S MANUAL
PRESSURE WASHER
6
Getting Started
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life and lower maintenance cost.
IMPORTANT: The use of a backflow preventer on
the water supply hose is recommended and may be
required by local codes.
The pressure washer should be run on a level surface
where it is not readily influenced by outside sources
such as strong winds, freezing temperatures, rain, etc.
The pressure washer should be located to assure easy
access for filling of fluids, adjustments and maintenance.
Normal precautions should be taken by the operator to
prevent moisture from reaching the pressure washer. It
is recommended that a partition be made between the
wash area and the pressure washer to prevent direct
spray from the wand coming in contact with the pressure
washer. Moisture reaching the equipment will reduce
the pressure washer’s service life. All installations
should comply with the local codes covering such
installations.
Venting
CAUTION: Some gases are heavier than air and will
spill out on the floor in the 2 to 3 minutes required
for the safety pilot valve to close off gas supply.
Therefore, always provide adequate space and ven-
tilation around these units.
CAUTION: All venting must be in accordance with
applicable federal and state laws, and local ordi-
nances. Consult local heating contractors.
IMPORTANT: This machine is not to be connected
to a type B gas vent. NE PAS RACCORDER CET
APPAREIL À UN TUYAU D’ÉVACUATION DE GAZ
DU TYPE B.
IMPORTANT: A draft diverter shall be installed.

If the pressure washer is to be used in an enclosed area,
a flue must be installed to vent burner exhaust to the
outside atmosphere. Exhaust gases should not be
vented into a wall, a ceiling, or a concealed space of a
building. Be sure the flue is the same size as the burner
exhaust vent on the pressure washer. Poor draft will
cause the pressure washer to soot and not operate
properly. When selecting the location for installation,
beware of poorly ventilated locations or areas where
exhaust fans may cause an insufficient supply of
oxygen. Proper 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
the machine in a poorly ventilated area, outside fresh
air may have to be piped to the burner and a fan installed
to bring sufficient air into the machine. Locate the
pressure washer so that the flue will be as straight as
possible and protrude through the roof at a proper height
and location to provide adequate draft. This gas fired
pressure washer must have a draft diverter installed in
the flue (available from most heating contractors). A draft
diverter will permit proper upward flow of exhaust flue
gases.
Water Supply
Connect water supply hose to the garden hose
connector. See Figure 1 for location. The water faucet
and supply hose must be capable of providing a
minimum of 2.2 gallons per minute (GPM).
Fuel Supply
CAUTION: Have a qualified gas serviceman install
and service your equipment.
WARNING: Gas line supply pressure must not ex-
ceed 14 water column inches (w.c.i.) (.50 PSI).
IMPORTANT: Gas line must be provided with a shut
off valve.
IMPORTANT: The gas supply must be able to sup-
ply a minimum of 245,000 BTU/HR at the machines
rated manifold pressure.
Consult building codes for installation requirements.
For proper and safe machine operation, we recommend
that a licensed contractor be consulted for machine
installation.
LP Vapor Fuel
The model 558 has been factory built to use LP vapor
fuel. DO NOT USE LIQUID FUEL.
Have a qualified gas serviceman install the LP vapor
fuel supply line to the machine. See Figure 5 for location
of gas inlet.
