INSTALLATION
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 code.
The pressure washer should be run on a level surface
and in a protected area where it is not readily influenced
by outside forces 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
DANGER: Do not operate machine in areas where
flammable vapors (gasoline, solvents, etc.) may be
present, as this machine may ignite the vapors.
CAUTION: All venting must be in accordance with
applicable federal and state laws, and local ordinances. Consult local heating contractors.
If the pressure washer is to be used in an enclosed area,
a flue must be installed to vent burner and engine exhaust
to the outside atmosphere. Be sure the flue is the same
size as the burner exhaust vent on the pressure washer.
See Figure 1 for location. 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
oil fired pressure washer must have a draft regulator
installed in the flue (available from most heating
contractors). A draft regulator will permit proper upward
flow of exhaust flue gases.
In addition, the pressure washer should never be operated
in an enclosed area where high ambient temperatures
exist. High ambient temperatures (above 100
cause engine oil failure and will greatly reduce the engine’s
performance.
