for extensive periods of time as this may cause dam-
age to the pump.
13. Protect from freezing.
14. Be certain all quick coupler fittings are secured
before using pressure washer.
15. Do not allow acids, caustic, or abrasive fluids to pass
through the pump.
16. Inlet water must be from a cold, fresh city water

pane fuel. Do not use liquid fuel. Have a qualified
serviceman install and service your equipment.
22. Never expose a spark or flame where there may be
unburned gas present.
23. Some gases are heavier than air and will spill out on

WARNING - RISK OF EXPLOSION: Do not spray flam-
mable liquids or operate machine in areas where flam-
mable vapors are present. Operate only where open
flame or torch is permitted.
CAUTION - RISK OF ASPHYXIATION: Do not run
machine indoors or in an enclosed area without the
required venting, as exhaust fumes may be hazardous
to your health.
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 ventilation around
these units.
IMPORTANT: A draft diverter shall be installed.

IMPORTANT: 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 exhaust to the outside
atmosphere. Exhaust gases should not be vented into a
wall, a ceiling, or into a concealed space in 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 loca-
tions 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. See
figure
5
for details. A draft diverter will permit proper upward flow
of exhaust flue gases.
