Venting

CAUTION: All venting must be in accordance with ap-

plicable 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. Be sure the flue is the same size

as the burner exhaust vent on the pressure washer lid.

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.

Burner Air Adjustment: The oil burner on this machine is

preset for operation at altitudes below 500 feet. If operated

at higher altitudes, it may be necessary to adjust the air

band for a #1 or #2 smoke spot on the Bacharach scale.

To adjust, start machine and turn burner ON. Loosen two

locking screws found on the air band and close air band

until black smoke appears from burner exhaust vent. Note

air band position. Next, slowly open the air band until white

smoke just starts to appear. Turn air band halfway back

to the previously noted position. Tighten locking screws.

For higher altitudes, the air band opening may need to

be increased; for lower altitude, the .air band may need

to be decreased.

For higher humidity, the air band opening may need to be

increased; for lower relative humidity, the .air band may

need to be decreased.

For higher ambient temperatures the air band opening may

need to be increased; for lower ambient temperatures, the

air band opening may need to be decreased.

Adjust to your operating location's environment as-needed

for best smoke spot and performance compliant with local,

state, and federal regulations.
