Getting Started
IMPORTANT: Proper initial installation of equipment will assure more satisfactory performance, longer service life and lower maintenance cost.
WARNING: If connection is made to a potable water system, the system shall be protected against backflow. 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.

CAUTION: All venting must be in accordance with applicable federal and state laws, and local ordinances. Consult local heating contractors.
NOTE: This product is labeled of outdoor use only and should be operated outdoors. It is not recommended to operate indoors. If under certain conditions that make it impossible to operate outdoors you can operate indoor using a hood vent or venting. Venting can cause restriction of air flow through the combustion chamber causing excessive soot. Use a larger vent size then the exhaust stack to prevent restriction and contact the local servicing dealer to adjust the air mixture after installation of vent.

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.

ATTENTION: Toute la ventilation doit être conforme aux lois fédérales et de l’État ou de la province, et aux réglementations locales applicables. Consulter des entrepreneurs en systèmes de chauffage locaux.
PRECAUCIÓN: Toda la ventilación debe ser de acuerdo con las leyes federales y estatales aplicables y las ordenanzas locales. Consulte a contratistas locales de calefacción.
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. See Component Identification 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

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.
