Installation Instructions
Venting
DANGER: Do not run machine indoors or in an enclosed area without adequate ventilation, or in areas where flammable vapors, (gasoline, solvents, etc.) may be present. Do not vent exhaust gases into a wall, a ceiling, or a concealed place.
CAUTION: All venting must be in accordance with applicable state and federal 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 a unit 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 unit. Locate the pressure washer in such a manner 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 unit must have a draft controller installed in the flue. A draft controller will permit proper upward air flow of exhaust flue gases.

1.) Turn the engine and heat switches ON (Refer to “Operation” for details). Have someone operate the spray gun so the burner fires.
2.) Loosen the locking screw and close the air band until black smoke appears from the burner exhaust vent. Note the position of the white arrow on the air band.
3.) Slowly open the air band until white smoke just starts to appear.
4.) Turn the air band half way back to the black smoke position previously noted. Tighten the locking screw.
5.) Fine tune the burner air by loosening the shutter lock screw and turning the shutter until the exhaust is cleanest. Tighten the shutter lock screw.
