fi cient 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
provided to the machine. Locate the pressure washer so
that the fl ue will be as straight as possible and protrude
through the roof at a proper height and location to provide
adequate draft. This oil fi red pressure washer must have
a draft regulator installed in the fl ue (available from most
heating contractors). A draft regulator will permit proper
upward fl ow of exhaust fl ue gases.
To adjust:
start machine and turn burner ON. Loosen
two locking screws found in the air shutter openings
(refer to
fi gure 3
) and close air shutter until black
smoke appears from burner exhaust vent. Note air band
position. Next, slowly open the air shutter until white
smoke just starts to appear. Turn air shutter halfway
back to the black smoke position previously noted.
Tighten locking screws.
If the desired position cannot be obtained using only
the air shutter, lock the air shutter in as close a position
as can be obtained, then repeat the above procedure
on the air band setting.
CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation, discontinue
use and readjust air bands.
NOTE: If a fl ue is installed, have a professional ser-
viceman adjust your burner for a #1 or #2 smoke spot
on the Bacharach scale.
For additional burner component information, see
Burner Assembly
. It is recommended that the oil
burner be serviced yearly or as needed. Contact your
local service center.
