Installation Instructions - Hotsy 1467SS Operator's Manual

Venting
CAUTION - RISK OF ASPHYXIATION: Do not run
machine indoors or in an enclosed area without the
required venting, as exhaust fumes may be hazard-
ous to your health.
CAUTION: All venting must be in accordance with ap-
plicable federal and state laws, and local ordinances.
Consult local heating contractors.
IMPORTANT: A draft regulator shall be installed.
INSTALLER UNE HOTTE DE TIRAGE.
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. 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 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 suf-
ficient 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.
Oil Burner
Burner Air Adjustment: The oil burner is preset for
operation at altitudes below 3000 feet. If operated at
higher altitudes, it may be necessary to adjust the air band
setting. Adjust the air band for a #1 or #2 smoke spot on
the Bacharach scale.
To adjust, start machine and turn burner ON (refer to
Operation for details). Loosen two locking screws found
in the air shutter openings (refer to figure below) 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 flue 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
assembly view. It is recommended that the oil burner be
serviced yearly or as needed. Contact your local service
center.
Water Supply
Connect water supply hose to water inlet. The water faucet
and supply hose must be capable of providing a minimum
of 4.0 gallons per minute (GPM).

cally grounded. If it should malfunction or break down,
grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This product
is equipped with a cord having an equipment ground-
ing conductor and a grounding plug. The plug must be
plugged into an appropriate outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
DANGER: Improper connection of the equipment
grounding conductor can result in a risk of electro-
cution. Check with a qualified electrician or service
personnel if you are in doubt as to whether the
outlet is properly grounded.
DANGER: Do not modify the plug provided with the
product - if it will not fit the outlet, have a proper outlet
installed by a qualified electrician. DO NOT use any
