Installation Instructions - Hotsy 800 Series 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.
Burner Air Adjustment:
The oil burner on this machine is preset for opera-
tion at altitudes below 1000 feet. If operated at higher
altitudes, it may be necessary to adjust the air band
setting. Adjust air band for a #1 or #2 smoke spot
on the Bacharach scale. If a smoky or eye-burning
exhaust is being emitted from the stack, two things
should be checked. First, check the fuel to be certain
that kerosene or No.1 home heating fuel is being used.
Next, check the air adjustment on the burner. An oily,
smoky fire indicates a lack of air and the air band
should be moved to allow the air to flow through the
burner. Sharp eye-burning fumes indicate too much air
flowing through the combustion chamber. The air band
should be readjusted to allow less air to flow through
the burner.
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.

band until white smoke just starts to appear. Turn air
band halfway back to the previously noted position.
Tighten locking screws.
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) and a maximum pres-
sure of 65 psi.

WARNING: Make sure all switches and controls are in
the OFF position prior to connecting electrical supply.
WARNING: DO NOT stand in water while connecting
and disconnecting electrical supply.
WARNING: Always disconnect power before servicing
your pressure washer.
IMPORTANT: Consult local building codes for exact
electrical requirements. Licensed contractors may
be required.
IMPORTANT: This machine must be electrically
grounded. LA MACHINE DOIT ÊTRE MISE À LA TERRE.
Grounding Instructions: This product must be electri-
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.
