Operations

Improved Regulation:

The second stage regulator

receives a relatively uniform pressure from the first
stage regulator. This helps the second stage regulator
to maintain appliance pressure at a nearly constant 11"
W.C.

Filling the LP-Gas Container

Only qualified persons should fill your LP-gas
containers.

CAUTION: Overfilling is hazardous!

ATTENTION: Le remplissage excessif est
dangereux.

DO NOT allow your LP-gas container to be overfilled.
Stop filling when liquid appears at the fixed level gauge.
Bleed off excess propane in a safe area. Most LP-gas
containers are equipped with a fixed liquid level gauge
which contacts the liquid level at 80% of container
capacity, allowing 20% for expansion. LP-gas
containers not equipped with a fixed liquid level gauge
can only be filled by weight.

In cold climates, in order to keep vaporization of LP-gas
at the highest level, keep the fuel levels above 50%.

Propane Tank Disposal

Propane tanks present a real danger in the waste
stream, so it is essential to properly dispose of old
tanks so they do not injure you or sanitation workers.
The best way to dispose of unused propane tanks is by
calling a propane company to pick it up. Propane tanks
are not picked up by garbage collectors, and improper

disposal is illegal in some areas. If a propane tank is
unfit for service, one should contact a propane
company.

Venting

DANGER: DO NOT run machine indoors or in an
enclosed area without proper ventilation, as exhaust
fumes may be hazardous to your health.

DANGER: NE PAS faire fonctionner la machine à
l'intérieur ou dans un endroit fermé sans une
ventilation appropriée, car les gaz d'échappement
pourraient comporter des dangers pour la santé.

DANGER: DO NOT operate machine in areas where
flammable vapors (gasoline, solvents, etc.) may be
present, as this machine may ignite the vapors.

DANGER: NE PAS utiliser la machine dans des
endroits où des vapeurs inflammables (essence,
solvants, etc.) pourraient être présentes, car cette
machine pourrait enflammer les vapeurs

CAUTION: All venting must be in accordance with
applicable federal and state laws, and local ordi-
nances. This machine is not to be connected to a type
B gas vent. Consult local heating contractors.

ATTENTION: Toute la ventilation doit être conforme
aux lois fédérales et de l'État ou de la province, et aux
réglementations locales applicables. Cette machine
ne doit pas être raccordée à un évent de gaz de type
B. Consulter les entrepreneurs de chauffage locaux.

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 the machine 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 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.

Hotsy natural and LP gas series pressure washers that
incorporate a natural draft burner assembly designed to
heat water that comes from the pressure washer pump
require a draft diverter and vent pipe for exhausting to the
outside. This operator's manual indicates this machine is
to be vented through the ceiling using straight pipe or 45°
elbows. It also discourages the use of any 90° venting
elbows which restrict air flow through the burner causing
