WARNING: Moving this machine on an incline may
cause instability and could result in the machine
tipping over. Equipment damage or bodily harm
could occur.
Place machine in a convenient location providing ample
support, drainage and room for maintenance.
These machines are intended for indoor use. ma-
chine must be stored indoors when not in use.
location:
The location should protect the machine from damag-
ing environmental conditions, such as wind, rain and
freezing.
1. The machine should be run on a level surface
where it is not readily influenced by outside sources
such as strong winds, freezing temperatures, rain,
etc. Consider accessibility for the replacing of LP
tanks, refilling of detergents, adjustments and
maintenance when selecting a location. Normal
precautions should be taken by the operator to
prevent excess moisture from reaching electrical
components.
2. It is recommended that a partition be made be-
tween the wash area and the machine to prevent
direct spray from the spray gun to come in contact
with machine. Excess moisture reaching the elec-
trical controls will reduce the machine life and may
cause electrical shorts.
3. During installation, beware of poorly ventilated
locations or areas where exhaust fans may cause
an insufficient supply of oxygen. Sufficient combus-
tion 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 in a poorly
ventilated area, outside fresh air may have to be
piped to the burner and a fan installed to bring air
into the room. Avoid small locations or areas near
exhaust fans.
gas Codes:
Confer with local gas company and with proper mu-
nicipal officials regarding any specific code or regula-
tions governing the installation. The installation must
conform to local codes.
The gas pressure coming out of the regulator and going
to the burner ring has been factory set for elevations of
0 to 2000 ft. Altitudes greater than 2000 ft will require
adjustments to the gas manifold pressures. Consult
your local service dealer/distributor for high altitude
adjustments. In Canada, certification for installation
at altitudes over 4500 feet above sea level is the juris-
diction of local authorities. You should not readjust the
burner ring gas pressure. If you replace your gas valve,
you will need to adjust the new valve. Refer to your
machine’s specification plate for the correct pressure
setting. Follow the installation and adjustment instruc-
tions provided with your replacement valve.
noTe: Air for combustion and ventilation along with
exhaust flue sizing must conform to methods outlined
in current American Standard (ANSI-Z223.1) National
Fuel Gas Code or National Standard of Canada CSA-
149.1 and CSA-149.2 “Installation Code for Gas Burn-
ing Appliances”.
electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter. The VHP2-
15021D requires a 20 amp receptacle to comply with
UL 1776 certification standards.
venting:
Regulations or ventilation concerns may call for a
chimney or furnace pipe.
When venting, if the machine is to be in an enclosed
area with a chimney on it, be sure the chimney is the
same size as the stack on the machine. Poor draft
will cause machine to soot and not operate efficiently.
When placing for installation, keep in mind that the
pressure washer should be positioned in such a man-
ner that the stack will be as straight as possible and
protrude through the roof of the building at a proper
location and at sufficient height to eliminate downdraft.
The chimney of gas fired machines should be installed
with a down draft diverter.
Draft Diverter:
A draft diverter should be installed above the heating
coil. The diverter serves to sever the chimney effect
created in all sections of furnace pipe positioned below
to enhance the draft through the burner. It also helps
prevent freezing of the coil due to wind chill factors.
noTe: the draft diverter is not standard on VHP ma-
chines.
When the pressure washer is installed in a tightly closed
room without ventilation openings to the outdoors or
other rooms, provisions shall be made for supplying
air for combustion through special openings, one near
the floor line and the other near the ceiling, each to be
sized on the basis of one square inch or more of free
area for each 1,000 BTU input per hour.
