Operations
Installation
Place machine in a convenient location providing
ample support, drainage and room for maintenance.
Location
The location should protect the machine from
damaging environmental conditions, such as wind, rain
and freezing.
1. The cleaner should be run on a level surface where
it is not readily influenced by outside sources such
as strong winds, freezing temperatures, rain, etc.
The machine should be located considering acces -
sibility for the replacing of components, adjust -
ments and maintenance. Normal precautions
should be taken by the operator to prevent excess
moisture from reaching this power machine or
electrical controls.
2. It is recommended that a partition be made
between the wash area and the NG to prevent
direct spray from the spray gun from coming in
contact with the NG. Excess moisture reaching the
NG’s gas valve will reduce the life of the gas valve
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 this
machine 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 machine.
4. Do not locate near any combustible material. Keep
all flammable material at least 20 feet away. Allow
enough space for servicing. Local code will require
certain distances from floor and walls. (Two feet
away should be adequate).
WARNING: Avoid small areas or near exhaust fans.
AVERTISSEMENT: Éviter les petites superficies ou
les surfaces à proximité des ventilateurs
d'extraction.
Gas Codes
Confer with local gas company and with proper
municipal officials regarding any specific code or regu -
lations 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 for high altitude adjustments.
In Canada, certification for installation at altitudes over
4500 feet above sea level is the jurisdiction 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 specifi -
cation plate for the correct pressure setting. Follow the
installation and adjustment instructions 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
Burning Appliances”.
Electrical
The heating module runs on a self-generating millivolt
thermopile and does not require electrical AC power.
The pressure washer you attach to this heating module
must be electrically grounded in accordance to local
codes. Check for proper power supply using a volt
meter; check the serial plate and specifications for the
correct requirements.
Gas Piping
All piping must comply with local codes and ordinances
of the National Fuel Gas Code: A sediment trap or drip
leg must be installed in the supply line to the burner.
A union shall be installed in the gas line adjacent to and
upstream from the control manifold and downstream
from the manual main shut-off valve.
