Installation Instructions; Venting; Water And Fuel Supply - Hotsy 1424SS Operator's Manual

Getting Started
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life and lower maintenance cost.
The pressure washer should be run on a level surface and
in a protected area where it is not readily influenced by out-
side sources such as strong winds, freezing temperatures,
rain, etc. The pressure washer should be located to assure
easy access for filling of fluids, adjustments and mainte-
nance. Normal precautions should be taken by the operator
to prevent moisture from reaching the pressure washer.
It is recommended that a partition be made between the
wash area and the pressure washer to prevent direct spray
from the wand coming in contact with the pressure washer.
Moisture reaching the equipment will reduce the pressure
washer's service life. All installations should comply with
the local codes covering such installations.

Venting

WARNING - RISK OF EXPLOSION: Do not spray flam-
mable liquids or operate machine in areas where
flammable vapors are present. Operate only where
open flame or torch is permitted.
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: Some gases are heavier than air and will
spill out on the floor in the 2 to 3 minutes required for
the safety pilot valve to close off gas supply. There-
fore, always provide adequate space and ventilation
around these units.
IMPORTANT: A draft diverter shall be installed.

IMPORTANT: All venting must be in accordance with
applicable federal and state laws, and local ordi-
nances. Consult local heating contractors.
IMPORTANT: Not suitable for connection to Type
B gas vent if the stack temperature exceeds 243°C
(470°).
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 into a concealed space in 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 in-
sufficient 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 nec-
essary 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. This gas
fired pressure washer must have a draft diverter installed
in the flue. A draft diverter will permit proper upward flow
of exhaust flue gases.
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
poor burner conditions. If this machine is going to be in-
stalled to a 90° or extended exhaust vent run length which
may restrict air flow it is recommended that a contractor
install a power vent. When a contractor has found it impos-
sible to vent through the ceiling then power venting can
be calculated to help eliminate exhaust restriction on this
natural draft machine. This draft inducer (power vent) must
be installed by a licensed contractor who can calculate
size, operation connections and associated dampeners.
Hotsy is not a licensed contractor and as such we are
unable to make recommendations for suitable make and
model of power vents.
It is important that the licensed contractor consult local
building codes. Hotsy can only make recommendations
and the selection of the venting must take into account
the type of roof or wall material it contacts which could
change the vent requirement for compliance with local
building codes
Water Supply
Connect water supply hose to water inlet. The water faucet
and supply hose must be capable of providing a minimum
of 6.0 gallons per minute (GPM).
Fuel Supply
CAUTION: Have a qualified gas serviceman install
and service your equipment.
WARNING: Gas line supply pressure must not exceed
14 water column inches (.50 PSI).
IMPORTANT: Gas line must be provided with a shut
off valve.
IMPORTANT: The gas supply must be able to supply
a minimum of 525,000 BTU/HR at the machines rated
manifold pressure.
Consult building codes for installation requirements.
For proper and safe machine operation, we recommend
that a licensed contractor be consulted for machine
installation.
Natural Gas Fuel
Have a qualified gas serviceman install the natural gas
fuel supply line to the machine.
