State Industries Premier Power Vent DV Series GP6 50 HTPDT 121 Series - Manual (Page 14)

14
This water heater shall not be connected to any heating systems or
component(s) used with a non-potable water heating appliance.
All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
Toxic chemicals, such as those used for boiler treatment shall not
be introduced into this system.
When the system requires water for space heating at temperatures
higher than required for domestic water purposes, a tempering
valve must be installed. Please refer to Figure 8 for suggested
piping arrangement.
power supplY
The water heaters covered in this manual require a 120 VAC,
1Ø (single phase), 60Hz, 15 amp power supply and must also
be electrically grounded in accordance with local codes or, in the
absence of local codes, with the National Electrical Code, ANSI/
NFPA 70.
power fluctuatIons and electrIcal noIse
The water heater’s control system requires a source of stable
clean electricity for proper operation. Connecting the water heater
to a branch circuit that is subject to fluctuations in voltage level or
electrical line noise such as EMI (electro magnetic interference)
or RFI (radio frequency interference) may cause erratic control
system operation and malfunction.
A high quality power supply filter/suppressor such as the Kleen Line
model SELF/T-10 Series SC-L or equivalent must be installed if the
above conditions exist. Call the technical support phone number
listed on the back cover of this manual for more information.
note: Malfunctions caused by the power supply and the costs
to install power supply filters are not covered under the limited
warranty.
dedIcated power wIrInG and breaKers
Dedicated power supply wires, ground wiring and dedicated
circuit breakers often prevent electrical line noise and should be
considered when installing the water heater.
polarItY sensItIve
The control system on the water heaters covered in this manual is
polarity sensitive; electronic flame sensing requires correct polarity.
The control system is programmed to monitor the incoming power
supply. If the Hot and Neutral wires in the 120 VAC power supply
are reversed, the control system will declare a Fault condition and
lock out, heating operation will be disabled until the power supply is
correctly wired. The control system will display the “AC Reversed”
Fault message on the LCD.
cheMIcal vapor corrosIon
CORROSION OF THE FLUEWAYS AND vENT SYSTEM MAY
OCCUR IF AIR FOR COMBUSTION CONTAINS CERTAIN
CHEMICAL vAPORS. SUCH CORROSION MAY RESULT IN
FAILURE AND RISk OF ASPHYXIATION.
Spray can propellants, cleaning solvents, refrigerator and air
conditioning refrigerants, swimming pool chemicals, calcium
and sodium chloride (water softener salt), waxes, and process
chemicals are typical compounds which are potentially
corrosive.
Do not store products of this sort near the heater. Also, air which is
brought in contact with the heater should not contain any of these
chemicals. If necessary, uncontaminated air should be obtained
from remote or outside sources. The limited warranty is voided
when failure of water heater is due to a corrosive atmosphere. (See
limited warranty for complete terms and conditions).
water pIpInG
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated
to a temperature which will satisfy space heating, clothes
washing, dish washing, cleaning and other sanitizing needs can
scald and permanently injure you upon contact. Some people
are more likely to be permanently injured by hot water than
others. These include the elderly, children, the physically or
developmentally disabled. If anyone using hot water fits into one
of these groups or if there is a local code or state law requiring
a certain temperature water at the hot water tap, then you must
take special precautions. In addition to using the lowest possible
temperature setting that satisfies your hot water needs, a means
such as a *mixing valve, should be used at the hot water taps
used by these people or at the water heater, see Figure 6. Valves
for reducing point of use temperature by mixing cold and hot
water are also available:
Consult a Qualified Installer or Service Agency. Follow
manufacturer’s instructions for installation of the valves.
Before changing the factory setting on the thermostat, read the
“Temperature Regulation” section in this manual.
