OPERATION OF THESE FANS CAN PRODUCE A NEGATIVE
DRAFT IN THE AREA OF THE WATER HEATER PREVENTING
THE PRODUCTS OF COMBUSTION FROM EXHAUSTING
THROUGH THE CHIMNEY OR VENT PIPE.
The venting of the water heater should be inspected by a qualified
service technician at the time of installation and periodically
thereafter to ensure a down-draft condition does not exist.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND
VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION AND
VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.
EXTENDED NON-USE PERIODS
HYDROGEN GAS CAN BE PRODUCED IN A HOT WATER SYSTEM
SERVED BY THIS HEATER THAT HAS NOT BEEN USED FOR A
LONG PERIOD OF TIME (GENERALLY TWO WEEKS OR MORE).
HYDROGEN GAS IS EXTREMELY FLAMMABLE. To reduce the
risk of injury under these conditions, it is recommended that the
hot water faucet be opened for several minutes at the kitchen
sink before using any electrical appliance connected to the hot
water system. If hydrogen is present, there will probably be an
unusual sound such as air escaping through the pipe as the
water begins to flow. THERE SHOULD BE NO SMOKING OR
OPEN FLAME NEAR THE FAUCET AT THE TIME IT IS OPEN.
INSULATION BLANKETS
Insulation blankets available to the general public for external
use on gas water heaters are not approved for use on your
State water heater. The purpose of an insulation blanket is to
reduce the standby heat loss encountered with storage tank
water heaters. Your State water heater meets or exceeds
the ASHRAE/IES 90.1-1999 standards with respect to
insulation and standby loss requirement making an insulation
blanket unnecessary.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions. Failure to follow these
instructions can result in fire, asphyxiation, serious personal
injury or death.
• Do not apply insulation to the top of the water heater, as
this will interfere with safe operation of drafthood.
• Do not cover the temperature & pressure relief valve.
• Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
• Do obtain new labels from State Water Heaters for
placement on the blanket directly over the existing labels.
HIGH ALTITUDE INSTALLATIONS
INSTALLATIONS ABOVE 2000 FEET (610 METERS) REQUIRE
REPLACEMENT OF THE BURNER ORIFICE IN ACCORDANCE
WITH SECTION 8.1.2 OF THE NATIONAL FUEL GAS CODE
(ANSI Z223.1). FAILURE TO REPLACE THE ORIFICE WILL RESULT
IN IMPROPER AND INEFFICIENT OPERATION OF THE APPLIANCE
RESULTING IN THE PRODUCTION OF INCREASED LEVELS OF
CARBON MONOXIDE GAS IN EXCESS OF SAFE LIMITS WHICH
COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
You should contact your gas supplier for any specific changes
which may be required in your area.
WARNING
WARNING
WARNING
As elevation above sea level is increased, there is less oxygen
per cubic foot of air. Therefore, the heater input rate should be
reduced at high altitudes for satisfactory operation with the
reduced oxygen supply. Failure to make this reduction would
result in an overfiring of the heater causing sooting, poor
combustion and/or unsatisfactory heater performance.
REQUIREMENTS
Ratings specified by manufacturers for most appliances apply
for elevations up to 2000 feet. For elevations above 2000 feet,
ratings must be reduced at the rate of 4% for each 1000 feet
above sea level.
For example, if a heater is rated at
120,000 Btuh at sea level, to rate the heater at 4000 feet, you
subtract 4 (once for each thousand feet) x.04 (4% input reduction)
x 120,000 Btuh (original rating) from the original rating. Therefore,
to calculate the input rating at 4,000 feet: 4 x .04 x 120,000 =19,200
Btuh, 120,000 - 19,200 = 100,800 Btuh. At 6000 feet the correct
input rating should be 91,200 Btuh.
The input reduction is primarily achieved by reducing the size of
the main burner orifices. To do this, the main burner orifices
require replacement with orifices sized for the particular
installation elevation. Correct orifice sizing and parts may be
obtained from State Water Heaters. When ordering, be sure to
state the model number and the altitude of the location where
the water heater is being installed.
Upon completion of derating of the heater, adjustment to the gas
pressure regulator may be required. See CHECKING THE
INPUT section in this manual for inlet and manifold pressure
requirements.
Also due to the input rating reduction required at high altitudes,
the output rating of the appliance is also reduced and should be
compensated for in the sizing of the equipment for application.
FEATURES
SELF-CLEANING HYDRO-CANNON
These units include a self-cleaning hydro-cannon installed in
the front water inlet. See figure 2. The hydro-cannon must be
oriented correctly for proper function. There is a marked range
on the pipe nipple portion of the hydro-cannon, that must be
aligned with the top of the inlet spud. A label above the jacket
hole has an arrow that will point to the marked portion of the
pipe nipple if the orientation is correct.
point within the marked range on the pipe nipple, adjust the pipe
nipple to correct. A pipe union is supplied with the hydro-cannon
to reduce the probability of misaligning the hydro-cannon
accidentally while tightening the connection to the inlet water
supply line. Improper orientation of the hydro-canon can cause
poor performance of the heater and can significantly reduce
outlet water temperatures during heavy draws.
NOTE: The inlet may have 1, 2 or 7 cross- tubes.
HIGH LIMIT SWITCH
The digital thermostat (Figure 3) contains the high limit (energy
cutoff) sensor. The high limit switch interrupts main burner gas
flow should the water temperature reach 203°F (195°C).
