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 no 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. (Refer to the limited warranty for complete terms
and conditions).
IMPROPER COMBUSTION
WARNING
ATTIC AND OR EXHAUST FANS OPERATING ON THE
PREMISES WITH A WATER HEATER CAN RESULT IN CARBON
MONOXIDE POISONING AND DEATH.
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 qualied
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
VENTILATION AIR, ADEQUATE AIR FOR COMBUSTION AND
VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.
EXTENDED NON-USE PERIODS
CATHODIC PROTECTION
CAUTION
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 a hot water faucet be opened for several
minutes 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 ow. There should be not smoking or open

INSULATION BLANKETS
WARNING
INSULATION BLANKET 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 HEATER. YOUR STATE WATER
HEATER MEETS OR EXCEEDS THE ASHRAE/IES 90.1B 2001
STANDARDS WITH RESPECT TO INSULATION AND STANDBY
LOSS REQUIREMENTS, MAKING AN INSULATION BLANKET
UNNECESSARY. THE USE OF INSULATION BLANKETS IN
CONJUNCTION WITH A STATE WATER HEATER WILL ALSO VOID
THE STATE WARRANTY FOR THE FOLLOWING REASONS:
1. INSULATION BLANKETS COVER IMPORTANT OPERATING
INSTRUCTIONS AND SAFETY LABELS.
2. INSULATION BLANKETS CAN RESTRICT THE AIR FLOW
NEEDED FOR PROPER OPERATION OF THE COMBUSTION
SYSTEM AND COULD RESULT IN FIRE, ASPHYXIATION,
SERIOUS PERSONAL INJURY OR DEATH.
WARNING
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT
IN SERIOUS PERSONAL INJURY OR DEATH.
HIGH ALTITUDE INSTALLATIONS
Your State water heater has been designed to operate at altitudes
below 2000 Ft. (609.6 m), for appliance installation locations with
elevations above 2000 Ft. (609.6 m), special considerations need
to be taken. Adjustments for high altitude can only be made by a
State authorized GPG/GPV Start-up Agent. To ensure your water
heater operates properly at high elevation, a State authorized
GPG/GPV Start-up Agent will readjust the air-intake damper setting
and the gas manifold pressure (if required).
NOTE: Some gas utility companies derate the heating value
of the supplied gas at high elevation. Your authorized start-up
agent must adjust for actual heating value of the gas at the
time of start up.
FEATURES
LOW EMISSION CONTROL
Your State water heater has been designed to comply with
standards established by California South Coast Air Quality
Management District (SCAQMD), the most stringent emissions
control agency in the nation. To ensure compliance with SCAQMD
Rule 1146.2, your heater is equipped with an internal recirculation
premix power burner, and must be started/adjusted by a
State Authorized GPG/GPV Start-Up Agent.
HIGH LIMIT SWITCH (E.C.O.)
The dual bulb controller also contains the high limit (energy cutoff)
sensor. The high limit switch interrupts main burner gas ow
should the water temperature reach 205°F (96°C).
In the event of high limit switch operation, the appliance cannot be
restarted unless the water temperature is reduced by 20°F (11°C)
approx. and the high limit reset button on front of limit control is
depressed, see Figure 1.
