GENERAL SAFETY INFORMATION
EXTERNAL DAMAGE
Do not operate the water heater until it has been fully checked
out by a qualified technician, if the water heater:
• Has been exposed to fire or damage.
• Displays evidence of sooting.
• Produces steam or unusually hot water.
If the water heater has been flooded it must be replaced.
CHEMICAL VAPOR CORROSION
WARNING
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. (Reference is made to the limited warranty for
complete terms and conditions).
IMPROPER COMBUSTION
WARNING
ATTIC AND/OR EXHAUST FANS OPERATING ON THE
PREMISES WITH A W A TER HEATER CAN RESUL T 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 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.
then call your gas supplier or service agent. Keep area clear
until a service call has been made.
At times you may not be able to smell an LP gas leak. One cause
is odor fade, which is a loss of the chemical odorant that gives LP
gas its distinctive smell. Another cause can be your physical
condition, such as having a cold or a diminishing sense of smell
with age. For these reasons, the use of a propane gas detector
is recommended.
IF YOU EXPERIENCE AN OUT-OF-GAS SITUATION, DO NOT
TRY TO RELIGHT APPLIANCE YOURSELF. Ask your LP delivery
person to relight pilots for you. Only trained LP professionals
should conduct the required safety checks in accordance with
industry standards.
EXTENDED NON-USE PERIODS
WARNING
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).
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.
SMOKING OR OPEN FLAME NEAR THE FAUCET A T THE TIME

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 heaters.
Your State water heater meets and exceeds the National
Appliance Energy Conservation Act standards with respect to
insulation and standby loss requirements, making an insulation
blanket unnecessary.
WARNING
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions (See Figure 1 for identification
of components mentioned below). Failure to follow these
instructions can restrict the air flow required for proper combustion,
potentially resulting in fire, asphyxiation, serious personal injury
or death.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND
VENTILATING AIR. ADEQUA TE AIR FOR COMBUSTION AND
VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.
LIQUID PETROLEUM MODELS
WARNING
Water heaters for propane or liquefied petroleum gas (LPG) are
different from natural gas models. A natural gas heater will not
function safely on LP gas and no attempt should be made to
convert a heater from natural gas to LP gas.
LP gas must be used with great caution. It is highly explosive
and heavier than air. It collects first in the low areas making its
odor difficult to detect at nose level. If LP gas is present or even
suspected, do not attempt to find the cause yourself. Go to a
neighbor's house, leaving your doors open to ventilate the house,
Do not cover the outer door, thermostat or temperature &
•
pressure relief valve.
•
Do not allow insulation to come within 2 inches of dilution air
inlet on the blower to prevent blockage of the dilution air.
•
Do not allow insulation to come within 2" of the floor to prevent
blockage of combustion air flow to the burner.
•
Do not cover the instruction manual. Keep it on the side of the
water heater or nearby for future reference.
•
Do obtain new warning and instruction labels from State
Water Heaters for placement on the blanket directly over the
existing labels.
•
Do inspect the insulation blanket frequently to make certain it
does not sag, thereby obstructing combustion air flow.

INSTALLATION
REQUIRED ABILITY
INSTALLATION OR SERVICE OF THIS WATER HEATER
REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED
TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR
SUPPL Y , VENTING AND GAS SUPPL Y ARE REQUIRED.
GENERAL
The installation must conform to these instructions and the local
code authority having jurisdiction. In the absence of local codes,
the installation must comply with the current editions of the
National Fuel Gas Code ANSI Z223.1/NFPA 54 and the National
Electrical Code, NFPA 70. The former is available from the
Canadian Standards Association, 8501 East Pleasant Valley
Road, Cleveland, OH 44131, and both documents are available
from the National Fire Protection Association, 1 Batterymarch
Park, Quincy, MA 02269.
GROUNDING
The water heater when installed must be grounded in
accordance with local codes, or in the absence of local codes:
In the United States
The National Electric Code, ANSI/NFPA 70.
AIR REQUIREMENTS
Dilution air temperature must be 100°F or less. In calculating the
free area of a vent opening, the blocking effect of screens, louvers
and grills should be considered. Screens shall not be of a mesh
smaller than 1/4 inch square. If the free area is not known, the
current edition of National Fuel Gas Code ANSI Z223.1/NFPA 54
recommends using figures of 20-25 percent free area for wood
louvers or 60-75 percent for metal grills or louvers.
UNCONFINED SPACE
In buildings of conventional frame, brick or stone construction,
unconfined spaces may provide adequate air for combustion,
ventilation, and dilution air for power venter.
If the unconfined space is within a building of tight construction
(as defined in the most recent revision of the National Fuel Gas
Code Handbook), air for combustion, ventilation, and venter
dilution must be obtained from outdoors. The installation
instructions for confined spaces must be followed.
HIGH ALTITUDE INSTALLATION
WARNING
STANDARD MODELS ARE FOR INSTALLATION UP TO 2,000
FEET (610m) ABOVE SEA LEVEL.
IF A STANDARD MODEL IS INSTALLED ABOVE 2,000 FEET
(610m), INPUT RATING SHOULD BE REDUCED AT A RATE 4
PERCENT FOR EACH 1,000 FEET (305m) ABOVE SEA LEVEL
WHICH REQUIRES REPLACEMENT OF THE BURNER ORIFICE
IN ACCORDANCE WITH THE NATIONAL FUEL GAS CODE
(ANSI Z223.1/NFP A 54).
FAILURE TO REPLACE THE ST ANDARD ORIFICE WITH A HIGH
ALTITUDE ORIFICE WHEN INSTALLED ABOVE 2,000 FEET
(610m) COULD RESULT IN IMPROPER AND INEFFICIENT
OPERATION OF THE W A TER HEA TER, PRODUCING CARBON
MONOXIDE GAS IN EXCESS OF SAFE LIMITS, WHICH COULD
RESULT IN SERIOUS INJURY OR DEATH. CONTACT YOUR
LOCAL GAS SUPPLIER FOR ANY SPECIFIC CHANGES WHICH
MAY BE REQUIRED IN YOUR AREA.
LOCATION OF HEATER
The heater is design certified by the Canadian Standards
Association for installation on combustible flooring in a closet
having minimum clearances from combustible material of: 0"
clearance from sides and rear, 5" from the front and 12" from the
top. (Standard clearance.) If clearances stated on the heater
differ from standard clearances, install water heater according
to clearances stated on heater.
Adequate clearance for servicing this appliance should be
considered before installation, such as changing the anodes, etc.
A minimum clearance of 5" must be allowed for access to
replaceable parts such as the thermostats, drain valve and relief
valve.
When installing the heater, consideration must be given to proper
location. Location selected should be as close to the wall as
practicable and as centralized with the water piping system as
possible.
Installation:
Do not install water heater
where
flammable products
will be stored or used
unless the main burner and
hot surface igniter are at
least 18” above the floor.
This will reduce, but not
eliminate, the risk of vapors
being ignited by the main
burner or hot surface
igniter.
CONFINED SPACE
When drawing combustion and dilution air from inside a
conventionally constructed building to a confined space, such a
space shall be provided with two permanent openings; ONE
WITHIN 12 INCHES OF THE ENCLOSURE TOP AND ONE IN
OR WITHIN 12 INCHES OF THE ENCLOSURE BOTTOM. Each
opening shall have a free area of one square inch per 1000 Btuh
of the total input of all appliances in the enclosure, but not less
than 100 square inches.
If the confined space is within a building of tight construction, air
for combustion, ventilation and power venter dilution must be
obtained from outdoors. When directly communicating with the
outdoors or communicating through vertical ducts, two
permanent openings, located in the above manner, shall be
provided. Each opening shall have a free area of not less than
one square inch per 4000 Btuh of the total input of all appliances
in the enclosure. If horizontal ducts are used, each opening
shall have a free area of not less than one square inch per 2000
Btuh of the total input of all appliances in the enclosure.

cannot be avoided, a suitable drain pan should be installed
under the heater, see fig. 1. The pan should have a minimum
length and width of at least 2 inches greater than the diameter of
the heater and should be piped to an adequate drain. Drain
pans suitable for these heaters are available from your dealer or
State Water Heaters, 500 Lindahl Parkway, Ashland City, TN
37015.
When such locations
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed. Water
heaters are sometimes installed in locations where leakage
may result in property damage, even with the use of a drain pan
piped to a drain. However, unanticip ated damage can be reduced
or prevented by a leak detector or water shut-off device used in
conjunction with a piped drain pan. These devices are available
from some plumbing supply wholesalers and retailers, and
detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or turn
off the incoming water to the water heater when leakage is
detected.
• Sensors mounted in the drain pan that turn off the water supply
to the entire home when water is detected in the drain pan.
• Water supply shut-off devices that activate based on the water
pressure differential between the cold water and hot water
pipes connected to the water heater.
• Devices that will turn off the gas supply to a gas water heater
while at the same time shutting off its water supply.

WATER (POTABLE) HEATING AND SPACE
HEATING
1. All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
2. Toxic chemicals, such as those used for boiler treatment,
shall NEVER be introduced into this system.
3. This unit may NEVER be connected to any existing heating
system or component(s) previously used with a non-potable
water heating appliance.
4. 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 2 for suggested piping arrangement.
FIGURE 2
CLOSED WATER SYSTEM
A closed system will exist if a back-flow preventer (check valve),
or similar device is installed in the cold water line between the
water heater and the street main (or well). Excessive pressure
may develop due to the thermal expansion of heated water
causing premature tank failure or intermittent relief valve
operation. This type of failure is not covered by the limited
warranty. An expansion tank may be necessary in the cold water
supply to alleviate this situation, see fig. 1. Contact the local
plumbing authority.
If the temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion
in a closed water supply system. Contact the water supplier or
local plumbing inspector on how to correct the situation.

IMPORT ANT
The vent system must terminate so that proper clearances are
maintained as cited in local codes or the current edition of the
National Fuel Gas Code, ANSI Z223.1/NFPA 54, 7.3.4e and 7.8a,b,
as follows:
1. The exit terminals of a mechanical vent system shall be not
less than 7 feet above grade when located adjacent to public
walkways. (Figure. 3)
2. A venting system shall terminate at least 3 feet above any
forced air inlet located within 10 feet. (Figure 3)
3. The venting system shall terminate at least 4 feet below, 4
feet horizontally from or, 1 foot above any door, window or
gravity air inlet into any building.
The manufacturer also recommends that the vent termination
should not be installed closer than 3 feet from an inside
corner of an L shaped structure and not be less than 1 foot
above grade.

4. In cold climates, it is recommended that vent termination not
be mounted directly above or within 3 feet horizontally from an
oil tank vent or gas meter to avoid potential freeze-up from
condensation.
Plan the vent system layout so that proper clearances are
maintained from plumbing and wiring.
Vent pipes serving power vented appliances are classified by
building codes as “vent connectors”. Required clearances from
combustible materials must be provided in accordance with
information in this manual under LOCATION OF HEATER and
VENT TERMINAL INSTALLATIONS, and with the National Fuel
Gas Code and local codes.
IMPORT ANT
Plan the layout of the vent system from the vent termination to the
appliance considering all of the 90 degree and 45 degree elbows
plus the number of feet of pipe that would be needed to install
the total vent system. Make sure to include the 90 degree elbow
if required at the blower. Review the tables on page 9 to make
sure that the vent system is within the allowed vent configuration.
Multiple fittings, 90 or 45 degree, installed in close proximity to
each other could result in intermittent lockouts or prevent the
unit from firing. Plan the layout to locate the fittings as far apart
as possible.
CAUTION
Termination of the vent system with a device other than the
supplied type vent terminal could effect system performance
and result in a safety hazard. The 2 inch vent terminal is a tee
and the 3 inch vent terminal is a 45 degree elbow. Both vent
terminals have protective screens.
WARNING
NEVER OPERATE THE HEATER UNLESS IT IS VENTED TO
THE OUTDOORS AND HAS ADEQUA TE AIR SUPPLY TO A VOID
RISKS OF IMPROPER OPERATION, FIRE, EXPLOSION OR
ASPHYXIATION.
Make sure the flue baffle and flue restrictor ring are properly
aligned and inserted on top of the flue. This can be checked
through the dilution air inlet of the blower.
VENT PIPE TERMINATION
NOTE: Before installing power venter determine place of vent
pipe termination. See figure 3 on page 7.
VENT TERMINAL INSTALLATION
1. After the point of termination has been determined, use the
cover plate as a template to mark the hole for the vent pipe to
insert through the wall.
AND PIPING INSIDE OF WALL.
2. If the Vent Terminal is being installed on the outside of a
finished wall, it may be easier to mark both the inside and
outside wall. Align the holes by drilling a hole through the
center of the template from the inside through to the outside.
The template can now be positioned on the outside wall using
the drilled hole as a centering point for the template.
