FOREWORD

These designs comply with ANSI Z21.10.3/CSA 4.3 as an automatic

circulating or automatic storage tank type water heater.

Heaters having an input of 305,000 (89 kWh), 365,000 (107 kWh),

399,000 (117 kWh) and 500,000 (147 kWh) Btuh with a recovery

rating of 277.3 gph (1049 Lph) or more also comply with ANSI

Z21.10.3 as an automatic instantaneous type heater.

Detailed installation diagrams are found in this manual. These

diagrams will serve to provide the installer with a reference for the

materials and methods of piping necessary. It is highly essential

that all water, gas piping and wiring be installed as shown on the

diagrams.

Particular attention should be given to the installation of

thermometers at the locations indicated on the diagrams as

these are necessary for checking the proper functioning of

the heater.

This model water heater is designed and manufactured in both

natural gas and propane versions. MAKE SURE the gas on which

the heater will operate is the same as that specied on the heater

model and rating plate.

These heaters may be installed on combustible oors. Refer

to LOCATING THE HEATER and INSTALLATION ON

COMBUSTIBLE FLOORING sections for details.

In addition to these instructions, the equipment shall be installed in

accordance with those installation regulations in force in the local

area where the installation is to be made. These shall be carefully

followed in all cases. Authorities having jurisdiction should be

consulted before installations are made.

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 latest editions of the National

Fuel Gas Code, ANSI Z223.1/NFPA 54 and the National Electrical

Code, NFPA 70, CAN/CSA B149.1, and CSA 2 C22.1. 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.

GENERAL SAFETY

INFORMATION

PRECAUTIONS

DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN

UNDER WATER. Immediately call a qualied service technician

to inspect the appliance and to replace any part of the control

system and any gas control which has been under water.

IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT

OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE

BEEN MADE BY A QUALIFIED SERVICEMAN.

1. EXTERNAL FIRE.

2. DAMAGE.

3. FIRING WITHOUT WATER.

4. SOOTING

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 and typical compounds which are potentially corrosive.

Do not store products of this sort near the heater. Also, air which

is brought in contact with a 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. (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

VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION AND

VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.

LIQUID PETROLEUM MODELS

Water heaters for propane or liqueed 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 rst in the low areas making its

odor difcult to detect at nose level. If LP gas is present or even

suspected, do not attempt to nd the cause yourself. Go to a

neighbor’s house, leaving your doors open to ventilate the house,

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 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 APPLIANCES 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). 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 ow. 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.

WARNING

Should you choose to apply an insulation blanket to this heater,

you should follow these instructions. Failure to follow these

instructions can result in re, 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 gas valve or 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 not allow insulation to come within 2” (5cm) of the burners,

to prevent blockage of combustion air ow to the burners.

• Do not allow insulation to come within 9” (23cm) of oor, (within

2” (5cm) of bottom cover) to prevent blockage of combustion

air ow to the burners.

• Do inspect the insulation blanket frequently to make sure it

does not sag, thereby obstructing combustion air ow.

• Do obtain new labels from State for placement on the blanket

directly over the existing labels.

HIGH ALTITUDE INSTALLATIONS

WARNING

INSTALLATIONS ABOVE 2000 FEET (610 METERS)

REQUIRE REPLACEMENT OF THE BURNER ORIFICES IN

ACCORDANCE WITH THE NATIONAL FUEL GAS CODE

(ANSI Z223.1). FAILURE TO REPLACE THE ORIFICES 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 specic changes

which may be required in your area.

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 overring of the heater

causing sooting, poor combustion and/or unsatisfactory

heater performance.

Ratings specied by manufacturers for most appliances

apply for elevations up to 2000 feet (610m). For elevations

above 2000 feet (610), ratings must be reduced at the rate of

4% for each 1000 feet (305m) above sea level. For example,

if a heater is rated at 120,000 Btuh (35 kWh) at sea level,

to rate the heater at 4000 feet (1219m), you subtract 4

(once for each thousand feet) x .04 (4% input reduction) x

120,000 (original rating) from the original rating. Therefore,

to calculate the input rating at 4,000 feet (121.9m): 4 x

.04 x 120,000 =19,200 Btuh (5.6 kWh), 120,000 (35 kWh)

- 19,200 (5.6 kWh) = 100,800 Btuh (29.4 kWh). At 6000

feet (1829m) the correct input rating should be 91,200 Btuh

(26.7 kWh).

The input reduction is primarily achieved by reducing the size

of the main burner orices. To do this, the main burner orices

require replacement with orices sized for the particular installation

elevation. Correct orice 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 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.

If the arrow does not 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 tube may have 1, 3 or 7 cross-tubes.

FIGURE 2

For proper function, the hydro cannon must be oriented correctly.

There is a marked range on the pipe nipple that must be aligned

with the top of the inlet spud (check for label on the appliance) to

assure proper orientation. Please check to conrm that the marked

range is in alignment with the top of the spud. A pipe union is

supplied with the hydro cannon to help eliminate the possibility of

changing the orientation by accidentally over-tightening the inlet

supply line. Improper orientation of the hydro cannon may cause

temperature build-up issues or spells of colder than usual water

temperatures.

HIGH LIMIT SWITCH

The digital thermostat (Fig. 3) contains the high limit (energy cutoff)

sensor. The high limit switch interrupts main burner gas ow should

the water temperature reach 203°F (95°C).

In the event of high limit switch operation, the appliance cannot be

restarted unless the water temperature is reduced to approximately

120°F (49°C). The high limit reset button on the front of the control

then needs to be depressed.

Continued manual resetting of high limit control, preceded by

higher than usual water temperature is evidence of high limit

switch operation. The following is a possible reason for high limit

switch operation:

• A malfunction in the thermostatic controls would allow the gas

valve to remain open causing water temperature to exceed the

thermostat setting. The water temperature would continue to

rise until high limit switch operation.

Contact your dealer or service agent if continued high limit switch

operation occurs.

DIGITAL THERMOSTAT

FIGURE 3

ELECTRONIC IGNITION CONTROL

Each heater is equipped with a Honeywell ignition module. The

solid state ignition control, g. 4, ignites the pilot burner gas by

creating a spark at the pilot assembly. Pilot gas is ignited and

burns during each running cycle. The main burner and pilot gases

are cut off during the OFF cycle. Pilot gas ignition is proven by the

pilot sensor. Main burner ignition will not occur if the pilot sensor

does not rst sense pilot ignition.

HONEYWELL IGNITION MODULE

S8600M Continuous Re-Try

FIGURE 4

AUTOMATIC FLUE DAMPER DEVICE

All units are equipped with an automatic ue damper that reduces

heat loss during the OFF cycles. The automatic ue damper

drive assembly is a eld replaceable part and may be obtained

by contacting State Water Heaters.

Each automatic ue damper drive assembly is equipped with a

“Service Switch”, as shown in gure 5.

FIGURE 5

The “Service Switch” has 2 positions: AUTOMATIC OPERATION

and HOLD OPEN DAMPER. For normal operation the switch

should be in the AUTOMATIC OPERATION position.

If there is a problem with the damper the “Service Switch” can be

placed in the HOLD OPEN DAMPER position. When the switch

is placed in the HOLD OPEN DAMPER position the damper disc

will rotate to the open position and the heater may be used until

vent assembly is repaired or replaced. DO NOT turn the damper

disc manually; damage will occur to the drive assembly if operated

manually. Refer to TESTING DAMPER OPERATION section of

this manual for additional information.

CIRCULATING PUMP

A circulating pump is used when a system requires a

circulating loop or there is a storage tank used in conjunction

with the heater. Refer to the piping diagrams in this manual

for electrical hookup information and install in accordance

with the current edition of the National Electrical Code ANSI/

NFPA No. 70.

Only all bronze circulators should be used with commercial

water heaters.

Although circulators are oiled and operated by the manufacturer

some circulators must be oiled again before operating. Please

refer to manufacturer’s instructions.

DISHWASHING MACHINE REQUIREMENT

These appliances meet the NSF Standard 5 for sanitary

installations when used with the following leg kits, Part No’s.

6570-0 and 6570-7.

All dishwashing machines meeting the National Sanitation

Foundation requirements are designed to operate with water

ow pressures between 15 and 25 psi (103 Kpa and 173

Kpa). Flow pressures above 25 psi (173 Kpa), or below

15 psi (103 Kpa), will result in improperly sanitized dishes.

Where pressures are high, a water pressure reducing or ow

regulating control valve should be used in 180°F (82°C) line to

the dishwashing machine, and should be adjusted to deliver

water between these limits.

The National Sanitation Foundation also recommends circulation

of 180°F (82°C) water. Where this is done, the circulation

should be very gentle so that it does not cause any unnecessary

turbulence inside the water heater. The circulation should be

just enough to provide 180°F (82°C) water at the point of take-off

to the dishwashing machine. Adjust ow by means of the plug

cock in the circulating line.

INSTALLATION INSTRUCTIONS

REQUIRED ABILITY

INSTALLATION OR SERVICE OF THIS WATER HEATER

REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED

TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR

SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK

ARE REQUIRED.

FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT

IN SERIOUS PERSONAL INJURY OR DEATH.

UNCRATING

The heater is shipped with the ue damper already installed. The

wiring conduit runs from the thermostat to the damper drive cover.

Before turning unit on, check to make sure the wiring conduit is

securely plugged into damper drive.

LOCATING THE HEATER

When installing the heater, consideration must be given to

proper location. Location selected should be as close to the

stack or chimney as practicable, with adequate air supply and as

centralized with the piping system as possible.

WARNING

THERE IS A RISK IN USING FUEL BURNING APPLIANCES

SUCH AS GAS WATER HEATERS IN ROOMS, GARAGES OR

OTHER AREAS WHERE GASOLINE, OTHER FLAMMABLE

LIQUIDS OR ENGINE DRIVEN EQUIPMENT OR VEHICLES ARE

STORED, OPERATED OR REPAIRED. FLAMMABLE VAPORS

ARE HEAVY AND TRAVEL ALONG THE FLOOR AND MAY BE

IGNITED BY THE HEATER’S PILOT OR MAIN BURNER FLAMES

CAUSING FIRE OR EXPLOSION. SOME LOCAL CODES

PERMIT OPERATION OF GAS APPLIANCES IN SUCH AREAS

IF THEY ARE INSTALLED 18” (.50m) OR MORE ABOVE THE

FLOOR. THIS MAY REDUCE THE RISK IF LOCATION IN SUCH

AN AREA CANNOT BE AVOIDED.

DO NOT INSTALL THIS WATER HEATER DIRECTLY ON A

CARPETED FLOOR. A FIRE HAZARD MAY RESULT. Instead the

water heater must be placed on a metal or wood panel extending

beyond the full width and depth by at least 3 inches (7.6cm) in

any direction. If the heater is installed in a carpeted alcove, the

entire oor shall be covered by the panel. Also, see the DRAIN

REQUIREMENTS.

THE HEATER SHALL BE LOCATED OR PROTECTED SO IT

IS NOT SUBJECT TO PHYSICAL DAMAGE BY A MOVING

VEHICLE.

WARNING

FLAMMABLE ITEMS, PRESSURIZED CONTAINERS OR ANY

OTHER POTENTIAL FIRE HAZARDOUS ARTICLES MUST

NEVER BE PLACED ON OR ADJACENT TO THE HEATER.

OPEN CONTAINERS OR FLAMMABLE MATERIAL SHOULD

NOT BE STORED OR USED IN THE SAME ROOM WITH THE

HEATER.

THE HEATER MUST NOT BE LOCATED IN AN AREA WHERE

IT WILL BE SUBJECT TO FREEZING.

LOCATE IT NEAR A FLOOR DRAIN. THE HEATER SHOULD

BE LOCATED IN AN AREA WHERE LEAKAGE FROM THE

HEATER OR CONNECTIONS WILL NOT RESULT IN DAMAGE

TO THE ADJACENT AREA OR TO LOWER FLOORS OF THE

STRUCTURE.

WHEN SUCH LOCATIONS CANNOT BE AVOIDED, A SUITABLE

DRAIN PAN SHOULD BE INSTALLED UNDER THE HEATER.

Such pans should be fabricated with sides at least 2” (5cm) deep,

with length and width at least 2” (5cm) greater than the diameter

of the heater and must be piped to an adequate drain. The pan

must not restrict combustion air ow.

For appliance installation locations with elevations above 2000

feet (610m), refer to HIGH ALTITUDE INSTALLATIONS section

of this manual for input reduction procedure.

LEVELING

If the unit is not level, insert the bolts which were used in crating

into the legs to correct this condition.

In all installations the minimum combustible clearances from any

draft hood surface or vent piping shall be 6” (16cm). Vent piping

passing through a combustible wall or ceiling must be a continuous

run (no joints) and retain the 6” (16cm) clearance unless an

approved reducing thimble is used.

A service clearance of 24” (61cm) should be maintained from

serviceable parts, such as relief valves, ue bafes, ue damper

devices, thermostats, cleanout openings or drain valves.

HARD WATER

Where hard water conditions exist, water softening or the threshold

type of water treatment is recommended. This will protect the

dishwashers, coffee urns, water heaters, water piping and other

equipment.

See MAINTENANCE section for details of tank cleanout

procedure.

AIR REQUIREMENTS

REFER TO THE CURRENT EDITION OF THE “NATIONAL FUEL

GAS CODE” ANSI Z223.1/NFPA 54.

WARNING

KEEP APPLIANCEAREA CLEAR AND FREE OF COMBUSTIBLE

MATERIALS, GASOLINE AND OTHER FLAMMABLES, VAPORS

AND LIQUIDS.

DO NOT OBSTRUCT THE FLOW OF COMBUSTION OR

VENTILATING AIR.

WARNING

FOR SAFE OPERATION PROVIDE ADEQUATE AIR FOR

COMBUSTION AND VENTILATION. AN INSUFFICIENT SUPPLY

OF AIR WILL CAUSE RECIRCULATION OF COMBUSTION

PRODUCTS RESULTING IN AIR CONTAMINATION THAT

MAY BE HAZARDOUS TO LIFE. SUCH A CONDITION OFTEN

WILL RESULT IN A YELLOW, LUMINOUS BURNER FLAME,

CAUSING CARBONING OR SOOTING OF THE COMBUSTION

CHAMBER, BURNERS AND FLUE TUBES AND CREATES A

RISK OF ASPHYXIATION.

Where an exhaust fan is supplied in the same room with

a heater, sufcient openings for air must be provided in

the walls. UNDERSIZED OPENINGS WILL CAUSE AIR TO

BE DRAWN INTO THE ROOM THROUGH THE CHIMNEY,

CAUSING POOR COMBUSTION. SOOTING MAY RESULT IN

SERIOUS DAMAGE TO THE HEATER AND RISK OF FIRE OR

EXPLOSION.

UNCONFINED SPACE

In buildings of conventional frame, brick, or stone construction,

unconned spaces may provide adequate air for combustion,

ventilation and draft hood dilution.

If the unconned space is within a building of tight construction

(buildings using the following construction: weather stripping,

heavy insulation, caulking, vapor barrier, etc.), air for combustion,

ventilation and draft hood dilution must be obtained from outdoors.

The installation instructions for confined spaces in tightly

constructed buildings must be followed to ensure adequate air

supply.

CONFINED SPACE

When drawing combustion and dilution air from inside a

conventionally constructed building to a conned space, such a

space shall be provided with two permanent openings, ONE IN OR

WITHIN 12 INCHES (30.5cm) OF THE ENCLOSURE TOP AND

ONE IN OR WITHIN 12 INCHES (30.5cm) OF THE ENCLOSURE

BOTTOM. Each opening shall have a free area of at least one

square inch per 1000 Btuh (2,225mm2/kW) of the total input of all

appliances in the enclosure, but not less than 100 square inches

(645 square cm).

If the conned space is within a building of tight construction,

air for combustion, ventilation, and draft hood dilution must be

obtained from outdoors. When directly communicating with the

outdoors or communicating with the outdoors 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 (8,900mm2/kW) 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 (4,450mm2/kW) of the total input

of all appliances in the enclosure.

VENT REDUCER

The SBD 250, 251, and 275 models are shipped with an 8” to

6” diameter ue outlet adapter. Each adapter ts on top of the

installed ue damper. Use only vent reducers supplied with the

unit. The venting must comply with the NATIONAL FUEL GAS

CODE, ANSI Z223.1/NFPA 54.

FIGURE 7

FIGURE 6

VENTING

WARNING

THE INSTRUCTIONS IN THIS SECTION ON VENTING MUST

BE FOLLOWED TO AVOID CHOKED COMBUSTION OR RE-

CIRCULATION OF FLUE GASES. SUCH CONDITIONS CAUSE

SOOTING OR RISKS OF FIRE AND ASPHYXIATION.

Heater must be protected from freezing downdrafts.

Remove all soot or other obstructions from the chimney that will

retard a free draft.

Type B venting is recommended with these heaters. See table 3

TECHNICAL DATA VENTING.

This water heater must be vented in compliance with all local

codes, the current edition of the National Fuel Gas Code (ANSI-

Z223.1) and with the Category I Venting Tables.

If any parts of the vent system are exposed to ambient

temperatures below 35 degrees F (2 degrees C) they must be

insulated to prevent condensation.

• Do not connect the heater to a common vent or chimney with

solid fuel burning equipment. This practice is prohibited by

many local building codes as is the practice of venting gas

red equipment to the duct work of ventilation systems.

• Where a separate vent connection is not available and the

vent pipe from the heater must be connected to a common

vent with an oil burning furnace, the vent pipe should enter the

smaller common vent or chimney at a point above the large

vent pipe.

FIGURE 8

MULTIPLE HEATER MANIFOLD

Figure 9 and table 3 should be used for horizontally manifolding two

or more heaters. Also see MULTIPLE-UNIT INSTALLATIONS of

MECHANICAL VENTING section for induced draft applications.

FIGURE 9

WATER LINE CONNECTIONS

This manual provides detailed installation diagrams (see pages

16-22 of this manual) for typical methods of application for the

water heaters.

The water heater may be installed by itself, or with a separate

storage tank, on both single and two-temperature systems.

When used with a separate storage tank, the circulation may

be either by gravity or by means of a circulating pump. When a

circulating pump is used it is important to note that the ow rate

should be slow so that there will be a minimum of turbulence

inside the heater.

If a water heater is installed in a closed water system, contact

the water supplier or local plumbing inspector on how to control

this situation.

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 installation

diagrams on pages 16 through 22 in this manual for suggested

piping arrangements.

CAUTION

A closed system will exist if a check valve (without bypass),

pressure reducing valve (without bypass), or a water meter (without

bypass) is installed in the cold water line between the water heater

and street main (or well).

Excessive pressure may develop in such closed systems, causing

premature tank failure or intermittent relief valve operation. This

is not a warranty failure. An expansion tank or a similar device

may be required in the inlet supply line between the appliance

and the meter or valve to compensate for the thermal expansion

of the water.

SYSTEM CONNECTIONS

The system installation must conform to these instructions and to

the local code authority having jurisdiction. Good practice requires

that all heavy piping be supported.

THERMOMETERS (Not Supplied)

Thermometers should be obtained and eld installed as shown in

the installation diagrams.

Thermometers are installed in the system as a means of detecting

the temperature of the outlet water supply.

RELIEF VALVE

This water heater is equipped with a combination temperature-

pressure relief valve that complies with the standard for relief

valves and automatic gas shutoff devices for hot water supply

system, ANSI Z21.22. FOR SAFE OPERATION OF THE WATER

HEATER, THE RELIEF VALVE(S) MUST NOT BE REMOVED

OR PLUGGED.
