Installation (Locating The Water Heater) continued

-

Water heater corrosion and component failure can be caused by the heating
and breakdown of airborne chemical vapors. Examples of some typical
compounds that are potentially corrosive are: spray can propellants, cleani ng
solvents, refrigerator and air conditioning refrigerants, swimming pool
chemi cals, calcium and sodium chloride, waxes and process chemicals.
These materials are corrosi ve at very low concentration lev els wi th little or no
odor to reveal their pr esence.

NOTE: DAMAGE T O THE WATER HEATER
CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED
BY THE WARRANTY. DO NOT OPERATE THE WATER HEATER IF
EXPOSURE HAS OR WILL OCCUR. DO NOT STORE ANY
POTENTIALLY CORROSIVE COMPOUNDS IN THE VICINITY OF T HE
WATER HEATER.

WARNING

Liquefied petroleum gases/propane gas are heavier than air and will
remain at floor level if there is a leak. Basements, crawl spaces, closets
and areas below ground level will serve as pockets for accumulation of
leaking gas. Before lighting, smell all around the appliance area for gas.
Be sure to smell next to the floor.

IF YOU SMELL GAS:

•

Do not try to light any appliance.

• Do not touch any electric switch; do not use any telephone in your
building.

•

Installation (Locating The Water Heater) continued-

Proper venting practices must be considered when selecting a location for
this water heater. For exact venting specifications, please consult the
Venting section, located on page 9, of these Installation and Operating
Instructions.

This water heater must be located in an area where leakage of the tank, water
line connections, or the combination temperature and pressure relief valve
will not result in damage to the area adjacent to the water heater or to lower
floors of the structure. When such l ocations cannot be av oided, a suitable
drain pan must be installed under the water heater. The drain pan must be no
greater than 1-½ inches

(3.8 cm)

deep and have a mi nimum length and width

of at least four (4) inches

(10.2 cm)

measured from the jacket of the water
heater. The drain pan, as described above, can be purchased from your
plumbing professional. The drain pan must be piped to an adequate drain.
The pi ping m ust be at least 3/4 inch

(1.9 cm)

in diameter and pitched for

proper drainage.

It is recommended that a minimum clearance of four (4) inches

(10.2 cm)

be
provided on the side of the water heater for servicing and maintenance of the
combination temperature and pressure relief valve.

WARNING

DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE
NOT CERTAIN OF T HE FOLLOWING:

•

Liquefied petroleum gases/propane gas and natural gas have an
odorant added by the gas supplier that aids in detection of the gas.

•

Most people recognize this odor as a “sul fur” or “rotten egg” smell.

• Other conditions, such as “odorant fade” can cause the odorant to
diminish in intensity, or “fade”, and not be as readily detectable.

•

If you have a dimini shed sense of smell, or are i n any way unsure of
the presence of gas, immediately contact your gas supplier from a
neighbor’s telephone.

•

Gas detectors are available. Contact your gas supplier or plumbing
professional for more information.

VENTING

Place the draft diverter over the flue opening at the top of the water heater by
inserting the tips of the draft diverter legs into the four (4) holes provided in
the water heater top. On some models, line up the holes in the draft diverter
legs with the holes provided on top of the water heater. Secure the draft
diverter to the water heater with sheet metal screw. (See Figure 5)

Vent piping must be attached to the draft diverter outlet to connect the water
heater to the gas vent or chimney. The following minimum clearances m ust
be followed when connecting vent piping:
a) The vent connector must be the same nominal size as the draft
diverter.
b) The v ent connector should not ex ceed 15 feet

(4.5m)

in length (for
power vent appliances, refer to supplemental instructions), must not
project into the chimney beyond the inner wall and should contain the
least possible number of bends.
c) All horizontal runs should have a minimum rise of ¼ inch per foot

(2.1cm/m)

.
d) Joints of vent connectors shall be securely fastened by sheet metal
screws or other approved methods.
e) All single wall vent connectors must be at least 6”

(15cm)

from
combustible surfaces.
f) Vent connectors made of single-wall metal pipe shall not pass
through any attic, inside wall, concealed space, or any floor. When a
single-wall metal pipe passes through an exterior wall constructed of
combustible material, it shall be guarded at the point of passage by a
ventilated metal thimble at least 4”

(10cm)

larger in di ameter than
the connector. (Consult National Fuel Gas Code, ANSI Z223.1and/or
CAN/CGA B149, Installati on Codes).

A separate vent for each application is strongly recommended. If combined
venting of multiple appliances is necessary or if an unusual situation arises,
consult the National Fuel Gas Code, ANSI Z223.1and/or CAN/CGA B149,
Installation Codes, for sizing and installation information.

WARNING

The vent system must be installed properly. Failure to properly install the
vent system could result in property damage, personal injury, or death.

Combustion Air Supply

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, lumi nous burner flame, causing carboning or sooting of the
combustion chamber, burners and flue tubes with possible damage to the
water heater.

When an ex haust f an is i nstall ed in the sam e room with a heater, sufficient
openings for air must be provided in the walls. Undersized openings will
cause air to be drawn into the room through the chimney, causing
recirculation of combustion products.

Confined Spaces

Confi ned spaces are spac es defi ned as having less than 50 f t.

3

/1000 BTU

(15m3/.29kw)

Unconfined Spaces

In unconfined spaces in buildings, infiltration may be adequate to provide air
for combustion, ventilation and dilution of flue gases. However, in buildings
of tight construction (for example, weather stripping, heavily insulated,
caulked, vapor barrier, etc.), additional air may need to be provided using the
methods described above under CONFINED SPACES: All Air From
Outdoors or SPECIALLY ENGINEERED INSTALLATIONS.

WATER CONNECT IONS

Note: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE
MAIN WATER SUPPLY VALVE.

After shutting off the main water supply, open a faucet to relieve the water
line pressure to prev ent any water f rom leaking out of t he pipes while m aking
the water connections to the water heater. After the pressure has been
relieved, close the f aucet. The COLD water inlet and HOT water outlet are
identified on the top of the water heater. The fittings at the cold water inlet
and hot water outlet are dielectric waterway fittings with 3/4” NPT male
thread. Make the proper plumbing connections between the water heater and
the plumbing system to the house. Install a shut-off valve in the cold water
supply line.

If this water heater is installed in a closed water supply system, such as the
one having a back-flow preventer in the cold water supply, provisions shall be
made to control thermal expansion.

DO NOT

operate this water heater in a
closed system without provisions for controlling thermal expansion. Your
water supplier or local plumbing inspector should be contacted on how to
control this situation

After installation of the water lines, open the main water supply valve and f ill
the water heater. While the water heater is filling, open several hot water
faucets to al low ai r to escape from the water sy stem. When a steady stream
of water flows through the faucets, close them and check all water
connections for possible leaks.

NEVER OPERATE T HE WATER HEATER

WITHOUT FIRST BEI NG CERTAIN IT IS FIL LED WITH WATER.

WARNING

FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4”
TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE
MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM
EXCESSIVE TEMPERATURE AND PRESSURES.

CAUTION

If sweat fittings are to be use,

DO NOT

apply heat to the nipples on top of
the water heater. Sweat the tubing to the adapter before fitting the adapter
to the water connections. It is imperative that heat is not applied to the
nipples contai ning a plastic liner.

WARNING

For protecti on agai nst ex cessiv e temperat ures and pressure, install
temperature and pressure protective equipment required by local codes,
but not less than a combination temperature and pressure relief valve
certified by a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or materials as
meeting the requirements of the Standard for

Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 or the
Standard CAN1-4.4. Temperature and Pressure

and the Standard

CAN1-

4.4, Temperature, Pressure, Temperature and Pressure Relief Valves and
Vacuum Relief Valves

. The combination temperature and pressure relief
valve shall be marked with a max im um set pressure not to exceed the
maximum working pressure of the water heater. The combination
temperature and pressure relief valve shall also have an hourly rated
temperature steam BTU discharge capacity not less than the hourly rating
of the water heater.

Install the com bination tem perature and pressure relief valv e into the
opening provided and marked for this purpose on the water heater.

Note: Some models may already be equipped or suppli ed wit h a
combination temperature and pressure relief valve. Verify that the
combination temperature and pressure relief valve complies with local
codes. If the combination temperature and pressure relief valve does not
comply with local codes, replace it with one that does. Follow the
installation instructions above on this page.

Install a discharge line so t hat water discharged f rom the com bination
temperature and pressure relief valve will exit within six (6) inches

(15.2

cm)

above, or any distance below the structural floor and cannot contact
any li ve electrical part. The discharge line is to be installed t o all ow for
complete drainage of both the combination temperature and pressure
relief v alv e and the discharge l ine. The discharge opening must not be
subjected to blockage or freezing.

DO NOT

thread, plug or cap the
discharge line. It is recommended that a minimum clearance of four (4)
inches

(10.2 cm)

be provided on the side of the water heater for servicing
and maintenance of the combination temperature and pressure relief
valve.

Do not place a valve between the combination temperature and pressure
relief valve and the tank.

14

Installation (Water Connections) continued-

This water heater can deliver scalding temperature water at any faucet in the
system. Be careful whenev er using hot water to avoi d scalding injury.
Certain appliances such as dishwashers and automatic clothes washers m ay
require increased temperature water. By setting the thermostat on this water
heater to obtain the increased temperature water required by these
appliances, the potential for scald injury increases. To protect against injury,
an anti-scald tempering valve should be installed in the water system. This
valve will reduce point of discharge temperature by mixing cold and hot water
in branch supply lines. Such valves are available from the manufacturer of
this water heater or a local

plumbing supplier. Please consult with a plumbing

professional .

WARNING

Hydrogen gas can be produced in an operating water heater that has
not had water drawn from the tank for a long period of time (generally
two weeks or more). Hydrogen gas is extremely flammable. T o
prevent the possibility of injury under these conditions, we
recommend th e hot water fauce t to be open for several minutes at the
kitchen sink before you use any electrical appliance which is
connected to the hot water system. If hydrogen is present, there will
be an unusual sound such as air escaping through the pipes as hot
water begins to flow. Do not smoke or have open flame near the
faucet at the time it is open.

15

GAS CONNECTIONS

The gas supply lines must meet all requi rements of the National Fuel Gas
Code ANSI Z223.1-(Latest Edition) and/or in Canada CAN/CGA B149

THERMOSTAT ADJUSTMENT

The thermostat dial is set to its lowest temperature setting when shipped from
the factory.

Remember that low er temperature settings are more energy

efficient

. Adjust the temperature by turning the thermostat dial. It is

suggested that the starting point setting not be greater than the “

“ mark on

the thermostat dial (approximately 120°F

[49°C]

) as indicated below. Rotate

the thermostat dial

clockwise

to increase

the temperature setting.

Rotate the thermostat di al

counter-clockwise

to decrease the
temperature setting. Adjust the thermostat dial until the minimum acceptable
temperature is achieved (See figure below for approximate temperature
settings).

Figure 2

Hotter water increases the risk of scald injury. Scalding m ay occur within
five (5) seconds at a temperature setting of 135°F

(57°C)

. To protect
against hot water injury, install an anti-scald tempering valve in the water
system. This valve will reduce poi nt of discharge temperature by mixing
cold and hot water in branch water lines. A licensed plumbing
professional or local pl umbi ng authority should be consulted.

Note:

This water heater is equipped with an energy cut out device to
prevent overheating. Should overheating occur or the gas supply fail to
shut off, turn off the manual gas control valve to the appliance and call a
qualified service technician.

Note:

Whenev er the water heater is filled with col d water, condensate
will form on the cool tank surface and drops of water will fall on the hot
burner and combustion chamber surfaces producing a “sizzling” noise.
Condensation is normal and does not indicate a leak. It will disappear
when the tank becomes heated.

DANGER

20

General Operation (continued)-

BURNER FLAME CHECKS

Cast Iron Burner:

At the time of installation and at periodic intervals (not
more than 6 months), a visual check of the main burner and pilot flames
should be made to determine if they are burning properly. For ideal
operation, the gas and air must be properly proportioned. The proper air-gas
mix ture i s obtained by adjusting the air shutter on the m ix er face of the m ain
burner

(See Figure 4).

To adjust for proper burning, loosen the air shutter
nut, rotate shutter to close the opening in the burner then slowly rotate the
shutter until the yellow tips disappear and the flame becomes blue. Tighten
the air shutter nut. Too much air will cause the flame to lift off the burner
ports and create noisy operation. Too little air will result in soot formation.
The main burner flame should light smoothly f rom the pilot.

Steel Burner:

These m odels are equipped with self adjusting air mix ture and

do not have an adjustable air shutter (

See Figure

3). At periodic intervals, a
visual check of the main burner and pilot flames should be made to
determine if they are burning properly. The main burner flame should light
smoothly from the pilot.

MAINTENANCE

The following maintenance should be performed by a qualified service
technician at the minimum periodic intervals suggested below. In some
installations, the maintenance interval may be more frequent depending on
the am ount of use and the operating conditions of the water heater. Regul ar
inspection and maintenance of the water heater and vent-air intake system
will help to insure safe and reliable operation.

1. Annually check the operation of the thermostat.

2. The flow of combustion and ventilation air

MUST NOT

be restricted.

Clear the combustion air openings of any dirt, dust, or other restrictions.

WARNING!

The v entilation air system may be

HOT

.

3. At all times keep the water heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.

4. Bi-annually conduct a visual check of the main and pi lot burner flam es to
determine that they are burning properly. See Burner Flame Check
section on page 19.

WARNING

Water heaters are heat producing appliances. To avoid damage or injury
there shall be no materials stored against the water heater or vent-air intake
system, and proper care shall be taken to av oid unnecessary contact
(especially by children) with the water heater and vent-air intake system.

UNDER NO CIRCUMSTANCES SHALL FLAMMABLE MATERIALS,
SUCH AS GASOLINE OR PAINT THINNER BE USED OR ST ORED IN
THE VICINITY OF T HIS WATER HEATER, VENT-AIR INTAKE SYSTEM
OR IN ANY LOCATION FROM WHICH F UMES COULD REACH THE
WATER HEATER OR VENT-AIR INTAKE SYSTEM.

IMPORT ANT

The water heater should be inspected at a minimum annually by a
qualified service technician for damaged components and/or joints
not sealed. DO NOT operate this water heater if any part is found
damaged or if any joint is found not sealed.

Maintenance (continued)-

5. Annually remove the inner door and main burner assembly to clean
orifices and related parts of any dirt or other foreign material. Inspect the
burner ports for obstructions or debris and clean with a wire brush as
needed. Wire brush and/or vacuum clean the combustion chamber as
needed to remove scale deposits and debris.

NOTE:

It is imperative for
proper operation of the water heater that the inner door be replaced in the
original location.

6. At least once a year, check the combination temperature and pressure
relief valve to insure that the valve has not become encrusted with lime.
Lift the lever at the lever at the top of the valve several times until the
valve seats properly without leaking and operates freely.

7. Monthly drain off a gallon of water to remove silt and sediment.

8. If the combination 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
inspect or on how to correct this situation. Do not plug the combination
temperature and pressure relief valve outlet.

9. A combination sacrif icial anode rod/hot water outlet nipple has been
instal led to extend tank lif e. T he anode rod should be inspected
periodically (every 2 years) and replaced when necessary to prolong tank
life. Water conditions in your area will influence the time interval for
inspection and replacement of the anode rod. Contact the plumbing
professional who installed the water heater or the manufacturer listed on
the rating plate for anode replacement information. The use of a water
softener may incr ease the speed of anode consumption. More f requent
inspection of the anode is needed when using softened (or phosphate
treated) water.

WARNING

When lifting lever of the combination temperature and pressure relief
valve, hot water will be released under pressure. Be careful that any
released water does not result in bodily injury or property damage.

WARNING!

THIS WATER MAY BE HOT.
