_,VQARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQ-
UIDS (VAPORS) ARE LIKELY TO BE PRESENT OR
STORED (GARAGES, STORAGE, AND UTILITY AREAS,
ETC): Flammable liquids (such as gasoline, solvents,
propane(LP) or butane, etc.), allof whichemit flammable
vapors, may be improperly stored or used in such areas.
The gaswater heater pilot light or main burner canignite
such vapors. The resulting flashback and fire can cause
death or serious burns to anyone in the area, as well as
property damage.
If installation in such areas is your only option, then the
installation must be accomplishedin a way that the pilot
flame and main burner flame are elevated from the floor
at least 18 inches.While this may reduce the chancesof
flammable vaporsfrom a floor spillbeing ignited, gasoline
and other flammable substancesshouldnever bestored or
used in the same room or area containing a gas water
heater or other open flame or sparkproducingappliance.
NOTE: Flammable vapors may be drawn by air currents
from other areasof the structure to the appliance.
_,WARNING
If this water heater will be used in beauty shops,barber
shops,cleaning establishments, or self-service laundries
with dry cleaning equipment, it is imperative that the
water heater or water heaters be installed sothat com-
bustion and ventilation air be taken from outside these
areas. Refer to the "Locating The New Water Heater"
section of this manual and also the latest edition of the
National Fuel Gas Code, ANSI Z223.1, also referred to as
NFPA 54 for specificsprovidedconcerningair required.
_,WARNING I
A fire can start if combustible materials suchas clothing,
cleaningmaterials, or flammable liquidsare placed against
or next to the water heater.
_,WARNING
At the time of manufacture this water heater was provid-
edwith a combination temperature-pressures relief valve
certified by a nationally recognized testing laboratory
that maintains periodic inspectionof production of listed
equipment or materials, as meeting the requirements
for Relief Valves and Automatic Gas Shutoff Devices for
Hot Water Supply Systems, and the latest edition of
ANSI Z21.22 and the code requirements of ASME. If
replaced, the valve must meet the requirements of local
codes,but not lessthan a combination temperature and
_ressure relief valve certified as meeting the require-
ments for Relief Valves and Automatic Gas Shutoff
Devicesfor Hot Water Supply Systems, ANSI Z21.22 by
a nationally recognized testing laboratory that maintains
_eriodic inspection of production of listed equipment or
materials.
The valve must be marked with a maximum set pressure
not to exceed the marked hydrostatic working pressure
of the water heater (150 Ibs./sq. in.) and a discharge
capacity not less than the water heater input rate as
shown on the model rating plate. (Electric heaters -
watts dividedby 1000x 3415 equal BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the
use of a temperature-pressure relief valve complying
with ANSI Z21.22 and ASME, may require a valve model
different from the one furnishedwith the water heater.
Compliance with such local requirements must be satis-
fied by the installer or end user of the water heater with
a locally prescribed temperature-pressure relief valve
installed in the designatedopeningin the water heater in
daceof the factory furnishedvalve.
For safe operation of the water heater, the relief valve
must not be removed from it's designated opening or
plugged.
The temperature-pressure relief valve must be installed
directly into the fitting of the water heater designated
for the relief valve. Positionthe valve downwardand pro-
vide tubing so that any dischargewill exit only within 6
inches above, or at any distance below the structural
floor. Be certain that no contact is made with any live
electrical part. The discharge opening must not be
blocked or reduced in size under any circumstances.
Excessivelength, over 30 feet, or use of more than four
elbows can cause restriction and reduce the discharge
capacity of the valve.
No valve or other obstruction is to be placed between
the relief valve and the tank. Do not connect tubing
directly to dischargedrain unlessa 6" air gap isprovided.
To prevent bodily injury, hazard to life, or property dam-
age, the relief valve must be allowed to dischargewater
in quantities should circumstances demand. If the dis-
charge pipe isnot connected to a drain or other suitable
means, the water flow may causeproperty damage.
The DischargePipe:
• Must not be smaller in sizethan the outlet pipe sizeof
the valve, or have any reducing couplings or other
restrictions.
• Must not be pluggedor blocked.
• Must be of material listedfor hot water distribution.
• Must be installed so as to allow complete drainage of
both the temperature-pressure relief valve, and the
dischargepipe.
• Must terminate at anadequate drain.
• Must not have any valve between the relief valve and
tank.
Safety Precautions
AWARNING
A gas water heater cannot operate properly without the
correct amount of air for combustion. Do not install in a
confined area such a closet, unless you provide air as
shown in the "Locating The New Water Heater" section.
Never obstruct the flow of ventilation air. If you have any
doubts or questions at all, call your gas company. Failure
to provide the proper amount of combustion air can result
in a fire or explosion and can cause DEATH, SERIOUS
BODILY INJURY, OR PROPERTY DAMAGE.
_,WARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
perature which will satisfy clothes washing, dish washing,
and other sanitizing needs can scald and permanently
injure you upon contact. Some people are more likely to
be permanently injured by hot water than others. These
include the elderly, children, the infirm, or physicallylmen-
tally handicapped. If anyone using hot water in your home
fits into one of these groups_r if there is a local code or
state law requiring a certain temperature water at the hot
water tap, then you must take special precautions. In addi-
tion to using the lowest possible temperature setting that
satisfies your hot water needs, a means such as a mixing
valve, should be used at the hot water taps used by these
people or at the water heater. Mixing valves are available
at plumbing supply or hardware stores. Follow manufac-
turers instructions for installation of the valves. Before
changing the factory se_ing on the thermostat, read the
"Temperature Regulation" section in this manual.
_,WARNING
This water heater must not be installed directly on car-
peting. Carpeting must be protected by a metal or wood
panel beneath the appliance extending beyond the full
width and depth of the appliance by at least 3 inches
(76.2mm) in any direction, or if the appliance is installed
in an alcove or closet, the entire floor must be covered b
the panel. Failure to heed this warning may result in
fire hazard.
_WARNING
The power vent water heater requires its own (separate)
venting system. It cannot be connected to an existing vent
pipe or chimney, it must be terminated to the outdoors.
Failure to properly install the venting system can result in
asphyxiation, a fire or explosion and can cause DEATH, SE-
RIOUS BODILY INJURY, OR PROPERTY DAMAGE.
AWARNING
No vent damper installation is compatible with this power
vented water heater design. No vent damper, whether it is
operated thermally or otherwise is to be installed on this
power vented water heater. Alteration of any part of the fac-
tory-furnished vent assembly could result in improper oper-
ation due to restriction of flue gases, spillage of flue gases
and may cause carbon monoxide poisoning.
AWARNING
Soot build-up indicates a problem that requires correc-
tion before further use. Turn "off" gas to water heater
and leave "off" until repairs are made, because failure to
correct the cause of the sooting can result in a fire or
explosion causing DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
_,WARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS]: Propane (L.R) gas is heavier than air. Should
there be a leak in the system, the gas will settle near the
ground. Basements, crawl spaces, skirted areas under
mobile homes (even when ventilated), closets and areas
below ground level will serve as pockets for the accumula-
tion of this gas. Before attempting to light or relight the
water heater's pilot or turning on a nearby electrical light
switch, be absolutely sure there is no accumulated gas in
the area. Search for odor of gas by sniffing at ground level
in the vicinity of the appliance. If odor is detected, follow
steps indicated at "For Your Safety" on the cover page of
this manual then leave the premises.
_,WARNING
• The appliance and its individualshutoff"valvemust bedis-
connected from the gassupplypiping systemduring any
pressure testing of the gassystem at test pressuresin
excessof I/2 pound per squareinch(3.5kPa).
• The appliance must be isolatedfrom the gassupplypip-
ing system by closingits individualmanual shutoff valve
during any pressuretesting of the gas supplypiping sys-
tem at test pressuresequal or lessthan 1,2 pound per
squareinch (3.5kPa).
_,WARNING
Chemical vapor corrosion of the flue and vent system
may occur if air for combustion contains certain chemical
vapors. Spray can propellants, cleaning solvents, refrigera-
tor and air conditioner refrigerants, swimming pool
chemicals, calcium and sodium chloride, waxes, bleach,
and process chemicals are typical compounds which are
potentially corrosive.
AWARNING
Obstructed or deteriorated vent systems may present a
serious health risk or asphyxiation.
Safety Precautions continued on page 4.

Safety Precautions
AWARNING
The water heater wi_talled must be prop- I
erly vented to a chimney which terminates outdoors. I
Never operate the water heater unlessit is vented to the I
outdoors and has adequate air supply to avoid risks of I
improper operation,explosionor asphyxiation. J
AWARNING
Minimum clearances between the water heater and com-
bustible construction are 0" at the sides and rear, 5" at the
front, and fl" from the vent pipe. Clearance from the top
of the jacket is 14" on most models. Note that a lesser
dimension may be allowed on some models. Refer to the
labelon the water heater adjacent to the gascontrol valve
for all clearances.
I AWARN,NG I
Do not usethis appl_of it hasbeen under I
water. Immediately calka Sears Service Technician to I
inspectthe applianceandto replace the gascontrol or any I
part ofthe burner systemwhich hasbeen under water. I
AWARNING J
Vent termination must not be within 4 feet of any items J
such as gas meters, gasvalves or other gas regulating
equipment.
A CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplishedin sucha manner
that if the tank or any connectionsshould leak, the flow of
water will not cause damage to the structure. For this
reason, it is not advisableto install the water heater inan
attic or upper floor.When suchlocationscannot beavoid-
ed, a suitable drain pan should be installed under the
water heater. Drain pansare availableat your localSears
store. Sucha drain pan must be not greater than 1½inch-
es deep, have a minimum length and width of at least 2
inches greater than the water heater dimensions and
must be piped to an adequate drain. The pan must not
restrict combustion air flow. Under no circumstances is
the manufacturer or Searsto be held liable for anywater
damage in connectionwith thiswater heater.
AWARNING
HYDROGEN GAS: Hydrogengascan be producedin a hot
water system that hasnot been usedfor a long period of
time (generally two weeks or more). Hydrogen gas is
extremely flammable and explosive.To prevent the possi-
bility of injury under these conditions,we recommend the
hot water faucet be opened for several minutes at the
kitchen sink before any electrical appliances which are
connected to the hot water system are used (such as a
dishwasheror washing machine). If hydrogen gas is pre-
sent,there will probablybe an unusualsoundsimilar to air
escaping through the pipe as the hot water faucet is
opened. There must be no smoking or open flame near
the faucet at the time it isopen.
AWARNING
INSULATING JACKETS: When installing an external
water heater insulationjacket on a gaswater heater:
DO NOT cover the temperature-pressure relief valve.
DO NOT put insulation over any part of the top of the
gaswater heater.
DO NOT put insulation over the gascontrol valve or gas
control valve/burner cover,or any accessareas to the
burner.
DO NOT let insulationaround the gaswater heater to
get within 8 inches of the floor (air must get to the
burner).
DO NOT cover or remove operating instructions, and
safetyrelated warning labelsand materials affixed to the
water heater.
:allure to heed this will result in the possibilityof a fire or
explosion.

the water be turned off to the entire
house.
®
Q Disconnect the vent pipe from the draft hood where
they connect to the water heater. In most installations
the vent pipe can be lifted off after any screw or other
attached devices are removed. Dispose of the draft
hood. The new water heater has the draft hood which
must be used for proper operation,
Q a. If you have copper piping to the water
® ®
heater, the two copper water pipes can
be cut with a hacksaw approximately
four inches away from where they con-
nect to the water heater. This will avoid
cutting off the pipes too short.
Additional cuts can he made later if nec-
essary. Disconnect the temperature-pres-
sure relief valve drain line. When the
water heater is drained, disconnect the
hose from the drain valve. Close the
drain valve. The water heater is now
completely disconnected and ready to be
removed.
QCheck again to make sure the gas supply
is "OFF" to the water heater. Then dis-
connect the gas supply connection from
the gas control valve.
Q Attach hose the heater drain
a to water
valve and put the other end in a floor
drain or outdoors. Open the water heater
drain valve. Open a nearby hot water
faucet which will relieve pressure in the
water heater and speed draining.
I AWARNING
The water passingou_ve may be extremely
hot. To avoidbeing scalded,make sure all connectionsare
tight and that the water flow is directed away from any
person.
If
G b. you galvanized pipe to water
have the
heater, loosen the two galvanized pipes
with a pipe wrench at the union in each
line. Also disconnect the piping remain-
ing to the water heater. These pieces
should be saved since they may be need-
ed when reconnecting the new water
heater. Disconnect the temperature-pres-
sure r_lief valve drain line. When the
water nearer is drained, disconnect the
hose from the drain valve. Close the
drain valve. The water heater is now
completely disconnected and ready to be
removed.

Installation Instructions
Locating the New Water
Heater
You should carefully choose an indoor location for the new water
heater, because the placement is a very important consideration
for the safety of the occupants in the building and for the most
economical use of the appliance. This water heater is not for
use in mobile homes or outdoor installation.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
1. The location selected should be indoors as close as practical
to the vent termination point, and as centralized with the
water piping system as possible. The water heater, as all water
heaters, will eventually leak. Do not install without adequate
drainage provisions where water flow will cause damage.
2. If vented through an outside wall or through the roof the
vent piping cannot exceed a total of 35 feet including vertical
and horizontal runs and have no more than 3 elbows. It can-
not slope downward and horizontal runs require ¼" per foot
rise. All horizontal runs require adequate support at 3_ feet
intervals.
3. The water heater requires i_s own (separate) venting system.
It cannot be connected to an existing vent pipe or chimney.
It must terminate to the outdoors. Whenever possible termi-
nate the vent on the leaward side of the building if vented
through an outside wall. NOTE: Condensation may be cre-
ated, at times, as the combustion gases exit the vent cap
and discoloration of surfaces in proximity to the vent cap
may occur.

4. The water hearer comes equipped with a 5 foot power cord
which can be used to connect to a 110/120 volt power
source if (1) local codes allow, and (2) there is a three prong
receptacle available.
A WARNING
Donot usean extensioncord.If there isnot a suitablerecepta-
cleand/or localcodesprohibituseof a powercord,fieldwiring

ACAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the
water heater must be accomplished in such a manner that if
the tank or any connections should leak, the flow of water
will not cause damage to the structure. For this reason, it is
not advisable to install the water heater in at attic or upper
floor. When such locations cannot be avoided, a suitable
drain pan should be installed under the water heater. Drain
pans are available at your local Sears store. Such a drain pan
must be not greater than I% inches deep, have a minimum
length and width of at least 2 inches greater than the water
heater dimensions and must be piped to an adequate drain.
The pan must not restrict combustion air flow. Under no cir-
cumstances is the manufacturer or Sears to be held liable
for any water damage in connection with this water heater.
5. The location selection must provide adequate clearances for
servicing and proper operation of the water heater.

AWARNING
A gaswater heater cannot operate properly without the cor-
rect amount of air for combustion. Do not install in a con-
fined area such a closet, unless you provide air as shown in
the "Locating The New Water Heater" section. Never
obstruct the flow of ventilation air If you have any doubts or
questions at all, call your gascompany. Failure to provide the
proper amount of combustion air can result in a fire or explo-
sion and can cause DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
_iWARNING
If this water heater will be used in beauty shops, barber shops,
cleaning establishments, or self-service laundries with dry
cleaning equipment, it is imperative that the water heater or
water heaters be installed so that combustion and ventilation
air be taken from outside these areas. Refer to the "Locating
The New Water Heater" section of this manual and also the
latest edition of the National Fuel Gas Cede, ANSI Z223.1, also
referred to as NFPA 54 for specifics provided concerning air
required.

Combustion Air and Ventilation
for Appliances Located in
Unconfined Spaces
Unconfined Space is a space whose volume is not less than 50 cubic
feet per 1,000 Btu per hour of the aggregate input rating of all appli-
ances installed in that space. Rooms communicating directly with the
space in which the appliances are installed, through openings not fur-
nished with doors, are considered a part of the unconfined space.
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 insuhted, caulked, vapor barrier, etc.), additional air
may need to be provided using the methods described in Combustion
Air and Ventilation for Appliances Located in Confined Spaces.
Combustion Air and Ventilation
1. When directly communicating with the outdoors, each opening
shall have a minimum free area of 1 square inch per 4,000 BTU
per hour of total input rating of all equipment in the enclosure.
(See Figure 7.)
2. When communicating with the outdoors through vertical ducts,
each opening shall have a minimum flee area of 1 square inch
per 4,000 BTU per hour of total input rating of all equipment in
the endosure. (See Figure 8.)

installed in that space.
a. ALL AIR FROM INSIDE BUILDINGS:
(See Page 9 Figure 1, and Figure 6 below)
The confined space shall be provided with two permanent open-
ings communicating directly with an additional room(s) of suffi-
cient volume so that the combined volume of all spaces meets the
criteria for an unconfined space. The total input of all gas utiliza-
tion equipment installed in the combined space shall be considered
in making this determination. Each opening shall have a minimum
free area of one square inch per 1,000 BTU per hour of the total
input rating of all gas utilization equipment in the confined space,
but not less than 100 square inches. One opening shall commence
within 12 inches of the top and one commencing within 12 inches
of the bottom of the enclosure.

b. ALL AIR FROM OUTDOORS: (see Figures 7-9)
The confined space shall be provided with two permanent open-
ings, one commencing within 12 inches of the top and one com-
mencing within 12 inches from the bottom of the enclosure.
The openings shall communicate directly, or by ducts, with the
outdoors or spaces (crawl or attic) that freely communicate with
the outdoors.

4. When ducts are used, they shatl be of the same cross-sectional area
as the free area of the openings to which they connect. The mini-
mum short side dimension of rectangular air ducts shall not be
less than 3 inches. (See Figure 9.)
5. Louvers and Grilles: In calculating free area, consideration shall be
given to the blocking effect of louvers, grilles or screens protect-
ing openings. Screens used shall not be smaller than ¼ inch mesh.
If the free area through a design of louver or grille is known, it
should be used in calculating the size opening required to provide
the free area specified. If the design and free area is not known, it
may be assumed that wood louvers will be 20-25 percent free area
and metal louvers and grilles will have 60-75 percent free area.
Louvers and grilles shall be fixed in the open position or inter-
locked with the equipment so that they are opened automatically
during equipment operation.
6. Special Conditions Created by Mechanical Exhausting or
Fireplaces: Operation of exhaust Fans, ventilation systems, clothes
dryers or fireplaces may create conditions requiring special atten-
tion to avokl unsatisfactory operation of installed gas utilization
equipment.
