At the time of manufacture this water heater was provided with a combination temperature-pressures relief
valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production
of listed equipment or materials, as meeting the
requirements for Relief Valves and Automatic Gas
Shutoff Devices for Hot Water Supply Systems, and I
the latest edition of ANSI Z21.22 and the code require- I
ments of ASME. If replaced, the valve must meet the I
requirements of local codes, but not less than a combination temperature and pressure relief valve certified
as meeting the requirements for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water Supply I
Systems, ANSI Z21.22 by a nationally recognized test- [
ing laboratory that maintains periodic inspection of
production of listed equipment or materials.
I 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 divided by 1000 x 3415 equal

then
the installation must be accomplished in a way that
the ignitor and main burner flame are elevatedfrom
the floor at least 18 inches. While this may reduce the
chances of flammable vapors from a floor spill being
ignited, gasoline and other flammable substances
should never be stored or used in the same room or
area containing a gas water heater or other open
flame or spark producing appliance,
NOTE: Flammable vapors may be drawn by air currents
from other areas of the structure to the appliance,
must
not be removed from it's designated opening or I
plugged.
The temperature-pressure
relief valve must be
installed directly into the fitting of the water heater
designated for the relief valve. Position the valve
downward and provide tubing so that any discharge
will 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. Excessive length, 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 discharge drain unless a 6 air gap is provided. To prevent bodily injury, hazard to life, or property
damage, the relief valve must be allowed to discharge
water in quantities should circumstances demand. If
the discharge pipe is not connected to a drain or other
suitable means, the water flow may cause property
damage.
The Discharge Pipe:
• Must not be smaller in size than the outlet pipe size
of the valve, or have any reducing couplings or
other restrictions.
• Must not be plugc_edor blocked.
• Must be of matenal listed for hot water distribution.
AWARNING
If this water heater will be used in beauty shops,
barber shops, cleaning establishments, or self-setvice 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 Code, ANSI Z223.1, also referred to as NFPA

AWARNING
Do not install in a confined area such a closet, unless
you provide ventilation
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 ventilation air can result in a fire
or explosion and can cause DEATH, SERIOUS BODILY
INJURY,OR PROPERTY DAMAGE,
This water heater must not be installed directly on
carpeting. 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 by the panel. Failure to
heed this warning may result in a fire hazard.

_,WARNING
A'WARNING
The power direct 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
ventin_ system can result in asphyxiation, a fire or
explosion and can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a
temperature 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 hol
water than others. These include the elderly, children
the infirm, or physicall_//mentally handicapped. It
anyone using hot water in your home fits into one of
these groups or 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
addition 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 manufacturers instructions for installation of the valves. Before changing
the factory setting on the thermostat,
read the
"Temperature Regulation" section in this manual.
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 direct vented water
heater. Alteration of any part of the factory-furnished vent assembly could result in improper operation due to restriction of flue gases, spillage of flue
gases and may cause carbon monoxide poisoning.
&WARNING
• The appliance and its individual shutoff valve must
be disconnected from the gas supply piping system
during any pressure testing of the gas system at
test pressures in excess ofl/2 pound per square
inch (3.5kPa).
= The appliance must be isolated from the gas supply piping system by dosing its individual manual
shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal or
less than 1/2 pound per square inch (3.5kPa).
&WARNING
Soot build-up indicates a problem that requires correction 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 PROPERTYDAMAGE.
AWARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS[: Propane (L.P.) gas is heavier than air.
Should there be a leak in the system, the gas will settie near the ground. Basements, crawl spaces, skirted
areas under manufactured (mobile) homes (even
when ventilated), closets and areas below ground
level will serve as pockets for the accumulation of
this gas. Before attempting to operate the water
heater or turning on a nearby electrical light switch,
be absolutely sure there is no accumulatecl 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.

AWARNING
The water heater must be properly vented to the
outdoors. Never operate the water heater unless it is
vented to the outdoors and has adequate air supply
to avoid risks of improper operation, explosion or
asphyxiation,
INSULATING JACKETS: When installing an external
water heater insulation jacket on a gas water heater:
• DO NOT cover the temperature-pressure relief valve.
• DO NOT put insulation over any part of the top of
the gas water heater.
• DO NOT put insulation over the gas control valve or
gas control valve/burner cover, or any access areas
to the burner.
• DO NOT let insulation around the gas water heater
to get within 8 inches of the floor (access for servicing the burner).
• DO NOT cover or remove operating instructions,
and safety related warning labels and materials
affixed to the water heater.
Failure to heed this will result in the possibility of a
fire or explosion.
AWARNING
Minimum clearances between the water heater and
combustible construction are iT at the sides and rear,
6" at the front, and 0" 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 label on the water heater
adjacent to the gas control valve for all clearances,
AWARNING
Flood damage to a water heater may not be readily
visible or immediately detectible. However, over a
period of time a flooded water heater will create
dangerous conditions which can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.

•,WARNING
HYDROGEN GAS: Hydrogen gas can be produced in
a hot water system that has not been used for a
long period of time (generally two weeks or more),
Hydrogen gas is extremely flammable and explosive,
To prevent the possibility of injury under these conditlons, 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 dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar 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 is open.

WATER HEATERS E_EAK:
Installation ofl
the water heater must be accomplished in such a l
manner that if the tank or any connections should J
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 hardware store. Such a drain pan must 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. Drain pan depth must allow
access to the outer doors for servicing the ignitor
and burner. Under no circumstances is the manufacturer to be held liable for any water damage in connection with this water heater.

Locating the New Water
Heater
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 an 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 hardware store. Such a drain pan must 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.Drain pan depth must allow I
access to the outer doors for servicing the ignitor
and burner. Under no circumstances is the manufac-
You should carefiaUychoose an indoor location for the new

A WARNING
iNSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (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.), all of which emit
flammable vapors, may be improperly stored or
used in such areas. The gas water heater ignitor or
main burner can ignite 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, I
then the installation must be accomplished in a [
way that the ignitor and main burner flame are ele- I

every 90 ° elbow. See page 19 for vent chart,
• Vent piping cannot slope downward and horizontal runs
require 1/,,, per five foot rise. ALlhorizontal runs require
adequate support at 3'/2 foot intervals and vertical runs
supported at 5 foot intervals,
• The water heater requires its own (separate)venting system,
It cannot be connected to an existing vent pipe or chimney. It
must terminate to the outdoors. Whenever possibleterminate
the vent on the leeward side of the building through an outside wall. NOTE: Condensation maybe created, at times, as

surfacesinproximitytotheventcapmayoccur,
used in the same room or area containing agas
water heater or other open flame or spark producing appliance.
NOTE: Flammable vapors may be drawn by air currents
from other areas of the structure to the appliance.
AWARNING
The power direct vent water heater requires its own
(separate) venting system. R 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, SERIOUSBODILY INJURY,OR PROPERTY DAMAGE.
AWARNING
Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.) in addition to being highly flammable
in many cases, will also change to corrosive
hydrochloric acid when exposed to the combustion
products of the water heater. The results can be
hazardous, and also cause product failure.
e The water heater comesequipped with a 7 foot power cord
which can be used to connect to a 110/120 volt power
source if(l) local codes allow, and (2) there is a three prong
receptacle available, This unit must have a grounded outlet to operate,
AWARNING

A WARNING
At the time of manufacture this water heater was provided with a combination tempereture-pressures relief valve
certified by a nationally recognized testing laboratory that
maintains periodic inspection of production of listed
equipment or materials, as meeting the requirementsfor
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 less than a combination temperature and pressure
relief valve certified as meeting the requirements for
Relief Valves and Automatic Gas Shutoff Devicesfor Hot

of production of listedequipment or materials.
The valve must be marked with a maximum set pressure
not to exceedthe marked hydrostaticworking pressureof
the water heater (150 Ibs./sq. in.) and a dischargecapacity
not lessthan the water heater input rate as shown on the
model rating plate. (Electric heaters - watts divided by
1000 x 3415 ec_ualBTU/Hr.rate.)
Your local jurisdictional authority, while mandating the!
use of a temperature-pressurerelief valve complying with
ANSI Z21.22 and ASME, may require a valve model different from the one furnished with the water heater.
Compliancewith such local requirementsmust be satisfied
by the installer or end user of the water heater with a
Iocallyprescribed temperature-pressure relief valve
installed in the designated opening in the water heater in
The temperature-pressure relief valve must be manually operated at least once a year. Caution should be
taken to ensure that (1) no one is in front of or
around the outlet of the temperature-pressure relief
valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property
damage because the water may be extremely hot.
If after manually operating the valve, it fails to cornpletely reset and continues to release water, immediately close the cold water inlet to the water heater,
follow the draining instructions, and replace the
temperature-pressure relief valve with a new one.

chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants,
swimming pool chemicals, calcium and sodium chloride, waxes, bleach, and process chemicals are typical compounds which are potentially corrosive.
At least once a year a visual inspection should be made of
the main burner and pilot burner. The drawing is for your
reference.
You should check for sooting which is not normal and will
impair proper combustion.
Obstructed or deteriorated vent systems may present a serious health risk or asphyxiation.

THERMAL EXPANSION
Whenever
Water supply systems may, because of high line pressure, fre-
the water heater is filled with cold water, a certain
amount of condensation will form while the burner is on. A
water heater may appear to be leaking when in fact the water
is condensation. This usually happens when:
quent cut-offs, the effects of water hammer and others, have
installed devices such as pressure reducing valves, check
valves, back flow preventers, etc. to control these types of
problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices
cause the water system to be closed. As water is heated, it
expands (thermal expansion) and closed systems do not allow
for the expansion of heated water.

The water heater must be sized properly to meet the family's
demands for hot water including dishwashers, washing
machines and shower heads.
STRANGE
Excessive condensation may be noticed during the winter and
early spring months when incoming water temperatures are at
their lowest,
Possible noises due to expansion and contraction of some
metal parts during periods of heat-up and cool-down do not
represent harmful or dangerous conditions.
Good venting is essential for a gas fired water heater to operate properly as well as to carry away products of combustion
and water vapor,
Condensation causes sizzling and popping with the burner
area during heating and cooling periods and should be considered normal. See "Condensation" section.
SMOKE/ODOR
It is not uncommon to experience a small amount of smoke
and odor during the initial start-up. This is due to burning off
of oil from metal parts, and will disappear in a short while.

SMELLY WATER
HIGH TEMPERATURE SHUT OFF SYSTEM
In each glasslined water heater there is installed at least one
anode rod (see parts section) for corrosion protection of the
tank. Certain water conditions will cause a reaction between
this rod and the water. The most common complaint assoeiated with the anode rod is one of a "rotten egg smell". This
odor is derived from hydrogen sulfide gas dissolved in the
water. The smell is the result of four factors which must all be
present for the odor to develop:
This water heater is equipped with an automatic gas shut off
system. The high temperature shut offis built into the gas
control valve. This system shuts off the gas supply to the
water heater burners when high water temperatures are present. It is non-resettable. If the high temperature shut off
activates, the gas control valve must be replaced. If this were
to occur, turn "OFF" the entire gas supply to the water heater.

"AIR" IN HOT WATER FAUCET'S
AWARNING
HYDROGEN GAS: Hydrogen gas can be produced in
a hot water system that has not been used for a
long period of time (generally two weeks or more).
Hydrogen gas is extremely flammable and explosive. TO prevent the possibility 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 dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar 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 is open.
