Important Instructions
• Do not use this appliance if any part has been under water. Immediately call a qualified service technician. Water
heaters subjected to flood conditions or anytime the gas controls, main burner or pilot have been submerged in
water require replacement of the entire water heater.
• 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 can ignite when exposed to a spark or flame. 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 using any electrical appliance which is connected to the hot water system. If
hydrogen is present, there will probably be an unusual sound such as air escaping through the faucet as water
begins to flow. Do not smoke or have any open flame near the faucet at the time it is open.
The California Safe Drinking Water and Toxic Enforcement Act requires the Governor of California to publish a list of
substances known to the State of California to cause cancer, birth defects, or other reproductive harm, and requires
businesses to warn of potential exposure to such substances.
Warning: This product contains a chemical known to the State of California to cause cancer, birth defects, or other
reproductive harm.

Important: Do not remove any permanent instructions,
labels, or the data label from outside of the water heater
or on the inside of panels.
,, Remove exterior packaging and place installation
components aside.
,, Inspect all parts for damage prior to installation and
start-up.
,, Completely read all instructions before attempting
to assemble and install this product.
,, After installation, dispose of packaging material in
the proper manner.
_lLVapors from flammable liquids will
explode and catch fire causing death or
severe burns.
Do not use or store flammable products
such as gasoline, solvents or adhesives
in the same room or area near the water
heater.
Keep flammable products:
1. far away from heater
2. in approved containers,
3. tightly closed and
4. out of children's reach.
Water heater has a main burner and pilot
flame. The pilot flame:
1. is on all the time and
2. will ignite flammable vapors.
Vapors:
1. cannot be seen,
2. are heavier than air,
3. go a long way on the floor and
4. can be carried from other rooms to
the pilot flame by air currents.
Do not install this water where flammable
products will be stored.
Location Requirements
Carbon Dioxide Poisoning Hazard
Do not install in a mobile home.
Doing so can result in death or carbon
monoxide poisoning.
The Flame Lock TM safety system is designed to reduce
the risk of flammable vapor related fires. The patented
system protects your family by trapping the burning
vapors within the water heater combustion chamber
through the special flame-trap. The burning vapors
literally "burn themselves out" without escaping back
into the room. In the event of a flammable vapor
incident, the Flame Lock TM safety system shuts off the
gas supply to the water heater's burner and pilot
preventing re-ignition of any remaining flammable
vapors in the area. This will permanently disable the
water heater.
Although this water heater is equipped with the Flame
Lock TM safety system, areas where flammable liquids
(gasoline, solvents, liquid propane, butane, etc.) or
other substances which emit flammable vapors are
stored are not suitable for water heater installation.
Never store or use flammable substances in the same
room or area containing a gas water heater. If such
flammables must be used, all gas burning appliances in
the vicinity must be shut off and their pilot lights
extinguished. Open the doors and windows for
ventilation while flammable substances are in use.
If flammable liquids or vapors have spilled or leaked in
the area of the water heater, leave the area immediately
and call the fire department from a neighbor's home. Do
not attempt to clean the spill until all ignition sources
have been extinguished.
Site Location
Select a location near the center of the water piping
system. The water heater must be installed indoors
and in a vertical position on a level surface.
Locate the water heater as close to the chimney or
gas vent as practical. Consider the vent system
piping and combustion air supply requirements
when selecting the water heater location. The
venting system must be able to run from the water
heater to termination with minimal length and
elbows.
* Locate the water heater near the existing gas
piping. If installing a new gas line, locate the water
heater to minimize the pipe length and elbows.
Note: The water heater must be installed according to
all local and state codes or in absence of the local and
state codes with the "National Fuel Gas Code", ANSI
Z223.1 (NFPA54)-Iatest edition.

Gas Requirements
Read the data plate to be sure the water heater is
made for the type of gas you will be using in your
home. This information will be found on the data plate
located near the gas control valve. If the information
does not agree with the type of gas available, do not
install or light. Call your dealer.
Note: An odorant is added by the gas supplier to the
gas used by this water heater. This odorant may fade
over an extended period of time. Do not depend upon
this odorant as an indication of leaking gas.
Gas Piping
The gas piping must be installed according to all local
and state codes or in absence of local and state codes
with the "National Fuel Gas Code", ANSI Z223.1
(NFPA54)-Iatest edition.
Tables 1 and 2 on page 7 are provided as a sizing
reference for commonly used gas pipe materials.
Consult the "National Fuel Gas Code" for the
recommended gas pipe size of other materials.
Refer To Figure 3
Note: When installing gas piping, apply approved pipe
joint compound.
1. Install a readily accessible manual shut-off valve in
the gas supply line as recommended by the local
utility. Know the location of this valve and how to
turn off the gas to this unit.
2. Install a drip leg (if not already incorporated as part
of the water heater) as shown. The drip leg must be
no less than 3 inches long for the accumulation of
dirt, foreign material and water droplets.
3. Install a ground joint union between the gas
valve/thermostat and the manual shut-off valve.
This is to allow easy removal of the gas valve/

the maximum supply pressure as stated on the water
heater's data plate. The minimum supply pressure is for
the purpose of input adjustment.
Gas Pressure Testing
Important: This water heater and its gas connection
must be leak tested before placing the appliance in
operation.
• If the code requires the gas lines to be tested at a
pressure exceeding 14" W.C., the water heater and
its manual shut-off valve must be disconnected
from the gas supply piping system and the line
capped.
_, If the gas lines are to be tested at a pressure less
than 14" W.C., the water heater must be isolated
from the gas supply piping system by closing its
manual shut-off valve.
U.L recognized fuel gas and carbon monoxide (CO)
detectors are recommended in all applications and
should be installed using the manufacturer's
instructions and local codes, rules, or regulations.
Note: Air may be present in the gas lines and could
prevent the pilot from lighting on initial start-up. The gas
lines should be purged of air by a qualified service
technician after installation of the gas piping system.
LP Gas
Explosion Hazard
Have a qualified person make sure L.R
gas pressure does not exceed 13" water

Combustion Air Supply and
Ventilation
Carbon Monoxide Warning
Follow all the local and state codes or in
absence of local and state codes the
"National Fuel Gas Code", ANSI Z223.1
(NFPA 54)- latest edition to properly
install vent system.
Failure to do so can result in death,
explosion, or carbon monoxide poisoning.
Important: Air for combustion and ventilation must not
come from a corrosive atmosphere. Any failure due to
corrosive elements in the atmosphere is excluded from
warranty coverage.
The following types of installation (but not limited to the
following) will require outdoor air for combustion due to
chemical exposure and may reduce but not eliminate
the presence of corrosive chemicals in the air:
,, Beauty shops
,, Photo processing labs
,, Buildings with indoor pools
,, Water heaters installed in laundry, hobby or
craft rooms.
Water heaters installed near chemical storage
areas.
Combustion air must be free of acid-forming chemicals
such as sulfur, fluorine, and chlorine. These elements
are found in aerosol sprays, detergents, bleaches,
cleaning solvents, air fresheners, paint and varnish
removers, refrigerants, and many other commercial and
household products. When burned, vapors from these
products form highly corrosive acid compounds. These
products should not be stored or used near the water
heater or air inlet.
Combustion and ventilation air requirements are
determined by the location of the water heater. The
water heater may be located in either an open
(unconfined) area or in a confined area or small
enclosure such as a closet or small room. Confined
spaces are areas with less than 50 cubic feet for each
1,000 BTUH of the total input for all gas-using
appliances.
Unconfined Space
A water heater in an unconfined space uses indoor air
for combustion and requires at least 50 cubic feet for
each 1,000 BTUH of the total input for all gas
appliances. The table below shows a few examples of
the minimum square footage (area) required for various
BTUH inputs.

Important:
,, The area must be open and be able to provide the
proper air requirements to the water heater. Areas
that are being used for storage or contain large
objects may not be suitable for water heater
installation.
,, Water heaters installed in open spaces in buildings
with unusually tight construction may still require
outdoor air to function properly. In this situation,
outside air openings should be sized the same as
for a confined space.
• Modern home construction usually requires
supplying outside air into the water heater area.
Confined Space
For the correct and proper operation of this water
heater, ample air must be supplied for the combustion,
ventilation and dilution of flue gases. Small enclosures
and confined areas must have two permanent openings
so that sufficient fresh air can be drawn from outside of
the enclosure. One opening shall be within 12 inches of
the top and one within 12 inches of the bottom of the
enclosure as shown in Figure 4.
The size of each opening (free area) is determined by
the total BTUH input of all gas utilization equipment
(i.e., water heaters, furnaces, clothes dryers, etc.) and
the method by which the air is provided. The BTUH
input can be found on the water heater data plate.
Additional air can be provided by two methods:
1. All Air from Inside the Building.
2. All Air from Outdoors.
12" inch
maximum
All Air from Inside the Building
When additional air is to be provided to the confined
area from additional room(s) within the building, the
total volume of the room(s) must be of sufficient size to
properly provide the necessary amount of fresh air to
the water heater and other gas utilization equipment in
the area. If you are unsure that the structure meets this
requirement, contact your local gas utility company or
other qualified agency for a safety inspection.
Each of the two openings shall have a minimum free
area of 1 square inch per 1,000 BTUH of the total input
rating of all gas utilization equipment in the confined
area, but not less than 100 square inches (Figure 5).

All Air from Outdoors
Outdoor fresh air can be provided to a confined area
either directly or by the use of vertical and horizontal
ducts. The fresh air can be taken from the outdoors or
from crawl or attic spaces that freely communicate with
the outdoors. Attic or crawl spaces cannot be closed
and must be properly ventilated to the outside.
Ductwork must be of the same cross-sectional area as
the free area of the opening to which they connect. The
minimum dimension of rectangular air ducts cannot be
less than 3 inches.
The size of each of the two openings is determined by
the method in which the air is to be provided. Refer to
Table 4 to calculate the minimum free area for each
opening. Figures 6, 7, and 8 are typical examples of
each method.
Louvers and Grilles
In calculating free area for ventilation and combustion
air supply openings, consideration must be given to the
blocking effect of protection louvers, grilles, and
screens. These devices can reduce airflow, which in
turn may require larger openings to achieve the
required minimum free area. Screens must not be
smaller than 1/4-inch mesh. If the free area through a
particular design of louver or grille is known, it should
be used in calculating the specified free area of the
opening. If the design and free area are not known, it
can be assumed that most wood louvers will allow
20 - 25% of free area while metal louvers and grilles will
allow 60 - 75% of free area.
Louvers and grilles must be locked open or
interconnected with the equipment so that they are
opened automatically during equipment operation.
Keep louvers and grilles clean and free of debris or
other obstructions.
