Your safety and the safety of others are very important.
We have provided many important safety messages in this manual and on your appliance. Always read and obey all
safety messages.
This is the safety alert symbol.
This symbol alerts you to potential hazards that can kill or hurt you and others.
All safety messages will follow the safety alert symbol and either the word "DANGER" or
"WARNING" These words mean:
You can be killed or seriously injured if you don't
immediately follow instructions.
You can be killed or seriously injured if you don't
follow instructions.
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you

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.
This appliance can cause low-level exposure to some of the substances listed, including formaldehyde, carbon
monoxide, and soot.

having jurisdiction over your installation.
Consumer Responsibilities
This manual has been prepared to acquaint you with
the installation, operation and maintenance of your gas
water heater and provide important safety information in
these areas.
Read all of the instructions thoroughly before
attempting the installation or operation of this water
heater. Keep this manual for future reference.
Service to the Flame Lock TM safety system should
only be performed by a qualified service technician.
The manufacturer of this water heater will not be liable
for any damages caused by failure to comply with the
installation and operating instructions outlined in this
manual.
If you lack the necessary skills required to properly
install this water heater or you have difficulty following
the instructions, you should not proceed but have a
qualified person perform the installation of this water
heater. Massachusetts code requires this water heater
to be installed in accordance with Massachusetts
Plumbing and Fuel Gas Code 248 CMR section 2.00
and 5.00.
A data plate identifying your water heater can be found
next to the gas control valve/thermostat. When referring
to your water heater always have the information listed
on the data plate readily available.
Unpacking the Water Heater
Excessive Weight Hazard
Use two or more people to move and
install water heater.
Failure to do so can result in back or
other injury.
Removing Packaging Materials
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.

,, The water heater should be located in an area not
subject to freezing temperatures. Water heaters
located in unconditioned spaces (i.e., attics,
basements, etc.) may require insulation of the water
piping and drain piping to protect against freezing.
The drain and controls must be easily accessible
for operation and service. Maintain proper
clearances as specified on the data plate.
• Do not locate the water heater near an air-moving
device. The operation of air-moving devices such
as exhaust fans, ventilation systems, clothes
dryers, fire-places, etc., can affect the proper
operation of the water heater. Special attention
must be given to conditions these devices may
create. Flow reversal of flue gases may cause an
increase of carbon monoxide inside of the dwelling.

combustible floor.
Important: If installing over carpeting, the carpeting
must be protected by a metal or wood panel beneath
the water heater. The protective panel must extend
beyond the full width and depth of the water heater by
at least 3 inches (76.2mm) in any direction or if in a
alcove or closet installation, the entire floor must be
covered by the panel.
Figure 2 may be used as a reference guide to locate
the specific clearance locations. A minimum of 24
inches of front clearance should be provided for
