Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank fo
period of time (generally two weeks or more) . Hydrogen gas is extremely flammable. To prevent the possibility of injury
under these conditions, we recomm end the hot water faucet to be open for several minutes at the kitchen sink before
you use any electrical appliance, which is connect to the hot water system. If hydrogen is present, there will be unusual
sounds such as air escaping through the pipes as hot water begins to f low. Do not smoke or have open flame near the
moisture/water or dirt/scale inside the gas line. Commonly this check is done at the lowest point in the gas
distribution system prior to gas burning appliances.
Do not use this appliance if any external part to the tank has been submerged in water. You should contact a qualified
service technician to inspect the appliance and to replace any part of the control system including the combination gas
control which has been submerged in water. See the Gas Connections section of this manual before servicing or replacing
a water heater that has had any external part to the tank submerged in water.
Basement s, craw l spaces, closets and areas below ground level w ill serve as pockets for accumulat ion of
leak in g gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to t he f loor.
I F Y O U S MELL GA S :
• DO NOT try to light any appliance.
• DO NOT touch any elect ric sw itch; do not use any t elephone in your building.
• Immediately call your gas supplier from a telephone in another building. Follow the gas supplier’s
instructions.
• If y ou cannot reach your gas supplier, call t he fire department.
To comply with NSF requirements this water heater is to be:
a) Sealed to the floor with sealant, in a smooth and easily cleanable way, or

hot enough to cause scald injury. The water is under pressure and may splash.
For protection against excessive temperatures 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, ANS Z21.22 and the Standard CAN1-4.4 Temperature, Pressure, Temperature and
Pressure Relief Valves and Vacuum Relief Valves. The combination temperature and pressure relief valve must be
marked with a maximum set pressure not to exceed the maximum working pressure of the water heater. The
combination temperature and pressure relief valve must also have an hourly rated temperature steam BTU
discharge capacity not less than the hourly rating of the water heater.
Install the combination temperature and pressure relief valve into the opening provided and marked for this purpose
on the water heater.
Note: Some models may already be equipped or supplied with 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 that water discharged from the combination 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 live electrical
part. The discharge line is to be installed to allow for complete drainage of both the combination temperature and
pressure relief valve and the discharge line. 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.

DISHWASHING MACHINE RE QUIREMENTS
All dishwashing machines meeting the National Sanitation Foundation requirem ents are designed to operate with water
flow pressures between 15 and 25 pounds per square inch. Flow pressures above 25 pounds per square inch, or below 15
pounds per square inch, will result in improperly sanitized dishes.
The National Sanitation Foundation also recommends circulation of 180°F water. Where this is done, the circulation should
be very gentle so that it does not cause any unnecessary turbulence inside the water heater. The circulation should be just
enough to provide 180°F water at the point of take-off to the dishwashing machine. Adj ust flow by means of the valve in
the circulation line.
A sacrificial anode is used to ex tend tank life. The removal of this anode, ex cept for inspection and/or replacement, will
nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction
between the sacrificial anode and the impurities in the water. If this should happen, an alternative anode may be
purchased from the supplier that installed this water heater. This will minimize the odor while protecting the tank.
Additionally, the water heater should be flushed with appropriate dissolvers to eliminate any bacteria.

AIR REQUIREMENTS
1. Do not obstruct the flow of ventilating air.
2. For s afe operation, adequate air is needed for com bustion and ventilation. Sooting may result in serious damage
to the water heater and risk of fir e or ex plosion. It can also create a risk of asphyxiation. Such a condition often will
result in a yellow, luminous burner flame, causing carboning or sooting of the combustion chamber, burner and
flue tubes.
MECHANICAL EXHAUSTING OF ROOM AIR - Where an exhaust fan is installed in the same room with this
water heater and combustion air is drawn from inside the room, sufficient openings for air must be provided in the
walls. UNDERSIZED OPENINGS WILL CAUSE AIR TO BE DRAWN INTO THE ROOM THROUGH THE WATER
HEATER’S VENTING SYSTEM, CAUSING POOR COMBUSTION THAT MAY BE HAZARDOUS TO LIFE.
SOOTING MAY RESULT IN SERIOUS DAMAGE TO THE WATER HEATER AND RISK OF FIRE OR EXPLOSION,
WHICH CAN ALSO CREATE A RISK OF ASPHYXIATION. Refer to local codes and /or National Fuel Gas Code
(ANSI Z223.1-Latest Edit ion), or in Canada CAN/CGA B149 . 1 Natural Gas Installation Code (Latest Edition) or
