General Safety (cont’d)
WARNING
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
Do not install in a confined area such as 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.
WARNING
If this water heater will be used in beauty shops, barber shops, cleaning establishments, or
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 venting system can result in asphyxiation, a fire or explosion and can cause DEATH, SERIOUS BODILY IN-
JURY, OR PROPERTY DAMAGE.
WARNING
No vent damper installation is compatible with this power vented water heater design. No vent damper, whether it is operated ther- mally or otherwise is to be installed on this power vented water heater. Alteration of any part of the
WARNING
1.The appliance and its individual shutoff valve must be dis- connected from the gas supply piping system during any pres- sure testing of the gas system at test pressures in excess of 1⁄2 pound per square inch (3.5kPa).
2.The appliance must be isolated from the gas supply piping system by closing 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).

RIOUS BODILY INJURY, OR PROPERTY DAMAGE.
WARNING
The water heater must be properly vented outdoors. Never op- erate the water heater unless it is vented to the outdoors and has adequate air supply to avoid risks of improper operation, ex- plosion or asphyxiation.
WARNING
Vent termination must not be within 4 feet of any items such as gas meters, gas valves or other gas regulating equipment.
WARNING
Obstructed or deteriorated vent systems may present a serious health risk or asphyxiation.
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, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chlo- ride, waxes, bleach, and process chemicals are typical compounds which are potentially corrosive.
WARNING
Minimum clearances between the water heater and combustible and
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 condi- tions, 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 dish- washer 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.
WARNING
INSULATING JACKETS: When installing an external water heater insulation jacket on a gas water heater:
a.DO NOT cover the
b.DO NOT put insulation over any part of the top of the gas water heater.
c.DO NOT put insulation over the gas control valve or gas control valve/burner cover, or any access areas to the burner.
d.DO NOT let insulation around the gas water heater to get with- in 8 inches of the floor (access for servicing the burner).
e.DO NOT remove operating instructions, and safety related warn- ing labels and materials affixed to the water heater. DO obtain new warning and instruction labels from the manufacturer for placement on the jacket directly over the existing labels.
Failure to heed this will result in the possibility of a fire or explosion.
WARNING
Flood damage to a water heater may not be readily visible or imme- diately 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. Call a qual- ified service technician or contractor to replace a flooded water heater. Do not attempt to repair the unit! It must be replaced!
CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connec- tions 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 for access to the outer doors for servicing the ignitor and burner.
