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 pro- vide 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, clean- ing establishments, or self-service laundries with dry cleaning equip- ment, it is imperative that the water heater or water heaters be in- stalled 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 54 for specifics provided con- cerning air required.
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 INJURY, 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 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
1.The appliance and its individual shutoff valve must be discon- nected from the gas supply piping system during any pressure 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 sys- tem 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).
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 PROPERTY DAMAGE.
WARNING
The water heater must be properly vented 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.
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
Minimum clearances between the water heater and combustible and non-combustible construction are: 0 inches from sides, 0 inch- es from back, 6 inches from front of jacket to closet door and 12 inches from top of jacket to combustible and non-combustible material. Minimum vent clearance: 0 inches. Provide 24 inches front clearance for servicing and adequate clearance between the jacket top and ceiling for servicing the flue area.
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 temperature-pressure relief valve.
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 con- trol 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 (air must get to the burner).
e.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.
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 connections should leak, the flow of water will not cause dam- age 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. Under no circum- stances is the manufacturer to be held liable for any water damage in connection with this water heater.
