SAFETY PRECAUTIONS (cont.)

WARNING: Gasoline, as well

as other flammable materials and liquids (adhesives, solvents, paint thinners, etc.) and the vapors they produce, are extremely dangerous. DO NOT handle, use or store gasoline or other flammable or combustible materials anywhere near or in the vicinity of a water heater or any other appliance. Be sure to read and follow the labels on the water heater, as well as the warnings printed in this manual. Failure to do so can result in property damage, bodily injury or death.

WARNING: Do not use substitute

materials. Use only parts certified with the appliance.

• This appliance must be installed, inspected and leak tested by a state- and city-qualified licensed contractor. It is the responsibility of the person having the water heater installed to ensure the installing contractor has proper licenses and permits for installing water heaters in your location. GE highly recommends that installers attend a product knowledge class to ensure customer satisfaction and warranty coverage. Failure to comply with state and local codes pertaining to water heater installations may void the warranty.

• This appliance is not to be installed indoors.

• The installation must conform with local codes or, in the absence of local codes, with the National

Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1.

• The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa) (13.84 in W.C.).

SAFETY PRECAUTIONS (cont.)

• The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa) (13.84 in W.C.).

• The appliance should be located in an area where water leakage of the unit or connections will not result in damage to the area adjacent to the appliance or lower floors of the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. The pan must not restrict combustion airflow.

• The flow of combustion and ventilation air shall not be obstructed.

• This appliance is not suitable for use in an application such as a pool or spa heater that uses chemically treated water. (This appliance is suitable for filling large or whirlpool bath tubs with potable water.)

• If a water heater is installed in a closed-water supply system, such as one having a backflow preventer in the cold water supply line, means shall be provided to control thermal expansion. Contact the water supplier or local plumbing inspector on how to control this situation.

• Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.

• Keep the air intake location free of chemicals, such as chlorine or bleach, that produce fumes. These fumes can damage components and reduce the life of your appliance.

CAUTION:DO NOT operate the water

heater if any part of the appliance has been under water.

CAUTION:BURN HAZARD. Hot exhaust

and vent may cause serious burns. Keep back from water heater unit. Keep small children and animals away from unit .

CAUTION:Hot Water outlet pipes leaving

unit can be hot to touch. Insulation must be used for hot water pipes below 36″ due to burn risk to children.

WARNING: This unit is not intended

or qualified for use in manufactured homes, mobile homes or recreational vehicles.

MOUNTING THE WATER HEATER (cont.)

dentify the installation location and confirm

that the installation will meet all required clearances. Use mounting template to locate screw or anchor locations.

Securely attach the water heater to the wall

using the brackets located at the top and bottom of the water heater.

Ensure that the attachment strength

is sufficient to support the weight. Refer to the weight of the water heater in the Specification Guidelines. Four mounting screws with 200 lb tensile load capacity are required at a minimum.

Wall installation brackets

ON WOOD OR SIDING: When attaching

the unit to wood or siding, mount 2 boards suitable for anchoring to wall studs, between the studs. You can do this before the wall has been finished.

NOTE: Do not hang the unit on wood or siding only. The unit must be secured to studs.

CORROSIVE ATMOSPHERES

NOTICE: The water heater or intake air supply should not be installed near an air supply containing halogenated hydrocarbons or near swimming pool chemicals.

MOUNTING THE WATER HEATER

CAUTION: Reinforcement of the

wall is required in case the wall is not strong enough to hold the water heater. Do not mount to drywall unless mounting screws are secured in wall studs.

Make sure the location of the water heater allows for easy access and operation.

Wall studs should be utilized when mounting the water heater to the wall. On masonry or concrete wall, use concrete anchors or lag bolts.
