INSTALLATION
!WARNING
Read and review this entire manual with special emphasis on the Venting Sections and Operation Sections prior to any installation work.
LOCAL INSTALLATION REGULATIONS
This water heater must be installed in accordance with these instructions, local codes, utility company require- ments, and/or in the absence of local codes, the latest edition of the American National Standard / National Fuel Gas Code, a copy of which can be purchased from either American Gas Association, 1515 Wilson Blvd., Arlington, VA 22209 as booklet Z223.1 or National Fire Prevention Association, 1 Batterymarch Park, Quincy, MA 02269 as booklet NFPA 54.
The water heater must be located or protected so it is not subject to physical damage, for example, by moving objects, area flooding, etc.
!CAUTION
The water heater should not be located in an area where leakage of the tank or connections will result in damage to the area adjacent to it or to lower floors of the structure. When such areas cannot be avoid- ed, it is recommended that a suitable catch pan, ade- quately drained, be installed under the water heater. The pan MUST NOT restrict the flow of combustion air flow.
NOTE: Auxiliary catch pan installation MUST con- form to the applicable local codes
LOCATION
Choose a location for your water heater centralized to the piping system, along with consideration to vent pipe length. As the length of vent pipe increases, the firing rate of the appliance decreases. You must also locate the Advantage Plus where it will not be exposed to below freezing temperatures. Additionally, you will need to place the water heater so that the controls, drain, inlet/outlet, and gas valve are easily accessed. This appliance must not be installed outdoors, as it is certified as an indoor appliance, and must be kept vertical and on a level surface. Also, care must be exercised when choosing the location of this appliance where leakage from the relief valve, leakage from related piping, or leak- age from the tank or connections, will not result in dam- age to the surrounding areas or to the lower floors of the building. A water heater should always be located in an area with a floor drain or installed in an adequate- ly drained catch pan suitable for water heaters. Proper clearance must be provided around the AdvantagePlus as follows: Sides, bottom, top, and back are 0" (zero clearance). Front of the appliance needs 24"
service clearance minimum. This front service may be achieved by a
TEMPERATURE AND PRESSURE RELIEF VALVE
A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22, must be installed in the opening provided on the water heater at the time of installation. No valve is to be placed between the relief valve and the water heater. For circulating tank installation, the sepa- rate storage tank(s) must have similar protection. The pressure rating of the relief valve must not exceed the maximum working pressure as marked on the front of the water heater. The Btu/h rating of the relief valve must equal or exceed the Btu/h input of the water heater as noted on its rating plate. Connect the outlet of the relief valve to a suitable open drain. The discharge line must pitch downward from the valve to allow complete draining (by gravity) of the relief valve and discharge line, and must be no smaller than the outlet of the relief valve. The end of the discharge line should not be threaded or con- cealed and should be protected from freezing. No valve of any type, restriction or reducer coupling should be installed in the discharge line. Local codes shall govern the installation of the relief valves.
EXPANSION TANK
A potable hot water expansion tank may be required to offset the water expansion as the water is heated. In most city plumbing systems, the water meter has a no return or back flow device built into the system to prevent back flowing of water back into city mains. Back flow pre- venters may be found on all incoming water supplies. Under these circumstances, you will need a hot water expansion tank listed for potable water use. The expan- sion tank should be located on the cold inlet piping close to the water heater. The expansion tank must be suit- able for hot potable water.
!WARNING
The manufacturer’s warranty does not cover any damage or defect caused by installation or attach- ment or use of any special attachments such as ener- gy saving devices (other than those authorized by the manufacturer) into, onto, or in conjunction with the water heater. The use of such unauthorized
