GENERAL SAFETY PRECAUTIONS Safety and energy conservation are factors to be considered when setting the water temperature. The most energy efficient operation will result when the temperature setting is the lowest value that satisfies the needs consistent with the application. ! DANGER The following chart details the relationship of water temperature and time to scald injury and may be used as a guide in determining the safest water temperature for your applications.
GENERAL SAFETY PRECAUTIONS Be sure to read and understand the entire Use and Care Manual before attempting to install or operate this water heater. It may save you time and money. Pay particular attention to the Safety Instructions. Failure to follow these warnings could result in serious bodily injury or death. Should you have problems understanding the instructions in this manual, or have any questions, STOP, and get help from a qualified service technician, or the local gas utility.
GENERAL SAFETY PRECAUTIONS ! WARNING: Both LP and natural gas have an odorant added to help detection. Some people may not physically be able to smell or recognize this odorant. If unsure or unfamiliar about the smell associated with LP or natural gas, ask the gas supplier. Other conditions, such as "Odorant Fade", which causes the odorant to "fade" or diminish in intensity can also hide or camouflage a gas leak.

INSTALLATION This water heater must be installed in accordance with these instructions, local codes, utility company requirements, and/or in the absence of local codes, use the latest edition of the American National Standard/National Fuel Gas Code. A copy can be purchased from either the American Gas Association, 400 N. Capitol Street NW, Washington, DC 20001 as ANSI standard Z223.1 or National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269 as booklet NFPA 54.
INSTALLATION I f the water heater is to be installed directly on carpeting, the water heater shall be installed on a metal or wood panel extending beyond the full width and depth of the water heater by at least 3 in. (7.6 cm) in all directions or, if the water heater is to be installed in an alcove or closet, the entire floor must be covered by a wood or metal panel. thereby relieving the over pressure condition and eliminating the repeated operation of the relief valve.
INSTALLATION from the water heater and piping. A steady flow of water from the hot water faucet(s) indicates a full water heater. DO NOT allow the flammable vapor sensor to become submerged in water. To Gas Supply Manual Gas Shut Off Union GAS SUPPLY The inlet gas pressure to the water heater must not exceed 10.5" wc (2.6 kPa) for Natural gas and 13.0" wc (3.2 kPa) for L.P. gas. The minimum inlet gas pressure (with main burner on) is shown on the rating plate.
INSTALLATION CONDENSATE NEUTRALIZER Natural Gas models with sea level rated input rates of 50,000 BTUH require adjustments on touch screen display for high altitude installations above 2000ft. These adjustments are activated only on models that require high altitude adjustments Refer to vent length chart in 'Venting and Air Intake' section for appropriate elevations, vent sizes, and lengths.
INSTALLATION WIRING A correct polarity 120V 50/60 Hz power supply with suitable disconnect means, must be connected to the black and white leads provided. The maximum current draw by these models is 7 Amps. The water heater, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 in the United States, or CSA C22.1 Electrical Code, in Canada.

INSTALLATION VENT AND COMBUSTION AIR INLET NOTE: This unit can be vented either as a direct vent or power NOTICE: vent configuration. This unit can be vented using only the below recommended pipe material. Use only 2, 3, or 4 inch ! WARNING: diameter pipe. DO NOT connect this water heater to an existing vent or chimney; it must be vented separately from all other appliances, using only approved venting materials.
INSTALLATION NOTICE: Use of PVC cellular core (ASTM-F891), ABS Schedule 40, DWV cellular core (ASTM –F628), or Radel® (polyphenylsulfone) in non-metallic venting systems is prohibited. The unit may be vented horizontally through a wall or vertically through the roof. Pipe runs must be adequately supported along both vertical and horizontal runs. Maximum unsupported span is recommended to be no more than 3 feet.
INSTALLATION NOTICE: FOR PROPER INSTALLATION CAUTIONS: Cement must be fluid; if not, re-coat. 4. Hold the pipe fitting for 30 seconds to prevent the tapered socket from pushing the pipe out of the fitting. • DO NOT use solvent cement that has become curdled, lumpy or thickened. 5. Wipe all excess cement from the joint with a rag. Allow 15 minutes for drying before handling. Cure time will vary according to fit, temperature, and humidity. • DO NOT thin solvent cement.

INSTALLATION Direct Vent Installation Check to make sure flue gases DO NOT recirculate into the air intake terminal when using direct venting. If the water heater is having service issues, flue recirculation may be a contributing factor. Even when the minimum vent terminal separation distances are followed, recirculation may still occur, depending upon the location outside the building, the distance from other buildings, proximity to corners, weather conditions, wind patterns, and snow depth.
INSTALLATION TYPICAL HORIZONTAL VENT INSTALLATION Min. 24" Max. 36" in severe damage to the structure or exterior finish of the building. In locations with extended amounts of time with temperatures under 40°F. (4°C.) and/or prevailing wind toward the outlet vent, make sure that the outlet vent terminal is at least 2 feet (0.61 m) away from anything that can be damaged by the condensate.
INSTALLATION VERTICAL VENT TERMINAL LOCATION The location of the vertical vent terminal depends on the following considerations (see Vertical Vent Terminal Location Figure on previous page): 1. Minimum 12 in. (30.5 cm) above roof. Minimum 18" above roof line for Canada. 2. Minimum 12 in. (30.5 cm) above anticipated snow level. 3. Maximum 24 in. (61cm) above roof level without additional support for vent. 4. Four (4) ft. (1.
