IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING ! DANGER! WATER TEMPERATURE SETTING Safety and energy conservation are factors to be considered when selecting the water temperature setting of a water heater’s gas control. Water temperatures above 125°F can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined on the label pictured below. This label is also located on the water heater.

IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING ! DANGER! LIQUEFIED PETROLEUM (LP) AND NATURAL GAS MODELS LP and Natural gas have an odorant added to aid in detecting a gas leak. Some people may not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions, such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide or camouflage a gas leak.

IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING ! WARNING! For your safety, the information in this manual must be followed to minimize the risk of fire or explosion, electric shock, or to prevent property damage, personal injury, or loss of life. FOR INSTALLATIONS IN THE STATE OF CALIFORNIA California Law requires that residential water heaters must be braced, anchored or strapped to resist falling or horizontal displacement due to earthquake motions.

Installing the water heater 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.

Installing the water heater Inspect Shipment Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the type of gas supplied corresponds to the water heater requirements. Combustion and Ventilation Air Proper operation of the water heater requires air for combustion and ventilation. Provisions for combustion and ventilation air must comply with referenced codes and standards.
PAGE 9
Thermal Expansion Determine if a check valve exists in the inlet water line. Check with your local water utility company. It may have been installed in the cold water line as a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener. A check valve located in the cold water inlet line can cause what is referred to as a “closed water system”. A cold water inlet line with no check valve or back flow prevention device is referred to as an “open” water system.
PAGE 10
Installing the water heater A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22, is supplied and must remain in the opening provided and marked for the purpose on the water heater. No valve of any type should be installed between the relief valve and the tank. Local codes shall govern the installation of relief valves.
PAGE 11
WARNING: DO NOT attempt to convert this water heater for use with a different type of gas other than the type shown on the rating plate. Such conversion could result in hazardous operating conditions. Gas Supply The branch gas supply line to the water heater should be clean 1/2” black steel pipe or other approved gas piping material. A ground joint union or ANSI design certified semi-rigid or flexible gas appliance connector should be installed in the gas line close to the water heater.
PAGE 12
Installing the water heater Insulation Blankets WARNING: If local codes require external application of insulation blanket kits the manufacturer’s instructions included with the kit must be carefully followed. Insulation blankets, available to the general public, for external use on gas water heaters are not necessary. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters.

Hot and Cold Pipe Insulation Installation Typical vertical piping arrangement Typical horizontal piping arrangement For increased energy efficiency, some water heaters have been supplied with two 24” sections of pipe insulation. Please install the insulation, according to the illustrations above, that best meets your requirements. T&P Insulation Installation For increased energy efficiency, this water heater has been supplied with a 2 3/8” Typical Side Connect T & P Arrangement.

Installing the water heater During Installation of this water heater........... DO ❑ DO check inlet gas pressure to ensure that it is within the range specified on the rating plate. ❑ DON’T block or restrict Combustion Air Inlet Openings located around the lower portion of the water heater jacket. ❑ DO provide adequate air for combustion and ventilation as discussed in the Use and Care Manual and the National Fuel Gas Code. ❑ DON’T remove the Burner Access Door unless absolutely necessary.
PAGE 15
Installation Checklist A. Water Heater Location ❑ Close to area of vent. ❑ Indoors and protected from freezing temperatures. ❑ Proper clearance from combustible surfaces observed and water heater not installed on carpeted floor. ❑ Sufficient fresh air supply for proper operation of water heater. ❑ Provisions made to protect area from water damage. ❑ Sufficient room to service heater. ❑ Combustible materials, such as clothing, cleaning materials, rags, etc. clear of the base of the heater.

Operating the water heater CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system.
PAGE 19
Water Temperature Setting Maximum water temperatures occur just after the burner has shut off. To determine the water temperature, turn on a hot water faucet and place a thermometer in the water stream. The reference mark p on the rim of the temperature dial, represents an approximate water temperature of 120°F(49° C). The reference mark A represents an approximate water temperature of 130°F (54° C). Each reference mark above or below these points indicates an approximate change of 10°F.

Care and cleaning of the water heater Draining the Water Heater ! CAUTION: Shut off gas to the water heater at the gas control (thermostat) gas cock or manual shut-off valve before draining water. ! DANGER: Before manually operating the temperature and pressure relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage.
PAGE 21
Venting System Inspection The water heater’s internal flue must be inspected annually to be certain it is clean by removing the draft hood and flue baffle. When reinstalling the flue baffle make certain it is hung securely by its hanger at the top of the flue way. Reinstall the draft hood. Inspect the gas venting system and the chimney. Make certain the vent connector from the draft hood to the chimney is properly positioned and securely attached.
