INSTALLED IN SUITABLE AREA: To insure sufficient ventilation andcombustion air supply, proper clearances from the water heater mustbe maintained. See “Locating the New Water Heater” section.Combustible materials such as clothing, cleaning materials, or flammableliquids, etc. must not be placed against or adjacent to the water heaterwhich can cause a fire.ANODE ROD INSPECTIONIf the temperature-pressure relief valve on the appliance weeps ordischarges periodically, this may be due to thermal expansion. Youmay have a check valve installed in the water line or a water meterwith a check valve. Consult your local water supplier or serviceagency for further information. Do not plug the temperature-pressurerelief valve.DRAININGThe anode rod is used to protect the tank from corrosion. Most hotwater tanks are equipped with an anode rod. The submerged rodsacrifices itself to protect the tank. Instead of corroding the tank,water ions attack and eat away the anode rod. This does not affectthe water’s taste or color. The rod must be maintained to keep the tankin operating condition.Anode deterioration depends on water conductivity, not necessarilywater condition. A corroded or pitted anode rod indicates high waterconductivity and should be checked and/or replaced more often thanan anode rod that appears to be intact. Replacement of a depletedanode rod can extend the life of your water heater. Inspection shouldbe conducted by a qualified technician, and at a minimum should bechecked annually after the warranty period.TEMPERATURE-PRESSURERELIEF VALVE OPERATIONThe water heater should be drained if being shut down during freezingtemperatures. Also periodic draining and cleaning of sediment fromthe tank may be necessary.1. Turn the gas control knob to the “OFF” position.2. CLOSE the cold water inlet valve to the water heater.3. OPEN a nearby hot water faucet and leave open to allow fordraining.4. Connect a hose to the drain valve and terminate to an adequatedrain.5. OPEN the water heater drain valve to allow for tank draining.NOTE: If the water heater is going to be shut down anddrained for an extended period, the drain valve should beleft open with hose connected allowing water to terminateto an adequate drain.6. CLOSE the drain valve.7. Follow instructions in the “Filling The Water Heater” section.8. Follow the lighting instructions on the label or the “Lighting andOperating Instructions” section to restart the water heater.DRAIN VALVE WASHER REPLACEMENT FORSELECTED MODELS WITH PLASTIC DRAIN VALVES(See Figure 19)The temperature-pressure relief valve must be manually operated atleast once a year.When checking the temperature-pressure relief valve operation, makesure that (1) no one is in front of or around the outlet of the temperaturepressurerelief valve discharge line, and (2) that the water dischargewill not cause any property damage, as the water may be extremelyhot, see Figure 18.1. Turn “OFF” gas supply to water heater.2. Follow “Draining” instructions.3. Turning counterclockwise ( ), remove the hex cap below thescrew handle.4. Remove the was her and put the new one in place.5. Screw the handle and cap assembly back into the drain valve andretighten using a wrench. DO NOT OVER TIGHTEN.6. Follow instructions in the “Filling The Water Heater” section.7. Check for leaks.8. Follow the lighting Instructions in the “Lighting and OperatingInstructions” section to restart the water heater.FIGURE 18.If after manually operating the valve, it fails to completely reset andcontinues to release water, immediately close the cold water inlet tothe water heater, follow the draining instructions, and replace thetemperature-pressure relief valve with a new one.20FIGURE 19.
