Cone Proper burner and pilot flame pattern. ! CAUTION: Cone is used only on natural gas burner assemblies. Venting System Inspection The water heater's internal flue must be inspected annually to be certain it is clean by removing the venting system and flue baffle. Inspect the gas venting system and the chimney. Make certain the vent system, vent, and air pipes is properly sealed and securely attached. If after inspection of the vent system you found sooting or deterioration call the local gas utility to correct the problem and clean or replace the flue and venting before resuming operation of the water heater. Burner Inspection Visually inspect the pilot and main burners annually. Through the sight glass, inspect the pilot burner flame with the main burner off and inspect the main burner while firing. If any unusual burner operation is noted, the water heater should be shut off until qualified service assistance can be obtained. ! CAUTION: For your safety, cleaning of the burner must be performed only by qualified service personnel. The burner chamber is a sealed area. If the burner access door is removed, the burner access door gasket must be replaced. For cleaning, remove the burner from the water heater. A vacuum cleaner can be used on the burner and floor shield inside the water heater. The burner can also be cleaned by scrubbing with mild detergent. NOTICE: Refer to the Hydrogen Gas Caution in the Operating Instructions. Vacation and Extended Shut-Down If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be turned off to conserve energy and prevent a build-up of dangerous hydrogen gas. The water heater and piping should be drained if they might be subjected to freezing temperatures. After a long shut-down period, the water heater's operation and controls should be checked by qualified service personnel. Make certain the water heater is completely filled again before placing it in operation. NOTICE: Do not remove the anode rod from the water heater's tank, except for inspection and/or replacement, as operation with the anode rod removed will greatly shorten the life of the glass lined tank and will exclude warranty coverage. Anode Rod This water heater is equipped with an anode rod designed to prolong the life of the glass lined tank. The anode rod is slowly consumed, thereby eliminating or minimizing corrosion of the glass-lined tank. Water sometimes contains a high sulfate and/or mineral content and together with cathodic protection process can produce a hydrogen sulfide, or rotten egg odor in the heated water. Chlorination of the water supply should minimize the problem. 19
