SERVICE SHOULD BE PERFORMED ONLY BY A QUALIFIED SERVICE TECHNICIAN. READ THE GENERAL SAFETY INFORMATION SECTION FIRST.
USERS OF THIS APPLIANCE SHOULD BE AWARE THAT GAS COMPONENTS WEAR OUT OVER A PERIOD OF TIME. THE GAS CARRYING COMPONENTS OF THIS APPLIANCE SHOULD BE INSPECTED FOR PROPER OPERATION PERIODICALLY BY A QUALIFIED SERVICE TECHNICIAN.
MAIN BURNER
Check main burner every 12 months for proper flame characteristics. This is done by removing the outer door on heater, Fig. 1. The main burner should provide complete combustion of gas; ignite rapidly; give reasonably quiet operation; cause no excessive flame lifting from burner ports. Make sure that the flow of combustion and ventilation air is not blocked.
If proper flame characteristics are not evident, check for accumulation of lint or other foreign material that restricts or blocks the air openings in the heater or burner. Also check AIR REQUIREMENTS.
WARNING
SOOT
Should the main burner or burner air openings require cleaning, turn the control switch to “OFF” position and allow the burner to cool. Remove the burner and clean with a soft brush. Clean main burner orifice with a suitable soft material.
HIGH TEMPERATURE LIMIT SWITCH
(Auto Reset Type Energy
TO RESET AUTOMATIC GAS SHUTOFF
This water heater is equipped with an automatic reset type high limit (Energy Cutoff) sensor. The high limit switch interrupts the main burner gas flow should the water temperature reach 205°F (96°C). The high limit will automatically reset when the water temperature drops below 140°F (60°C). After cooling the tank temperature, turn off the water heater for at least 10 seconds by using the switch on top of the unit. Turn on the water heater. If this fails to correct the problem, contact your plumber or service representative.
POWER VENTER MAINTENANCE
The unit must be inspected quarterly. Points of inspection are:
1.MOTOR - Motor must rotate freely. This is a sealed motor and no oiling is required.
2.WHEEL - Wheel must be clean of soot, ash or any other coating which inhibits either rotation or air flow. Remove all foreign material from vent system before operating.
3.The pressure switch part inside the power venter must be open and free from deposits of soot, carbon, etc.
For safety and satisfactory operation it is recommended that the heater be checked once a year by a competent service person.
T & P VALVE
At least once a year, the temperature and pressure relief valve must be checked to ensure that it is in operating condition. Lift the lever at the top of the valve several times until the valve seats properly and operates freely.
WARNING
THE WATER PASSING OUT OF THE VALVE DURING THIS CHECKING OPERATION MAY BE EXTREMELY HOT. AVOID CONTACT AND DISCHARGE SAFELY TO PREVENT WATER DAMAGE.
DRAINING
Periodically open the drain valve and allow the water to run until it flows clean. This will help prevent sediment
It is normal for lime and scale deposits to form within the tank and on the heat exchanger surfaces. Such deposits will not be removed by periodic draining. It is necessary to chemically delime the affected parts in water areas where such deposits are encountered. Contact your dealer or plumber for deliming information.
If the heater is to be shut off and exposed to freezing temperatures, it must be drained. Water, if left in the tank and allowed to freeze, will damage the heater.
•Turn off the gas and cold water inlet valve to the heater.
•Open a nearby hot water faucet and the heater drain valve.
•BE CAREFUL TO GRASP THE DRAIN VALVE HANDLE SO THAT THE HAND IS NOT EXPOSED TO HOT WATER. IF DESIRED, A HOSE MAY BE CONNECTED TO THE DRAIN VALVE TO CARRY THE WATER AWAY.
WARNING: The water CAN BE HOT.
The drain valve must be left open during the shutdown period.
• To restart heater, refer to the instructions under OPERATION.
CONDENSATE INSIDE TANK ASSEMBLY
Water vapor can condense on the cooler surfaces of the tank forming droplets, these drip into the fire or run out on the floor. This is common at the time of startup after installation, during periods of time when incoming water is very cold, or the heater may be undersized for the requirements.
Droplets from the bottom of the flue may be due to corrosive combustion products or improper vent. Check with your dealer for more information.
CATHODIC PROTECTION-ANODE
The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This does not affect the water’s taste or color. The rod must be maintained to keep the tank in operating condition.
