PERFORMEDONLYBYAQUALIFIEDSERVICETECHNICIAN. READ THE GENERALSAFETY 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 door(s) 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.
WARNING
Use appropriate caution when performing this inspection and do not put any part of your body immediately in front of the combustion chamber.
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
The thermostat has a single use
POWER VENTER MAINTENANCE
The water heater 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.AIR SUPPLY BOX - Every month check operation and make sure nothing is blocking dilution air entrance.
4.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.
FIGURE 11
VENTING SYSTEM | T & P VALVE |
HAVE VENTING SYSTEM CHECKED EVERY SIX MONTHS FOR OBSTRUCTIONS AND/OR DETERIORATION IN VENT PIPING.
A.Insofar as is practical, close all doors, windows and air inlets to the building. Turn on all exhaust fans (range hood, bathroom exhaust, etc.) so they will operate at their maximum speed. Close fireplace dampers.
B.Turn water temperature adjusting knob to full, counterclockwise and open water faucet if necessary to keep burner in operation.
C.“CHECKING THE DRAFT.” Operate the water heater for several minutes and check to see if it is venting properly by passing a lit match or paper near the opening of the Air Mixing Box (See figure 11). If the draft is proper, the match flame will be drawn into the Air Mixing Box. If not, the combustion products will tend to extinguish the flame. If an improper draft exists, do not operate the water heater until proper adjustments or repairs are made to provide adequate draft through the gas vent.
D.Next, turn on all other fuel burning appliances within the same room so they will operate at their full input.
Repeat step C above.
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.
