Preventive Maintenance

BLOWER MAINTENANCE

For safety and satisfactory operation it is recommended that the blower be checked once a year by a competent service person.

1.MOTOR - The motor is factory oiled and sealed and requires no further maintenance.

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.

3.The pressure switch is inside the blower control box and is connected to the blower housing with a tube. This tubing should be soft and pliable and show no sign of deterioration.

RELIEF VALVE

At least once a year the temperature and pressure relief valve should be checked to ensure that it is in operating condition. (During manual operation of this valve, avoid any contact with hot water and take preventive steps for water damage). 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.

If the temperature and pressure relief valve on the heater discharges periodically or continuously, a problem exists. This may be due to unusually high water temperatures or pressures in the system, or to a faulty relief valve. Contact your dealer or a qualified service technician to find the cause of the problem and to correct it. This may also be due to thermal expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on how to correct this situation. DO NOT PLUG THE TEMPERATURE AND PRESSURE RELIEF VALVE.

WARNING

SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL TO SHUT OFF, TURN OFF THE MANUAL GAS CONTROL VALVE TO THE APPLIANCE.

HOT WATER ODOR

On occasion, hot water may develop a strong odor. If this occurs drain the heater completely, flush thoroughly, and refill. If the problem persists, chlorination of the heater and replacement of the factory installed magnesium anode with aluminum anode may correct the condition.

Occasionally water softener companies recommend removal of heater anodes for odor reasons.

CAUTION

Unauthorized removal of heater anode will void the warranty. Replace the anode as necessary to maintain corrosion protection. For further information contact your dealer.

WINTER PROTECTION

In regions where freezing weather is encountered, all water must be drained from unit and piping when out of service (water shut off). Drain valve must be left open until unit is returned to service.

RECOMMENDED PROCEDURE FOR PERIODIC REMOVAL OF LIME DEPOSITS FROM TANK TYPE COMMERCIAL WATER HEATERS

FIGURE8

The amount of calcium carbonate (lime) released from water is in direct proportion to water temperature and usage, see chart. The higher the water temperature or water usage, the more lime deposits are dropped out of the water. This is the lime scale which forms in pipes, heaters and on cooking utensils.

Lime accumulation not only reduces the life of the equipment but also reduces efficiency of the heater and increases fuel consumption.

The usage of water softening equipment greatly reduces the hardness of the water. However, this equipment does not always remove all of the hardness (lime). For this reason it is recommended that a regular schedule for deliming be maintained.

The time between cleaning will vary from weeks to months depending upon water conditions and usage.

Refer to A. O. Smith booklet, Form No. 4800, entitled “Why? When and How” for detailed description on tank inspection and cleanout.

UN•LIME® and the booklet may be obtained through your A. O. Smith dealer or distributor.

DELIMING SOLVENTS

A. O. Smith recommends the use of UN•LIME for deliming. UN•LIME is a patented food grade acid which is safe to handle and does not create the harmful fumes which are associated with other products.

UN•LIME may be obtained from your dealer, distributor or the A. O. Smith Product Service Division. Order part no. 4763 (1 gal), packed 4 gallons per case or part no. 4813 (5 gallon container).

Hydrochloric base acids are not recommended for use on glass-lined tanks.

CAUTION

Observe handling instructions on label of product being used.
