INPUT CHECK TIME REQUIRED TO

CONSUME 1 CU. FT. OF GAS

	Type of	BTU Per	Approx. Time Required To
Model	Gas	Cu. Ft.	Consume 1 Cu. Ft. of Gas
BT-80	Natural	1050	50.3 sec.
	Propane	2500	119.8 sec.
BT-100	Natural	1050	50.3 sec.
	Propane	2500	119.8 sec.

Use this formula to “clock” the meter. Be sure that other gas consuming appliances are not operating during this interval.

3,600 X H = Btu/Hr

T= Time in seconds needed to burn one cubic foot of gas. H = Heating value of gas in Btu’s per cubic foot of gas. Btu/Hr = Actual heater input rate.

Example: (Using BT-80 heater) T = 50.3 seconds/ft3

H= 1,050 Btu/ft3 (natural gas) Btu/Hr = ?

3,600 X 1,050 = 75,100 Btu/Hr (22.0 kW)

50.3

Compare the actual input rate to that given on the heater’s rating plate. In the example, the BT-80’s full input rate should be 75,100 Btu/Hr for natural gas.

VENT SYSTEM

Examine the venting system every 6 months for obstructions and/ or deterioration of vent piping.

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 anodes with aluminum anodes may correct the condition.

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

CAUTION

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

ANODE ROD INSPECTION

The heater tank is equipped with anode rods to provide corrosion control. At least once a year the anode rods should be checked to determine if replacement is necessary. Initially the anode rods are approximately 7/8" (22mm) in diameter with a 1/8" (3mm) diameter steel core wire running down the center of the anode material. THE ANODES SHOULD BE REPLACED when the 1/8" (3mm) diameter core wire is visible as this means that the anode material has been expended in the control of corrosion.

NOTE: Anode rod inspection may need to be made more frequently in areas subject to acid rain that obtains their water supply from surface water as the low pH will accelerate anode activity.

CAUTION: Close cold water inlet valve serving heater and open nearby hot water faucet to relieve the pressure in the heater before attempting to remove anode(s) for inspection.

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.
