1. Set the thermostat to lowest setting. 2. Turn off all electric power to appliance if service is to be performed. 3. Push in gas control knob slightly and turn clockwise to “OFF”. Do not force. FOR YOUR SAFETY READ BEFORE OPERATING 9. Set thermostat to desired setting. 10. If the appliance will not operate, follow the instructions “To Turn Off Gas To Appliance” and call your service technician or gas supplier. 22 WARNING UNDER NO CIRCUMSTANCES SHOULD THE INPUT EXCEED THE RATE SHOWN ON THE HEATER RATING PLATE. OVERFIRING COULD RESULT IN DAMAGE OR SOOTING OF THE HEATER. CATHODIC PROTECTION CAUTION HYDROGEN GAS CAN BE PRODUCED IN A HOT WATER SYSTEM SERVED BY THIS HEATER THAT HAS NOT BEEN USED FOR A LONG PERIOD OF TIME (GENERALLY TWO WEEKS OR MORE). HYDROGEN GAS IS EXTREMELY FLAMMABLE. To reduce the risk of injury under these conditions, it is recommended that a hot water faucet be opened for several minutes before using any electrical appliance connected to the hot water system. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open. PRECAUTIONS IF THE UNIT IS EXPOSED TO OR EXHIBITS THE FOLLOWING, DO NOT OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE BEEN MADE BY A QUALIFIED SERVICEMAN. 1. FLOODING TO OR ABOVE THE LEVEL OF THE BURNER OR CONTROLS 2. EXTERNAL DAMAGE 3. FIRING WITHOUT WATER 4. SOOTING NEVER OPERATE THE HEATER WITHOUT FIRST BEING CERTAIN IT IS FILLED WITH WATER AND ATEMPERATURE AND PRESSURE RELIEF VALVE IS INSTALLED IN THE RELIEF VALVE OPENING OF THE HEATER. SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL TO SHUT OFF, TURN OFF THE MANUAL GAS CONTROL VALVE TO THE APPLIANCE. GENERAL INFORMATION POWER BURNER The initial start-up procedure of the unit is provided on page 19. The sequence of operation of the unit is provided on page 16. It is important to note that the controller has a reset button on the control box, Figure 1. The reset button is a safety device and would not normally be used. HIGH LIMIT The high limit (not adjustable) is factory set to cutout at 202°F (94°C). The controller must be manually reset by depressing the reset button on front of the control when water temperature drops to below 160°F (71°C). TABLE 4. GAS SUPPLY SPECIFICATIONS Nat.

Call the local gas or utility company to verify BTU content. Due to the input rating reduction at high altitudes, the output rating of the appliance is also reduced and should be compensated for in the sizing of the equipment for applications. MAINTENANCE GENERAL KEEP APPLIANCE AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE AND OTHER FLAMMABLE VAPORS AND LIQUIDS. (SEE WARNING ON PAGE 5, LOCATING THE HEATER). Water heater maintenance includes periodic tank flushing and cleaning, and removal of lime scale. The unit should be inspected and adjusted to maintain proper combustion. Refer to the following table. A periodic inspection of the venting system should be made. Where used, the water circulating pump should be oiled. 23 MAINTENANCE SCHEDULE Following are the instructions for performing some of the recommended maintenance. Unit inspection and adjustment should be performed by a competent technician.
