    DRAW THEIR OWN BATH WATER. NEVER LEAVE A CHILD OR DISABLED PERSON UNATTENDED IN A BATHTUB OR SHOWER. THE WATER HEATER SHOULD BE LOCATED IN AN AREA WHERE THE GENERAL PUBLIC DOES NOT HAVE ACCESS TO SET TEMPERATURES. The water temperature is controlled using the Temperature Control Button on the Display at the front of the unit (See Figure 1).

    INSULATION BLANKETS Insulation blankets available to the general public for external use on gas water heaters are not approved for use on your water heater. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank water heaters. Your water heater meets or exceeds the ASHRAE/IES 90.1 2004 standards with respect...

  • Page 6: Hard Water

    HARD WATER Where hard water conditions exist, water softening or the threshold type of water treatment is recommended. This will protect the dishwashers, coffee urns, water heaters, water piping and other equipment. See MAINTENANCE section for details of tank cleanout procedure. AIR REQUIREMENTS KEEP APPLIANCE AREA CLEAR AND FREE OF COMBUSTIBLE MATERIALS, GASOLINE AND OTHER FLAMMABLE VAPORS AND LIQUIDS.

    TO PREVENT EXHAUSTING PRODUCTS FROM CIRCULATING TO THE AIR INTAKE IN WINDY/COLD AREAS, THE MAXIMUM PRACTICAL DISTANCE BETWEEN THESE TWO TERMINALS IS RECOMMENDED. TO PREVENT EXHAUSTING PRODUCTS FROM CIRCULATING TO THE AIR INTAKE IN WINDY/COLD AREAS, THE MAXIMUM PRACTICAL DISTANCE BETWEEN THESE TWO TERMINALS IS RECOMMENDED. U.S.
  • Page 9: Direct Venting

    IMPORTANT The vent system must terminate so that proper clearances are maintained as cited in local codes or the current editions of the National Fuel Gas Code, ANSI Z223.1/NFPA 54. Do not terminate the exhaust vent terminal over public area where condensate or vapor can cause nuisance or hazard.

    The first temperature on this screen is the temperature of the water inside the tank. The second temperature on this screen is the Operating Set Point. The Operating Set Point is the temperature at which the water heater will maintain the water inside the tank. The third line on the screen is a text description of the Operational State of the water heater (please see Operating States for more details).
  • Page 17: Operating States

    In the main desktop screen, there are some specific Operating States that are indicated on the status line. These are summarized below: 3. Adjusting the Operating Set Point The Operating Set Point of this water heater determines the regulated temperature for the water in the tank. This parameter is adjusted in the Temperature menu.

    5. Fault and Alert Conditions This water heater is equipped with electronic controls that have the ability to monitor almost all aspects of the water heater operation. In the case that there is an undesirable or unsafe condition that occurs, the water heater controls will detect this condition and determine the appropriate action.
  • Page 19: Viewing The Fault History

    PRIOR TO START UP REQUIRED ABILITY Be certain that the water heater is full of water, that air is purged from all lines, there are no leaks (gas and water), and all inlet water lines are open. The following test equipment should be on hand (all test equipment must be acclimated to ambient temperature before calibration and use.)
  • Page 20: Operating Instructions

    ADJUSTMENT PROCEDURE INITIAL START-UP Main line gas pressure to the water heater for natural gas should be between a maximum of 10.5" (2.59Kpa for natural gas) W.C. (14.0"/3.45Kpa for propane) and a minimum as shown in Table 4: that is, for Natural Gas 4"...

  • Page 30: Manifold Kits

    MANIFOLD KITS Precision cut type “L” all copper State manifold kits assure water flow balance of all units. Without this balance, the full water heating and storage potential of the system cannot be achieved. Plus, the units with the higher water flow may have a shortened life. Dimensions shown are for minimum space occupied by the water heaters assemblies.

    • Contacts click or snap as the heater starts and stops. • Transformers often hum. WATER LEAKAGE IS SUSPECTED 1. Check to see if the water heater drain valve is tightly closed. Also check the cleanout opening for leakage. 2. The apparent leakage may be condensation which forms on cool surfaces of the heater and piping.
  • Page 32: Replacement Parts

    MOTOR WILL NOT RUN 1. Confirm 120V AC to the controller. Also, to verify correct polarity, check for 120 V AC between hot supply and ground. If there is no voltage, check for a loose connection where it connects to the controller.
