    The temperature may be adjusted from 80°F/27°C to 180°F/82°C. The thermostat was adjusted to 120°F/49°C before the heater was shipped from the factory. It is recommended that lower water temperatures be used to avoid the risk of scalding. It is further recommended, in all cases, that the water temperature be set for the lowest temperature which satisfies your hot water needs.

  • Page 6: Circulating Pump

    CIRCULATING PUMP A circulating pump is used when a system requires a circulating loop or there is a storage tank used in conjunction with the heater. Refer to the piping diagrams at rear of manual for electrical hookup information and install in accordance with the current edition of the National Electrical Code, NFPA 70 or the Canadian Electrical Code, CSA C22..

  • Page 7: Clearances

    CLEARANCES These heaters are approved for installation on combustible flooring in an alcove when the minimum clearances from any combustion construction are followed as indicated in Figure 4. In all installations the minimum combustible clearances from any vent piping shall be 0". Vent piping passing through a combustible wall or ceiling must be a continuous run (no joints).

    WARNING NEVER OPERATE THE HEATER UNLESS IT IS VENTED TO THE OUTDOORS AND HAS ADEQUATE AIR SUPPLY TO AVOID RISKS OF IMPROPER OPERATION, FIRE, EXPLOSION OR ASPHYXIATION. VENT PIPE TERMINATION NOTE: Before installing venting, determine place of vent pipe termination. See Figure 5 and 6 before proceeding. CAUTION DO NOT TERMINATE THE VENTING WHERE NOISE FROM THE EXHAUST OR INTAKE WILL BE OBJECTIONABLE.

    2. Drill a pilot hole approximately 1/4" (6 mm) outside of the marked circle. This pilot hole is used as a starting point for a saws- all or sabre saw blade. Cut around the marked circle staying approximately one quarter inch outside the line. (This will allow the vent pipe to easily slide through the opening).

  • Page 14: Vent Pipe Preparation

    WELL-VENTILATED AREA. CONTROLS AND SWITCHES The SUF-130-300 and 400 are equipped with four pressure switches. These switches are essential to the safe and proper operation of the unit. All switches are wired in series. The controller is set up to shut the unit down whenever there is a failure of any of the switches.

    CAUTION THE WATER HEATER IS POLARITY SENSITIVE. BEFORE APPLYING ELECTRICITY TO THIS HEATER BE CERTAIN THAT SUPPLY NEUTRAL WIRE TO GROUND CHECK INDICATES ZERO VOLTAGE. HOT SURFACE IGNITER The Hot Surface Igniter is a device that ignites the main burner by high temperature (>1800°F or >982°C).

  • Page 16: Purging

    To prevent damage, care must be taken not to apply too much torque when attaching gas supply pipe to gas valve inlet. Apply joint compounds (pipe dope) sparingly and only to the male threads of pipe joints. Do not apply compound to the first two threads. Use compounds resistant to the action of liquefied petroleum gases.

  • Page 20: Sequence Of Operation

    OPERATION SEQUENCE OF OPERATION Typical Control/Appliance Operating Sequence When the control is powered, it should display the unit model, water temperature, setting temperature and heater status. If the control determines that the actual water temperature inside the tank is below the programmed temperature setpoint less the differential, a call for heat is activated.

  • Page 21: Adjusting The Operating Set Point

    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. Items in this menu allow you to monitor different temperature readings in the tank along with adjusting the Operating Set Point and Differential.

  • Page 22: Changing The Display Units

    4. Changing the Display Units The display interface to the heater has the option of selecting between degrees and Fahrenheit and degrees Celsius for temperature displays. This can be found in the "Display Settings" menu. Also in this menu, you may adjust how the backlight operates and the contrast of the LCD screen.

  • Page 23: Access To The Current Fault Or Warning

    • Faults: This is a safety related condition that has been detected by the heater. NOTE: When these conditions occur, the water heater will not continue any further heating cycles and the water will no longer be heated until the condition is corrected and, in most cases, power has been cycled. Example of a Fault: Advanced Diagnostics Information When a fault or warning has been declared, advanced information can be found in the control.

  • Page 24: Viewing The Fault History

    7. Viewing the Fault History The controller for this water heater will store a history of ten of the last Fault and Warning conditions that occurred. This is stored in the Fault History. Along with all the information about the fault, including a estimate time of when the fault occurred, information regarding the advanced diagnostics for that fault can be accessed at any time.

  • Page 25: Prior To Start-Up Required Ability

    PRIOR TO START UP - REQUIRED ABILITY INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK ARE REQUIRED. Before attempting start-up, thoroughly study and familiarize yourself with the exact sequence of operation and all other details on the specific heater being used.

  • Page 35: Multiple Unit Installations

    MULTIPLE UNIT INSTALLATIONS Proper installation of multiple water heaters assures 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.

  • Page 36: Checklist And Service Information

    CHECKLIST AND SERVICE INFORMATION IMPORTANT The installer may be able to observe and correct certain problems which might arise when the unit is put into operation or when it is re-fired after a prolonged shutdown. HOWEVER, it is recommended that only qualified servicemen, using appropriate test equipment, be allowed to service the heater.
