Water heater installation Water Line Connections T&P Valve Discharge Pipe The water piping installation must conform to these instructions and to all local code authority having jurisdiction. Good practice requires that all heavy piping be supported. Read and observe all requirements in the following sections before installation of the water piping begins: 1. Water Temperature Control and Mixing Valves on page 12. 2. Dishwashing Machines on page 13. 3. Temperature-Pressure Relief Valve on page 13.
TEMPERATURE SETTING SHOULD NOT EXCEED SAFE USE TEMPERATURE AT FIXTURES. SEE WATER TEMPERATURE CONTROL AND MIXING VALVES ON PAGE 12. IF HIGHER PREHEAT TEMPERATURES ARE NECESSARY TO OBTAIN ADEQUATE BOOSTER OUTPUT, ADD AN ANTI-SCALD VALVE FOR HOT WATER SUPPLIED TO FIXTURES. Installation Diagrams - Top Inlet/Outlet Usage Use of the top inlet water connection requires an inlet dip tube (refer to figure 19). The tube is supplied in the heater. Follow caution labels if applying heat to this fitting.
Heater Wiring All electrical work must be installed in accordance with the latest version of the National Electrical Code ANSI/NFPA No. 70 and must conform to all local code authority having jurisdiction. AN ELECTRICAL GROUND IS REQUIRED TO REDUCE RISK OF ELECTRICAL SHOCK OR POSSIBLE ELECTROCUTION. The controls of this water heater are polarity sensitive. Be certain to properly wire the hot and neutral connections.
Supply Gas Regulator Gas Piping The minimum gas supply pressure must not be less than 3.5" w.c. (0.87 kPa). Contact your local gas service company to ensure that adequate gas service is available and to review applicable installation codes for your area. Do not subject the gas valve to inlet gas pressures of more than 14.0” W.C. (3.48 kPa). A supply gas regulator is necessary if higher gas pressures are encountered. See Gas Pressure Requirements and Supply Gas Regulator sections on page 12.
Start up Prior to Start Up Initial Start Up Installation and start up of this water heater requires abilities and skills equivalent to that of a licensed tradesman in the field involved, see Qualifications on page 6. Required Test Equipment U-tube manometer, pressure gauge, or digital manometer. Recommended range: 20” W.C. (5 kPa). Note: All test equipment must be acclimated to ambient temperature before calibration and use. Preparation 1. Adjust the thermostat to the lowest temperature setting. 2.
Supply gas pressure shall be measured while the water heater is not firing (static pressure) and while the water heater is firing at full capacity (dynamic pressure). 7. If improper venting is observed during any of the above tests, the venting system must be corrected. FAILURE TO CORRECT BACK DRAFTS MAY CAUSE AIR CONTAMINATION AND UNSAFE CONDITIONS.
Sequence of Operation The following information will describe the Sequence of Operation for this water heater. 8. If the Flame Sensor does not detect a strong enough flame, the Ignition Control shuts off the Gas Valve and allows the Blower to purge the unit for 30 seconds. At that time, the Ignition Control restarts with step 6. It will try and ignite the main burners 2 more times. If the unit does not light, the Ignition Control will wait 15 minutes and then restart at step 6.
Sequence of Operation Flow Chart Description of this flow chart can be found in the “SEQUENCE OF OPERATION” section found on page 26.
Maintenance Expansion on page 13. The Temperature-Pressure Relief Valve is not intended for the constant relief of thermal expansion. Temperature-Pressure Relief Valve leakage due to pressure build up in a closed system that does not have a thermal expansion tank installed is not covered under the limited warranty. Thermal expansion tanks must be installed on all closed water systems. DO NOT PLUG THE TEMPERATURE-PRESSURE RELIEF VALVE OPENING. THIS CAN CAUSE PROPERTY DAMAGE, SERIOUS INJURY OR DEATH.
Draining and Flushing Periodic Removal of Lime Deposits from Tank Type Commercial Water Heaters 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. Burn harzard. Hot water discharge.
