• Electrical control box includes starters for each heater/pump section.
• Include a service-rated electrical disconnect switch, eliminating the need to add a second service-rated disconnect switch as required by the National Electrical Code.
• Indicator light to alert operator that the low water flow limit switch has shut down the burner due to inadequate water flow.
• The temperature control switch and the manual reset high temperature limit switch water heater shut off burner in case of excessive water discharge temperature.
• ASME-rated pressure relief valve opens to discharge water in case of excessive buildup.
• Pressure gauges and bi-metal thermometers on both inlet and outlet allow monitoring of differences between incoming and outgoing water temperature and pressure. Y-strainer on water inlet ensures foreign particles do not enter heater water supply.
