Water is too hot from the Reliance water heater (scalding at taps).

Safety first: Risk of scalding. Warn household members and consider temporarily lowering the temperature at mixing valves. For electric units, turn OFF power before opening panels; for gas units, set the control to PILOT or OFF.

Steps to check:

• 1. Check set temperature: For electric models, remove the access panels and read the dial setting on the upper and lower thermostats. For gas models, check the temperature dial on the gas control. Adjust the setting to about 120°F.
• 2. Monitor temperature: After adjustment, allow several hours and then measure the hot water temperature at a faucet with a thermometer. If still excessively hot, suspect a faulty thermostat.
• 3. Replace thermostat (electric): With power OFF, label and remove wires from the suspect thermostat, then install a new Reliance-compatible thermostat. Set the new thermostat to 120°F.
• 4. Replace gas control (gas): If the gas control does not respond to temperature changes or overshoots, the entire gas control valve/thermostat assembly must be replaced.
• 5. Consider mixing valve: Install or service a thermostatic mixing valve at the heater outlet to provide stable, safe delivery temperatures.

Warning: Children and the elderly are especially vulnerable to scalding. Address over-temperature issues promptly.
