Stacking

Stacking occurs when a series of short draws of hot water are taken from the water heater tank. This causes increased cycling of the burner and can result in increased water temperatures at the hot water outlet. A tempering valve should be installed in the hot water supply line to reduce the risk of scald injury.

Water Temperature Regulation

Water temperature over 125°F can cause severe burns instantly or death from scalds.

Children, disabled and elderly are at highest risk of being scalded.

Feel water before bathing or showering. Temperature limiting valves are recommended.

The thermostat is adjusted to its lowest temperature setting when it is shipped from the factory. Water tem- perature can be regulated by moving the temperature dial to the preferred setting. The preferred starting point is 120°F(49°C).

Important: Since most commercial installations utilize higher temperatures, the use of a tempering valve is strongly recommended in all domestic hot water lines (i.e. public restroom sinks, etc). Auxiliary commercial equipment (i.e. dishwashers, laundry equipment, etc.) may require higher temperature settings. Refer to instruction manuals supplied with this type equipment for recommended temperature settings.

Important: Adjusting the thermostat past the 120°F (49°C) setting on the temperature dial (see Figure 13) will increase the risk of scald injury. Hot water can pro- duce first degree burns within:

120°F (49°C) more than 5 min- utes

130°F (54°C) at 20 seconds 140°F (60°C) at 3 seconds 150°F (66°C) at 1-1/2 seconds 160°F (71°C) at less than 1 sec- ond

Each water heater consists of a mechanical tempera- ture stop set to 140°F (60°C). To set to a different set- ting remove the temperature dial knob, loosen the shaft nut and re-position the mechanical temperature stop. Tighten the shaft nut and replace the temperature dial knob.
