GENERAL SAFETY To meet commercial hot water use needs, the high limit safety control on this water heater is adjustable up to 210°F. However, water temperatures over 125°F can cause instant severe burns or death from scalds. When supplying general purpose hot water, the rec- ommended initial setting for the temperature control is 125°F.
Stacking The temperature of the water in the heater can be reg- ulated by adjusting the setpoint, this process is fully described in the manual in the “Controls” section (see Hi Delta units can be stacked two units high with an page 47).
