Page 7: General Safety
GENERAL SAFETY To meet commercial hot water use needs, the high limit safety control on this water heater will shut off the main gas valve before the outlet temperature reaches 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. -
