Temperature Regulation

A WARNING

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a tem- perature which will satisfy space heating, clothes wash- ing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, shall be used at the hot water taps used by these people or at the water heater. Mixing valves are available at

plumbing supply or hardware stores. Follow manufactur- ers instructions for installation of the valves. Before

changing the factory setting on the thermostat, read the "Temperature Regulation" section in this manual.
