SERVICE AND MAINTENANCE
Temperature Regulation
HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, 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, some type of tempering device, such as a mixing valve, should 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 manufacturers instructions for installation of the valves, Before changing the factory setting of the thermostat, read the “Temperature Regulation” section in this manual.
Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unattended in a bathtub or shower.
Thermostat
The thermostats of this water heater have been factory set at the “HOT” position which approximates 120°F (49°C). The thermostats are adjustable if a different water temperature is desired. Read all warnings in this manual and on the water heater before proceeding.

Temperature Setting | Burns on Adult Skin |
VERY HOT = APPROX.160°F (71°C) | About 1/2 second |
C = APPROX.150°F (65°C) | About |
B = APPROX.140°F (60°C) | Less than 5 seconds |
A = APPROX.130°F (54°C) | About 30 seconds |
HOT = APPROX.120°F (49°C) | More than 5 minutes |
Thermostat Adjustments
The upper and lower thermostats have been factory set at HOT approximately 120°F (49°C) to reduce the risk of scald injury.
