IV) OPERATING INSTRUCTIONS Water Temperature Regulation

HOT WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature that will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be perma- nently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handi- capped. If anyone using hot water in your home fits into one of these groups or if there is a provincial, state law or local code requiring a specific hot water temperature at the tap, then you must take special precautions. Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unat- tended in a bathtub or shower.

Temperature Adjustment

The thermostat of this water heater has been factory set at its lowest position. It is adjustable and must be set to the desired temperature setting. The preferred starting point is 49°C (120°F). Turn the water temperature dial clockwise

to decrease the temperature, or counterclockwise to increase the temperature.

Figures 13a & 13b show the approximate water tempera- tures produced at various thermostat settings. Short repeat- ed heating cycles caused by small hot water uses can cause temperatures at the point-of-use to exceed the ther- mostat setting by up to 17°C (30°F). If you experience this type of use you should consider using lower temperature settings to reduce scald hazards. Should overheating occur or the gas supply fail to shut off, turn off the manual gas con- trol valve to the appliance.

DANGER

Water temperature over 52°C (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 available.

It is recommended that lower water temperatures be used to avoid the risk of scalding. It is further recommended, in all cases, that the water temperature be set for the lowest tem- perature that satisfies your hot water needs. This will also provide the most energy efficient operation of the water heater.

WARNING

Risk of scalding

There is a hot water scald potential if the thermostat is set too high.

Adjusting the thermostat past the 49°C (120°F) bar on the temperature dial will increase the risk of scald injury

Hot water can produce third degree burns in 6 seconds at . . . . . . . .60°C (140°F) in 30 seconds at . . . . . . .54°C (130°F) in 5 minutes at . . . . . . . . .49°C (120°F)

Valves for reducing the point-of-use temperature by mixing cold and hot water are available (see Figure 2). Also avail- able are inexpensive devices that attach to faucets to limit hot water temperatures. Contact a licensed plumber or the local plumbing authority.

Note: During low demand periods, a lower thermostat set- ting will reduce energy losses and may satisfy your normal hot water needs. If hot water use is expected to be more than normal, a higher thermostat setting may be required to meet the increased demand. When leaving your home for extended periods (e.g., vacations etc.) turn the temperature dial to its lowest setting. This will maintain the water at low temperatures with minimum energy losses and prevent the tank from freezing during cold weather.
