TEMPERATURE REGULATION
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 permanently injured
by hot water than others. These include the elderly, children, the
infi rm, or physically/mentally handicapped. If anyone using hot
water in your home fi ts into one of these groups or if there is a
provincial, state law or local code requiring a specifi c 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
unattended in a bathtub or shower.
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 temperature that
satisfi es your hot water needs. This will also provide the most
energy effi cient operation of the water heater.
Figure 28 shows the approximate water temperatures produced
at various thermostat dial settings. Short repeated heating
cycles caused by small hot water uses can cause temperatures
at the point of use to exceed the thermostat 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.
Valves for reducing point-of-use temperature by mixing cold
and hot water are available (see Figures 2 & 7). Also available
are inexpensive devices that attach to faucets to limit hot water
temperatures. Contact a licensed plumber or the local plumbing
authority.
SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL
TO SHUT OFF, TURN OFF THE MAIN MANUAL GAS CON-
TROL VALVE TO THE APPLIANCE (SEE FIGURE 1).
NOTE: A water temperature range of 49°C-60°C (120°F-140°F)
is recommended by most dishwasher manufacturers. The ther-
mostat of this water heater has been factory set at its lowest
position (PILOT LIGHTING). It is adjustable and must be reset
to the desired temperature setting to reduce the risk of scald
injury. The mark ( ) indicative of approximately 49°C (120°F)
is preferred starting point. Some provinces may have a require-
ment for a lower setting.
Turn the water temperature dial clockwise (
) to decrease the
temperature, or counterclockwise (
) to increase the tempera-
ture.
