HOT WATER CAN SCALD!
• Water temperatures over 125ºF can cause
severe burns instantly, or death from scalds.
• Feel water before bathing or showering.
• Consumer Product Safety Commission and
some states recommend temperatures settings of
130ºF or less. Setting thermostat higher than
130ºF will increase risk of scald injury and
cause severe personal injury or death.
• Water heated to a temperature suitable for
clothes washing, dish washing and other sanitiz-
ing needs will scald and cause permanent injury.
• Children and elderly, infirm, or physically
handicapped persons are more likely to be
injured by hot water. Never leave them unat-
tended in or near a bathtub. If anyone using hot
water in the building fits this description, or if
state laws or local codes require certain water
temperatures at hot water faucets, take special
precautions.
- Install an automatic mixing valve at water
heater or at each hot water faucet, bath and
shower outlet. Selection and installation
must comply with valve manufacturer’s
recommendation and instructions.
- Use the lowest practical temperature setting.
- Check water temperature after any adjust-
ment. You must follow “Adjusting the
Water Heater Thermostat” procedures.
General Notes
• Household water usage patterns will affect
water temperature at any faucet or shower.
Occasionally check temperature at each point
of use, then adjust thermostat accordingly.
Always recheck temperature after adjusting
thermostat.
• When hot water is used in repeated small quan-
tities, a “stacking” effect can develop in the
water heater. The upper layer of water in tank
can be hotter than lower layer.
• Lowering the thermostat setting or installing
automatic mixing valves as indicated in these
instructions will reduce water temperature levels.
Consult your installer or service technician.
At no time should boiler limit control be set
above 210ºF. This can cause severe person-
al injury, death or substantial property
damage if ignored.
