Install Instructions

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 set-
ting 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 sanitizing 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 210º F. This can cause severe personal
injury, death or substantial property damage
if ignored.
