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 set-
tings 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 san-
itizing 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
unattended 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 set-
ting.
- Check water temperature after any
adjustment. 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.
