Indirect-Fired Water Heaters – Series 3
Hot Water Can Scald!
• Water temperature over 125°F can cause severe
burns instantly, or death from scalds.
• Feel water before bathing or showering.
• Consumer Product Safety Commission and
some states recommend temperature settings
of 130°F or less. Setting thermostat higher than
130°F setting will increase risk of scald injury and
can cause severe personal injury or death.
• Water heated to a temperature suitable for
clothes washing, dish washing and other sani-
tizing needs will scald and cause permanent
injury.
• Children and elderly, infirm, or physically handi-
capped persons are more likely to be injured by
hot water. Never leave them unattended in or near
a bathtub, shower or sink. Never allow small chil-
dren to use a hot water faucet or draw their own
bath. 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
recommendations and instructions.
• Use the lowest practical temperature setting.
• Check water temperature after any
adjustment. You must follow “Setting the
Thermostat” on page 19.
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 tempera-
ture after adjusting thermostat.
• When hot water is used in repeated small quantities,
a “stacking” effect can develop in hot water tank.
The upper layer of water in tank can be much hotter
than lower layers.
• Lowering the thermostat setting or installing
automatic mixing valves as indicated in these in-
structions will reduce water temperature levels.
Consult your installer or service technician.
