WARNING

Improper installation, adjustment, alteration,
service or maintenance can cause serious
injury or property damage. Refer to this
manual. For assistance or additional
information, consult a qualified installer or
service agency.

CAUTION

The recommended temperature for normal
residential use is 120

°

F. The dial on the aquastat

does not always reflect the out-coming water
temperature and it could occasionally exceed
120

°

F. Variation in outcoming temperature

could be based on factors including, but not
limited to, usage patterns and type of
installation. Test water at the tap nearest to 
the water heater and storage tank.

WARNING

Hotter water increases the risk of scald injury.
Before adjusting the water temperature setting,
read this instruction manual. Temperatures at
which injury occurs vary with the person’s age
and the length of exposure. The slower
reaction time of children, elderly, or
physically or mentally challenged persons
increases the scalding hazard to them. It is
recommended that lower water temperatures
be used where these exposure hazards exist.
Households with small children or invalids
may require a temperature setting less than
120

°

F to prevent accidental contact with hot

water. To produce less than 120

°

F, use point-of-

use temperature limiting devices.
If higher water temperature is needed in part
of the water system, automatic temperature
limiting devices must be used on all lines to
water taps.
