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.
!
WARNING
If the information in these instructions is not
followed exactly, a fire or explosion may result
causing property damage, personal injury or
death.
WARNING
!
Do not install on combustible flooring. Install
in accordance with all local codes. In the
absence of local codes, refer to ANSI
223.1/NFPA 54 and/or CSA B149.1.
!
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 out-coming temperature
could be based on factors including but not
limited to usage patterns and type of installa-
tion. Test water at the tap nearest to the water
heater. See page 9 for measuring the out-
coming water temperature.
!
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.
