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
Install in accordance with all local codes. In the
absence of local codes, refer to NFPA 54 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 installation.
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 tempera-
tures 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.
WARNING
Water heater blankets may restrict air flow to the
water heater and cause fire, asphyxiation, personal
injury or death.
