Installation and Operation Instructions Manual
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 water temperature for
normal residential use is 120°F/49°F. Outlet
water temperatures may exceed the thermostat
setting. Measure water temperature at the tap
nearest to the water heater.
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,
and 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.
Such households may require a temperature
setting less than 120°F to prevent accidental
contact with hot water.
To lower water temperature use point-of-use
temperature limiting devices.
WARNING
Water heater blankets are not recommended
and will void the warranty.
CAUTION
This water heater is not intended for space
heating applications.

(135°F - 181°F) and fixed high limits (200°F). Both thermostats are factory set to 135°F. CAUTION: Hot water in excess of 120°F can cause scalding! Bock recommends a thermostatic mixing valve be installed and used according to the manufacturer’s directions to prevent scalding. Many state and local codes now require installation of these devices. - Page 7 SECTION II: GENERAL INFORMATION ANODE RODS The anode rod is used as a sacrificial element within the volume of the storage tank. The purpose of the magnesium anode rod is to protect the inside of the tank against corrosion. Anode rods should be inspected twice in the first year and at least yearly once a time interval for inspection has been developed.
