Warranty and registration card included
WARNING: Improper installation, adjustment, alteration,
service or maintenance can cause serious injury or proper-
ty damage. Refer to this manual. For assistance or addi-
tional information, consult a qualified installer or service
agency.
WARNING: If the information in these instructions is not
followed exactly, fire or explosion may result and can cause
property damage, personal injury or death.
DO NOT INSTALL THE WATER HEATER ON COM-
BUSTIBLE FLOORING. Install in accordance with all local
codes. In the absence of local codes, refer to NFPA 31 or
ANSI Z21.10.1, or contact Bock Water Heaters with
questions concerning proper flooring materials.
Minimum clearance to combustible construction is:
SIDES 6”; BACK 6”; FRONT 24”. The installation of
this water heater must conform with local codes and
ordinances. In the absence of local codes, the installa-
tion must comply with the National Fire Protection
Association (NFPA 31) Code.
WARNING: The recommended temperature for normal res-
idential use is 120°F. The dial on the aquastat does not
always reflect the outcoming water temperature, which
could occasionally exceed 120°F. The variation in outcom-
ing temperature could be based on factors including but not
limited to usage patterns and type of installation. Test your
water at the tap nearest to the water heater.
WARNING: Hotter water increases the risk of scald injury.
Before changing the temperature setting, read the instruc-
tion manual. Temperatures at which injury occurs vary with
the individual’s age and length of exposure.
The slower reaction times of children, elderly and physically
or mentally impaired persons increases the scalding hazard
to them. It is recommended lower water temperatures be
used where these situations exist.
To lower water temperature use point-of-use tempera-
ture limiting devices.
WARNING: Flammable vapors may be drawn to this water
heater from other areas of the structure by air currents. Do
not store or use any flammable liquids in the vicinity of
this heater.
WARNING: Water heater blankets may restrict air flow to
the heater and cause fire, asphyxiation, personal injury or
death.
WARNING: Hydrogen gas can be produced in a hot water
system that had not been used for an extended period-gen-
erally, two weeks or longer. To prevent possible injury
under this situation, we recommend that a hot water faucet
be wide open for several minutes before you use ANY elec-
trical appliance that is connected to the hot water system.
If hydrogen is present, an unusual sound – such as air
escaping – will come from the open faucet as the hot water
begins to flow. Hydrogen gas is extremely flammable –
there must be no open flame near this open faucet.
