Bock Water heaters 73E - Manual

which could occasionally exceed 120oF. The variation in
outcoming temperature could be based on factors in-
cluding but not limited to usage patterns and type of
installation. Test your water at the tap nearest to the wa-
ter heater.
WARNING: Hotter water increases the risk of scald in-
jury. Before changing the temperature setting, read the
instruction manual. Temperatures at which injury occurs
vary with the individual’s age and length of exposure.
The slower reaction times of children, elderly and phys-
ically or mentally impaired persons increases the
scalding hazard to them. It is recommended lower wa-
ter temperatures be used where these situations exist.
To lower water temperature use point-of-use tem-
perature limiting devices.
WARNING: Flammable vapors may be drawn to this
water heater from other areas of the structure by air cur-
rents. 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 in-
jury or death.
WARNING: Hydrogen gas can be produced in a hot
water system that has not been used for an extended
period–generally, two weeks or longer. To prevent pos-
sible injury under this situation, we recommend that a
hot water faucet be wide open for several minutes
before you use ANY electrical appliance that is connect-
ed 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.
