WARNING: SCALD HAZARD
The risk of scald injury increases as you increase water
temperature. A lower setting is more economical and
reduces the risk of scalding. Use a water tempering or
mixing valve and extreme caution when using hot water to
avoid scald injury. Consult codes for conformance. Failure
to follow the instructions in this warning statement could
result in serious personal injury or death from scalds.
NOTICE: PRODUCT DAMAGE
If draining of the water heater is necessary, open the T&P
valve or a hot water tap to prevent vacuum buildup in the
heating canister and piping.
