Before inspecting, diagnosing, repairing or operating
any water heater, be sure to examine all of the safety
and warning labels on the tank. Follow the instruction
on these warning labels. Read and understand the Use
and Care Manual that was shipped with the water
heater. Failure to do so can result in unsafe operation of
the water heater resulting in property damage, bodily
injury, or death. Should you have any problems reading
or following the instructions in the Use and Care
Manual, seek the help of a licensed and qualified professional.
