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.
NOTICE: This unit is equipped with a Flammable Vapor Sensor. Venting installation of
this flammable vapor ignition resistant water heater involves the use of PVC glue. PVC
glue emits flammable vapors. Do not apply power until enough time has passed to allow the
vapors from the PVC primer and cement to dissipate. Installation in locations with ambient
air over 100 degrees F may lock out the controls.
