DANGER
DO NOT store or use gasoline or other flammable, combustible, or corrosive vapors and/or liquids in the vicinity of
this or any other appliance.
This water heater is equipped with an adjustable thermostat to control water temperature. Hot water temperatures
required for automatic dishwasher and laundry use can cause scald burns resulting in serious personal injury and/or
death. The temperature at which injury occurs varies with the person’s age and the time of exposure. The slower
response time of disabled persons increases the hazards to them. NEVER allow small children to use a hot water
tap, or to draw their own bath water. NEVER leave a child or disabled person unattended in a bathtub or shower.
Toxic chemical, such as those used for boiler treatment, must not be introduced into potable water used for space
heating.
This water heater must not be connected to an existing heating system or component(s) previously used with a non-
potable water heating appliance.
All piping components connected to this water heater for space heating applications must be suitable for use with
potable water.
