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.

Incorrect operation of this appliance may create a hazard to life and property and will nullify the warranty. DO NOT operate this water heater if the input rate exceeds the rate shown on the water heater rating plate. This water heater contains very hot water under high pressure. Do not unscrew any pipe fittings nor attempt to disconnect any components of this water heater without positively assuring the water is cool and is not under pressure. Always wear protective clothing and equipment when installing, starting up or servicing this water heater to prevent scald injuries. Do not rely on the temperature gauges to determine the temperature. Do not touch any components unless they are cool.

This water heater must be properly vented and connected to an approved vent system in good condition. DO NOT operate water heater with the absence of an approved vent system.
