Your safety and the safety of others are very important.

We have provided many important safety messages in this manual and on your appliance. Always read and obey all

safety messages.

This symbol alerts you to potential hazards that can kill or hurt you and others.
All safety messages will follow the safety alert symbol and either the word “DANGER” or

Important Instructions

·

Do not use this appliance if any part has been under water. Immediately call a qualified service 

technician. Water heaters subjected to flood conditions or anytime the gas controls, main burner or pilot have 

been submerged in water require replacement of the entire water heater.

·

Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally

two weeks or more). Hydrogen gas is extremely flammable and can ignite when exposed to a spark or flame. 

To prevent the possibility of injury under these conditions, we recommend the hot water faucet be opened for 

several minutes at the kitchen sink before using any electrical appliance which is connected to the hot water 

system. If hydrogen is present, there will probably be an unusual sound such as air escaping through the faucet

as water begins to flow. Do not smoke or have any open flame near the faucet at the time it is open.

The California Safe Drinking Water and Toxic Enforcement Act requires the Governor of California to publish a list of

substances known to the State of California to cause cancer, birth defects, or other reproductive harm, and requires

businesses to warn of potential exposure to such substances.

Warning:

  This product contains a chemical known to the State of California to cause cancer, birth defects, or other

reproductive harm.
This appliance can cause low-level exposure to some of the substances listed, including formaldehyde, carbon monxide,

and soot.
