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

This is the safety alert symbol.

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

“WARNING.” These words mean:

All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you 
what can happen if the instructions are not followed.

• 

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 any time 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  
monoxide, and soot.
