John Wood Polaris Commercial High-Efficiency - Manual (Page 2)

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 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:
Indicates an imminently hazardous situation which, if not
avoided, will result in death or injury.
Indicates a hazardous situation which, if not avoided,
could result in death or serious injury.
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.
Important Instructions
• Do not use this water heater 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 ignition control 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.
