FLAMMABLES

FIRE AND EXPLOSION HAZARD Can result in serious injury or death

Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. Storage of or use of gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance can result in serious injury or death.

Read and follow water heater warnings and instructions.

WARNING

Carbon Monoxide Poisoning Hazard Do not install in a mobile home.

Doing so can result in death or carbon monoxide poisoning.

The FVIR System is designed to reduce the risk of flammable vapor-related fires. Flammable liquids (such as gasoline, solvents, propane, etc,) emit flammable vapors which can be ignited by a gas water heater’s spark igniter or main burner. The resulting flashback and fire can cause death or serious burns to anyone in the area.

Figure 1:

FV Sensor

This heater is equipped with an FV sensor for detecting the presence of flammable vapors. When the sensor detects those vapors, the unit will shut down and not operate. Should this happen, please refer to the troubleshooting guide. Even though this water heater is a flammable vapors

ignition resistant water heater and is designed to reduce the chances of flammable vapors being ignited, gasoline and other flammable substances should never be stored or used in the same vicinity or area containing a gas water heater or other open flame or spark producing appliance. In the event the FVIR system does not prevent the ignition of flammable vapors, the Flame Guard™ Safety System is designed to reduce the risk of flammable vapor-related fires.

The patented Flame Guard™ Safety System protects your family by trapping the burning vapors within the water heater combustion chamber through the special flame-trap. The burning vapors literally “burn themselves out” without escaping back into the room. In the event of a flammable vapor incident, the Flame Guard™ Safety System disables the water heater by shutting off the gas supply to the water heater’s burner and pilot, preventing re-ignition of any remaining flammable vapors in the area. This will not prevent a possible fire/explosion if the igniter activates and flammable vapors have accumulated in the combustion chamber with the pilot light off. If you suspect a flammable vapor incident has occurred, do not use this appliance.

Do not attempt to light this appliance if you suspect flammable vapors have accumulated inside or outside the appliance. Immediately call a qualified person to inspect the appliance. Water heaters subjected to a flammable vapors incident will show a discoloration on the flame-trap and require replacement of the entire water heater. NOTE: Not following these instructions and/or an inadequate air supply can cause the Flame Guard™ Safety System to disable the water heater. Please make required installation and venting/air supply changes prior to resetting the system (see “Combustion Air Supply and Ventilation” section). IMPORTANT: This water heater has a resettable thermal switch installed as part of the Flame Guard™ Safety System. Do not attempt to disable or modify this feature in any way.

Do not use or store flammable products such as gasoline, solvents, or adhesives in the same room or area near the water heater. If such flammables must be used, all gas burning appliances in the vicinity must be shut off and their pilot lights extinguished. Open the doors and windows for ventilation while flammable substances are in use.

If flammable liquids or vapors have spilled or leaked in the area of the water heater, leave the area immediately and call the fire department from a neighbor’s home. Do not attempt to clean the spill until all ignition sources have been extinguished.

Keep combustibles such as boxes, magazines, clothes, etc. away from the water heater area.

Site Location

•Select a location near the center of the water piping system. The water heater must be installed indoors and in a vertical position on a level surface. Do not install in bathrooms, bedrooms, or any occupied room normally kept closed.

•Locate the water heater as close to the chimney or gas vent as practical. Consider the vent system piping and combustion air supply requirements when selecting the water heater location. The venting system must be able to run from the water heater to termination with minimal length and elbows.
