WARNING
Carbon Monoxide Poisoning Hazard
Do not install in a mobile home.
Doing so can result in carbon monoxide poisoning and death.
The Flammable Vapor (FV) Sensor 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.
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 FV Sensor does not
prevent the ignition of flammable vapors, the FVIR System is
designed to reduce the risk of flammable vapor-related fires.
FIGURE 8.
The patented system protects your family by trapping the
burning vapors within the water heater combustion chamber
through the special flame-arrestor. The burning vapors literally
"burn themselves out" without escaping back into the room.
In the event of a flammable vapor incident, the FVIR 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
technician to inspect the appliance. Water heaters subjected
to a flammable vapors incident will show a discoloration on
the flame-arrestor and require replacement of the entire water
heater.

WARNING
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.
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.
WARNING
Fire or Explosion Hazard
• Read instruction manual before installing, using or
servicing water heater.
• Improper use may result in fire or explosion.
• Maintain required clearances to combustibles.
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.
