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 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 included in the Act.

Unpacking the Water Heater
WARNING
Excessive Weight Hazard
Use two or more people to move and install
water heater unless proper handling
equipment is utilized
Failure to do can result in back or
other injury. 4
Location Requirements
The FVIR Safety System is designed to reduce the risk
of flammable vapor-related fires. The patented 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 FVIR Safety System
disables the water heater by shutting off the gas supply to
the water heaters 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 is
depressed 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,
or depress the igniter button 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.
Do not use or store flammable products such as gasoline,
solvents, or adhesives in the same room or area near the
Carbon Monoxide Poisoning Hazard
Do not install in a mobile home.
Doing so can result in death or
carbon monoxide poisoning.
