Carbon Monoxide Poisoning Hazard
Do not install in a mobile home.
Doing so can result in death or
carbon monoxide poisoning.
The Flame Lock™ 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 Flame Lock™ Safety System
shuts 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 disable the water heater until
the system is reset. Note: Not following these instructions
and/or an inadequate air supply can cause the Flame
Lock™ Safety System to disable the water heater. Please
make required installation and venting/air supply changes
prior to resetting the system.
IMPORTANT: This water heater has a resettable thermal
switch installed as part of the Flame Lock
DO NOT attempt to disable or modify this feature in any
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
Keep combustibles such as boxes, magazines, clothes,
etc. away from the water heater area.
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.
Locate the water heater near the existing gas piping.
If installing a new gas line, locate the water heater to
minimize the pipe length and elbows.
NOTE: This water heater must be installed according to all
local and state codes or, in the absence of local and state
codes, the "National Fuel Gas Code", ANSI Z223.1(NFPA
