Carbon Monoxide Poisoning Hazard
WARNING
Do not install in a mobile home.
Doing so can result in carbon monoxide poisoning and death.
The FVIR 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-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
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 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
Flammable Vapors
FLAMMABLES
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
FIRE AND EXPLOSION HAZARD
Can result in serious injury or death
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.
Fire or Explosion Hazard
WARNING
• 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.
•
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.
•
The water heater should be located in an area not
subject to freezing temperatures. Water heaters
located in unconditioned spaces (i.e., attics,
basements, etc.) may require insulation of the water
piping and drain piping to protect against freezing.
The drain and controls must be easily accessible for
operation and service. Maintain proper clearances as
specified on the rating plate.
•
Do not locate the water heater near an air-moving
device. The operation of air-moving devices such
as exhaust fans, ventilation systems, clothes dryers,
fireplaces, etc., can affect the proper operation of the
water heater. Special attention must be given to condi-
tions these devices may create. Flow reversal of flue
gases may cause an increase of carbon monoxide
inside of the dwelling (Figure 1).
•
If the water heater is located in an area that is
subjected to lint and dirt, it may be necessary to
periodically clean the base-ring filter and flame-
arrestor (see External Inspection & Cleaning of the
Flame-arrestor).
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
54)-current edition.
