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.

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. 

• 

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.
