FVIR technology equipped with flame arrestor
This water heater is equipped with the new FVIR technology. In the event that gasoline or other flammable
vapours and liquids are improperly stored in the area where the water heater is located, the flame arrestor will
prevent these combustible vapours from igniting outside of the water heater.
Activation of the FVIR technology occurs when flammable vapours are drawn into the combustion chamber of
the water heater and ignite. If flammable vapours are detected:
• DO NOT try to light any appliance.
• DO NOT touch any electrical switch, DO NOT use any phone in your building.
• From a neighbour’s phone, immediately call your gas supplier. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
After the flammable vapours have been evacuated, contact a qualified service technician or the manufacturer
for further instructions. Replacement of a FVIR technology equipped water heater due to a flammable
vapour shutdown is not covered under the terms of the Standard Basic Limited Warranty.
