TABLE OF CONTENTS
This water heater is equipped with the FVIR technology. Activation of the FVIR technology occurs when flammable
vapours are drawn into the water heater. If the flammable vapour sensor detects the presence of flammable vapours
when the water heater is operating, the gas control will switch to lock-out mode and the water heater will shut down.
If the water heater is not operating when the flammable vapours are detected, the control will switch to lock-out mode
and prevent the water heater from lighting. If the flammable vapours enter the combustion chamber and ignite, the
flame arrestor will prevent these combustible vapours from igniting outside of the water heater.
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 gas supplier to have
the water heater inspected immediately.
Replacement of a FVIR technology equipped water heater due to a flam-
mable vapour shutdown is not covered under the terms of the Standard Basic Limited Warranty.
