TABLE OF CONTENTS
This water heater is equipped with new 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 an FVIR technology equipped water
heater due to a flammable vapour shutdown is not covered under the terms of the Standard
Basic Limited Warranty.
