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 flammable vapour shutdown is not covered under the terms of the Standard
Basic Limited Warranty.
Flammable Vapour Sensor
Do not remove the protective cover. Do not spray water or leak detector
products on this sensor. Do not expose this sensor to bleach or other liquid
cleaning products. Avoid humid environments and freezing temperatures.
If the sensor detects the presence of flammable vapours, the gas control will
switch to lock-out mode and the water heater will shut down. Do not try and
restart the water heater. Have the water heater inspected immediately by a
qualified service technician or the gas supplier.

!
Détecteur de vapeurs inflammables
Ne pas retirer le couvercle protecteur. Ne pas vaporiser d'eau ni de produits
détecteur de fuites sur le détecteur. Ne pas exposer le détecteur à un
javellisant ou à tout autre produit nettoyant liquide. Éviter les endroits
humides et les températures sous le point de congélation.
Si le détecteur décèle la présence de vapeurs inflammables, le contrôle au
gaz se verrouillera et le chauffe-eau cessera de fonctionner. Ne tentez pas
de le remettre en marche. Faites inspecter le chauffe-eau immédiatement
par un technicien de service qualifié ou le fournisseur de gaz.
