operation of this furnace. Failure to follow safety 

recommendations could result in possible 

damage to the equipment, serious personal 

injury or death.

 AVERTISSEMENT :

Les renseignements de sécurité indiqués 

ci-dessous doivent être respectés pendant 

l’installation, l’entretien et le fonctionnement 

de cette fournaise. Le non-respect des 

recommandations de sécurité peut causer des 

dommages à l’équipement ou des blessures 

graves, voire mortelles.

 AVERTISSEMENT :

N’installez pas cette fournaise si l’une de ses 

pièces a été immergée dans de l’eau. Une 

fournaise endommagée par une inondation 

est extrêmement dangereuse. Toute tentative 

d’utiliser la fournaise peut entraîner un incendie 

ou une explosion. Il faut communiquer avec un 

organisme de service qualifié pour l’inspection de 

la fournaise et le remplacement de toutes pièces 

électriques ou parties du système de commande 

qui ont été mouillées ou immergées.

 CAUTION:

Operating gas furnaces in construction 

environments can cause a variety of problems 

within the furnace and may significantly 

reduce the life or the performance of the 

furnace. Therefore operating the furnace during 

construction is not permitted and will void the 

warranty.
