CA 2213283

A furnace for combustible fuels that incorporates a main igniter and an auxiliary back-up igniter for igniting the fuel. When power is applied to the main igniter, a sensor detects whether or not current flows through the main igniter. If there is current flow through the main igniter, the back-up igniter is isolated from the input power. If there is an absence of current flow through the main igniter, the power is switched to the auxiliary back-up igniter. A warning device is provided to alert a user when the power has been switched to the back-up igniter indicating that the main igniter is inoperable.

Appareil de chauffage pour carburant combustible qui intègre un allumeur principal et un allumeur d'appoint auxiliaire permettant d'allumer le carburant. Lorsque l'allumeur principal est alimenté, un capteur vérifie si le courant passe dans l'allumeur principal. S'il y a courant, l'allumeur d'appoint est isolé de la puissance d'entrée. S'il n'y a pas de courant, la puissance est commutée à l'allumeur d'appoint. Un dispositif d'avertissement permet d'alerter l'utilisateur lorsque le courant a été commuté à l'allumeur d'appoint, ce qui indique que l'allumeur principal ne fonctionne pas.
