4. Betjening

The Lennox 43W85 Inducer Motor Assembly operates as an integral part of your HVAC system's combustion process. When a call for heat is initiated, the inducer motor activates to draw combustion air into the burner and push exhaust gases out through the vent system. This creates a negative pressure within the combustion chamber, which is necessary for safe and efficient ignition and burning. The motor will continue to operate throughout the heating cycle and typically run for a short period after the main burner shuts off to purge any remaining combustion gases.
