Electric vent dampers have a small electric motor that drives the damper. It is spring loaded such that if the electric power or the motor fails, the damper will fail open. The damper motor is wired in with the gas value. When the gas valve opens and the burner ignites, the vent damper opens. When the burner is shut off, so is the vent damper.
