SUMMARY
The discussion focuses on the operational procedure for starting up a furnace, specifically the role of the FD fan upstream valve and its impact on fan torque. The vendor's instructions dictate that the upstream valve should be closed initially to enhance fan torque during startup. This approach reduces fan speed and increases motor slip, effectively managing starting torque and inrush current while minimizing thermal shock to the electric motor.
