There are 2 reasons they probably recommend not using an extension cord.

First one is safety. A dedicated outlet with a GFI breaker should be used. You are more likely NOT to use one if you use a cord. Second, If you use a low capacity extension cord you WILL burn out the motor as it can't pass enough current to the motor. This could also explain the burning smell. Additionally, even with a heavy duty cord more or loose connections will also add resistance to the circuit.

Motors are very sensitive to this. It's similar to running your well pump on a generator without enough capacity. It will work but eventually burn out.

This should be a glaring issue for the installer especially on the service call.
