If the air is being sucked in to the house
the smoke travels inwards and there's a nice smoke plume.


Now, I'm confused. If air is being sucked into the house from outside,
wouldn't the pressure inside be greater, and the plume go towards the leak?
Wouldn't the fan have to be sucking air out of the house in order for the
smoke to travel inwards?

I guess it's this simple:

Do you want the smoke to blow towards you, or have it blow towards the leak?

Even on Google, I found directions stating to do it both ways.
