I'm guessing you're only using 2 firefighters. This does mean less time between moving, and less chance of getting burnt. But what I found when I was first learning the board game, 3-4 firefighters was easier. You can more effectively cover the whole house, and when you're learning, fire management is key. So start by putting out as much of the fire as possible, and then focus on learning to keep the fire under control. Learning fire management can take time, but as you learn to work together it will become easy.
