When placing the condenser, make sure the side of the boiler is targeted correctly.
The condenser placed down directly in front of the boiler side that was targeted before.
One grass needs to be placed directly under the boiler to start a campfire.
Just like a regular campfire, it takes 4 firewood on top of the grass pile.
Once filled with alcohol and fired, the boiler will constantly display the progress and fuel needs.
Once a bucket is placed and the condenser is filled with water, it will constantly update the progress and water needs.
