Combustion Intake air. The duct doesn’t have to be round or a single inlet. The requirement is that the total
inlet area must be equal to 16sq.in. or greater.
This air must enter the chase no higher than 12” [305mm] from the bottom of the fireplace. And can be placed
on the front (off to the side of the unit "Figure 44: FP30 Crafstman Installed." or on the sides or back of the
chase if it protrudes into the room. Air can be drawn from under the chase, if that space is sealed within the
house envelope. The air must come from inside the house, preferably the room the fireplace is installed in.
