There are several diagrams in this section that should help. After I looked they appear to be threaded.

The link was helpful. Thank you. Since they are obviously threaded, the question was if they were hose or NPT. the answer is:
All connection ports are ½” Male NPT fittings for easy installation of Pex adapters, Flare-It adapters, or flexible connectors with or without conical seal washers.
