How the calculator treats it
The 800 GPH minimum makes 1-inch plumbing and a properly sized pump especially important.
Capacity basis: Manufacturer publishes 4,020 BTU/h and 800-1,600 GPH flow range.
The engine applies a low-temperature/high-ambient capacity band rather than assuming the nameplate BTU remains exact under every condition. Internal chiller pressure drop is also represented as a range, so a hydraulic PASS is only strong when it survives that uncertainty.
