Welcome to the forums.

That is not a home heating unit. That is a commercial rooftop unit. We deal with basic home furnaces here. That unit requires a specialized high volume regulator. I left you a link to the manual. In it describes the size of the regulator you need.

See installation and piping on page 32.
