    Don't hardly ever run across greenheck MUA'S....exhaust fans...heck yeah...plenty. Most of the MUA'S i work on are Rapid, Sterling, Cambridge, Captiveair, Reznor, AAON. Not that there is a huge difference, just nice to get some context on a brand i Don't hardly ever work on for MUA'S. Great video as always Steve.

    Nice man. Your manometer was referencing atmosphere and the burner is on the inlet to the supply fan so it'll be more towards negative/negative the more it turns down. I've never done it, but I guess you could reference the cabinet to get the "true gas pressure" if you were curious. I may try that next one I see lol. Maxitrol has some decent literature on those MR valves. Lots of configurations. Enjoy the content man.

      Thanks for the feedback, and watching! Just like trane negative pressure valves, you are on the outlet side but read a negative pressure.

    Shoddy sheet metal install. Square throat radius heel elbows do not work well when static pressure is a concern. Best to read the manual when designing duct. Great diagnosis. Thxs for the vids!

    Should have a nice offset coming off the top of that unit.
