    Does the manometer go before the manual pipe damper (between the furnace and damper) or after? MPD is located about 6 inches from the furnace flue outlet. So if it goes before the MPD it will only be about 3 inches from the furnace flue outlet. Will this location give an accurate reading of the draft?

    Goes between any dampers and the appliance. Otherwise it won't read what the appliance is seeing.
