I have a question I can't seem to find an answer for online. When I service gas equipment, I normally confirm with the manufacturer if their manifold pressure rating is with the burners on or off. I had an inkling that I might be asking a stupid question if manifold pressure was defined as one or the other.


So just curious, is Manifold Pressure always going to be the gas pressure on the output side of the gas valve with all the burners fired or is it with the burners off.
