measurements.

You can use those values to get your temperature rise, which tells you how well the appliance is heating the air. (That's kind of like the delta T of heating.) You won't take your official temperature rise until later, as there are a few extra steps involved with temperature rise, but you can get an idea of the unit's average performance early on.

As a rule of thumb, it's a good idea for the static pressure to be less than the maximum specification listed on the data tag. 12. Read your inlet and outlet gas pressures. As stated earlier, you can find the rated gas pressures on your data tag so that you know what those values should be when you test the gas pressure.
