Changes can be made by adjusting the manifold pressure, or changing
orifices (orifice change may not always be required). To adjust the
manifold pressure:
1. Turn off all electrical power to the system.
2. Loosen (Do Not remove) the pressure tap test set screw one turn
with 3/32" hex wrench.
a. The pressure tap adjustment kit (KIT07611) contains a 3/32"
hex wrench, a 5/16" hose and a connector and can be
