9. Pressurized Systems
a) Nitrogen pressurization may be used to advantage where the total system content is very
large or in a system operating near or above the vapor pressure of the fluid employed or
if the inlet of the DA tank is not the highest point in the piping system.
b) In conjunction with this system, an automatic venting device must be fitted to the system
expansion tank. Consult Fulton Thermal Corporation for further details.
c) The location for the liquid level switch is a 2-1/2” NPT connection on the same end of the
tank as the inlet. The liquid level switch is supplied and shipped with the unit, and must
be installed by the customer and then wired to the control panel.
Note
If the tank is located outdoors nitrogen is required.
