10. Connections
a) The vent connection must be made in a manner that will prevent penetration of water or
foreign bodies into the tank. This connection must always terminate in a safe, well
ventilated area and has to be free of obstruction, open to atmosphere, and arranged in
such a manner that, in the event of discharge from the system, thermal fluid could drain
into a catch tank without danger to personnel or property.
Note
Non-code tanks cannot be pressurized over 15 psig.
Warning
High temperature thermal fluid, steam and combustible vapors may be vented
through this connection.
b) The vent run should be the same size as the tank outlet. It should run pitch down from
the outlet of the tank to the catch tank.
c) If nitrogen is used on the system, the vent can be reduced and should be piped with a
positive closing valve at the catch tank.
