10Automatic air vent (with diaphragm-type expansion tank), or connect to tank ﬁtting (closed-type expansion tank). DO NOT use an automatic air vent when using closed-type expansion tank. It would allow air to leave the system, causing waterlog- ging of the expansion tank.

11Fill valve

12Diaphragm-type or bladder-type expansion tank, if used (For closed-type expansion tank, pipe from top of air separator to tank ﬁtting as in Figure 5, page 15.)

13Air separator and automatic vent, if used (Note that the ﬁll valve must always be connected to the expansion tank, regardless of location of expansion tank, circulator or air separator.)
