| Referring to the illustrated drawing of the central-station hookup for a hot-water heating system, what statement is true concerning the air separator on the heated water outlet of the converter? GS-0151 |
| A) The air separator removes the entrained air introduced within the converter and ultimately released by the expansion tank vent. |
| B) The air separator removes the entrained air introduced by the heating steam and ultimately released by the condensate returns gravity draining to the atmospheric drains tank. |
| C) The air separator removes the entrained air introduced with the makeup water at the expansion tank and ultimately released by the heating process within the converter. |
| D) The air separator removes the entrained air introduced by the heated air via the zone return lines and ultimately released by the heating process within the converter. |
