FILL AND AIR REMOVAL PROCEDURE
1. Close combination shuto /purge valve in supply, all drain cocks, the
shuto valve for the pressure reducing ( ll) valve, and all manual air vents.
2. Open all other system shuto valves and one of the zone valves, the vent
on the combination shuto / purge valve and the shuto valve to the
pressure-reducing ( ll) valve.
3. Water will now begin to ll the system. Air will escape through the vent
on the combination shuto / purge valve. Continue lling until a constant
stream of water (no bubbling) is discharged from the vent.
4. Close the zone valve on the purged loop, and open the zone valve on
the next loop to be purged. When all air has escaped and only water is
discharged, close the zone valve. When all zones have been purged (one at
a time), close the vent on the combination shuto /purge valve.
5. At this point, the system has been initially lled. However, air pockets
may still remain at high points in the system and in heating loops above
the level of the combination shut/o purge valve. It is quite possible,
depending on the particular system that all piping above the combination
shuto /purge valve still contains air. If manual vents are installed on the
system high points, these should be opened to vent these locations. When
only water is discharged from all vents, the initial purging is complete.
6. Open the combination shuto / purge valve (keep the vent closed). With
the gas shuto valve closed, turn on power to the boiler and operate the
circulator. Circulate the system water for approximately 30 minutes to
move all air to the automatic air separation point.
7. Again, open manual air vents at high points of heating loop until a
constant stream of water is discharged from the vent. Close the vent and
make sure it's watertight. Repeat procedure for all high points and for
every zone.
8. Check temperature/pressure indicator reading, which should equal the
pressure-reducing ( ll) valve set pressure. No more water should be
entering the system. Close the shuto valve on the cold-water ll line.
9. Visually inspect all pipe joints and equipment connections for leaks. If
necessary, drain system, repair leaks and re ll/purge the system. If no
pressure drop is detected for a period of two hours under pressure, the
system may be considered watertight.
10. When purging is completed, make sure the following are open—
combination shut-o /purge valve, shuto valve to pressure reducing ( ll
valve), shuto valve in cold water ll line, and shuto valve in return line.
11. Make sure the following are closed - all drain cocks, the vent on the
combination shuto -purge valve, & all manual vents. Reset zone valves to
normal mode of operation and turn o power to boiler.
12. Open fuel shuto valve, allowing fuel to ow to boiler.
