HVAC/ HYDRONICS
2. Put the control and the #111 back on the sub-base.
3. Place the switch in the 'OFF' position. This will put the
burner into "Pre-Purge" mode.
4. After the pre-purge period the oil valve will energize. At this
time, place the switch in the "ON" position.
5. The oil will now leave the pump and enter the receiving container.
Note: There should be flow from the nozzle and all air should
be purged from the pump. The use of an oil line from the nozzle
port to the purging can may speed this process.
Note: On some gravity systems with little to no restriction
in the system the use of a jumper between terminals 5 and 6 of
the sub-base without the control installed MAY
also bleed the pump. The use of a CATIII 600Vac
jumper like that shown in Figure 8 (available
from us) is recommended to protect the techni-
cian from line voltage. The gravity procedure will
not work with an oil safety valve or check valve
in the line(s) and any overhead line that travels
above the tank.
TWO-PIPE SYSTEMS
Normally when the pump is set up for two-pipe
operation it will self-purge after a few safety resets. This includes
installations equipped with a de-aerator. The #111 will speed up
the process. The burner will also provide an audible as well as
visual notice that the pump is bled by opening the damper (if
equipped) through the piston. However if a large amount of air
is present in the system the pump should be bled using a #111
Cad-cell Deviator.
NOTE: Use of the #111 Deviator Switch shuts off the burner
ignition system, so again the use of an oil line placed into the noz-
zle port and ending in the priming can is recommended, Figure 9.
The #111 makes priming a Riello pump in any vacuum appli-
cation easy and you can find more about it on our website. It's a
real time saver and is only $15.00, plus shipping. Work smarter,
work faster, make more money.
See ya.
