Figure 4: VORTEX Eco Wall Hung boiler (showing water fill point valve with cap)
To re-pressurise the system by adding
water:
1. Only add water to the system when
it is cold and the boiler is off. Do not
overfill.
2. Check that the fill point valve is
closed as shown by the large arrow
in Figure 4.
3. Remove the cap shown with a
suitable spanner.
4. Ensure that the flexible filling loop
supplied with the boiler (see Figure 4)
is connected and that the double
check shut off valve connecting it to
the water supply is closed. (A valve is
open when the operating lever is in
line with the valve, and closed when
it is at right angles to it).
5. Open the fill point valve shown in
Figure 4.
6. Gradually open the double check
valve from the water supply until
water is heard to flow.
7. When the white needle of the
pressure gauge is between 0.5 and
1 bar, close the valve.
8. Vent each radiator in turn, starting
with the lowest one in the system,
to remove air.
9. Continue to fill the system until the
pressure gauge indicates between
0.5 and 1.0 bar. Close the fill point
valve.
10. Repeat steps 6 and 7 as required.
11. Close the fill point and double check
valves either side of the filling loop
and disconnect the loop.
12. Refit the cap to the fill point valve
shown by the large arrow in Figure 4.
