Initial start−up, inspection and maintenance
Further details regarding the individual steps
Starting the heating system
Operating instructions, service instructions control unit and burner
1. Check that the boiler room
ventilation aperture is open.
2. Check the inlet pressure of the
diaphragm expansion vessel.
If the inlet pressure of the
diaphragm expansion vessel is
lower than the static system
pressure, top up with enough
nitrogen to raise the inlet pressure
higher than the static system
pressure (0.1 to 0.2bar).
The static pressure corresponds to
the static head.
3. Open the check valves.
4. Top up your heating system with
water and vent it, until the
pressure is higher (0.1 to 0.2bar)
than the inlet pressure of the
diaphragm expansion vessel.
Permiss. operating pressure:3bar
5. Mark this pressure at pressure
gaugeA.
6. Return the check valves to their
operating position.
7. Open the oil or gas shut−off valves.
